Jose Ruiz Signs With NPB’s Yokohama BayStars

By | at

The Yokohama DeNA BayStars of Japan’s Nippon Professional Baseball announced yesterday that they’ve signed reliever José Ruiz. MLBTR’s Steve Adams reports that it’s a one-year deal with a 2027 club option. The OL Baseball Group client is guaranteed $1.2MM and can collect another $200K per season in incentives.

Ruiz, 31, split last season between the Phillies and Braves. He opened the year in Philadelphia’s big league bullpen but was hit hard, giving up 13 earned runs across 14 1/3 innings. They designated him for assignment and lost him on waivers to Atlanta at the beginning of June. Ruiz didn’t get much of a look from the Braves, who dropped him after he gave up three runs to the Rockies in his second appearance. He cleared waivers that time around and spent the rest of the season in Triple-A.

Atlanta flipped Ruiz to the Rangers as a salary offset in the Dane Dunning deal a month later. He didn’t make it back to the majors with Texas. The Venezuelan righty pitched well in Triple-A, though, combining for a 2.73 ERA in 33 innings. He struck out 24% of opponents against an excellent 5.4% walk percentage.

Ruiz has logged some big league action in each of the past nine seasons. He spent most of his career with the White Sox but was a useful middle reliever for the Phillies as recently as 2024. This is his first stint in Asia. The $1.2MM guarantee is better than he would’ve received had he sought minor league opportunities in affiliated ball. He’s young enough to explore a return down the line if he pitches well in Japan.

NPB’s Chiba Lotte Marines Sign Jose Castillo

By | at

The Chiba Lotte Marines of Nippon Professional Baseball announced the signing of left-hander Jose Castillo.  The Mets chose to non-tender Castillo earlier this month, passing on the southpaw’s projected $1.7MM arbitration salary.

The move overseas to Japan may seem like small potatoes given the transactional maelstrom that was Castillo’s 2025 season.  He saw big league action for four different teams (the Diamondbacks, Mets, Mariners, and Orioles) while compiling a 3.94 ERA over 32 innings.  Beginning the season on a minor league deal with Arizona, Castillo was designated for assignment in May and then traded to the Mets, and he subsequently bounced around on a series of waiver claims.  Castillo actually had three separate stints with the Mets, with the latest coming in early November when he was claimed off Baltimore’s waiver wire.

Castillo is out of minor league options, making him a necessary DFA candidate whenever a team wants to move him off its active roster.  He would probably be facing another round of designations, outright assignments, and waiver wire visits if he’d signed a minor league deal with a Major League team this winter, so it perhaps isn’t surprising that Castillo has opted for the relative security (and a guaranteed salary) of this deal with the Marines.

Though Castillo has pitched in parts of five MLB seasons, that resume consists of his 32 innings in 2025, 38 1/3 innings with the Padres in his 2018 rookie season, and just two innings spread over a single game with the Padres in each of the 2019, 2022, and 2023 campaigns.  Multiple injuries (including a Tommy John surgery) shelved Castillo for almost the entirety of the 2019-21 seasons, and he pitched primarily in the minors with the Padres, Marlins, and Diamondbacks from 2022-24.

While a small sample size of big league work, Castillo’s career 4.11 ERA, 27.1% strikeout rate, and 9.6% walk rate are all respectable for a pitcher with such a journeyman resume.  He also has a 4.21 ERA over 130 1/3 career innings at the Triple-A level.  Control has been an issue for Castillo, but he has always been able to rack up strikeouts and generate grounders.  Castillo doesn’t turn 30 until January, so there’s still plenty of time for the left-hander to explore a future move back to North American baseball depending on how things work out during his Marines tenure.

Kohei Arihara Considering MLB Return

By | at

Former Rangers right-hander Kohei Arihara is interested in returning to MLB, per a report from Yahoo Japan (h/t to Yakyu Cosmopolitan). Arihara is set to become a free agent on December 2. He’s been with the SoftBank Hawks of Nippon Professional Baseball for the past three seasons.

