Tatsuya Imai is a Bronze 69 OVR Relief Pitcher card for the Astros, part of the Live set in MLB The Show's Diamond Dynasty. He throws right-handed. The card was added to Diamond Dynasty in April 2026.

On the mound, Tatsuya Imai works with a 5-pitch arsenal led by a 95 mph 4-Seam Fastball and a 86 mph Slider. His pitching ratings include 78 Velocity, 46 Control, and 79 Break. The profile favors a movement-heavy arsenal built to miss bats.

DiamondOps grades each pitch in Tatsuya Imai's arsenal: Slider (S), 4-Seam Fastball (S), Circle Change (A), Splitter (A), and Curveball (B). 2 of them grade S-tier, which is what separates a genuine out-pitch mix from a deep-but-flat arsenal. Its strongest tunnel pairing is the 4-Seam Fastball off the Slider, so the two share a release look. Velocity works against the card here — its 78 mph 4-Seam Fastball is slow enough to cost it in the arsenal score. Arsenal grades are the same at every difficulty — unlike a hitter's OpScore, a pitch mix does not re-weight as you climb.
