NPB’s Kazuma Okamoto, Tatsuya Imai Expected To Be Posted For MLB Teams

By | at

7:34pm: Jon Heyman of The New York Post writes that Okamoto and Imai are indeed both expected to be posted this offseason.

12:24pm: Every offseason, a handful of high-profile players from Japan’s Nippon Professional Baseball and the Korea Baseball Organization in South Korea either reach true free agency or are made available to MLB teams by way of the posting system. We already know that slugging third baseman Munetaka Murakami (NPB’s Yakult Swallows) and steady right-hander Kona Takahashi (NPB’s Seibu Lions) will be posted this winter. Breakout infielder Sung Mun Song (KBO’s Kiwoom Heroes) is hoping to be posted for big league clubs as well. ESPN’s Jeff Passan reports this morning that Yomiuri Giants third baseman Kazuma Okamoto and Seibu Lions righty Tatsuya Imai are also hoping to be posted by their clubs and make the jump to Major League Baseball.

The hope of being posted is notable, but that also does not guarantee either player will be available to North American clubs this winter. Yakyu Cosmopolitan — a terrific source for English-speaking fans with an interest in Japanese baseball — points out that NPB’s Giants are a typically anti-posting club who rarely make their stars available to MLB teams. Okamoto is the Giants’ captain. The Lions are more amenable to posting players, but they’ve already agreed to post Takahashi. Posting two members of their rotation would be difficult, but YC notes that Imai would be a true free agent after the 2026 season. The Lions could lose him for nothing in the 2026-27 offseason anyhow.

Okamoto turned 29 in June. He’s a six-time All-Star and two-time Gold Glove winner who’s thrice led NPB in home runs. He missed more than three months of the current season after injuring his elbow in a collision at first base, but he’s healthy again and is batting .304/.385/.585 with 11 homers, 13 doubles, a triple and nearly as many walks (10.2%) as strikeouts (11.2%) in 196 plate appearances. Okamoto averaged 34 homers per season from 2018-23, “slipped” to 27 last year, and is now homering at the third-best rate of his career (once every 17.8 plate appearances).

Okamoto has been on the radar of MLB scouts for several years now, but if the Giants are going to post him, this will be the time to do it. Like Imai, he’ll have the requisite nine years of service to become a true free agent after the 2026 season. That hasn’t stopped the Yomiuri club from holding onto stars in the past. However, if Okamoto is set on eventually making a move to North America, the Giants’ decision boils down to posting him now and reaping a notable sum via the posting system or allowing him to walk with no compensation next winter.

The right-handed-hitting Okamoto played primarily third base early in his NPB career, but he’s seen significant time at first and has a handful of starts in the outfield corners as well. Okamoto has split his time between the corners this year but was primarily a first baseman in 2024. Sports Info Solutions credited him with the Fielding Bible Award as NPB’s best defender at first base in 2024, and Passan suggests that some MLB teams feel he’s better suited at first than at third.

Eric Longenhagen of FanGraphs agrees, labeling Okamoto as a “likely first-base-only defender” in the majors but crediting his plus power and consistent ability to pull the ball with authority. Longenhagen notes that, as is the case with most NPB hitters, there are questions about Okamoto’s ability to hit big league fastballs. The average NPB fastball is around 91 mph, compared to this year’s 94.4 mph average four-seamer in MLB (via Statcast). Longenhagen writes that Okamoto’s numbers against heaters greater than 94 mph “fall off a cliff.” It’s a valid concern, though the counter is always that a hitter could potentially adapt to better velocity when seeing it more frequently. That uncertainty will be baked into eventual price of a free agent contract if Okamoto is posted.

Even if Okamoto is limited to primarily playing first base, he’s a good defender there by all accounts. He has plus power, improving contact skills and draws plenty of walks. Since settling in as a regular in his age-22 season, Okamoto is a .276/.360/.524 hitter with an average of 39 homers per 162 games played. He currently has a career-low strikeout rate and the second-best ISO (slugging minus batting average) of his career. If he’s posted, there will surely be multi-year interest from MLB clubs.

