The clock is ticking for Tatsuya Imai, the Japanese pitching sensation, as the deadline to sign with an MLB team looms large. Despite being one of Nippon Professional Baseball's top arms, Imai has yet to receive a formal offer, even as multiple teams like the New York Mets, Chicago Cubs, and Boston Red Sox have been linked to the 27-year-old. Represented by agent Scott Boras, Imai has already made headlines by publicly ruling out the Los Angeles Dodgers.

Why it matters

Imai may not have the same name recognition as other Japanese stars, but his impressive NPB stats and potential to be a solid mid-rotation starter make him an intriguing target for MLB teams looking to bolster their pitching. However, with proven starters also on the market, Imai's value and risk factor are being closely evaluated.

The details

Imai has a career 3.15 ERA in 159 NPB appearances and posted a standout 1.92 ERA in 2025. Teams like the Red Sox, who have already made moves to strengthen their rotation, see Imai as a potential missing piece. But the lack of a formal offer so far suggests MLB teams are still weighing the risks and rewards of signing the Japanese ace.

  • The deadline for Imai to sign with an MLB team is looming.
  • Imai recently told Udo Times that 'There aren't many concrete options on the table yet.'