Arihara began his career in NPB, spending six seasons with the Hokkaido Nippon-Ham Fighters. His solid work at Japan’s highest level earned him a two-year, $6.2MM deal with the Rangers in December 2020. Arihara pitched in parts of two seasons for Texas from 2021 to 2022. He struggled to a 6.64 ERA across 10 starts with the Rangers in his first season. The results were even worse the following year, when Arihara posted a 9.45 ERA over five appearances. He was designated for assignment in September 2022 and elected free agency at the end of the year.

The righty’s stateside debut was marred by a serious injury early in the season. The team discovered an aneurysm in Arihara’s shoulder, leading to surgery that sidelined him until September. Arihara was crushed for nine earned runs over 12 innings after coming back from the injury.

Arihara excelled in his return to NPB, putting together three productive seasons with the Hawks. He posted a pristine 2.31 ERA in 17 starts with the team in 2023. Arihara nearly matched that mark across a longer sample the following season, recording a 2.36 ERA over 26 starts on his way to 14 wins. He won another 14 games this past season, though his ERA did creep over 3.00.

The 33-year-old Arihara seems to be past the health issues that plagued his previous MLB stint, tossing at least 175 innings in back-to-back seasons. He’s certainly built some momentum toward a possible return to the big leagues. The Yahoo Japan report noted that the Yomiuri Giants are also interested in Arihara’s services.

Dayan Viciedo Signs With Yokohama DeNA BayStars

By | at

Veteran infielder Dayan Viciedo has signed a contract with the Yokohama DeNA BayStars for the 2026 season, per an announcement from the BayStars.

Viciedo, now 36, is a Cuban slugger who played in parts of five seasons in the majors with the White Sox from 2010 to 2014. Considered to be among the league’s best prospects after hitting well in the Cuban National Series as a teenager before defecting to play in the majors, Viciedo impressed in a 38-game cup of coffee when he hit .308/.321/.519 across 106 plate appearances for the White Sox in 2010. That seemed to portend a promising future, but Viciedo wouldn’t enjoy a full season at the big league level in 2012. In parts of three seasons as a big league regular for the White Sox, he hit just .250/.294/.425 with a wRC+ of 95.

While he did flash consistent 20-homer pop with the bat, Viciedo was held back by a free-swinging approach that led him to walk in just 5.3% of his trips to the plate during his years as a regular. A 95 wRC+ is hardly unplayable at the big league level, but Viciedo primarily played the outfield corners during his time with the White Sox and received poor grades for his fielding on the grass. Given that, it was hardly a surprise when the White Sox cut him loose prior to the 2015 season. He spent 2015 in the A’s and White Sox farm systems before making the jump to NPB’s Chunichi Dragons in 2016.

Viciedo has done quite well for himself overseas. In 1001 NPB games over the years, he’s managed to hit .287/.352/.458 with 141 career homers. Things began to take a turn for the worse for Viciedo in recent years, however, as he began to struggle in Central League play. After difficult back-to-back seasons for the Dragons in 2023 and ’24, Viciedo actually departed Japan and signed with the Mexican League’s Tecolotes de los Dos Laredos. In 38 games for his new club, Viciedo looked like his old self and slashed .276/.359/.462 with eight homers.

That was enough to catch the attention of the BayStars, and he signed with them back in July to finish out the 2025 season in Japan. He hit .259/.322/.383 in 43 Central League games last year and now will return to the BayStars for a full season in 2026 as he looks to re-establish himself in NPB. He was joined by former big leaguers Mike Ford, Tyler Austin, and Yoshi Tsutsugo in the BayStars’ lineup during the 2025 season. While Viciedo played primarily the outfield corners during his time in the majors, he’s primarily been a first baseman in NPB and will likely fill a first base/DH role for the BayStars in 2026.

Jo Hsi Hsu Signs With NPB’s Fukuoka SoftBank Hawks

By | at

Taiwanese right-hander Jo Hsi Hsu has signed with the Fukuoka SoftBank Hawks of Japan’s Nippon Professional Baseball. It’s a three-year deal with incentives worth more than $9.6MM USD. Yihsuan Wang of Yahoo Taiwan relayed the club announcement. Hat tip to CPBL Stats for relaying the details in English.

