Shintaro Fujinami Signs With NPB’s Yokohama DeNA BayStars
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
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
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
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
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
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
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.
Oscar Gonzalez Signs Two-Year Deal With NPB’s Golden Eagles
May 22: Gonzalez has officially signed a two-year deal with the Golden Eagles, per Jon Heyman of the New York Post. The MAS+ client will be paid $2MM through the 2026 season.
May 19, 7:50pm: Gonzalez has an agreement with the Tohoku Rakuten Golden Eagles, reports Francys Romero.
3:44pm: The Padres have placed outfielder Oscar Gonzalez on unconditional release waivers in order to allow him to pursue an opportunity in Japan’s Nippon Professional Baseball, reports Dennis Lin of The Athletic. With Gonzalez being granted his release, San Diego is down to 37 players on its 40-man roster.
Gonzalez, 27, signed a minor league deal with the Friars back in November. He’s appeared in 21 big league games and tallied 61 plate appearances while hitting .220/.246/.237. The Dominican-born slugger showed promise during his 2022 rookie campaign with the Guardians, bursting onto the scene with a .296/.327/.461 batting line and 11 homers in 382 plate appearances, but he’s hit just .216/.241/.293 in 241 MLB plate appearances since that time.
Gonzalez posted league-average offense with the Guards’ Triple-A club in 2023 and was a slight bit better than average in the Yankees’ system last year, but he’s been on a blistering tear in El Paso this season. It’s only 57 plate appearances, but the righty-swinging corner outfielder touts a .333/.368/.704 line with the Chihuahuas. The Pacific Coast League is notoriously hitter-friendly, but he’s still been 54% better than average in that time and now touts a career .285/.321/.502 output in 1212 Triple-A plate appearances spread across parts of five seasons.
The Padres have had some of the worst production in baseball out of left field in 2025, hitting just .190/.236/.268 as a whole from that position. The resulting 44 wRC+ (indicating they’ve been 56% worse than average at the plate) ranks 28th in MLB. The bulk of Gonzalez’s plate appearances — 42 of the 61 — came as a left fielder. He’s combined with Jason Heyward, Brandon Lockridge, Tirso Ornelas, Gavin Sheets, Jose Iglesias and Connor Joe to compile that floundering left field line at the plate.
As it stands, left field seems likely to be an area of focus for the Padres when the deadline rolls around. The 27-18 Padres, sitting just one game behind the Dodgers in the NL West, look like surefire buyers. The farm system doesn’t have much in the way of immediate help to offer. Most of the outfielders in Triple-A are journeymen types who aren’t on the 40-man roster. Names like Tim Locastro, Forrest Wall, Mike Brosseau and Bryce Johnson have all logged time there with El Paso.
Twenty-six-year-old Yonathan Perlaza, a former Cubs farmhand who signed a minor league deal with the Padres after a nice performance in the KBO last year, is hitting .293/.335/.463 — but that’s about 8% worse than average in the PCL’s supercharged offensive atmosphere and he’s fanned in 28% of his plate appearances. It’s a dire situation, so any of those Triple-A names could get a look at some point — particularly with three vacancies on the 40-man roster. In general, the Padres’ system is lacking in impact outfielders after years of aggressive dealing on the trade market.
Jay Jackson To Retire
After a professional career that spanned 17 years, veteran right-hander Jay Jackson is hanging up his glove. Robert Murray of FanSided reported this afternoon that Jackson is retiring from his playing career, adding that the 37-year-old hopes to have a second act in baseball, whether that comes by working for a team or in broadcasting.
Jackson was selected by the Cubs in the ninth-round of the 2008 MLB draft and made his pro debut later the summer at 20 years old. A fringe top-100 prospect entering the 2010 season after he pitched to a 2.98 ERA in 24 starts across three levels of the Chicago farm system, Jackson spent the next three seasons struggling at the Triple-A level without breaking into the majors. He was eventually released by the Cubs in early 2013 and bounced between the Marlins, Pirates, and Brewers before eventually landing with the Padres prior to the 2015 season. In San Diego, the right-hander moved to a full-time bullpen role and dominated the Double- and Triple-A levels, earning the opportunity to pitch in the majors for the first time in his career.