Imai’s possible addition to the market is arguably even more intriguing, given the heavy price teams are willing to pay for prime-aged pitching. The 5’11” righty won’t turn 28 until next May. He’s in the midst of a career-best season, sporting a comical 1.50 ERA with a 28.8% strikeout rate and 6.7% walk rate in 143 2/3 innings. Dating back to the 2022 season, Imai boasts a sensational 2.10 earned run average. Passan notes that the right-hander sits 95 mph with his heater and tops out at 99 mph, giving him the sort of power arsenal that’s quite rare in NPB.

An ankle injury held him to nine games back in 2022, but Imai has topped 130 innings in three seasons since and is averaging seven innings per start for a second consecutive season. He’s on pace for back-to-back seasons of more than 170 innings. (Bear in mind that the NPB season is 144 games, not 162 as in MLB, and Japanese pitchers typically only start once per week.) Imai currently ranks seventh in NPB in innings pitched, and the six names ahead of him all have at least one extra start over him. He’s averaged more innings per start than all but one of those pitchers ahead of him on that leaderboard.

Passan writes that he polled more than a dozen scouts and front office executives on the type of contract Imai could command, with estimates ranging from $80MM on the low end to nearly $200MM on the high end. He’ll be three years older than Yoshinobu Yamamoto was when he landed his precedent-setting $325MM contract with the Dodgers but two years younger than Shota Imanaga was when he signed a four-year, $53MM deal that now looks like a bargain for the Cubs (and still will even after Chicago picks up an option to push the deal to $80MM over five years).

If Imai is posted, he’ll join Dustin May and Michael Soroka as free agent starters heading into their age-28 seasons. Imai would have considerably more earning power than either, as big league teams will pay a premium for his power arsenal and the allure of the unknown. Based on Imai’s age, arsenal and recent track record, there’s a chance that he could be the highest-paid pitcher of the entire free agent class this winter — if the Lions eventually choose to make him available.

For those in need of a refresher, the MLB-NPB posting system allows Japanese teams to post their players for all 30 MLB teams at their discretion. Players that are 25 or older and have six-plus years of experience can sign major league contracts for any length and any amount. When a player is posted, that opens a 45-day window for him to negotiate with any and all interested MLB clubs.

When a deal is reached, the MLB team must pay a posting/release fee to the player’s former NPB club. That sum is equal to 20% of the contract’s first $25MM, 17.5% of the next $25MM and 15% of any money thereafter. That sum comes in addition to the contract. Any down-the-road earnings (e.g. club options, performance bonuses, etc.) are also factored in once they become guaranteed. For instance, if Imai were to sign a $125MM contract with an eventual club option for $25MM, his MLB team would owe the Lions an additional $3.75MM (15%) upon exercising that club option.

Kenta Maeda Plans To Pitch In Japan In 2026

By | at

In an appearance on TV Tokyo’s “Sports Real Live” show (Japanese language link from Yahoo Japan), Kenta Maeda said that he is leaving North American baseball behind at the conclusion of the 2025 season.  Maeda revealed that he initially made his decision after signing his two-year, $24MM deal with the Tigers that that would be his final contract with a Major League team, and he is hoping to continue his career in Japan with a Nippon Professional Baseball club in 2026.

Maeda (who turns 38 in April) began his pro career with eight seasons with the Hiroshima Carp before being posted for MLB clubs, and signing an incentive-heavy eight-year, $25MM deal with the Dodgers back in January 2016.  Maeda’s stint in North America has seen him suit up in nine Major League seasons, with the 2022 campaign missed entirely since he was recovering from a Tommy John surgery.