The 25-year-old righty has turned some heads with his results in the CPBL. He has thrown 305 innings for the Wei Chuan Dragons, including 114 innings in 2025 with a 2.05 earned run average. He struck out 28% of batters faced this year while limiting walks to a tiny 3.3% rate.

It was reported last week that the Dragons would make him available via the posting system and that Hsu was considering a jump to Major League Baseball, though a move to NPB seemed more probable.

A scouting report from Eric Longenhagen and James Fegan of FanGraphs suggested that many MLB clubs would likely view Hsu as a reliever. They then wondered if that would lead him to Japan in an attempt to further prove himself as a capable starter against a higher level of competition.

Hsu’s motivations aren’t known but he will indeed head to Japan. He is still quite young, so perhaps a move to North America will become viable down the road if he puts up good numbers for the Hawks.

Kenta Maeda Signs With NPB’s Rakuten Eagles

By | at

The Tohoku Rakuten Golden Eagles of Japan’s Nippon Professional Baseball announced they’ve signed Kenta Maeda. The 37-year-old righty said in August that he planned to return to his home country next year. A report from Japan’s Sankei Sports indicates he signed a two-year contract.

This will all but officially close the book on Maeda’s career in the major leagues. He pitched in nine MLB seasons, turning in a 4.20 earned run average while coming up a little shy of 1000 innings pitched. Maeda spent the first four seasons of his career with the Dodgers after signing an eight-year deal to join Los Angeles over the 2015-16 offseason. His rookie year was his best in Dodger blue, as he won 16 games and turned in a 3.48 ERA over a career-high 175 2/3 frames. Maeda struggled in the postseason that year but rebounded with 10 2/3 innings of one-run ball in October 2017 to help the Dodgers to a pennant.

L.A. shipped Maeda to Minnesota for Brusdar Graterol and Luke Raley over the 2019-20 offseason. Maeda’s first season in Minnesota was shortened by the truncated schedule but arguably the best of his career. He turned in a 2.70 ERA while averaging more than six innings per appearance over 11 starts, earning a runner-up finish behind Shane Bieber in AL Cy Young voting. Maeda remained in the Twin Cities for another three seasons, though he missed the 2022 campaign rehabbing Tommy John surgery.

The Tigers signed him to a two-year, $24MM free agent deal going into 2024. While it was a sensible bet on Maeda’s strong strikeout and walk profile, his diminishing stuff led to significant home run issues. Maeda was hit hard to the tune of a 6.09 ERA in 2024. He didn’t find any better results early in the ’25 campaign while pitching out of the bullpen, leading the Tigers to release him in early May. That wound up marking the end of his MLB career. Maeda pitched in Triple-A with the Cubs and Yankees, posting a 5.40 ERA across 20 starts through the end of the year.

Maeda returns to Japan, where he starred for the Hiroshima Carp for eight seasons before making the move to MLB. He owns a 2.39 ERA in a little more than 1500 career NPB innings. He’ll be teammates with former big leaguers Luke Voit and Roansy Contreras, each of whom have already signed with the Eagles for the 2026 season.

Blue Jays’ Easton Lucas Granted Release, Expected To Sign Overseas

By | at

The Blue Jays announced Tuesday that they’ve placed left-hander Easton Lucas on unconditional release waivers. That drops their 40-man roster count to 37. Ben Nicholson-Smith of Sportsnet reports that Lucas will sign with a foreign team once he clears waivers (presumably in Japan’s Nippon Professional Baseball or in the Korea Baseball Organization).

Lucas, 29, appeared in six games (five starts) for Toronto this past season. He became a cult hero in April when he rattled off 10 1/3 shutout innings across two starts to begin his Jays tenure — including a game at Fenway Park where he outdueled eventual Cy Young runner-up Garrett Crochet. The good times didn’t last, however. Lucas was torched for eight runs in his next start and wound up surrendering a total of 18 runs in 14 innings following that scoreless stretch.

