Jason Adam is a Silver 79 OVR Relief Pitcher card for the Free Agents, 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, Jason Adam works with a 4-pitch arsenal led by a 95 mph 4-Seam Fastball and a 88 mph Circle Change. His pitching ratings include 76 Velocity, 81 Control, and 94 Break. The profile favors a movement-heavy arsenal built to miss bats.

DiamondOps grades each pitch in Jason Adam's arsenal: Slider (S), 4-Seam Fastball (S), Sweeper (S), and Circle Change (A). 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 Slider off the 4-Seam Fastball, so the two share a release look. Velocity works against the card here — its 76 mph 4-Seam Fastball 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, Jason Adam currently buys for about 196 stubs, with sell orders near 0 stubs. Over the past 7 days the buy price has climbed roughly 17%. Its quick-sell value of 150 stubs sits at or above the sell price, making it quick-sell viable. DiamondOps suggests waiting for a better entry point.

OpScore is DiamondOps' composite rating of a card's in-game performance value. Jason Adam earns an OpScore of 70.8 on Legend difficulty, ranking #1269 among all cards and #93 among Relief Pitchers.