After struggling badly in the first year of his Tigers contract, a move to the bullpen didn’t change Maeda’s fortunes this year, and Detroit released the right-hander in early May.  He then joined the Cubs on a minor league contract before being released in early August, quickly landing with the Yankees on another minors deal.  Over 76 1/3 Triple-A innings this season, Maeda hasn’t shown any of his old form, posting a 6.25 ERA for New York and Chicago’s top affiliates.

During the TV Tokyo interview, Maeda said his family has been living in Japan during his year in the minors, in order to have some stability while Maeda has now bounced around to multiple teams.  His recent on-field results (or lack thereof) had no bearing on his decision, as Maeda stated that he would’ve returned to Japan after 2025 if he’d been a 20-game winner at the big league level.

Since it doesn’t look like the Yankees will be calling Maeda up in September, his MLB resume could be closed after 226 games (172 of them starts) with the Tigers, Twins, and Dodgers over parts of nine seasons.  Maeda has a 4.20 ERA, 25.8% strikeout rate, and 7.8% walk rate over 986 2/3 career innings in the regular season, as well as a 3.24 ERA across 41 2/3 career postseason frames with Minnesota and Los Angeles.

Though his final act in Detroit didn’t go well, Maeda was generally a very effective pitcher in the majors.  He had a 3.87 ERA during 589 innings in L.A., with the Dodgers using Maeda both as a starter and as a reliever, though Maeda made it known that he preferred rotation work.  A trade to the Twins prior to the 2020 season gave Maeda a full-fledged starting job, and he responded with a runner-up finish in AL Cy Young Award voting, posting a 2.70 ERA in 66 2/3 innings during the pandemic-shortened season.  He wasn’t as effective during a 2021 campaign that was cut short by his Tommy John procedure, though Maeda returned in solid form (4.23 ERA in 104 1/3 IP) for Minnesota’s AL Central-winning team in 2023.

NPB’s Seibu Lions Likely To Post Kona Takahashi For MLB Teams This Offseason

By | at

The Seibu Lions have agreed to post right-hander Kona Takahashi for Major League teams this winter, according to a report from Nikkai Sports.  Takahashi turns 29 in February, and he has a 2.95 ERA, 13.8% strikeout rate, and 6.9% walk rate over 116 innings and 19 starts for the Lions this season, which is his 11th campaign in Nippon Professional Baseball.

The numbers reflect something of a bounce-back for Takahashi, who had a 3.87 ERA over 81 1/3 frames in 2024 and a rather glaring 0-11 record.  Even with the caveat that win-loss records aren’t the best indicator of performance, it was a far cry from the form that saw Takahashi deliver a 2.20 ERA during the 2022-23 seasons, as his tough year included a drop in velocity and even some time in the Japanese minor leagues.

Takahashi first expressed an interest in coming to MLB after his big 2022 campaign, and though he has appeared in each of the last 11 NPB seasons, he still hasn’t amassed the full nine years of service time necessary for full free agency.  The Lions have nevertheless agreed to let Takahashi search for a Major League team a bit early, and landing a contract would allow the Lions to gain some money via a posting fee.

Once an NPB player is posted, he has 45 days to work out a deal with a Major League club.  If no deal is reached, the player returns to his Nippon Professional Baseball club for the next season and can’t be posted again until the following winter.  If a deal is reached, the player’s original NPB club earns a posting fee depending on the size of his MLB contract.  Should the player sign a big league deal worth $25MM or less in guaranteed money, the NPB team will receive 20 percent of the total guarantee.  If the player signs a minor league deal, the NPB team will get 25 percent of the signing bonus, plus a later supplemental free if the player is added to the MLB team’s active roster.

It seems likely that any contract Takahashi lands will be within the lower ranges of the posting system, as the Yakyu Cosmopolitan writes that Takahashi’s “market will be similar to” that of Shinnosuke Ogasawara or Naoyuki Uwasawa.  Ogasawara signed a two-year, $3.5MM contract with the Nationals last January after being posted by the Chunichi Dragons, and Uwasawa signed a non-guaranteed split contract with the Rays in January 2024 after the Nippon Ham Fighters posted the right-hander.