Jackson’s first big league cup of coffee did not go especially well, as he surrendered three runs in 4 1/3 innings across six appearances. Even so, the opportunity was enough to get the righty noticed by the Hiroshima Carp of Japan’s Nippon Professional Baseball. He pitched for the Carp for three seasons, from 2016 to 2018, and put together an impressive resume with a sterling 2.11 ERA and a 26.9% strikeout rate in 175 NPB innings. That work earned him his second big league opportunity, as he returned to the Brewers organization and pitched to a 4.45 ERA across 30 1/3 innings of work in 2019, but it was only after a second sojourn to Japan (this time as a member of the Chiba Lotte Marines) in 2020 that Jackson was able to stick in the majors.
After signing with the Giants in 2021 for his age-33 season, Jackson enjoyed a late-career stretch of success in the majors. Though he pitched just 52 2/3 innings at the big league level for San Francisco, Atlanta, and Toronto from 2021 to 2023, Jackson posted an excellent 2.73 ERA across those 50 appearances and struck out 26.5% of his opponents. That was enough to earn Jackson a look from the Twins last year in his age-36 season, though he struggled badly with a 7.52 ERA across 20 appearances before being released by Minnesota last year. Jackson initially signed with the Mexican League’s Bravos de Leon earlier this month in an effort to continue his playing career, but evidently has now decided to wrap up his days as a player instead.
Overall, Jackson pitched to a lifetime 4.43 ERA (97 ERA+) with a 4.47 FIP across 113 2/3 major league innings, with a 7-4 record and 136 strikeouts in 104 career games. That’s in addition to his excellent years in Japan, where he posted a 2.16 ERA and struck out 204 batters in 183 NPB innings. We at MLB Trade Rumors congratulate Jackson on his nearly two decades of work in baseball and wish him all the best in whatever comes next.
NPB’s Tokyo Yakult Swallows Sign Pedro Avila
The Tokyo Yakult Swallows of Nippon Professional Baseball have signed right-hander Pedro Avila, according to multiple reports out of Japan. Avila elected free agency in January rather than accept an outright assignment to the Guardians’ Triple-A team.
After posting a 2.70 ERA over the small sample size of 13 1/3 big league innings with the Padres from 2019-22, Avila received a larger role in the form of 50 1/3 frames in 2023. An excellent 58.8% grounder rate and a solid 24.5% strikeout rate helped Avila overcome a middling 11.4% walk rate, but a shaky start early in the 2024 season led the Padres to designate the righty for assignment in April.
The Guardians picked Avila up in a cash transaction a few days after, and Avila went on to become a workhorse within the elite Cleveland bullpen. Beyond logging 74 2/3 innings over 50 appearances, Avila also had a 3.25 ERA during his time with the Guards, though his K% slightly declined from 2023 and his grounder rate dropped to 45% (though he also cut back on the walks). He added to that solid performance with four shutout innings in the playoffs, and he was the winning pitcher in Cleveland’s only victory of the ALCS, a 7-5 walkoff over the Yankees in Game 3.
Such production would normally have given Avila a clear ticket to a roster spot on most teams, but he is out of minor league options, and the Guardians are so deep in relief pitching that Avila became expendable. As it turned out, the Guards designated Avila to create roster space when they signed another reliever, former Diamondbacks closer Paul Sewald.
Avila’s out-of-options status might have left him in a crunch when trying to break camp with another MLB team this spring, so he’ll now head to Japan for more of a guaranteed role with the Swallows. This is the first time the 28-year-old Avila has pitched professionally outside of affiliated baseball, apart from five stints in the Venezuelan Winter League.
