Seibu Lions Post Ace Tatsuya Imai, Opening 45-Day MLB Negotiation Window

Multiple big-market clubs are lining up during the GM Meetings to pursue the 27-year-old right-hander.

Overview

  • Tatsuya Imai has been posted by the Seibu Lions, giving him 45 days to reach an MLB deal under the posting agreement.
  • Reporting places the Yankees among the expected frontrunners, with the Mets, Dodgers, Giants, Red Sox and others also linked to the pursuit.
  • Imai is coming off a dominant 2025 with a 1.92 ERA and 178 strikeouts in 163.2 innings, and some outlets rank him among the top starters available.
  • The Tokyo Yakult Swallows already posted slugger Munetaka Murakami, further intensifying this offseason’s NPB-to-MLB market.
  • With Tarik Skubal signaling he wants to remain in Detroit, the Mets are exploring alternatives such as Framber Valdez and Imai, and a USA Today report indicates they could target two front-line starters.