Takahashi has solid control but isn’t much of a strikeout pitcher, as his 20% strikeout rate from the 2020 season (over 120 1/3 innings) is his career high in Japan.  MLB teams may be looking at him more as reliever or a swingman than as a rotation candidate, but the ever-present need for pitching means that Takahashi has a solid chance of landing some kind of a deal to get to the majors in 2026.  The Nikkai report indicates that evaluators from the Angels, Athletics, Blue Jays, Cardinals, Mariners, and Rangers recently scouted one of Takahashi’s starts, so the right-hander is getting at least some due-diligence interest from a range of teams.

Shintaro Fujinami Signs With NPB’s Yokohama DeNA BayStars

By | at

Former big leaguer Shintaro Fujinami has returned to Japan. He signed with the Yokohama DeNA BayStars of Nippon Professional Baseball, the team announced. The hard-throwing righty was released from a minor league deal with the Mariners last month.

This probably marks the end of Fujinami’s two and a half seasons in affiliated ball. The 6’6″ righty has an upper-90s fastball but hasn’t been able to harness his stuff. The rebuilding A’s took a one-year, $3.25MM flier on Fujinami in advance of the 2023 season. They initially gave him a rotation opportunity, but he struggled mightily in seven starts and quickly moved to the bullpen.

While Fujinami had an 8.57 ERA in 34 appearances with the A’s, they managed to flip him to the Orioles at the trade deadline. He tallied 29 2/3 frames of 4.85 ERA ball for Baltimore. Fujinami secured a big league split deal from the Mets in his return to free agency. He never made an MLB appearance with New York, spending time on the injured list before being designated for assignment.

Fujinami pitched in Puerto Rico over the winter to land another affiliated opportunity. He secured a minor league contract with Seattle in January but struggled to a 5.79 ERA with 26 walks in 18 2/3 Triple-A innings. He’ll now head back to NPB, where he owns a 3.41 earned run average in parts of 10 seasons.

Grant Hartwig Signs With NPB’s Hanshin Tigers

By | at

Reliever Grant Hartwig has signed with the Hanshin Tigers of Japan’s Nippon Professional Baseball. The 6’5″ righty had been on a minor league contract with the Mets but was released last month. It seems that was to pursue this opportunity.

Hartwig, 27, pitched in the big leagues for the Mets in each of the previous two seasons. He logged 35 1/3 innings of 4.84 ERA ball as a rookie in 2023. He spent most of last year in Triple-A and lost a couple months to a meniscus tear that required surgery. Hartwig appeared in four MLB games, allowing six runs in 6 2/3 innings. The Mets dropped him from the 40-man roster early in the offseason and brought him back on a minor league deal.

A product of Miami Ohio, Hartwig signed with the Mets in 2021 as an undrafted free agent. He has turned in a 3.42 earned run average in parts of five minor league campaigns. Hartwig had a matching 3.42 ERA across 23 2/3 Triple-A frames this year, though he bizarrely surrendered 13 unearned runs (against nine earned) in 21 appearances. He fanned 29% of batters faced with a solid 8.8% walk rate while averaging nearly 95 MPH on his sinker. Hartwig will presumably lock in a stronger guarantee in NPB than he would’ve made had he played out the season in Triple-A.

Michael Chavis Signs With NPB’s Chunichi Dragons

By | at

Infielder Michael Chavis is heading overseas. The CAA client has signed with the Chunichi Dragons of Japan’s Nippon Professional Baseball, per an announcement from Chunichi. He had been with the Dodgers on a minor league deal but was released to pursue this new opportunity.

Chavis, now 29, was once a notable prospect in the Red Sox’ system. Boston grabbed him with the 26th overall pick in the 2014 draft and he hit well as he climbed the minor league ladder. Baseball America ranked him the #85 prospect in the league in 2018.

