Griffin Jax is a Diamond 88 OVR Relief Pitcher card for the Twins, part of the Contributor 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, Griffin Jax works with a 5-pitch arsenal led by a 97 mph 4-Seam Fastball and a 95 mph Sinker. His pitching ratings include 99 Velocity, 0 Control, and 97 Break. The profile favors a movement-heavy arsenal built to miss bats.

DiamondOps grades each pitch in Griffin Jax's arsenal: Sweeper (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. Its 99 mph Sinker adds a velocity bonus on top. 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, Griffin Jax currently buys for about 4,499 stubs, with sell orders near 3,002 stubs. Over the past 7 days the buy price has climbed roughly 44%. Flipping at current buy and sell prices nets roughly 1,045 stubs, about a 35% return. DiamondOps flags the card as currently overpriced.
