Mitch Keller

Mitch Keller is a Gold 83 OVR Starting Pitcher card for the Pirates, part of the All-Star 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, Mitch Keller works with a 5-pitch arsenal led by a 95 mph 4-Seam Fastball and a 94 mph Sinker. His pitching ratings include 90 Velocity, 0 Control, and 99 Break. The profile favors a movement-heavy arsenal built to miss bats.

DiamondOps grades each pitch in Mitch Keller's arsenal: 4-Seam Fastball (S), Cutter (S), Sinker (S), Sweeper (S), and Curveball (B). 4 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 Sinker, so the two share a release look. Velocity works against the card here — its 90 mph Sinker 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.

Mitch Keller is not currently traded on the open Diamond Dynasty market — cards like this are typically earned through programs or collections rather than bought with stubs.

OpScore is DiamondOps' composite rating of a card's in-game performance value. Mitch Keller earns an OpScore of 56.2 on Legend difficulty, ranking #2648 among all cards and #537 among Starting Pitchers.
