Joe Rock is a Common 63 OVR Starting Pitcher card for the White Sox, part of the Live set in MLB The Show's Diamond Dynasty. He throws left-handed. The card was added to Diamond Dynasty in April 2026.

On the mound, Joe Rock works with a 4-pitch arsenal led by a 94 mph 4-Seam Fastball and a 93 mph Sinker. His pitching ratings include 89 Velocity, 56 Control, and 86 Break. The profile favors a movement-heavy arsenal built to miss bats.

DiamondOps grades each pitch in Joe Rock's arsenal: Slider (S), Sinker (S), 4-Seam Fastball (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 Sinker off the 4-Seam Fastball, so the two share a release look. Velocity works against the card here — its 89 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, Joe Rock currently buys for about 13 stubs, with sell orders near 0 stubs. Over the past 7 days the buy price has fallen roughly 24%. Its quick-sell value of 5 stubs sits at or above the sell price, making it quick-sell viable. DiamondOps currently rates the card a buy at this price.
