Nippon Professional Baseball

Bryan Sammons Signs With NPB’s Chiba Lotte Marines

By Steve Adams | December 13, 2024 at 10:07am CDT

Former Tigers left-hander Bryan Sammons has signed a one-year deal with Nippon Professional Baseball’s Chiba Lotte Marines, per announcements from the team and from Sammons’ agency, GSI.

Sammons made his big league debut as a 29-year-old rookie this past season, pitching 27 1/3 innings of 3.62 ERA ball for the Tigers during their Cinderella push to the playoffs. The 6’4″ southpaw averaged 91.5 mph on his heater, fanned 17.3% of his opponents and logged a 8.7% walk rate. Sammons spent the bulk of his 2024 season in Triple-A Toledo, where he pitched 102 innings with a 4.15 ERA, 23.1% strikeout rate and 10% walk rate. Detroit outrighted Sammons off the 40-man roster after the season, and he became a minor league free agent.

The move to Japan is the latest step in the type of baseball odyssey for which all fans love to cheer. The Athletic’s Cody Stavenhagen penned a fantastic look at Sammons’ journey from under-recruited high schooler to an eighth-round pick of the Twins who wound up being released both by Minnesota and by Houston. (Readers are highly encouraged to check out Stavenhagen’s piece in full.) Sammons, who graduated from Western Carolina with an engineering degree, contemplated giving up baseball entirely to pursue a more traditional career before taking one last shot and pitching in the Atlantic League. Just over a year later, he was on the mound at Comerica Park.

While Sammons is joining the same team for which Roki Sasaki has starred in his NPB career, he’s effectively taking the place of veteran lefty Dallas Keuchel, who started eight games for the Marines in the second half of the 2024 NPB season. The Marines announced in early December that Keuchel had been released and was a free agent. Sammons’ role will be determined, but manager Masahito Yoshii said his hope is that Sammons can pitch out of the rotation in 2025 (link via Yahoo Japan).

Agent Joel Wolfe On Roki Sasaki’s Free Agency

By Steve Adams | December 12, 2024 at 11:59pm CDT

Agent Joel Wolfe of Wasserman held court with the media at this week’s Winter Meetings in Dallas to discuss a variety of topics, headlined by an overview of the plan for newly posted right-hander Roki Sasaki. MLBTR was on hand as Wolfe discussed Sasaki, the 23-year-old ace of Japan’s Chiba Lotte Marines, who is now eligible to negotiate with all major league teams.

Because of his age, Sasaki is subject to Major League Baseball’s international amateur guidelines; more specifically, that means he can only sign a minor league deal and receive a bonus that fits within his team’s league-allotted, hard-capped bonus pool. Had Sasaki waited two years to come to the majors, he’d have been 25 and thus qualified as an amateur, possibly setting him up for a contract rivaling that of countryman and current Dodgers righty Yoshinobu Yamamoto (12 years, $325MM).

Asked why Sasaki chose to seek a posting now rather than come to the majors as a true free agent in two years — potentially leaving hundreds of millions of dollars on the table — Wolfe indicated he’d been asked that question “by everyone you can imagine” and attempted to answer to the best of his ability.

“It’s a difficult question to answer. Some of it is Japanese culture. Some of it is just Roki Sasaki. There are no absolutes in baseball and, through Roki’s eyes, there are no absolutes in life. … He does not take anything for granted. It is not an absolute lock, as some people in baseball have assumed, that two years from now he’s going to get a Yamamoto contract. Sometimes, baseball just doesn’t work out. You know, you look at the epidemic of injuries that pitchers suffer. You could have Tommy John surgery. He’s had two shoulder injuries. He’s had an oblique injury. Things may not go the way you want.

“The other thing is, it’s always been his dream to come to the major leagues, since he was in school. He’s grown up idolizing players like Yu Darvish, Masahiro Tanaka, Daisuke Matsuzaka. This is something he’s always wanted to do, and when he went to [the World Baseball Classic] and was around some of these major league players, it really rubbed off on him. He became sure that ’this is what I want to do as soon as possible.'”

