Naoyuki Uwasawa

Details On Naoyuki Uwasawa’s Rays Contract

By Mark Polishuk | January 21, 2024 at 4:16pm CDT

The Rays agreed to a minor league deal with right-hander Naoyuki Uwasawa earlier this month, as Uwasawa will test his fortunes in the majors after nine seasons with the Hokkaido Nippon-Ham Fighters of Nippon Professional Baseball. The contract’s terms weren’t reported at the time, but MLB.com’s Adam Berry has the details on what is actually a split contract for the Japanese righty.

Uwasawa will earn $225K while in the minors and $2.5MM for his time on the big league roster. He also receives a $25K signing bonus up front, and up to $1MM in incentive bonuses based on innings pitched. The first bonus level of $100K would be unlocked if Uwasawa pitches 70 innings for the Rays, and he’d then receive an additional $100K for each additional ten innings pitched up to the 160-inning threshold.

Tampa Bay also owe the Fighters a posting fee, though the exact total of that fee has yet to be determined given the largely non-guaranteed nature of Uwasawa’s contract. For now, the Fighters will receive the equivalent of one-quarter of Uwasawa’s signing bonus, and then will eventually be paid 15% of whatever Uwasawa ends up making during the 2024 season.

Interestingly, Berry reports that Uwasawa opted to take this contract over guaranteed offers from other MLB teams. It isn’t know what other offers might have entailed in terms of money, length, or any number of other factors that might’ve led Uwasawa to prefer Tampa’s offer, but it might have simply come down to the fact that Uwasawa had particular interest in joining the Rays. As per his statement at the time of the signing, Uwasawa “decided to play for the Rays because the success and the rich history of pitching development really intrigued me,” so it could be that Uwasawa decided to somewhat bet on himself in taking a slightly lesser deal in order to land on one of his preferred options.

The relationship between the two sides could also technically end before Opening Day, as Marc Topkin of the Tampa Bay Times writes that the contract contains an out clause at the end of Spring Training. However, in all likelihood the out clause is just a formality of minor league deals and Uwasawa will choose to stay in the Rays organization, even if he doesn’t necessarily break camp with the team. The Rays could use Uwasawa in the minors to get him acclimated to North American baseball and to see how his stuff plays in a proper game setting before giving him a look on the active roster.

Uwasawa posted a 3.19 ERA over 1118 1/3 career innings with the Fighters, delivering both quality results and durability — he has thrown at least 160 innings in four of the last five full NPB seasons. With only a 19.7% career strikeout rate and a fastball that averaged under 91mph last season, there are concerns from evaluators about whether or not Uwasawa will be able to fool MLB hitters as successfully as he did in Japan. But, as Berry and Uwasawa himself observed, the Rays have such a strong reputation for developing and/or getting pitchers on track that it seems entirely possible that Uwasawa could blossom under the team’s wings.

Rays Sign Naoyuki Uwasawa To Minor League Deal

By Darragh McDonald | January 11, 2024 at 9:30pm CDT

The Rays announced that they have signed right-hander Naoyuki Uwasawa to a minor league contract with an invite to major league camp. “I’m excited to join the Rays organization and grateful for the opportunity to begin a career in Major League Baseball,” he said in a club press release. “I decided to play for the Rays because the success and the rich history of pitching development really intrigued me.”

Uwasawa, 29, will be coming over from the Nippon Ham Fighters of Japan’s Nippon Professional Baseball. Like Yoshinobu Yamamoto and Shota Imanaga, he was posted by his NPB club, but he comes with decidedly less hype than those two. While Yamamoto secured himself a $325MM contract and Shota Imanaga landed a $53MM guarantee, Uwasawa is settling for a minor league pact.

That may be a surprise if one were to merely look at Uwasawa’s results in terms of run prevention. He has a 3.19 earned run average over his nine NPB seasons, having tossed over 1,000 innings. He just posted a 2.96 ERA over 170 innings in 2023.

But digging a little deeper shows why there wasn’t as much excitement from MLB clubs. MLBTR contributor Dai Takegami Podziewski has frequently highlighted Uwasawa in his NPB Players to Watch series, noting that his fastball was averaging just 90.8 miles per hour last year.

That’s perhaps a factor in his low strikeout totals in Japan. His NPB career has resulted in a strikeout rate of just 19.7% while that was down to 17.8% in 2023. For reference, Yamamoto punched out 26.6% of hitters last year while Imanaga was at 29.2%. Since MLB hitters are considered superior to NPB hitters, it’s understable that clubs would be suspicious of how Uwasawa would make the jump to North America.

That doesn’t necessarily mean Uwasawa is doomed to failure, as some pitchers are crafty enough to succeed without a power arsenal, with Kyle Hendricks and Brent Suter just a couple of examples. But throwing harder generally gives a pitcher more room for error than one with a bit less power.

For the Rays, there’s no risk in giving him a minor league deal to see how his stuff plays against hitters in the affiliated ranks. Their rotation has taken a number of hits in the past year, as each of Shane McClanahan, Jeffrey Springs and Drew Rasmussen required a serious elbow surgery that will force them to miss part or perhaps all of the 2024 season. The club’s financial situation also led them to trade Tyler Glasnow to the Dodgers.

They are currently left with a rotation featuring Zach Eflin, Aaron Civale, Zack Littell, Ryan Pepiot, Taj Bradley and Shane Baz. Eflin and Civale have checkered health histories while Littell only recently converted from the bullpen to a starting gig. Pepiot and Bradley are lacking in big league experience while Baz is coming off a season completely lost to Tommy John surgery recovery.

If Uwasawa is in good form in the spring and in the early parts of the minor league season, there should be plenty of opportunity for him to find some big league innings, whether that’s in the rotation, behind an opener or perhaps as a multi-inning guy out of the bullpen.

Rays Interested In Naoyuki Uwasawa

By Mark Polishuk | December 17, 2023 at 5:27pm CDT

With the Tyler Glasnow trade now finalized and Ryan Pepiot a part of the Rays’ pitching mix, the team is continuing to look for pitching help. Marc Topkin of the Tampa Bay Times reports that “the Rays have some interest in” Naoyuki Uwasawa, whose 45-day posting window is up on January 11.

Tampa becomes the seventh MLB team known to have some level of interest in the right-hander, as a Sports Hochi report (Japanese language link) in September revealed that the Angels, Cubs, Diamondbacks, Rangers, Reds, and Royals all had scouts watching one of Uwasawa’s starts for the Nippon Ham-Fighters. It is probably safe to assume even more teams have some level of interest in Uwasawa due to both his track record in Nippon Professional Baseball, and the fact that he might have a relatively low price tag in comparison to many other free agent pitchers on the market.

Uwasawa (who turns 30 in February) had a 3.19 ERA over 1118 1/3 career innings in NPB, all with the Fighters from 2014-2023. Though it took a few years for the righty to fully establish himself on the Fighters’ roster, Uwasawa’s results have always been pretty solid, and his 2.96 ERA over 170 innings in 2023 represented a career best. Uwasawa is a three-time NPB All-Star, including a nod this past season.

The two big knocks against Uwasawa from a Major League scouting perspective are his lack of strikeouts (19.67% strikeout rate) and a lack of velocity. Uwasawa’s average fastball clocked in at around 90.8mph in 2023, according to MLBTR’s Dai Takegami Podziewski in the September edition of the NPB Players To Watch feature. While Uwasawa has solid control and obviously his contact-heavy approach has led to great success in Japan, whether or not his stuff will be able to fool MLB hitters over the long term is surely a question front offices are asking themselves as they consider offers.

