51. Astros RHP Tatsuya Imai | 27 | NPB | 2026

Imai has been dominant in Japan since 2022 when he was 24 years old with a 2.04 ERA and 1.11 WHIP. 2025 was his best season yet. He recorded a 1.92 ERA and 0.89 WHIP, representing a big leap forward in command. His walk rate of 2.5 per nine innings was a full walk better than his previous career-best mark of 3.6. Imai generates these results on the back of a fastball-slider combination against righties with a splitter against lefties. Houston’s still having a lot of success with pitchers, and I’m betting that continues with Imai. You can move him up this list in deeper leagues or win-now windows.