With regard to what sort of factors Sasaki will prioritize in his free agency, Wolfe was more vague. He indicated that he and his client have yet to even discuss such factors at length, as Sasaki’s primary focus for so long has been on whether he’ll be posted at all. Wolfe noted that some teams have already submitted presentations for Sasaki but that in-person meetings have yet to begin. Wolfe himself said he’s seen “three or four” of the presentations that have been submitted but added that he expects more to file in. Asked how many teams scouted Sasaki this past season in Japan, Wolfe replied that at least half the league had done so.

Wolfe naturally declined to specify which teams had submitted initial presentations or scouted his client in person. The immediate focus for Sasaki will simply be learning about the teams, organizations and cities among which he’ll choose. He’s slated to arrive in the United States this week, and after reviewing the introductory presentations from interested teams, Sasaki and Wolfe will host teams for a first-round of in-person visits at a central location, beginning next week. Additional waves of team visits — perhaps some in the cities of the finalists — will take place down the road, but Sasaki also plans to return to Japan for a week or two during the upcoming holidays.

Asked specifically whether Sasaki might consider a small market, Wolfe said he it could possibly be of interest but emphasized that he had not confirmed as much with his client:

“Yeah, absolutely. I mean, I think there’s an argument to be made that a small- or mid-market team might be more beneficial for him, as a soft landing, coming from Japan and what he’s been through and not having an enjoyable experience with the media — it might be. I’m not saying it will be, but I don’t know how he’s going to do it. It might be beneficial for him to be in a smaller market, but I really don’t know how he looks at it yet because I haven’t had a chance and discuss it with him [at great length].”

Wolfe spoke at multiple points, once doing so unprompted, about the media coverage of Sasaki in Japan, labeling it “in my personal opinion, a bit unfair” and candidly acknowledging that at times it could have a negative impact on the young right-hander:

“There has been a lot of negativity in the media directed at him because he has expressed interest in going to play for MLB at such a young age. That’s considered in Japan to be very disrespectful and sort of swimming upstream. There’s been a lot of things. A lot of people jumped on board, creating false rumors about him and his family, and it was detrimental to his mental state.”

Wolfe also emphasized that wherever Sasaki lands, it won’t be a pure short-term financial decision:

“Given that the gap in bonus pool amounts is so negligible, my advice to him is: don’t make decisions based on that. The long-term arc of your career is where you’re going to earn your money, so it’s probably not advisable to make a short-term decision in that regard. Take all the factors into consideration.”

Sasaki was officially posted for major league teams on Dec. 9, kicking off a 45-day negotiating period for big league clubs. He’ll have to have a contract finalized by Jan. 23. Wolfe noted that the signing is expected to occur after Jan. 15, so it can fall under the purview of the 2025 international free agent period, which begins that day. While Sasaki’s decision won’t be a purely financial one, Wolfe specified that MLB wanted to ensure as much of a “level playing field” as possible and ensure that both Sasaki and his former team would get the most beneficial deal possible, which is the posting was formalized on Dec. 9, giving him the chance to extend his free agency into next year’s period — when all 30 MLB teams will have more international resources available.

It’ll be a tough pill for the Marines to swallow, regardless. Under the NPB/MLB posting system, NPB players’ former teams receive a release fee equal to 20% of the contract’s first $25MM, 17.5% of the next $25MM and 15% of any money thereafter. In Yamamoto’s case, for instance, his former club received a mammoth $54.375MM release fee from the Dodgers for agreeing to let Yamamoto go. Since Sasaki will be signing for a hard-capped bonus that’ll likely come in south of $10MM, the Marines will probably receive a release fee under $2MM.

Sasaki has pitched in parts of four NPB seasons and tallied 414 2/3 innings of 2.02 ERA ball with a 32.4% strikeout rate and 5.6% walk rate. Any team that signs him will have control of him for at least six seasons. He cannot sign an immediate extension following his minor league deal, pursuant to attachment 46 of the 2022-26 collective bargaining agreement, which indicates that any contracts deemed to be a circumvention of the CBA will not be permitted by the commissioner’s office. Wolfe noted that MLB teams cannot technically even promise Sasaki a spot on the big league roster when signing him, let alone broker an extension ahead of time at a to-be-determined date.

It’s possible, in theory, that Sasaki could sign an extension later in his young MLB career — likely more than a year or two down the road — but Wolfe pushed back on the notion that they’d even be amenable to that. “If he’s really, really good, the leverage would be on our side, so there wouldn’t be much incentive for us to sign a long-term extension.”