The Rays have a long history of helping pitchers either achieve new levels of success or turn their careers around entirely, so one would imagine they could be a particularly solid landing spot for a pitcher making the transition from NPB to MLB. Tampa Bay doesn’t have a lengthy history with Japanese pitchers or the posting system in general, yet broadly, any intriguing player who represents something of a bargain signing would appeal to a Rays team that is always looking to keep a limited payroll.

Signing Uwasawa would cost the Rays or any MLB team an additional posting fee to the Fighters, on top of whatever Uwasawa himself would earn in a contract. The Fighters’ release fee would be worth 20% of the contract’s first $25MM, 17.5% of the deal’s next $25MM, and then 15% of any money beyond $50MM. If Uwasawa doesn’t agree to a Major League contract by the end of his 45-day posting window, he would return to the Fighters for the 2024 NPB season.

NPB’s Nippon-Ham Fighters Post Naoyuki Uwasawa For MLB Clubs

By Steve Adams | November 27, 2023 at 12:49pm CDT

The Nippon-Ham Fighters of Japan’s Nippon Professional Baseball have posted right-hander Naoyuki Uwasawa for Major League teams, tweets Mark Feinsand of MLB.com. The Fighters announced in October that they would honor the 29-year-old righty’s wishes to be posted. Like Yokohama BayStars left-hander Shota Imanaga, who was also formally posted today, Uwasawa’s 45-day posting window will now kick off tomorrow morning.

Uwasawa, who’ll turn 30 in January, logged 170 innings of 2.96 ERA ball this past season, albeit with a sub-par 17.8% strikeout rate that could temper some enthusiasm. His career mark of 19.7% is a bit better but still not the type of rate that generally catches they eyes of MLB front offices in a market that heavily rewards power arms with swing-and-miss stuff. Uwasawa does sport a sharp 7.5% walk rate in his career, including a particularly impressive 5.9% mark this past season.

Back in September, MLBTR contributor Dai Takegami Podziewski noted that Uwasawa’s fastball velocity on the year was averaging 90.8 mph. Paired with his pedestrian strikeout rate, that lack of velocity will give Major League teams some trepidation about how he’ll stack up against MLB opposition. The average MLB fastball among starting pitchers in 2023 was 93.8 mph — 94.2 mph if focusing in solely on right-handed starters.

Of course, that doesn’t entirely rule out success. Kyle Hendricks sat at an average of 87.8 mph with his “heater” this past season, while fellow righties like Bryce Elder (90.7 mph), Dane Dunning (90.6 mph) and Kenta Maeda (91 mph) were all in the same general vicinity as Uwasawa over the course of generally successful seasons. The majority of right-handed starters who sat in this range struggled, but as with all rules, there are exceptions. Uwasawa could well prove to be such an exception, and his broader track record in Japan could still pique some team’s interest — particularly if (as is expected) his price tag is considerably lower than the other, higher-profile NPB arms who are being posted.

In parts of nine NPB seasons, Uwasawa has amassed 1118 1/3 innings of 3.19 ERA ball with a 19.7% strikeout rate and 7.5% walk rate. He’s been particularly effective in recent years, compiling a 3.08 ERA over his past six NPB seasons. He made the NPB All-Star team in both 2021 and 2023. Uwasawa also tossed two shutouts and averaged better than seven innings per season this year.

If Uwasawa indeed finds a big league contract this offseason, any team signing him will owe a posting/release fee to the Fighters — his former club. The MLB/NPB posting system stipulates that in addition to the money paid to the player himself, his new team must pay a release fee to the former club that is equal to 20% of the contract’s first $25MM, plus 17.5% of the next $25MM, plus 15% of any money thereafter.

Naoyuki Uwasawa To Be Posted For MLB Teams This Winter

By Mark Polishuk | October 28, 2023 at 10:59pm CDT

Japanese right-hander Naoyuki Uwasawa is planning a move to North American baseball, as the Nippon Ham-Fighters starter told reporters (including the Kyodo News) at a press conference. Uwasawa isn’t yet a full agent, so he will be made available to Major League via the posting system. Uwasawa turns 30 in February, and has a 3.19 ERA over 1118 1/3 career innings with the Fighters, along with a 7.5% walk rate and a modest 19.67% strikeout rate.

Making his NPB debut in 2014, Uwasawa is a three-time All-Star (including this season) and has developed into a reliable starter in terms of both results and durability, apart from a freak injury that shortened his 2019 season. Uwasawa had his left knee fractured by a line drive that year, but has returned in good health, tossing 102 innings during the pandemic-shortened 2020 season and then throwing at least 152 innings in each of the last three full NPB seasons.

MLBTR’s Dai Takegami Podziewski has regularly featured Uwasawa in his NPB Players To Watch feature, as Uwasawa has made his intentions clear for some time that he wanted to test himself against North American competition. There are some concerns over Uwasawa’s ability to transition to the big leagues, as Dai wrote that “Uwasawa doesn’t have an overpowering arm with his average fastball velocity sitting around 90.8 mph. He also does not boast strikeout stuff, while not having the same command that [Kohei] Arihara had when he was coming to MLB (although Arihara himself was wild during his Rangers tenure).” The mention of Arihara isn’t a promising comp, as Arihara had a 7.57 ERA over 60 2/3 innings with Texas in 2021-22 before returning to Nippon Professional Baseball for the 2023 campaign.

Nonetheless, MLB teams are gauging for themselves how well they think Uwasawa might fare against big league competition. A Sports Hochi report from September indicated that scouts from the Rangers, Diamondbacks, Reds, Royals, Cubs, and Angels all saw Uwasawa in action, so the righty is drawing a fair amount of interest. While Uwasawa doesn’t have the high profile of NPB stars like Yoshinobu Yamamoto, Shota Imanaga, and others this winter, he does represent an interesting mid-level entry into the pitching market who probably won’t require a particularly large contract.

As a reminder about the MLB/NPB posting system, any players with less than nine full years of experience must first be posted by his Japanese team before negotiating with Major League clubs. Once posted, Uwasawa has 45 days to talk with any MLB team he wishes, and he would return to the Fighters after those 45 days if no contract agreement is reached. The Fighters would receive a posting fee if Uwasawa did sign with a Major League team, with the fee being worth at least 20% of the guaranteed value of Uwasawa’s contract. Should Uwasawa sign for more than $25MM in guaranteed money, the Fighters would receive a higher fee.

NPB Players To Watch: September

By Dai Takegami Podziewski | September 14, 2023 at 3:24pm CDT

The 2023 regular season is approaching its final stages in the NPB. Here’s the latest on the players we’ve been keeping track of at MLBTR. If you need a refresher on more specific player profiles, check out the first edition of the series.

Let’s get to it!

(Stats are as of September 13th)

Players likely available in the 2023 offseason (most rumored or have publicly announced desire to play in MLB)

1. Yoshinobu Yamamoto, Orix Buffaloes

Yamamoto continues to show us why he’s undoubtedly the best pitcher in NPB. The 25-year-old right-hander just tossed his second career no-hitter against the Chiba Lotte Marines this past weekend, in front of scouts/executives of 12 MLB ball clubs, including Yankees GM Brian Cashman.

