Seibu Lions pitcher Tatsuya Imai just isn’t obtainable to main league groups simply but. That may change on Nov. 19 when he’s formally posted, giving groups 45 days to signal Imai; in any other case, he’ll pitch for the Lions in 2026.
Ought to Imai return to Japan, it won’t be resulting from an absence of main league curiosity. He’s considered one of many high free agent pitchers obtainable throughout the 2025-26 offseason and will command a wholesome wage. He posted a powerful 1.92 ERA and a 0.892 WHiP over 163.2 innings, putting out 178 batters with 45 walks. Whereas Nippon Skilled Baseball is skewed towards pitching, Imai was sixth in NPB in ERA and second in WHiP.Â
The 27-year-old is an intriguing choice for any main league crew. He has a five-pitch arsenal led by a mid-90s fastball that may strategy triple digits and a plus slider. Imai rounds out the arsenal with a splitter, a changeup and may alter the form of his slider to have it play extra like a curveball. He has steadily improved his capacity to command his arsenal, enhancing his stroll charge from 7.6 BB/9 with the Lions in 2020 to 2.5 BB/9 in 2025. It’s thought that Imai may attain one other stage with tweaks to his supply, with mechanical changes permitting him to completely attain his potential.
There are a couple of query marks. Imai is smaller than the standard beginning pitcher at 5-foot-11 and 154 kilos. It’s truthful to marvel how he’ll maintain as much as the pains of a significant league season. Likewise, as MLB has a bigger ball, he could face an extended adjustment interval. Nevertheless, his potential and arsenal make him properly definitely worth the threat.
Imai ought to generate loads of curiosity as soon as he formally turns into obtainable. Let’s check out three potential touchdown spots for the Japanese righty.
The Dodgers don’t particularly want Imai. Their rotation is seemingly set with Shohei Ohtani, Yoshinobu Yamamoto, Blake Snell and Tyler Glasnow. Common supervisor Brandon Gomes stated that Roki Sasaki, who excelled in aid throughout the postseason, is a part of their plans for the rotation in 2026. The likes of Gavin Stone, Emmett Sheehan, Landon Knack and River Ryan may battle Sasaki for the fifth starter spot.
Nevertheless, none of that group is a given to stay within the rotation. Imai could come along with his personal query marks, however he could be among the best fifth starters in baseball within the Dodgers’ projected rotation. Likewise, the Dodgers’ pitching depth could be a determined power, offering an avenue for potential trades to spherical out the roster. Because the final two high Japanese pitchers to be posted landed in Los Angeles (Yamamoto and Sasaki), the Dodgers can’t be counted out for Imai.
There isn’t any query that the Mets must overhaul their rotation. Accidents and ineffectiveness with their starters torpedoed their second half because the rotation posted a 5.31 ERA, twenty seventh within the majors. A few of these enhancements ought to come from inside, as pitchers Sean Manaea, Kodai Senga and Clay Holmes are anticipated to enhance from final 12 months. Likewise, younger starters comparable to Brandon Sproat, Jonah Tong and Nolan McLean ought to play a component within the Mets’ 2026 plans.
Nevertheless, there are many questions round every of these choices. Including one other starter or two would supply the Mets with extra of a margin for error and higher depth within the wake of accidents or disappointing performances. Imai is considered having a profile much like Senga, giving the Mets a level of familiarity along with his arsenal. Including Imai would give the Mets an alternative choice with upside for the rotation as they appear to return to the postseason.
The Padres’ rotation is in a state of flux heading into the offseason. Starters Dylan Stop and Michael King are free brokers, leaving a pair of gaping holes on the pitching employees. Yu Darvish will miss the whole 2026 season after present process elbow surgical procedure and will likely be 40 years outdated when he returns. Though the Padres have a number of thrilling pitching prospects of their system, they’re nonetheless years away from making an impression on the main league stage.
Including Imai would give the Padres a powerful duo atop the rotation as he would possible slot behind Nick Pivetta because the second starter. Imai’s relative youth would even be a bonus to a crew that’s seeking to construct a sustainable contender. Imai might be the Padres entrance of the rotation starter heading into the following decade, main the crew as they appear to dethrone the Dodgers within the NL West.