Rakuten Eagles Sign Spencer Howard, Miguel Yajure

By Leo Morgenstern | December 10, 2024 at 12:29pm CDT

The Rakuten Eagles of Nippon Professional Baseball have signed right-handed pitchers Spencer Howard and Miguel Yajure, the team announced. Both pitchers will presumably join the Eagles starting rotation. The 2025 season will be Howard’s first in NPB and Yajure’s second.

Howard, 28, was once a promising prospect in the Phillies organization but struggled to translate his minor league skills to the major league level. Over parts of five seasons with the Phillies, Rangers, Giants, and Guardians, he put up a 7.00 ERA in 144 innings of work. His underlying numbers, including a 4.77 SIERA, are better than his unsightly ERA, but no matter what statistics you look at, it’s clear Howard could not reliably retire MLB hitters. He has also struggled in the minors in recent years, putting up a 7.07 ERA and 6.20 FIP in 70 innings at Triple-A from 2022-24. Thus, the righty will look for a fresh start with the Eagles in 2025.

Yajure, 27 in May, made his MLB debut for the Yankees during the 2020 season. Over the next three years, he pitched 46 1/3 innings for the Yankees and Pirates, putting up a 7.58 ERA – even higher than Howard’s. His 5.37 SIERA was similarly poor, as was his low strikeout rate and high walk rate. If you include hit-by-pitches, he issued nearly as many free passes (32) as strikeouts (35). So, he set out in hopes of finding greener pastures across the pond last winter. Indeed, that’s exactly what he found. Yajure signed a one-year contract with the Yakult Swallows ahead of the 2024 season. With the Swallows, he pitched to a 3.34 ERA over 129 1/3 innings. A mid-3.00s ERA in NPB isn’t quite as impressive as it would be in MLB, but Yajure was a solid contributor for the Swallows, finishing second on the team in innings pitched. It was enough to convince the Eagles to give him a contract for 2025. He’ll look to build upon a solid first season in his sophomore NPB campaign.

Shinnosuke Ogasawara Officially Posted For MLB Clubs

By Darragh McDonald | December 10, 2024 at 10:10am CDT

Left-hander Shinnosuke Ogasawara has been officially posted by the Chunichi Dragons of Japan’s Nippon Professional Baseball, per reporter Francys Romero (X link). That opens up a 45-day window for his representatives at William Morris Endeavor to negotiate with major league clubs. If no deal is reached in that time, the southpaw will return to the Dragons for 2025.

It was reported back in October that the Dragons would make Ogasawara available via the posting system and that has now been rubber-stamped. The 30 MLB clubs can now officially speak to his representatives and see what sort of contract will be necessary to get him to put pen to paper.

While Ogasawara should generate interest, he’s clearly not exciting as Roki Sasaki, who has also been posted for clubs this offseason. However, Ogasawara likely has more earning power than Sasaki due to the binary nature of MLB international signing rules.

Players need to be 25 years old and have six seasons of experience in a foreign professional league in order to be considered “professionals” and have the right to freely negotiate a contract of any size and length. Players who don’t meet those criteria are considered “amateurs” and are therefore subject to the international bonus pool system, where each club gets $5-8MM annually to spend on such players. Sasaki is only 23 years old and will therefore be limited to a minor league deal with a signing bonus of a few million bucks. Ogasawara, on the other hand, is 27 years old and has appeared in parts of 9 NPB seasons. That means he has the freedom to fully assess his earning power and market himself to the highest bidder.

How much interest North American clubs will have in him is unknown. Ogasawara has had some success, but not as much as some other pitchers that have recently come over like Yoshinobu Yamamoto or Shota Imanaga. He has thrown 951 1/3 innings over his NPB career,  though striking out just 18.9% of batters faced. For context, MLB average is usually in the 22-23% range these days. He did get his strikeout rate up to 24% in 2022 but it dropped to 20.1% last year and then all the way to 13.6% in 2024.

The lack of punchouts hasn’t stopped him from succeeding in Japan, as he has a 3.62 earned run average over his career and had a 3.12 ERA in the season that just finished, though MLB clubs might wonder if the same pitch-to-contact approach could carry over to North American ball.