It feels like a long time ago when I wrote that Yamamoto was having a “slow” start to the season by his standards, with a 2.35 ERA in his first 38 ⅓ innings. Yamamoto has shifted into a different gear since May. Yamamoto hasn’t given up an earned run in six consecutive starts, since the beginning of August. He’s currently on a 42-inning streak without an earned run allowed.

In his 20 starts in 2023, the Orix Buffaloes ace has a 1.26 ERA, striking out 26.2% of hitters and walking just 4.3%, and a 1.86 FIP in 143 frames. That 1.26 ERA is good enough for the lowest ERA in NPB since Masahiro Tanaka’s 1.27 ERA in 2011. Yamamoto is once again on pace to claim the Pacific League pitching triple crown (ERA, strikeouts, wins).

At age 25, Yamamoto is showing no signs of slowing down and continues to evolve. He notably tweaked his delivery last offseason to more of a slide-step style. Despite the “slow start”, it’s safe to say that the change has paid off, as Yamamoto has raised his average fastball velocity to 95.56 mph (152.9 km/h) compared to 94.9 mph (151.9 km/h) in 2022. In addition to his consistency, strikeout stuff, and ability to pitch deep into games, another development in Yamamoto’s game is his ability to keep the ball in the park. Yamamoto has allowed just two homers all season (he gave up between six and eight homers per season since his first full season as a starting pitcher in 2019).

2. Shota Imanaga, Yokohama DeNA Baystars

It was reported last week that the Yokohama DeNA Baystars lefty will be posted this off-season, as many in Japan predicted last off-season. The 30-year-old southpaw had his best month in July but got roughed up in August with a 5.27 ERA. He had a bounce-back outing earlier today against the Chunichi Dragons, tossing eight innings of one-run ball and striking out eleven, with the sole run coming from a solo homer. His season numbers are still strong, with a 2.71 ERA, 29.96% strikeout rate, and 3.9% walk rate in his 20 starts.

Although his ERA is not as good as 2022 (2.26), Imanaga’s strikeout rate at 29.9% is a career-best. The Baystars ace notably increased his average fastball velocity in the past few seasons. It now sits around 92.2mph (147.5 km/h), compared to 90.8 mph (145.3km/h) in 2021. While Imanaga’s arm is not overpowering, the combination of his command and strikeout stuff allows him to rack up strikeouts.

3. Yuki Matsui, Tohoku Rakuten Golden Eagles

The 27-year-old left-handed closer for the Eagles continues to be one of the best relievers in NPB. Despite his young age and being converted to a starter on a few occasions during his career, Matsui is one of the most accomplished closers in the history of NPB. The southpaw became the ninth NPB pitcher in history to reach 200 career saves and was the youngest player to ever reach that mark. On the season, he has the second most saves in NPB with 33. He’s been nothing but reliable, with strong numbers to back it up; posting a 1.55 ERA, 33.7% strikeout rate, and 5.1% walk rate in 49 appearances.

Matsui officially earned his overseas free agent rights earlier in the year, giving him the ability to sign with an MLB team without going through the posting system. The Eagles southpaw still hasn’t made clear what his plans are beyond 2023.

As I wrote in the first edition of the series, Matsui’s struggle to adapt to the WBC ball, which is closer to the MLB ball, may play a role in his MLB evaluation. If MLB offers aren’t enticing enough, he may very well choose to stay in NPB and attempt to break the NPB save record.

4. Kona Takahashi, Saitama Seibu Lions

Takahashi continues to prove that his career-best season in 2022 was not a fluke, posting a strong 2.31 ERA in 22 starts, the eighth highest among qualified starters in the entire NPB. He’s fanned hitters at an 18.8% rate and walking hitters at a 7.7% rate.

The 27-year-old righty missed a few starts in August because of an illness. He struggled in the first two starts after his return, clearly still regaining his health and conditioning. He bounced back and tossed six shutout innings this past weekend, in front of MLB scouts. He continues to make improvements and his average fastball velocity has improved dramatically since he entered the league, which should make him more intriguing to MLB teams.

Takahashi made his MLB aspirations clear last offseason, but it’s unclear if he’ll be posted by the Lions.

5. Naoyuki Uwasawa, Hokkaido Nippon Ham Fighters

Naoyuki Uwasawa has had himself another solid season for the Fighters, posting a 2.84 ERA, with an 18.1% strikeout rate and 7.7% walk rate in 158 ⅓ innings, the most innings pitched in all of NPB.

Sports Hochi reported that scouts from the Angels, Royals, Rangers, Diamondbacks, Reds, and Cubs attended his September 2nd, so MLB teams are keeping tabs on the 29-year-old right-hander. Unfortunately, there may be a Kohei Arihara-sized cloud hanging over Uwasawa’s MLB dreams. Uwasawa doesn’t have an overpowering arm with his average fastball velocity sitting around 90.8 mph. He also does not boast strikeout stuff, while not having the same command that Arihara had when he was coming to MLB (although Arihara himself was wild during his Rangers tenure).

Younger stars to keep an eye on

1. Roki Sasaki, Chiba Lotte Marines

Sasaki was on pace for a historic season rivaling Yamamoto’s, before he was diagnosed with a left oblique muscle tear which sidelined him at the end of July. The 6-foot-4 hurler was expected to miss the remainder of the 2023 regular season, but made a surprisingly quick recovery and returned over the weekend. Sasaki was limited to three innings since he skipped a rehab start, but still showcased his lively arm, with his signature fastball sitting between 98mph and 100mph. The Marines will likely not overextend their star right-hander, so he will be carefully managed for the remainder of the season.

On the season, Sasaki has a 1.53 ERA, an unbelievable 40% strikeout rate, a 4.8% walk rate and 88 innings in his 14 starts. There is no doubt about Sasaki’s talent and natural frame at 6’4″ and 203 pounds. The only thing Sasaki has left to “prove” is his durability, and showcasing that he can pitch multiple full seasons. There is plenty of time for him to prove that, since he’ll likely be posted in the 2026 offseason at the earliest, barring any surprise requests.

2. Munetaka Murakami, Tokyo Yakult Swallows

Murakami has shrugged off most concerns and has re-established himself as one of the premier power hitters in NPB. Although he has had, by his standards, the statistically worst season since his rookie season in 2019, Murakami is still slashing a solid .253/.372/.497 with 28 homers, 77 RBIs, and a .869 OPS.

Murakami did address his early season slump in an August interview, where he said he lost his way a little bit while training with the other Japanese stars in the lead-up to the WBC. He said that he got distracted trying to incorporate the training regimen of players like Shohei Ohtani, Masataka Yoshida, and Yu Darvish and did not address his swing as much as he should have.

While he does have a great walk rate at 18.1%, Murakami is still striking out at an alarming 34.5% rate. He also struggles to hit righties, hitting just .209 against them. He still needs to make improvements with his defense at third base, as he has an NPB-worst 20 errors. This season is obviously far from Murakami’s best, but a down year may allow him to come back even stronger next season.

Murakami signed a three-year deal last offseason that came with a reported guarantee that he will be posted in the 2025-2026 offseason.

3. Kazuma Okamoto, Yomiuri Giants

Okamoto’s name came up in headlines last week, after it was reported that he was on the radar of several MLB teams. Okamoto is in the midst of a career-year, with a slash line of .293/.386/.611 with 90 RBIs and an NPB-leading 38 homers and .997 OPS. He has an 18.9% strikeout rate and a 12.2% walk rate. He was unstoppable in August, slashing .318/.422/.812, blasting 12 homers and driving in 25 runs.

