Merrill Kelly is a Bronze 70 OVR Starting Pitcher card for the Diamondbacks, 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, Merrill Kelly works with a 5-pitch arsenal led by a 92 mph 4-Seam Fastball and a 92 mph Sinker. His pitching ratings include 81 Velocity, 66 Control, and 89 Break. The profile favors a movement-heavy arsenal built to miss bats.

DiamondOps grades each pitch in Merrill Kelly's arsenal: 4-Seam Fastball (S), Cutter (S), Sinker (S), Circle Change (A), and Curveball (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 81 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, Merrill Kelly currently buys for about 98 stubs, with sell orders near 25 stubs. Over the past 7 days the buy price has climbed roughly 180%. Flipping at current buy and sell prices nets roughly 61 stubs, about a 235% return. DiamondOps flags the card as currently overpriced.

OpScore is DiamondOps' composite rating of a card's in-game performance value. Merrill Kelly earns an OpScore of 59.4 on Legend difficulty, ranking #1897 among all cards and #412 among Starting Pitchers.