Ogasawara is also on the smaller side for a starting pitcher, listed at 5’11” and 183 pounds. That’s actually slightly larger than the 5’10” and 175 pounds listed for Imanaga, so it’s not a total disqualification, but Imanaga managed to strike out 25% of batters faced in his NPB career.

Though even if Ogasawara is a notch below Imanaga, he could still generate interest. Youth is clearly an attractive quality which is why guys like Yamamoto, Jung Hoo Lee and Juan Soto have been paid so well, so the fact that Ogasawara just turned 27 in October will work in his favor. The recent downturn in strikeouts is a bit concerning but he also lowered his walk rate to a tiny 3.7% rate in 2024 and the ERA was still good.

It’s difficult to forecast a contract for a player coming from another league like Ogasawara but MLBTR predicted after the start of the offseason that he could land a two-year, $12MM deal. Perhaps he could benefit from the fact that the market for mid-rotation starters has been quite strong so far this winter. Each of Luis Severino, Yusei Kikuchi, Frankie Montas, Matthew Boyd and Clay Holmes have earned larger guaranteed than projected in recent weeks, which could perhaps trickle down to Ogasawara.

The lefty and his team will have more than a month to feel out the market and gauge interest. For clubs still looking to add in the rotation but who don’t want to pay for top names like Corbin Burnes, Max Fried or Jack Flaherty, Ogasawara will be part of a mid-rotation or back-end group that still includes Sean Manaea, Nathan Eovaldi, Jeff Hoffman, Nick Pivetta, Andrew Heaney, Jose Quintana, Max Scherzer, Justin Verlander and others.

Marlins Release Mike Baumann To Pursue NPB Opportunity

By Anthony Franco | December 9, 2024 at 7:22pm CDT

7:22pm: Baumann is actually headed to Japan. Kiley McDaniel of ESPN reports (on X) that the CAA client has agreed to a deal with the Yakult Swallows of Nippon Professional Baseball.

7:13pm: The Marlins released reliever Mike Baumann, as first reflected on the MLB.com transaction tracker. Miami’s 40-man roster count drops to 39.

Baumann landed with the Fish on a waiver claim in late August. They were rather incredibly his fifth team of the season. The out-of-options righty bounced around as the last man in the bullpen for each of the Orioles, Mariners, Giants and Angels as well. Baumann didn’t pitch especially well for any of those clubs. He finished the year with a 5.55 earned run average over 58 1/3 innings. His 22% strikeout percentage wasn’t far off the MLB average, but he walked an elevated 10.6% of opponents while giving up plenty of hard contact.

The 29-year-old was a capable middle reliever for the Orioles as recently as 2023. He worked to a 3.76 ERA in a career-high 64 2/3 innings with Baltimore two seasons ago. Assuming he clears release waivers, Baumann will become a free agent. He’s probably looking at minor league deals but won’t have any issue getting a non-roster invite to MLB camp.

As for Miami, the move appears to be related to Wednesday’s Rule 5 draft. The Fish could not have made a selection if they went into the draft with a full 40-man roster. Miami picks third behind the White Sox and Rockies. The Marlins could have a target of their own in mind or try to work out a draft-and-trade with a team that sits lower in the order.

Roki Sasaki Officially Posted For MLB Clubs

By Darragh McDonald | December 9, 2024 at 10:00am CDT

Right-hander Roki Sasaki has been officially posted by the Chiba Lotte Marines of Japan’s Nippon Professional Baseball, per Jon Morosi of MLB Network (X link) and Mark Feinsand of MLB.com (X link). That opens a 45-day window for Sasaki and his representatives to talk to MLB clubs, meaning he will need to have a deal in place by January 23 or else he will return to the Marines.

Since Sasaki is under 25 years old, having just turned 23, he is considered an amateur under MLB rules. As such, he must be signed as part of the international bonus pool system. The 2024 international signing period ends on December 15 and the 2025 period starts on January 15. All reporting has suggested that Sasaki will wait to sign until the new period starts up and each club gets a fresh pool of spending money, so he seems destined to sign somewhere between January 15 and 23rd, though the talks can now officially begin.

It seems to be a lock that Sasaki will be coming to the majors next year, the only question is who he will play for. Money won’t be the primary factor, as each club will be able to offer a roughly similar signing bonus. As laid out by Ben Badler of Baseball America, each club has a bonus pool in the $5-8MM range. Teams can trade for more pool money but can’t increase their initial allotment by more than 60%.