The following year, he had an enticing debut, as he hit 18 home runs in just 95 games for the Sox. However, that power production came with a worrisome 33.2% strikeout rate, and that concern ultimately proved to be lingering. As the strikeout woes continued, he bounced around the league, also appearing for the Pirates and Nationals. Overall, he stepped to the plate 1,186 times in 357 games from 2020 to 2023. He hit 42 homers but was punched out at a 31.9% clip.

In 2024 and 2025, he’s been stuck in Triple-A, having signed minor league deals with the Mariners, White Sox and Dodgers. He has slashed .270/.339/.483 over that time with a lower 22.3% strikeout rate but without any of those clubs giving him a shot in the majors.

By heading overseas, Chavis will presumably be getting a bit of a pay bump relative to whatever he was making in the minors. If he can perform well for the Dragons, he could perhaps parlay that into a return to North America or another deal in Japan or other foreign league.

J.D. Davis Signs With NPB’s Seibu Lions

By | at

Veteran infielder J.D. Davis has signed with the Seibu Lions of Japan’s Nippon Professional Baseball, per an announcement from the club. Davis, a client of ALIGND Sports, will play out the remainder of the 2025 season in Japan.

Davis, 32, has spent the year in the Angels organization. They released him on June 30, presumably to allow him to finalize this opportunity. Davis appeared in five big league games and went 1-for-9. He’s spent the bulk of the year in Triple-A Salt Lake, slashing .294/.371/.524 with 10 homers, 11 doubles, a triple, a 10% walk rate and a 26.3% strikeout rate.

A former third-round pick of the Astros in 2014, Davis has amassed more than six years of major league service time. From 2019-23, he was a productive part-time player with the Mets and Giants, batting a combined .268/.352/.443 with 63 home runs in 1804 plate appearances. His production since that time has evaporated, albeit in minimal playing time. Davis hit just .218/.293/.336 last year in 157 plate appearances between the A’s and Yankees. He also struggled badly in 136 Triple-A plate appearances between the Orioles and A’s.

All told, Davis heads to Japan with a career .257/.339/.423 batting line in 2151 major league plate appearances. A strong showing overseas could garner him some renewed interest in the big leagues or perhaps open him up for an extension or another free-agent deal that would come with a more substantial guarantee than he could expect in North America, where he’s been relegated to minor league deals over the past calendar year.

Jose Barrero Elects Free Agency

By | at

Infielder/outfielder Jose Barrero, who was recently designated for assignment by the Cardinals, went unclaimed on waivers and has rejected an outright assignment in favor of free agency, MLBTR has learned. Barrero will explore opportunities around the league but also has interest from at least one team in Japan’s Nippon Professional Baseball and is weighing whether to pursue an overseas opportunity.

Barrero, 27, appeared in 22 games with the Cardinals but was only given 31 plate appearances. He hit just .138/.194/.276 in that scattershot playing time. This was his fifth season of big league work, but he’s yet to deliver on his former top prospect billing in the majors, with a .182/.238/.257 slash in 478 plate appearances between the Reds (who initially signed him out of Cuba) and Cardinals.

Although Barrero hasn’t yet found his stride in the majors, he has a more solid track record in Triple-A. He’s a career .247/.324/.475 hitter in parts of five seasons there, including a huge .299/.396/.517 showing in 101 plate appearances with the Cardinals’ Memphis affiliate in 2025. In 252 Triple-A games, Barrero has swatted 51 homers and gone 48-for-56 (86%) in stolen base attempts.

Barrero has primarily been a shortstop, logging more than 5100 innings at the position since turning pro, but he’s gradually begun to see time at other positions as well in recent years. He’s played just shy of 300 innings at second base and 94 innings at third base, but his most frequent non-shortstop position has been center field, where he’s now piled up 719 innings. There are some justifiable concerns about his hit tool — Barrero has fanned in 30% of his Triple-A plate appearances — but Barrero offers an enticing blend of power and speed as well as the ability to play multiple up-the-middle positions on the defensive end of things.

