MLB’s winter meetings begin Monday in Orlando, and unsurprisingly, the New York Mets are right at the center of the rumor mill.
In an article published by ESPN on Friday, insiders Jeff Passan and Buster Olney shared the latest intel on the top names available via trade and free agency. Among the players linked to the Mets was starting pitcher Tatsuya Imai, who was posted by the Saitama Seibu Lions of Nippon Professional Baseball on Nov. 19.
“Japanese right-hander Tatsuya Imai could wind up with a big-market team on the East Coast,” Passan wrote. “The New York Yankees — with Gerrit Cole and Carlos Rodon expected to miss the start of the season — New York Mets and Philadelphia are reasonable landing spots.”

Imai, 27, went 10-5 with a 1.92 ERA and 0.89 WHIP over 163.2 innings this past season for the Lions. He struck out 178 batters, walked 45, and allowed only six home runs while earning his second consecutive All-Star appearance. He also pitched eight innings of a combined no-hitter on April 18 and tallied 17 strikeouts on June 17, breaking Daisuke Matsuzaka’s previous team record.
In eight seasons with Seibu, Imai has posted a 3.15 ERA, with his ERAs over the past three years largely improving alongside better strikeout and walk rates. The 5-foot-11 right-hander generally relies on a fastball that can reach 99 mph and his “backwards” slider, but he also has a changeup, a splitter, and began incorporating a sinker late in the season.
Tatsuya Imai looks every bit like an impact arm that MLB teams will be eager to pursue.

MLB Network’s Jon Morosi wrote in early November that Imai’s profile is similar to, or perhaps even slightly better than, Kodai Senga, who left NPB to sign a five-year, $75 million deal with the Mets in December 2022. His low right-handed arm slot, velocity, and pitch movement have also drawn some comparisons to Luis Castillo of the Seattle Mariners.

According to Jon Heyman of the New York Post, Imai’s camp could schedule in-person visits with interested teams following next week’s winter meetings — that is, of course, if he has not already agreed to a deal by that point. His 45-day negotiating window ends Jan. 2 at 5 p.m. ET.
Under MLB’s posting agreement with NPB, the posting fee would be 20% of the first $25 million of a major league contract, including earned bonuses and options. The percentage drops to 17.5% of the next $25 million and 15% of any amount over $50 million. There would also be a supplemental fee of 15% of any earned bonuses, salary escalators, and exercised options.