If money were Sasaki’s motivation, he would have waited another two years to make this move. Yoshinobu Yamamoto was posted after his 25th birthday and was able to secure a $325MM guarantee from the Dodgers, but Sasaki has insisted on making the move now because he presumably just wants to test his mettle at the world’s top level as soon as possible.

He also surely knows that he will eventually be rewarded as long as he keeps pitching well. Shohei Ohtani also came to the majors as an amateur and had to settle for a small bonus with the Angels, but he flourished and eventually got his big paycheck from the Dodgers once he accrued six years of big league service time.

Given those parameters, Sasaki will likely be deciding his new club based on other factors. It has been suggested by some observers that the Dodgers are a favorite, given that the franchise has had success in general but also especially with pitchers. It’s also possible that the presence of Ohtani and Yamamoto might be nice for Sasaki as he makes the move to a new country and new culture. Some have also suggested the Padres as a strong contender since Sasaki reportedly has a strong relationship with Yu Darvish and might prefer to be in a market away from Ohtani and Yamamoto, giving him a greater chance to step into a spotlight and parlay that into sponsorships opportunities while his direct earning power is relatively low. He may have other preferences based on geography or a team’s competitive outlook, though those can only be guessed.

No club can be officially ruled out, however, given the cheap sticker price and Sasaki’s quality as a pitcher. He has allowed only 2.10 earned runs per nine innings over his NPB career, striking out 32.7% of batters faced while only giving out walks 5.7% of the time. There are some slight workload concerns since Sasaki has had some injuries and never thrown 130 innings in a season, but any club would still love to take a chance on him for the small price of a few million dollars.

Whoever ultimately lands Sasaki, it could lead to domino effects that impact other clubs. MLB teams generally commit their bonus pools years in advance via verbal agreements. Players in countries like the Dominican Republic and Venezuela aren’t allowed to sign until they are 16 years old but they often have handshake deals worked out with clubs years in advance. Whichever club agrees to sign Sasaki, even for a bonus of just a few million, might have to renege on a few of those verbal agreements. That would be an awful situation for those players but could lead to them suddenly becoming available for other clubs. That could create further domino effects if some clubs then back out of their own verbal agreements in order to pivot to the newly available players.

At Baseball America, Badler recently took a look at the chaos that could ensue as the Sasaki situation plays out. That will have to wait, as it likely won’t be known for over a month which team Sasaki will choose.

Kyle Keller Re-Signs With NPB’s Yomiuri Giants

By Nick Deeds | December 8, 2024 at 4:39pm CDT

Right-hander Kyle Keller has re-signed with the Yomiuri Giants of Nippon Professional Baseball, MLBTR has learned. Keller’s new contract is a one-year deal that includes a mutual option for the 2026 season, though specific financial terms remain unclear.

Keller, 31, was an 18th-round pick by Miami back in 2015 and made his big league debut with the club back in 2019. He ultimately spent three years in the majors with the Marlins, Angels, and Pirates. He struggled through 46 1/3 big league innings during that time with a 5.83 ERA and 7.00 FIP. While he struck out opponents at a decent 22.4% clip, he was held back by an untenable 14.7% walk rate that severely limited his effectiveness at the big league level. Those struggles in the big leagues led Keller to look overseas for his next opportunity, and he eventually signed with NPB’s Hanshin Tigers for the 2022 season.

The right-hander wound up acting as a prominent late-inning arm for the club over his two seasons with them. After dominating the Western League for the Tigers’ affiliate almost immediately, he found himself promoted to the Central League rather quickly and didn’t look back with a 3.31 ERA in 32 2/3 innings of work. Importantly, he showed far better command over his arsenal in NPB play with a fantastic 35.9% strikeout rate against a microscopic 3.9% walk rate during his first year in the Central League. His peripherals weren’t quite as stellar in his second season with the Tigers, as his 23.7% strikeout rate and 13.6% walk rate were more reminiscent of his time in the big leagues than anything else. That didn’t stop him from posting strong results, however, as he pitched to a 1.71 ERA in 26 1/3 innings of work.