Okamoto has hinted at interest in a potential MLB move, but he isn’t set to be a free agent until the 2026-2027 offseason. The 6’1″, 220-pound slugger is a career .275 hitter with 182 homers, hitting at least 30 homers in every season since becoming a full-time starter in 2018. The Giants slugger has hit 30 homers for six consecutive seasons, which speaks to his durability and consistency.

The Giants are traditionally against the posting system. The only two players they allowed to be posted were Shun Yamaguchi and Tomoyuki Sugano, and both were unique situations. Yamaguchi was given permission because he made it a part of his free agency deal when signing for the Giants from the Baystars in 2016. Sugano was given special permission to enter the posting system, because he refused to join the Nippon Ham Fighters when he was originally drafted in 2011 and he held out for an entire season before being drafted by the Giants in 2012 (and his uncle is Giants manager Tatsunori Hara, which may have played a role).

As expected, the ball club has denied any conversations regarding Okamoto’s potential move, with executive Atsunori Otsuka saying “We’ve heard he has MLB aspirations, but we’ve never had direct discussion with him about that. We typically don’t accept posting, and want our players to earn their overseas rights. It was the same with Hideki Matsui.”

Honorable Mentions

The following players have either expressed their desire to play in the big leagues, been rumored by Japanese media, or have drawn interest from MLB scouts but have factors (age, team stance on posting system) preventing a potential move. Other NPB top performers are also on the list.

Shosei Togo, right-handed starting pitcher, Yomiuri Giants; Taisei Ohta, right-handed reliever, Yomiuri Giants; Hiroto Takahashi, right-handed starting pitcher, Chunichi Dragons; Kaima Taira, right-handed starting pitcher, Saitama Seibu Lions; Atsuki Yuasa, right-handed reliever, Hanshin Tigers; Shinnosuke Ogasawara, left-handed starting pitcher, Chunichi Dragons; Shunpeita Yamashita, Orix Buffaloes; Atsuki Taneichi, right-handed starter, Chiba Lotte Marines. Liván Moinelo, left-handed reliever, Fukuoka Softbank Hawks. Raidel Martinez, right-handed reliever, Chunichi Dragons. (Moinelo and Martinez will have to defect their homeland, Cuba, to join MLB)

NPB Players To Watch: July

By Dai Takegami Podziewski | July 21, 2023 at 6:53pm CDT

The NPB All-Star Game wrapped up this week and the second half of the 2023 season is set to start back up tomorrow. Let’s catch up with the NPB stars who may be making their way to MLB.

For more detailed profiles and playstyles, please take a look at the first post of the series from April!

Players likely available in the 2023 offseason (most rumored or have publicly announced desire to play in MLB)

1. Yoshinobu Yamamoto, Orix Buffaloes

In the last update, I wrote that Yamamoto had his best month of the season. The 24-year-old right-hander has maintained his excellent form through June and through the All-Star break. Outside of a June 23 start against the Fukuoka Softbank Hawks where he gave up four runs in six innings, he’s tossed at least eight innings of one-run ball in each of his last three starts, including a complete game against the Saitama Seibu Lions on July 8.

On the season, Yamamoto has a 1.74 ERA, a solid 28.7 K%, and an impressive 3.3 BB% in 13 starts and 93 ⅓ innings pitched. He’s fourth in the Pacific League in innings despite having three fewer starts than the league leader. He’s issued just one walk in his past four starts, and hitters have a .201 batting average against him. He was a surprise and controversial snub from the initial All-Star ballot, but was eventually voted in through the “Plus One” runoff voting to earn his fifth consecutive All-Star nod.

MLB teams are ramping up their interest in Yamamoto, with scouts of eight teams attending his July 8th start, per Sports Hochi. He also ranks second in MLBTR’s recent 2023 free agency power rankings, and as Steve Adams writes, “A contract in excess of $200MM doesn’t seem outlandish if he can remain healthy and productive.”

2. Shota Imanaga, Yokohama DeNA Baystars

The 29-year-old left-hander has been at his very best since the last update, allowing just three runs in 32 innings in his last four starts — including a one-run, complete game against the Hanshin Tigers on June 23 and a seven-inning, 15-strikeout gem against the Yomiuri Giants on July 7. He finished June with a 1.41 ERA and has a 0.60 ERA thus far in July.

Imanaga’s ERA is down to 2.07, which is fourth among qualified pitchers in the Central League, with a 28.5 K% and a minuscule 2.4 BB% in 12 starts and 87 innings pitched. These stats were good enough for the lefty to get to his second career All-Star nod. Although he is still prone to long balls with 11 homers allowed on the season, he’s otherwise avoided trouble. Imanaga’s chances of coming to MLB are pretty high, as he signed with the U.S.-based agency Octagon to help talks toward a posting agreement last offseason.

3. Yuki Matsui, Tohoku Rakuten Golden Eagles

The 27-year-old left-hander finished the first half with 23 saves, tied for most in NPB. He’s yet to give up a run in eight appearances in July and has been key to the Eagles going 11-3 in the month. The increased workload is a big contrast from NPB updates earlier in the season where Matsui didn’t have as many appearances due to the Eagles’ poor record.

Matsui has a 0.55 ERA in 34 appearances, with a 36.3 K% and a 4.1 BB%. Although he was snubbed from the All-Star Game, Matsui is happy with the rest. “I’m thankful [for the increased workload], it’s my job to close out games and win so it’s a good thing,” Matsui said. Matsui has still not made his plans beyond 2023 clear, but he is definitely a name to keep an eye on for teams that need a lefty for their bullpen.

4. Kona Takahashi, Saitama Seibu Lions

Takahashi has had a rough July on paper, recording a 3.79 ERA in three starts, including two outings lasting just five innings. He’s bounced back from those outings in his most recent start on July 16, tossing a four-hit, six-strikeout, complete game shutout against the Hokkaido Nippon Ham Fighters. It was his first shutout since 2020 and the fourth of his career.

The 26-year-old right-hander’s ERA now sits at 2.25 despite the rough starts in the past few months, with a 19.1 K% and a 6.8 BB% in 16 starts and 108 innings pitched. Takahashi also missed out on the All-Star game despite his strong performance in the first half thanks to a deep pool of quality starters in the Pacific League.

Takahashi’s strikeout rate has dropped in the past few weeks, but increased average fastball velocity and ability to eat innings should still be appealing to MLB teams looking for some starting pitching help.

5. Naoyuki Uwasawa, Hokkaido Nippon Ham Fighters

In the last update, I wrote that Uwasawa was back to his best, and finishing the season closer to a 2.50 ERA would help his chances for an MLB contract this offseason. The 29-year-old right-hander followed up his strong June with solid performances in July, including eight shutout innings against the Lions this past weekend.

His season ERA is down to 2.87 with a 17.3 K% and 7.4 BB%. If you remove his worst start of the season against the Lions on April 15 (where he gave up eight earned runs in 5 ⅓ innings), his ERA goes all the way down to 2.31. It’s quite a remarkable turnaround for Uwasawa considering that his ERA was up to 4.62 on May 6. He is third in the Pacific League with 106 ⅔ innings in 15 starts. Uwasawa received his second career All-Star nod, his first since 2021.

