Roy Oswalt is a Red Diamond 99 OVR Starting Pitcher card for the Phillies, part of the Finest set in MLB The Show's Diamond Dynasty. He throws right-handed. The card was added to Diamond Dynasty in August 2026.

On the mound, Roy Oswalt works with a 5-pitch arsenal led by a 93 mph 4-Seam Fastball and a 93 mph Sinker. His pitching ratings include 86 Velocity, 94 Control, and 99 Break. The profile favors a balanced mix of command and movement.

DiamondOps grades each pitch in Roy Oswalt's arsenal: Slider (S), 4-Seam Fastball (S), Sinker (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 86 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.

On the Diamond Dynasty market, Roy Oswalt currently buys for about 6,219 stubs, with sell orders near 5,222 stubs. Over the past 7 days the buy price has fallen roughly 12%. Flipping at current buy and sell prices nets roughly 373 stubs, about a 7% return. DiamondOps suggests waiting for a better entry point.

OpScore is DiamondOps' composite rating of a card's in-game performance value. Roy Oswalt earns an OpScore of 85.7 on Legend difficulty, ranking #721 among all cards and #134 among Starting Pitchers.