Those strong results earned Keller interest both in NPB and from MLB clubs last winter, and he ultimately settled on a third season in NPB as he landed with the Yomiuri Giants on a one-year deal last winter. His 2024 season turned out to be the best of his NPB career so far as he dominated with a 1.53 ERA in 47 innings of work while flashing strong peripherals. Keller struck out an excellent 29.5% of opponents for the Giants last year, while his walk rate sat at a more manageable 10.4%. That combination of excellent results and solid peripherals backing the performance up was evidently enough convince the Giants to retain Keller for at least the 2025 season.

Given the recent MLB interest he’s received and his strong season last year, if Keller is able to turn in a similarly strong campaign at age-32 next year it wouldn’t be hard to imagine him exploring a return to stateside ball at some point in the future as other successful big league relievers like Robert Suarez have done in the past.

Roki Sasaki Expected To Be Posted During Winter Meetings

By Mark Polishuk | December 7, 2024 at 9:54am CDT

Roki Sasaki’s official arrival into the free agent market will likely take place during baseball’s Winter Meetings, as ESPN’s Jeff Passan reports that the star right-hander is expected to be posted by the Chiba Lotte Marines on Tuesday.  Once posted, Major League teams have 45 days to negotiate with Sasaki, and he’ll return to the Marines for the 2025 Nippon Professional Baseball season if no deal is reached.

It is seen as a virtual lock that Sasaki will be coming to MLB, given how the 23-year-old is so eager to pitch in the big leagues that he is leaving a fortune on the table by coming to North America so early in his career.  Since Sasaki is an international free agent who is less than 25 years old, he can only be signed using funds from a team’s international bonus pool.

The timing of the posting is noteworthy, as Sasaki’s 45-day negotiating window will stretch beyond January 15 and the opening of the 2025 international signing period.  Since the 2024 period ends on December 15 and teams have already basically spent everything in their budgets, it was widely expected that Sasaki will wait until after January 15 to sign so he could land at least a little more money.  Unofficially, teams have had deals in place with international prospects for years in advance of the 2025 int’l window, yet if necessary, it is expected that some teams will walk away from these under-the-table deals if it means giving their entire 2025 bonus pool over to Sasaki.

However, as Sasaki’s early foray to the big leagues indicates, money is far from his chief motivator.  Pitching in Major League Baseball will help Sasaki on the endorsement front, of course, but the circumstances of his arrival creates one of the more interesting free agent cases in recent years — arguably the most interesting since Shohei Ohtani’s arrival in the 2017-18 offseason, as Ohtani also came to the majors in advance of his age-23 season.

Though the financial playing field is fairly level for all 30 teams to make a play for Sasaki’s services, the big-spending Dodgers have long been seen a favorite to sign the right-hander, to the point that agent Joel Wolfe vehemently denied rumors that Sasaki and the Dodgers had already worked out some kind of unofficial agreement.  There’s obvious appeal for Sasaki in joining a championship team that already has such Japanese stars as Ohtani and Yoshinobu Yamamoto on the roster, though it isn’t known what exactly Sasaki is looking for in a Major League destination (geographic preferences, teams with a pre-existing link to Japanese baseball, smaller or larger markets, etc.).  As such, it is easy to imagine Sasaki ending up with the Padres, Mets, Giants, Cubs, or any of the several other teams already known to have some interest in his services.

The Marines’ own financial return from Sasaki’s posting will be limited, as per the terms of the MLB/NPB posting system.  In addition to paying Sasaki, a Major League team will have to pay the Marines an extra fee based on the amount of Sasaki’s contract — 20% of a deal’s first $25MM, 17.5% of the next $25MM, and 15% of further spending.  Since Sasaki’s deal is naturally limited by the size of bonus pools, the Marines stand to gain less than $2MM for one of Japan’s top pitchers.

Over 394 2/3 career innings with the Marines, Sasaki has a 2.10 ERA, 32.73% strikeout rate, and 5.7% walk rate.  His devastating splitter and high-90s (topping 100mph in past seasons) have left NPB batters fooled, most memorably during a perfect game in 2022 that saw Sasaki record 13 straight strikeouts and 19 strikeouts overall.  Sasaki then gained worldwide attention by almost throwing another perfect game in his next start, as he tossed eight perfect innings before being removed due to concerns over his pitch count (102 pitches).