Younger stars to keep an eye on

1. Roki Sasaki, Chiba Lotte Marines

In his last three starts since the last update, Sasaki has allowed just one run in 22 frames while going at least seven innings and fanning at least 10 in every one of those starts. He also matched the record for the fastest NPB pitch at 103 MPH. In his most recent start, where he struck out 14 in seven innings, the average velocity on his fastball was at 99 MPH. There aren’t enough words to describe Sasaki’s dominance in the first half of 2023, as he finished with an NPB-best 1.48 ERA in 12 starts. He had an unfathomable 41 K%, 4.7 BB%, and a.151 opponent batting average in 79 innings pitched. It’s hard to imagine Sasaki can improve on these numbers, but with the combination of his age at 21 and 2023 being just his second full season of work, it’s certainly possible he reaches another level. Sasaki still has room to improve his in-game stamina and has some remaining physical projection.

2. Munetaka Murakami, Tokyo Yakult Swallows

Murakami continues to look more like his Triple Crown-winning self, following up a strong June with a few solid weeks to finish up the first half of the season. He’s slashing .306/.352/.612 with four homers in July. Murakami finished the first half of the season slashing .242/.359/.451 with 16 homers and his OPS is finally above .800 at .809. Despite his horrendous slump to open the season, Murakami still finished the first half in the top three in homers and RBI in the Central League. He’s managed to regain some of his form even though the Swallows are missing key lineup contributors with injuries: including perennial All-Star Tetsuto Yamada and Yasutaka Shiomi, who has been a .800 OPS hitter since 2020. Murakami is still striking out at an alarming 31% rate and has a strong 14.2 BB%. Murakami missed out on the All-Star Game,

3. Kazuma Okamoto, Yomiuri Giants

Although the 27-year-old corner infielder is slashing a .297/.393/.557 with a .950 OPS, 20 homers, and 51 RBIs (all in the three in all categories in the Central League), Okamoto has cooled off significantly in July, slashing just .208/.328/.375. The All-Star break could not have come at a better time for Okamoto, who had just two hits out of 26 plate appearances in his last six games to close the first half. He was the first to reach the 20-homer mark in NPB on July 7, on a solo homer off of Imanaga, but hasn’t added to his tally since. Despite the mini-slump, Okamoto is still on pace for what would be his sixth consecutive 30-homer season.

An interesting note is that he has been mashing lefties this season, slashing .355/.463/.656 in 110 plate appearances. If he is able to continue to mash lefties, the combination of Okamoto’s consistent power numbers, solid defense at the corners (two-time Gold Glove winner), and potential for positional versatility (taking reps at left field this year) should be a compelling package for MLB teams looking to add a right-handed power bat.

NPB Players To Watch: June

By Dai Takegami Podziewski | June 21, 2023 at 4:14pm CDT

It’s time for an update on NPB players who may be making their way to MLB in the near future. Here are the eight players that we are keeping track of at MLBTR. More details about their play styles and background are in the first article.

Players likely available in the 2023 offseason (most rumored or have publicly announced desire to play in MLB)

1. Yoshinobu Yamamoto, Orix Buffaloes

In the May update, I wrote that Yamamoto had yet to have his signature outing of the 2023 season, and since then he’s posted three consecutive gems. Yamamoto tossed eight innings in all three starts, allowing just one run and holding hitters to .092, while fanning 29.8% of them.

The 24-year-old right-hander now has a 1.59 ERA on the season, striking out 28.3% of hitters while walking just 4.6% and holding hitters to .188 in 62 ⅓ innings.

Yamamoto faces stiff competition from Sasaki for most strikeouts, but a third consecutive Pacific League Triple Crown (ERA, Wins, Ks) is definitely within reach.

2. Shota Imanaga, Yokohama DeNA Baystars

The 29-year-old left-hander is back to looking like the Yokohama Baystars ace after a rough May. In his last four starts, Imanaga has a 2.32 ERA, striking out 23.3% of hitters and walking 4.3%.

On the season, Imanaga has a 2.78 ERA, 26.7 K%, 3.3 BB%, and keeping hitters to a .225 batting average in 55 innings. The lefty struggles with the long ball at times (giving up eight in May), but regularly pitches deep into games, only failing to throw seven innings twice.

Imanaga positioned himself for an MLB move in 2023 by signing with a new agency last December. Given his strong track record in both NPB and international competitions, multiple teams should be showing interest in Imanaga this offseason.

3. Kona Takahashi, Saitama Seibu Lions

After a blistering start to the season, Takahashi has hit somewhat of a rough patch, with a 3.46 ERA in his last four starts. The 26-year-old right-hander is still tied for the Pacific League lead in ERA among qualified pitchers with a 2.11 mark.

On the season, the Lions’ ace is striking out 21% of hitters and holding them to .215, while walking 7.3% in 81 total innings.

According to Nikkan Gendai, an MLB scout said that Takahashi’s improvement has been a pleasant surprise. “He did not know how to pace himself before, so he’d be tired by around 80 pitches. Since last season, he’s balanced out his delivery and pace. With his frame at 6’2-6’3 and 231 lbs and the combination of an upper 90s fastball and splitter, barring any setbacks, multiple MLB teams should show interest in the offseason.”

4. Yuki Matsui, Tohoku Rakuten Golden Eagles

The 27-year-old left-handed closer is as reliable as ever, with a 0.77 ERA, 38.8 K%, and 14 saves in 24 appearances in 2023.

An overseas free agent this offseason, Matsui has not clearly stated his intentions for a move to MLB this offseason outside of vague comments made earlier in his career.

Interestingly, he has made some changes this season that may be signaling a potential move.

He has mostly relied on his four-seam, splitter, and slider in his career, but this season he has cut down his slider usage and heavily increased the usage of his splitter. Given that the ability to throw splitters is highly valued in MLB, this could very well be him showcasing MLB front offices that his stuff will translate to the big leagues.

There is certainly a need across the league for left-handed relievers with strikeout ability, and Matsui may be an interesting option.

5. Naoyuki Uwasawa, Hokkaido Nippon Ham Fighters

The 29-year-old right-hander has bounced back from a nightmarish start to the season and is back to looking like an ace for the Fighters. In his last four starts since the previous NPB update, Uwasawa has a 1.74 ERA in 31 innings, striking out 20.8% of hitters and holding them to a .158 batting average, while walking 6.7%.

Stuff-wise, Uwasawa lags behind the other players on the list and profiles similar to former Fighters teammate and former Rangers starting pitcher Kohei Arihara. He faces an uphill battle to earn an MLB contract, but he seems intent on taking on the challenge anyway. Maintaining his current form and finishing the season below a 2.50 ERA would definitely improve his chances.

Younger stars to keep an eye on

1. Roki Sasaki, Chiba Lotte Marines

Sasaki has come down to earth a little bit after a 1.00 ERA in April and 1.64 ERA in May. In his last four starts, Sasaki has a 3.24 ERA and two losses. The ‘Monster of Reiwa’ still has a 1.89 ERA on the season, striking out hitters at an unfathomable 40.4% rate and holding them to .146 while walking just 5.6%.

While Sasaki has unquestionable stuff and strikeout ability, building up the stamina to handle a full season workload is the next step in his development. Marines manager Masato Yoshii said that he might skip Sasaki’s next start, saying that he looked tired. Sasaki usually throws on six days of rest this season. Unless he makes a surprise request to be posted, Sasaki has a couple of season to improve that area of his game.