This was the third season in which Lucas has logged some big league time, though his 24 1/3 frames this year marked a career-high. He’s pitched 42 2/3 innings in the majors and been tagged for an 8.02 earned run average. Lucas has fanned a below-average 19.6% of opponents against a bloated 12.3% walk rate in his limited MLB exposure.

Triple-A has been another story entirely. Lucas has spent parts of three seasons at the top minor league level and, in 162 2/3 innings, pitched to a solid 3.60 ERA. He’s punched out 24.4% of his opponents and logged a more palatable (but still higher-than-average) 10% walk rate. Lucas sits 93-95 mph with his four-seamer and rounds out his four-pitch arsenal with a changeup, slider and more seldom-used cutter.

NPB’s Chiba Lotte Marines Sign Sam Long

By | at

The Chiba Lotte Marines of Nippon Professional Baseball announced that left-hander Sam Long has been signed to a contract for the 2026 season.  Long heads to Japan after five MLB seasons, and after posting a 5.36 ERA over 40 1/3 relief innings for the Royals in 2025.

Long’s top big league campaign was in 2024, when he had a career-best 3.16 ERA and 25% strikeout rate over 42 2/3 innings out of the K.C. bullpen.  Generally a low-strikeout pitcher with pretty ordinary walk rates, Long’s results have tended to ebb and flow along with his batted-ball luck, and he has a 4.65 ERA to show for his 211 career innings in the majors with the Giants, Athletics, and Royals.

Injuries could partially explains his underwhelming results this year, as Long missed over two months of action due to elbow inflammation.  He started to find his form closer to the end of the season, but it wasn’t enough to stop the Royals from outrighting him off their 40-man roster in November, and Long then elected minor league free agency.

The 30-year-old almost surely would’ve had to settle for a minor league contract this winter if he’d stuck to courting MLB teams, so the move to Japan will earn Long some extra money on a guaranteed deal.  He’ll now look for a fresh start to his career and a role with a Marines team that has made the playoffs four times in the last six years, thought they have been unable to advance to the Japan Series.

CPBL’s Wei Chuan Dragons To Post Jo Hsi Hsu

By | at

The Wei Chuan Dragons of Taiwan’s Chinese Professional Baseball League are posting right-hander Jo Hsi Hsu for MLB clubs, as noted by CPBL Stats. Hsu is considering a jump to either MLB or Nippon Professional Baseball in Japan this offseason. Hsu himself told reporters that he’s already visited Japan and had dinner with NPB legend Sadaharu Oh, who now serves as the chief baseball officer for the SoftBank Hawks. According to Taiwanese outlet TSNA, Hsu has also garnered stateside interest from the Dodgers.

CPBL players can be posted for international free agency with the permission of their club after they’ve reached three years of service time. Hsu, 25, is in the midst of that process now and will market himself coming off a 2025 season where he pitched to a sterling 2.05 ERA with a 28.0% strikeout rate across 19 starts and 114 innings of work. That workload is fairly standard for the 119-game CPBL season, but it leaves questions about how well he’d be able to handle the rigors of a 162-game schedule as a starter in the big leagues.

Eric Longenhagen and James Fegan of Fangraphs took a look at Hsu’s profile last month and suggested that it’s “probable” most MLB clubs will view him as a reliever as he was unable to maintain his top velocity throughout even that 19-start campaign in the CPBL this year. Longehagen and Fegan both suggest that Hsu has the talent to be a late-inning set-up man in the majors, and a player headed into his age-25 season who could immediately slot into the back of any bullpen would surely be an attractive piece for teams to consider. With that being said, Longenhagen and Fegan both suggest that Hsu might prefer to first go to Japan to attempt to hone his skills as a starter before making the jump to MLB.

That’s a path that could be attractive for financial reasons. Hsu is young enough that even if he spent two or three years in Japan, he’d be able to come to MLB much younger than the average free agent pitcher. That could set him up for a more lucrative payday, particularly because then all posting fees owed to his the Dragons would be attached to his NPB contract. That would leave MLB teams able to offer Hsu the full amount they believe him to be worth rather than sending a portion of that money overseas to the Dragons. The CPBL posting fee is 20% of the first $25MM a player earns in their MLB contract, 17.5% of the next $25MM, and 15% of any dollars above $50MM. For minor league contracts, the posting fee is equivalent to 25% of the player’s signing bonus.