The relative lack of mileage on Sasaki’s arm is both a boon for MLB teams eager to land such a talented pitcher at such a young age, and a bit of a concern about a possible lack of durability.  Sasaki’s 129 1/3 innings in 2022 remains his career high, and his 2024 season was limited to 111 innings due to a torn oblique and some type of injury to his right arm.  That said, these factors have done nothing to limit the hype on Sasaki, and his arrival in Major League Baseball lines up as one of the key stories of the offseason.

NPB’s Hanshin Tigers Post Koyo Aoyagi For MLB Clubs

By Anthony Franco | December 4, 2024 at 6:45pm CDT

The Hanshin Tigers of Japan’s Nippon Professional Baseball announced last night that they’ve made right-hander Koyo Aoyagi available to major league teams via the posting system. Jon Morosi of the MLB Network tweets that MLB has approved the posting, which opens a 45-day window for the pitcher to sign with a big league team.

Aoyagi, who turns 31 next week, seems to project as a depth arm. While he has worked as a starting pitcher for the Tigers, Aoyagi throws from a sidearm slot that’s more commonly found in the bullpen. He’s coming off a pedestrian season which he split almost evenly between the Tigers and their minor league affiliate. Aoyagi made 12 starts at Japan’s top level and pitched 11 times in the minors.

During his work at the highest level, he turned in a 3.69 ERA across 61 innings. His 13% strikeout rate would be nearly 10 percentage points below the MLB average. He showed decent but not exceptional control, walking 7.8% of batters faced. His career track record is a bit more impressive. He owns a 3.08 ERA with a 17.1% strikeout percentage across nine NPB campaigns. This was his second consecutive middling season, though. Aoyagi was tagged for a 4.57 ERA across 100 1/3 innings for the Tigers in 2023.

The 5’11” hurler pitched for Japan at the 2020 Olympics (held in Tokyo a year late as a result of the pandemic). Japan went 5-0 and won the gold medal, though Aoyagi was tagged for five runs in 1 2/3 innings across two appearances. He did not make the nation’s World Baseball Classic roster two years later.

Assuming the posting window officially opened today, Aoyagi will have until January 17 to sign with an MLB team. If he doesn’t find an offer to his liking, he’d remain with the Tigers. Aoyagi’s numbers suggest he could be limited to a minor league deal. If he signs with an MLB team, that club would also owe a release fee to the Hanshin Tigers. The fee is proportional to the size of the contract. In the very likely event that he signs for $25MM or less, the posting fee would be 20% of the guarantee.

Tayron Guerrero Signs With NPB’s Chiba Lotte Marines

By Darragh McDonald | December 4, 2024 at 5:45pm CDT

The Chiba Lotte Marines of Japan’s Nippon Professional Baseball announced that they have signed right-hander Tayron Guerrero. Per reporter Francys Romero (X link), Guerrero will make a salary of $600K next year.

It’s a bit of a homecoming for Guerrero, 34 in January, as he also pitched for the Marines in 2022. He was in affiliated ball for over a decade prior to that but was only able to throw 106 major league innings. Splitting time between the Padres and Marlins, he posted a 5.77 earned run average from 2016 to 2019.

He wasn’t able to crack the big leagues in 2020 or 2021 so he headed to Japan in 2022 and had a nice season with the Marines. He tossed 46 innings over 49 appearances with a 3.52 ERA, 32.5% strikeout rate and 10.3% walk rate.

He came back to North America after that showing, signing a minor league deal with the Reds going into 2023. He struggled badly for Triple-A Louisville, with an 11.51 ERA over his 20 appearances, walking more batters than he struck out. He was released in June and then signed with the Diablos Rojos of the Mexican League. A 1.17 ERA over his eight appearances there was apparently enough for him to get a minor league deal with the Angels for the 2024 season.

He made 30 appearances at Triple-A Reno this year, in the hitter-friendly Pacific Coast League. His 5.73 ERA doesn’t look great but his 20.6% strikeout rate, 7.1% walk rate and 44% ground ball rate were all solid enough, leading to a 3.47 FIP.

If Guerrero stayed in North America, he surely would have been limited to minor league offers and would have had to fight his way to the big leagues. By returning to Japan, he has locked in a notable salary just a bit below next year’s MLB minimum, which will be $760K.