Tyler Nevin Signs Two-Year Extension With NPB’s Seibu Lions

By | at

The Seibu Lions of Japan’s Nippon Professional Baseball announced that they have signed infielder Tyler Nevin to a two-year extension beginning in 2026. Salary figures were not included. “I’d like to express my sincere gratitude to my teammates, staff, and fans who have trusted me and supported me since the day I arrived in Japan,” Nevin said in a Japanese statement relayed by the team, per Google Translate. “I will strive to make the rest of the season even better and focus on the game in front of me. I can’t wait for the next two years. Awesome!”

Nevin, 28, signed with the Lions in January. His Japanese career has gotten out to a solid start through his first 68 games. His .269/.330/.379 batting line may not be overwhelming in a vacuum but actually translates to a 120 wRC+ in NPB this year. It seems that the club has been pleased enough with that performance to lock him up.

Considering the way Nevin’s career went before this year, it’s understandable that he would agree to be locked up. Broadly speaking, he had always hit in the minors but failed to do so in the majors. From 2022 to 2024, he stepped to the plate 639 times at the Triple-A level. He hit 26 home runs and drew walks at a 10.2% clip while only striking out 17.5% of the time. He had a combined batting line of .313/.391/.536 and a 137 wRC+.

That minor league performance got him a few major league looks from the Orioles, Tigers and Athletics, but he wasn’t able to do much with those chances. He got 591 big league plate appearances over the past few years with a .204/.299/.315 line and 81 wRC+. He exhausted his final option year in 2023, which put him into a fringe roster status. He spent 2024 bouncing on and off the Athletics’ roster, clearing waivers multiple times throughout the year. Finding regular playing time in the big leagues would have been difficult going forward.

Rather than spend another year grinding through the roster bubble lifestyle, he accepted a chance to head overseas and perhaps find some stability. Given that he’s having a decent year, he could have tried to parlay that into a return to North America in 2026. But there would have been no guarantee of that working out, so it’s easy to see the logic in him sticking with the Lions for another few years.

Though the salary figures haven’t been reported for this deal, North American players getting regular work in Japan often get paid in the vicinity of $1MM annually. That’s more than players in the minors in North America get and even more than pre-arbitration major leaguers. Whatever his salary is, Nevin will get a bit of cash and some job security for his age-29 and age-30 seasons. If he can make the most of that regular role, he could perhaps try to return to affiliated ball a few years from now or secure himself another deal to continue playing in Asia.

NPB’s Rakuten Eagles Sign Luke Voit

By | at

The Tohoku Rakuten Golden Eagles of Nippon Professional Baseball have signed Luke Voit to a contract for the remainder of the 2025 season.  News of the signing first emerged a couple of weeks ago, and Voit just this weekend arrived in Japan once terms were finalized.

Voit is best known for his torrid stretch of hitting with the Yankees from 2018-2020.  Acquired at the 2018 trade deadline in a deal with the Cardinals, Voit immediately caught fire once donning the pinstripes, and quickly became a lineup fixture as a first baseman and DH.  Voit’s huge run was highlighted by a 22-homer season in 2020, which led the major leagues during the pandemic-shortened campaign.

Injuries limited Voit to just 68 games in 2021, however, and the Yankees parted ways with Voit by dealing him to the Padres during the spring of 2022.  Since that deal, Voit hit only .225/.305/.386 with 22 homers over 642 plate appearances with San Diego, Washington, and Milwaukee over the 2022-23 season, and he hasn’t appeared in the majors since his brief stint with the Brewers in 2023.

Voit signed a pair of minor league contracts with the Mets that didn’t result in any time in the big leagues, and his pro experience in 2024-25 has consisted of 122 games with two different Mexican League clubs.  Since the 34-year-old Voit has been crushing Mexican League pitching, he might have something to offer the Golden Eagles as a veteran bat.  The Eagles are last in NPB in home runs, with only 25 long balls over 66 games this season.
