The 2025-26 offseason features another strong class of Japanese free agents, with right-handed starting pitcher Tatsuya Imai leading the way alongside infielders Munetaka Murakami and Kazuma Okamoto. The 27-year-old Imai projects as a mid-rotation starter and is expected to command a contract exceeding nine figures from Major League Baseball teams.

Imai has shown significant improvement in his control over recent seasons. His walk rate decreased from 5.1 BB/9 in 2022 to 2.5 in 2025, according to ESPN's analysis.

The 5-foot-11 right-hander features a fastball that sits 93-97 mph and touches 99. His splitter grades as above-average, while his slider—which moves arm-side rather than glove-side—generated a 45% miss rate and .212 xwOBA last season. His unconventional approach mirrors that of MLB pitcher Trey Yesavage.

Teams value Imai's ability to make adjustments and his youth relative to the free agent class. He doesn't require a qualifying offer compensation pick, making him attractive to most organizations.

Industry projections estimate an all-in cost of $157 million over six years, including the posting fee to his NPB club. That figure could prove conservative given market demand.

The New York Mets, San Francisco Giants and New York Yankees are among high-spending teams showing interest. Lower-spending clubs like the Pittsburgh Pirates and Miami Marlins are also expected to pursue starting pitching this offseason.

Scouts note that Imai's fastball location needs refinement, as his current pitch placement is too center-cut. His fastball shape would perform better at the top of the strike zone.
