Roy Oswalt

Roy Oswalt is a Gold 83 OVR Starting Pitcher card for the Astros, part of the 2nd Half Heroes 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, Roy Oswalt works with a 5-pitch arsenal led by a 93 mph 4-Seam Fastball and a 92 mph Sinker. His pitching ratings include 82 Velocity, 0 Control, and 96 Break. The profile favors a movement-heavy arsenal built to miss bats.

DiamondOps grades each pitch in Roy Oswalt's arsenal: 4-Seam Fastball (S), Sinker (S), Cutter (S), Circle Change (A), and 12-6 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 82 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.

Roy Oswalt 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. Roy Oswalt earns an OpScore of 53.7 on Legend difficulty, ranking #2880 among all cards and #568 among Starting Pitchers.
