Zac Gallen

Zac Gallen is a Diamond 91 OVR Starting Pitcher card for the Diamondbacks, part of the Mexico City 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, Zac Gallen works with a 5-pitch arsenal led by a 94 mph 4-Seam Fastball and a 94 mph Sinker. His pitching ratings include 90 Velocity, 80 Control, and 80 Break. The profile favors a balanced mix of command and movement. Notable quirks include Stopper and Break Outlier from a total of 4 quirks.

DiamondOps grades each pitch in Zac Gallen's arsenal: Slider (S), 4-Seam Fastball (S), Sinker (S), Circle Change (A), and Knuckle-curve (B). 3 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.

Zac Gallen 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. Zac Gallen earns an OpScore of 86.5 on Legend difficulty, ranking #1091 among all cards and #210 among Starting Pitchers.