2. Munetaka Murakami, Tokyo Yakult Swallows

The reigning Triple Crown winner looks more like himself in June, slashing .291/.418/.455 in 67 plate appearances. On the season, Murakami has a .233/.317/.419 line with a .789 OPS and 11 homers, a disappointing follow-up to his historic 2022 season.

Murakami is striking out on a horrendous 32% of at-bats, and his NPB-worst 89 total strikeouts is 22 more than the next closest at 67 strikeouts. He still has a strong walk rate at 16.5%, but is simply not making good contact.

Murakami is especially struggling to hit velocity, hitting just .083 against fastballs thrown harder than 150 km/h (93.75 mph). and is also struggling to hit righties, hitting just .180.

3. Kazuma Okamoto, Yomiuri Giants

A newcomer on this list, Okamoto has been one of the best hitters in NPB who is enjoying a career season. Some of you may remember him for his solo homer that extended Team Japan’s lead over Team USA in the WBC Final.

The 6’1, 220lb slugger is a career .275 hitter with 182 homers, hitting at least 30 homers in every season since becoming a full-time starter in 2018. Okamoto was the youngest player in NPB to post a .300, 30HR, 100 RBI season. He led the Central League in homers and RBIs in back-to-back seasons in 2020 and 2021,

The soon-to-be 27-year-old corner infielder is hitting .322/.414/.597 with 17 homers, 42 RBIs and an OPS of 1.010 in 2o23. He would be in prime position for the Triple Crown in any other season if it wasn’t for Toshiro Miyazaki and his .372 batting average.

In comparison to Murakami, Okamoto hits for less average and walks less. Okamoto has hit over .300 just once in his career, and has a 10.5% career BB% compared to Murakami’s 16.5%. Okamoto plays average defense at third base and has taken first base and left field reps this year.

Okamoto has hinted at some interest in a potential MLB move, but there is nothing concrete yet. He isn’t set to be a free agent for four years, his age-31 season. The Giants are traditionally against the posting system, so it remains to be seen whether or not he will request a move before that.

NPB Watch: May Edition

By Dai Takegami Podziewski | May 23, 2023 at 3:37pm CDT

It’s time for an update on NPB players who may be making their way to MLB in the near future. Here are the seven players that we are keeping track of at MLBTR. Learn more about their play styles and background in the previous article.

Let’s get started.

Players likely available in the 2023 offseason (most rumored or have publicly announced desire to play in MLB)

1. Yoshinobu Yamamoto, Orix Buffaloes

The two-time Pacific League MVP has had a “slow” start to the season by his standards. Yamamoto has been consistent and his numbers are as solid as ever, with a 2.35 ERA, 27.6 K%, 6.4 BB%, 2.15 FIP in 38 ⅓ innings, but he’s yet to have the signature performance of the season.

For reference, the Buffaloes ace’s best month last season was June, with a 0.56 ERA in four starts, most notably tossing his first career no-hitter.

Yamamoto was scratched from his planned start this past weekend due to illness but has not been limited by injury thus far, despite concerns.

2. Shota Imanaga, Yokohama DeNA Baystars

In five starts, Imanaga has a 3.48 ERA, 28.4 K%, and 1.6 BB% in 31 innings. The Baystars ace was off to a hot start to the season, tossing 8 innings of shutout ball in his season debut and following it up with a 7-inning shutout performance where he struck out 12. He’s struggled in the following two starts, however, giving up four runs in five innings and five runs in four innings respectively, and allowing a total of four homers.

In his most recent start this past weekend, Imanaga had a solid performance against the Tokyo Yakult Swallows, allowing three runs in seven innings. The three runs came from two home runs, however, so the long ball continues to be an issue for the left-hander in the early going.

Imanaga officially earned his domestic free-agent rights on May 19, but remains focused on the season. “I never thought I’d be in this position to earn this [free agency], and I want to give back to everyone who has been a part of my journey,’ Imanaga said.

3. Kona Takahashi, Saitama Seibu Lions

Takahashi has had an impressive start to the year. In his eight starts, the Lions ace has an NPB-best 1.47 ERA, holding hitters to a .182 average, striking out 22.9% of hitters and walking 13.6%, in 55 innings. The biggest factor in his improvement is increased average fastball velocity, which has gone up to 94 mph, compared to 91.56 mph last season. His splitter has been the perfect complement to his improved fastball, hitters are only .068 against it.

Beyond his elite numbers, Takahashi’s strong mentality and his pride as the Lions’ ace have particularly stood out. After his most recent start where he tossed six innings of shutout ball, Takahashi said, “I wanted to be on the mound longer than the opposing pitcher. In order to continue improving, I will reflect on this start so that I can go even deeper into games.”

He outdueled Yamamoto in their April 22 matchup, holding the Buffaloes to two runs and five hits in a complete game. He almost outdueled Yamamoto again on May 6, exiting the game after six innings of one-run ball, but the bullpen was unable to keep the lead.

Takahashi has certainly met the challenge from GM Watanabe and Manager Kazuo Matsui thus far

4. Yuki Matsui, Tohoku Rakuten Golden Eagles

Became the fastest pitcher in NPB to reach 200 career saves earlier in the season. The Golden Eagles closer has been dominant as ever and has not allowed an earned run in his 12 appearances. He has 6 saves on the season, and hitters are hitting just .095 against him. The lefty hasn’t gotten much work as other relievers so far, as the Eagles have the second-worst record in NPB and sit in last place in the Pacific League.

Matsui officially earned his overseas Free Agent rights on April 27. “It’s still April, so there’s not much to think about,” Matsui said in a statement.

5. Naoyuki Uwasawa, Hokkaido Nippon Ham Fighters

After a nightmarish start to the season, Uwasawa has settled down and is finding his groove. In his last four starts, he’s completed at least 7 innings and has a 2.35 ERA in 30 ⅔ innings. The Fighters right-hander has a 3.72 ERA on the season, striking out 17.9% of hitters and walking 10.8% in 46 innings.

In his most recent start, the 29-year-old right-hander tossed his first shutout since 2018 against the Saitama Seibu Lions, where he fanned 9 and allowed just 4 hits.

Younger stars to keep an eye on

1. Roki Sasaki, Chiba Lotte Marines

The “Monster of Reiwa” is off to a dominant start, posting a 0.84 ERA, fanning 43.5% of hitters while walking just 4.3%. Hitters are only hitting .124 against him, and he has a FIP of 0.65.

He’s been sidelined since his May 5 start where he exited in the 5th inning because of a blister on the middle finger of his throwing hand. He was initially scheduled to pitch on May 21 but was pushed back to May 28, after the starting rotation was reshuffled by a rain-out.

2. Munetaka Murakami, Tokyo Yakult Swallows

The young Swallows slugger had a disastrous first month of the season. In 25 games, he hit .157/.311/.265, 2 HR, 15.5 BB%, 37.9 K%, and 12 RBI in 103 plate appearances. Murakami-sama is beginning to look more like his Triple-Crown winning self in May, hitting .278/.381/.556, 4 HR, 14.3 BB%, 23.8 K%, and 10 RBI in 63 plate appearances (as of May 19).

One of the major factors in Murakami’s early season slump is his struggle to hit right-handed pitching. Murakami is hitting a measly .169 against right-handed pitching, and striking out at a 37.7% rate. The slump is also affecting his already sub-par defense at third base where he has 8 errors, the most out of all position players in NPB.