Beneficial as a stop in NPB might be financially, Hsu certainly wouldn’t be the first player to eschew a larger immediate payday for the opportunity to pitch in the majors sooner. Roki Sasaki opted to be posted last winter, when he wasn’t yet old enough to sign more than a minor league contract, and Shohei Ohtani famously did the same when he first came over to the United States. If Hsu does come stateside, it seems as though the Dodgers have at least some interest in his services. L.A. is hardly a club that’s been shy about making a splash in international markets, and while those efforts have been primarily focused on NPB (Yoshinobu Yamamoto, Sasaki) and KBO (Hyeseong Kim) players in recent offseasons, it wouldn’t be a shock to see them expand their horizons to Taiwan.

It seems silly to call anything about a back-to-back World Series champion disappointing, but the Dodgers made a big investment in the back of their bullpen by picking up Tanner Scott and Kirby Yates last winter that ultimately did not pan out. Adding an arm like Hsu to the fold alongside Scott could give L.A. some additional firepower in the bullpen to help make up for the loss of Evan Phillips, who underwent Tommy John surgery in June and was non-tendered this past week.

Of course, the Dodgers are hardly the only team who could have interest in Hsu’s services. International relief signings have typically come in at a fairly affordable price tag that could make him an interesting target for virtually any club searching for bullpen help this winter. Woo-Suk Go (two years, $4.5MM), Yuki Matsui (five years, $28MM), and Shintaro Fujinami (one year, $3.5MM) are all players who signed from the international market as relievers in recent years, and none came with the typical price tag associated with late-inning relievers already established in MLB.

NPB’s Hiroshima Carp Sign Freddy Tarnok, Re-Sign Elehuris Montero

By | at

11:46AM: Tarnok will earn $1.5MM in guaranteed money, MLB Trade Rumors’ Steve Adams reports, with close to $500K in incentive bonuses attached to the contract.

10:12AM: The Hiroshima Carp have signed right-hander Freddy Tarnok and re-signed infielder Elehuris Montero to contracts for the 2026 season, the team announced.  The terms of Tarnok’s deal aren’t known, but Montero will receive $1.25MM (broken down as a $750K salary and $500K signing bonus) plus incentives.

Tarnok has appeared in 11 games over parts of three Major League seasons, with five of those games coming with the Marlins in 2025.  Signed to a minor league deal last offseason, Tarnok had his contract selected to the 40-man and active rosters in June, and he posted a 2.45 ERA over 7 1/3 innings amidst several options back and forth from Triple-A and the majors.  The righty struck out 35.7% of batters during his small sample size of MLB work, but also had a 14.3% walk rate.

To some extent, Tarnok’s increasingly shaky control and his ability to miss bats has been the story of his minor league career, which consists of stops in the farm systems of the Marlins, Phillies, A’s, and Braves.  Tarnok has a 4.08 ERA over 161 innings at the Triple-A level, starting 28 of those 65 games as he has been used more frequently as a reliever in recent years.

The move to Japan might well give Tarnok another chance to re-establish himself as a starting pitcher.  Tarnok is just two days away from celebrating his 27th birthday, so he’s plenty young enough to post some good numbers with the Carp and perhaps get himself back onto the radar for big league teams as early as next winter.  If nothing else, signing in NPB will land Tarnok some guaranteed money, whereas he would’ve very likely had to settle for another minor league deal from a Major League team.

Montero hit .228/.277/.387 over 739 plate appearances with the Rockies from 2022-24, and is perhaps best known as part of the trade package the Cardinals sent to Colorado for Nolan Arenado prior to the 2021 season.  Montero’s first season in Hiroshima saw the 27-year-old hit .255/.301/.391 with nine home runs over 396 PA as the Carp’s regular first baseman.  While not huge numbers for a first base bat, Montero seems to have done enough for the Carp to pursue a reunion.
