MLB Free Agency has officially begun, and once again, Japanese players from NPB are stirring the conversation. In recent offseasons, stars like Yoshinobu Yamamoto and Roki Sasaki have shown how international arms can reshape the market overnight. Now, another name is joining that elite list. Tatsuya Imai is coming to Major League Baseball, and the buzz is already deafening. Known for a fastball that touches 99 mph, Imai enters MLB Free Agency as one of the most intriguing names on the market, a potential top-three pitcher alongside Framber Valdez and Dylan Cease.

According to insider Jon Heyman, the Seibu Lions confirmed plans to post the 26-year-old right-hander this offseason, officially launching Tatsuya Imai MLB hype into full swing. His arrival adds an international twist to what was already shaping up to be a fierce bidding war.

Scouts describe Imai as an explosive yet composed pitcher, a rare mix of power and polish that immediately draws MLB attention. He relies heavily on a mid-to-high-90s fastball and a sharp breaking slider, both of which generate strong swing-and-miss numbers. His ability to command those two pitches, paired with consistent strikeout rates in Japan’s Pacific League, makes him a legitimate rotation anchor for any contender willing to invest.

If Imai’s posting unfolds as expected, teams like the Dodgers, Yankees, and Red Sox could enter the mix. But don’t count out smaller-market franchises desperate for an ace to lift their rotation. Executives see shades of Kodai Senga’s jump to the Mets, a pitcher who adjusted quickly and reshaped expectations for NPB imports. Imai’s mechanics are smooth, his workload is stable, and his competitive edge is undeniable.

For Valdez and Cease, his emergence changes the market dynamics. Clubs with pitching needs now have another elite arm to pursue, driving both excitement and leverage across the board. Each negotiation from here on out will orbit around three names, Valdez, Cease, and Imai, all capable of tilting the postseason balance next year.

The question that lingers under the stadium lights is the one fans love most: which team will take the leap and bring Tatsuya Imai’s 99-mph fastball to the majors?