NPB To MLB: 7 Players To Watch

By Dai Takegami Podziewski | April 21, 2023 at 11:15am CDT

A new wave of NPB players have chosen to pursue their big-league dreams in recent years. Just this past offseason, Kodai Senga signed a five-year, $75MM deal with the Mets, Masataka Yoshida signed a five-year, $90MM deal with the Red Sox, and Shintaro Fujinami signed a one-year, $3.25MM deal with the Athletics. One offseason prior, Seiya Suzuki signed a five-year, $85MM deal.

Making the move from NPB to MLB is a complicated process. A player needs to have nine seasons of experience on the first team (i.e. the NPB “major league” club, as opposed to their minor league team) before they can become an overseas free agent. At the earliest, a player drafted out of high school becomes a free agent at age 27 and a player drafted out of college becomes one at age 31. This is a long period of time and can take even longer if a player misses time due to injury. Players who want to make the move sooner instead opt to use the NPB-MLB posting system. The posting system grants all 30 MLB teams the right to negotiate with a player after posting, but the team is subject to paying a posting fee based on the amount of guaranteed money in the contract.

The two main difficulties with the posting system are that 1.) players need their team’s permission to be posted, and 2.) players need to wait several years before being classified as “professionals” rather than “amateurs” under Major League Baseball’s international free agency standards. In order to be considered a “professional” and thus be exempt from MLB’s hard-capped bonus pool system for international amateurs, a foreign-born player must be at least 25 years of age and have at least six years of experience in a professional league (NPB, in this case). Shohei Ohtani knew this and chose to pursue a jump to MLB at age 23 anyway, limiting himself to a signing bonus a little north of $2.3MM because his age made him an “amateur.” Had he waited two more years, Ohtani could have potentially commanded 100 times that sum as a “professional” under MLB’s classifications. It was a sizable bet on himself, but it looks like one that will pay off.

Some teams are traditionally open-minded about letting players pursue their MLB dreams, most notably the Nippon Ham Fighters, while other teams such as the Yomiuri Giants and the Fukuoka Softbank Hawks have traditionally not given permission to their players when they ask to be posted for MLB clubs.

This series will keep track of NPB players who may be making their way to the MLB in the near future.

Let’s get started with players who may be available in the 2023 offseason.

Players likely available in the 2023 offseason (most rumored or have publicly announced desire to play in MLB)

1. Yoshinobu Yamamoto

Yoshinobu Yamamoto is a 24-year-old right-hander for the reigning Pacific League and Nippon Series champions Orix Buffaloes. He began his career as a starter but moved to the bullpen in 2018 and became one of the best relievers in NPB. He was moved back to the rotation in 2019 and established himself as an elite starter by leading the Pacific League with a 1.95 ERA.

Yamamoto has since become the undisputed ace of NPB. He’s won the Sawamura Award — the Japanese equivalent of the Cy Young Award — and the Pacific League MVP Award in back-to-back seasons. He posted an insane 1.39 ERA, 206 strikeouts, 28% strikeout rate, and 5.4 walk rate in 2021, and followed that up with a 1.68 ERA, 205 strikeouts, a 27.4 strikeout rate, and a 5.6 walk rate in 2022. Yamamoto also won the Gold Glove award in each of those seasons. MLBTR’s Steve Adams wrote more on Yamamoto back in Februrary. Some scouts believe that Yamamoto is ahead of Senga.

The Pacific League MVP relies on a deep six-pitch repertoire and elite control to pile up strikeouts. Yamamoto primarily leans on his mid-90s fastball, splitter, and curveball, but he occasionally mixes in a cutter, two-seamer, and slider. The right-hander is known for his unique training style, with a focus on flexibility and mobility as well as using javelin-like and hammer-like tools. He also has a personal chef/nutritionist to manage his diet. While he has not had a major injury so far in his career, the only concerns with the Buffaloes ace are his slight frame (5’10″, 175 pounds) and adjusting to the grueling MLB schedule. Although he has not thrown on a four-day rest schedule, he has showcased his durability by throwing over 190 innings in each of the past two seasons.

As MLBTR’s Tim Dierkes wrote in his recent 2023 FA class power rankings, Yamamoto’s contract could exceed Masahiro Tanaka’s contract with the Yankees in 2014. Tim wrote: “Ten years after the Tanaka deal, I feel Yamamoto is indeed capable of reaching $200MM before accounting for a posting fee.”

Yamamoto is off to another fantastic start this season. In the two games he’s started so far, he has a 0.75 ERA and 15 strikeouts in 12 innings of work.

2. Yuki Matsui

Yuki Matsui is a 27-year-old left-handed reliever for the Tohoku Rakuten Eagles. He has a career 2.46 ERA, 31.9% strikeout rate, 201 saves, and 68 holds in 447 appearances. Matsui has a four-pitch arsenal featuring a four-seam fastball that goes up to 96mph but averages between 92-94, a dominant splitter and slider, and a lesser-used curveball.

Matsui is on track to become a true international free agent this offseason, so he won’t need to utilize the posting system to gauge interest from MLB clubs. Japanese media is already speculating that he may sign with an MLB team. Matsui has said he is focused on the upcoming season but is open to the move. Sports Hochi reported that Matsui and the Eagles have discussed future MLB plans during contract negotiations over the years.

Matsui first hit the national spotlight as a high school player at the 2012 Summer Koshien Tournament, the Japanese equivalent of March Madness, where he set the tournament record for most strikeouts in a single game with 22, and the longest consecutive strikeouts with 10. He finished that tournament with the most strikeouts in a single tournament by a lefty with 68.

Matsui came into the league as a starter but was moved to the bullpen in 2015 and since then has consistently been one of the best closers in the NPB. Out of the seven seasons he was the primary closer, Matsui recorded over 30 saves in five of them. His only “down” year came in 2018 — he still posted a 3.34 that season — but he bounced back with a career-high 68 appearances and 38 saves in 2019. He was moved to a starting role in 2020, before ultimately moving back to the bullpen at the end of the season where he has remained until now. Matsui struggled adjusting to the WBC ball, which is closer to the MLB ball, so that may be a concern moving forward.

Despite his difficulties at the WBC, Matsui had a terrific start to the season. He’s thrown five shutout innings, recorded four saves and fanned eight of his 18 opponents (44.4%). Dating back to 2021, Matsui has a 1.26 ERA in 99 2/3 innings of relief work.

3. Shota Imanaga

Shota Imanaga is a 29-year-old left-handed starting pitcher for the Yokohama DeNa Baystars. Fans might recognize Imanaga’s name after his start for Team Japan in the World Baseball Classic final against Team USA. The left-hander has a 3.24 ERA, 24.3 strikeout rate, 7.3 walk rate and 854 2/3 innings in 136 career starts. He had a career year last season, posting a 2.26 ERA, 23.6 strikeout rate and 5.2 walk rate in 143 2/3 innings. He also recorded his first no-hitter in June.

The Baystars ace primarily throws four pitches, including a 91-94 mph fastball, a changeup that is close to a split-change, a cutter, and a curveball, while occasionally mixing in a slider. While he does not have an overpowering fastball, he has elite command and uses his changeup to get strikeouts. He had shoulder surgery in 2020 but has made a full recovery, and shoulder trouble hasn’t been a recurring issue for him.

