The New York Mets have already had eyes on Kaima Taira, and now the right-hander is officially on the market.
A source told FanSided that the Mets were among several clubs to scout Taira in Japan this past season. On Friday, it was announced that the Seibu Lions will post him to MLB this offseason, putting him on track to become one of the more sought-after pitchers in free agency.
The posting window is expected to open in early November, and international players will have 45 days to reach a deal with a major league team. If Taira does not sign by Dec. 1, when the lockout is expected to begin, that clock will stop until a new collective bargaining agreement is in place.
Inside the Mets’ view of Taira, the appeal starts with the arm. People in the organization believe he has a good arm and a feel to pitch.
The question is how he fits physically and role-wise. At 5'8 and 209 pounds, he is not a big right-hander, and there has been a “mixed bag” assessment on whether he projects best as a starter or a reliever.
What is clear is that his stuff plays: his velocity sits in the mid-90s and can climb close to triple digits.
That versatility matters for a Mets team that needs help in both places. New York is looking for multiple starters this winter, and bullpen depth would help too.
Taira could fit either lane. He would give the Mets another arm to pair with Tarik Skubal and support their young trio of Nolan McLean, Christian Scott and Zac Thornton in the rotation.
If he ends up in the bullpen, he would offer manager Andy Green a high-leverage option late in games.
The Mets were far from alone in monitoring him. The Yankees, Cubs, Mariners, Rangers, Angels, Tigers, Padres, White Sox, Blue Jays and Giants are also known to have scouted the right-hander.
There’s a reason so many teams took notice. Taira turns 27 next month and put together a standout 2026 season, going 12-5 with a 1.36 ERA, a 0.96 WHIP and 141 strikeouts in 23 appearances spanning 146 innings. His ERA led the NPB.
Taira’s career path has bounced around between the rotation and the bullpen. He spent his first five seasons as a reliever, then moved into starting, then returned to relief for two more seasons before 2026.
In 2025, he worked out of the Seibu bullpen, saved 31 games and posted a 1.71 ERA. And he brings a full mix to the table, with a fastball, cutter, changeup, sweeper and splitter.

Bo Bichette Just Forced An Early Mets Offseason Decision
Bo Bichettes expected decision to stay with the Mets for the 2027 season gives the front office an early bit of clarity in what could become a tricky offseason. After a slow start, Bichette found his footing over the second half and finished with a .260 batting average, 18 home runs and 1.9 fWAR, enough production to make the opt-in feel like a sensible move for both player and team.
For the Mets, the bigger takeaway is the timing. With next season already carrying plenty of uncertainty and a looming lockout in the background, Bichette choosing the security of $42 million helps shape the clubs financial planning now rather than later. It also leaves the front office with one less variable to juggle as it tries to map out a roster that could look very different by the time spring training arrives. [Read more 🡒]
Mets Rotation Plans Just Got More Interesting For One Big Reason
Michael Kings decision to decline his player option and head back into free agency adds another name to a Mets offseason market that already figures to be heavy on starting pitching. New York is expected to shop for rotation help, and King fits the profile of a pitcher who could appeal if the club wants to deepen the staff around Nolan McLean and raise the ceiling of the group.
Kings appeal is obvious after a strong 2026 season and a postseason that only strengthened his case. For a Mets team trying to stabilize and improve the rotation, his availability gives the front office another established arm to consider, even if the eventual bidding could make the pursuit more complicated than the fit itself.

Mets Just Made Another Low-Risk Bet Fans Will Want To Track
The Mets added another depth piece Wednesday, claiming Kyren Paris off waivers from the Angels and making room by designating Cristian Pache for assignment. It is the sort of move that barely registers on a busy transaction wire, but it fits the way front offices keep chipping away at the edges of a roster, looking for a younger player with a little more upside than his current resume suggests.
Paris was once a second-round pick with plenty of early intrigue, but injuries and uneven production have slowed that momentum, and his big-league track record has been limited. He has also had to navigate position changes and recent minor league assignments, which makes this exactly the kind of low-cost experiment teams are willing to try when they still believe there might be something worth unlocking.
