The Seibu Lions announced they will post right-handed pitcher Kaima Taira, clearing the way for him to pursue a move to Major League Baseball, according to Bleacher Report. The announcement makes Taira, who has spent his career with Seibu in Japan’s top professional league, eligible to negotiate with any interested MLB club.
Taira posted a 1.36 ERA in the 2025 season in Japan’s top professional league and recorded 31 saves for the Lions. His career record stands at 37-24.
Terms Of The Move
The posting makes Taira available to MLB organizations through the system that governs transfers of players under contract to Japanese clubs. No posting fee, negotiation window or other financial terms have been disclosed.
Taira stated his ambitions: “As a pitcher, my goal is to win a Cy Young award. And I’d like to pitch in the World Series as well.”
Why It Matters For Interested Teams
Two teams have already scouted Taira. The New York Yankees have shown interest, though he would likely slot in as a bullpen option given New York’s expected starting rotation. The San Francisco Giants have also scouted him as they look to reshape their roster coming off a 65-97 season.
Taira’s versatility gives him flexibility that could appeal to teams with different roster needs. Teams chasing rotation depth and those looking to retool the bullpen could each pursue him.
What’s Next
No timetable for when MLB negotiations will begin or conclude has been announced. The posting confirmed by Seibu opens the door for teams to engage with Taira, but further details on the negotiation window, posting fee or additional interested clubs have not been released.