Imanaga has expressed his desire to pitch in the big leagues since 2021 but won’t be an overseas free agent until the 2025 season. Sponichi reported in December that Imanaga planned to sign with the U.S.-based agency Octagon to help talks toward a posting agreement. The Baystars have never posted a player before, so it is unclear if they are open to posting Imanaga. However, Imanaga is set to become a domestic free agent within NPB this offseason, so if the Baystars do not allow Imanaga to go to the big leagues, he could potentially move to another NPB team.

Imanaga is yet to pitch for the first team this season as the Baystars manage his workload after pitching for Team Japan. He’s completed his minor league starts with no complications and is set to make his regular-season debut with the first team soon.

4. Kona Takahashi

Kona Takahashi is a 26-year-old right-handed starter for the Saitama Seibu Lions who had his career-best season last year. In his 26 starts, Takahashi recorded a 2.20 ERA and struck out 18.2% of hitters faced in 175 2/3 innings. He was wilder earlier in his career, walking more than 12% of his opponents, but has improved his command more recently. Takahashi has a career 3.55 ERA, 17.4% strikeout rate, and 9% walk rate in 133 starts. He primarily relies on four pitches: a fastball that sits at around 93-95mph, a splitter, a slider, and a cutter, while occasionally throwing a curveball.

Takahashi called MLB “the world’s greatest peak” and said he was inspired by former teammate and now Toronto Blue Jays pitcher Yusei Kikuchi. “Yusei-san changed my baseball career. I want to give back to him by performing at the highest level and even surpassing him,” Takahashi said. He attended Game 4 of the 2022 World Series in Philadelphia and said “The atmosphere was amazing and I thought that I’d love to pitch here [in MLB].”

Despite Takahashi’s wishes, the Lions may not post him this offseason. Lions GM Hisanobu Watanabe said that there are no plans as of right now to post Takahashi. “We’ve just listened to his [Takahashi’s] wishes at this point. We’ve discussed things of that nature with him before, but it’s not a story of when we are going to post him,” Watanabe said. The right-hander wants to be posted in the near future since the earliest he can earn his overseas free-agent rights is 2026. The good news for Takahashi is that his manager is former New York Met Kazuo Matsui, who is open-minded about the possible move. “If he reaches another level as an ace, he might get closer to that goal,” Matsui said.

Takahashi is doing his best to reach that next level, with a 0.39 ERA, 27.4% strikeout rate and 23 innings pitched in his three starts. He has not given up a run in 18 consecutive innings.

5. Naoyuki Uwasawa

Naoyuki Uwasawa is a 29-year-old right-handed starter for the Nippon Ham Fighters who has a 3.29 ERA, 19.9% strikeout rate, and 8% walk rate in 148 career starts. The right-hander throws a variety of pitches, including a low-90s fastball, cutter, slider, splitter, knuckle curve, changeup, and a two-seam fastball (usage in that order). His four-seam fastball was hit hard last season, with opponents batting .272 against it.

Uwasawa announced his desire to pitch in the majors at his contract negotiations last December and requested to be posted in the 2023 offseason. He said that he was inspired when he participated in the 2018 MLB Japan All-Star Series. “I’ve always wondered what it’s like to play in a league with players coming from around the globe, and it’s the type of experience I can’t miss if I have the chance to. I only have a limited amount of time to take on the challenge, so if I have the opportunity I would take it,” Uwasawa said. Uwasawa began working with Driveline last offseason to help prepare his transition to the big leagues, looking to optimize his pitching mechanics and improve the quality of his slider.

Uwasawa has had a poor start to the season, with a 6.46 ERA and 16.9% walk rate through 15 1/3 innings in his three starts.

Younger stars to keep an eye on

The following players are already some of the biggest stars in the NPB, but are likely unavailable until the 2025-26 offseason due to their age.

1. Munetaka Murakami

Munetaka Murakami, nicknamed Mura-Kamisama (Mura-God), is a 23-year-old corner infielder for the Tokyo Yakult Swallows. He burst onto the scene in 2019, with 36 home runs and 96 RBIs, winning the Central League Rookie of the Year Award in the process. He was the back-to-back Central League MVP in 2021 and 2022. Murakami has a career slash line of .281/.405/.583, hitting 160 homers and driving in 430 runs, along with a .988 OPS and 166 wRC+. Murakami’s 2022 season was nothing short of historic. He batted .318/.458/.710 with 56 home runs and 134 RBIs, along with a jaw-dropping 1.168 OPS, 221 wRC+ and 10.3 WAR. He became the youngest-ever Triple Crown winner in NPB and set the single season record for home runs hit by a Japanese player.

Murakami’s leap in 2022 can likely be attributed to overcoming hard-thrown fastballs. Hitting high velocities was a weakness early in his career, with batting averages of .088 in 2019, .167 in 2020, and .229 in 2021 against fastballs thrown over 150 km/h (93.75 mph). In 2022, Murakami hit .327 against those pitches. Consistent growth in this area will be essential to Murakami’s success in MLB, where the average velocity is higher than the NPB. Murakami is not necessarily known for his defense at third base. In 2022, he recorded 15 errors, the second-highest in all of NPB and the most among third basemen. If he cannot improve his defense as he did with his contact against higher velocity, he most likely projects to be a first baseman in MLB.

Murakami signed a three-year deal this past offseason that came with a guarantee that he will be posted in the 2025-26 offseason. By 2025, Murakami will be 25 years old and shed his “amateur” status under MLB rules, thus exempting him from the bonus pool system. There is a clause that will allow him to get posted sooner if the age-25 rule is lowered.

Murakami has had a slow start to the season, hitting just .189/.328/.373 with two homers and a 33.3% strikeout rate in a small sample of 66 plate appearances. The good news is that he is walking in 18.2% of plate appearances, and hitting .375 with runners in scoring position.

2. Roki Sasaki

Roki Sasaki is a 21-year-old right-handed starter for the Chiba Lotte Marines, known as “The Monster of Reiwa”, who is entering his fourth season in NPB. Sasaki has been highly scouted since his high school days, throwing 100mph fastballs with ease. He was drafted in 2019 by the Marines, who took a patient approach to his development. The 6’3″ right-hander clearly had an outstanding arsenal, but teams were concerned about his thin frame, in-game stamina, and the repeatability of his mechanics. He did not pitch in 2020 and only started in 11 games and pitched 63 1/3 innings in 2021.

The Marines’ patience paid off, with Sasaki quickly becoming one of the most dominant starters in NPB. In his first full year in the Marines’ rotation, the phenom recorded a 2.20 ERA and 1.70 FIP, striking out 35.3% of hitters while walking just 4.7% in 129 1/3 innings. Sasaki became the 16th pitcher in the history of NPB to pitch a perfect game last April, and followed up the performance by throwing eight more perfect innings in his next outing, before getting pulled with 102 pitches. In the 17 perfect innings, Sasaki struck out 33 of the 51 batters faced. Sasaki has a three-pitch mix, a fastball that averages between 99-101mph and tops out at 104mph, a devastating splitter, and a slider.

As of right now, there is no clear timetable for Sasaki’s jump to Major League Baseball. Sasaki will not hit the professional experience threshold and does not turn 25 years old until 2026, so unless he takes the Ohtani route of posting before age 25, the earliest that Sasaki will make his MLB debut is in 2027. Sasaki said in March that “Before thinking about the timing of moving to the majors, playing in Japan comes first, and I think that things will become more clear after that.”

Sasaki has picked up right where he left off last season and has yet to allow a run in his two starts. Last week, he outdueled Yamamoto and shut down the Buffaloes, only allowing one hit and striking out 11 in seven innings.
