Ray Kerr

Ray Kerr is a Common 59 OVR Relief Pitcher card for the Braves, part of the Live set in MLB The Show's Diamond Dynasty. He throws left-handed. The card was added to Diamond Dynasty in September 2026.

On the mound, Ray Kerr works with a 5-pitch arsenal led by a 95 mph 4-Seam Fastball and a 93 mph Sinker. His pitching ratings include 88 Velocity, 41 Control, and 76 Break. The profile favors a movement-heavy arsenal built to miss bats.

DiamondOps grades each pitch in Ray Kerr's arsenal: 4-Seam Fastball (S), Sinker (S), Cutter (S), Splitter (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 88 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, Ray Kerr currently buys for about 488 stubs, with sell orders near 22 stubs. Over the past 6 days the buy price has fallen roughly 45%. Flipping at current buy and sell prices nets roughly 415 stubs, about a 1804% return. DiamondOps suggests waiting for a better entry point.

OpScore is DiamondOps' composite rating of a card's in-game performance value. Ray Kerr earns an OpScore of 52.1 on Legend difficulty, ranking #2772 among all cards and #522 among Relief Pitchers.

Live Series cards like Ray Kerr's are the ones Diamond Radar scores: it reads a player's real MLB production and predicts what the next roster update will do to the card — the predicted rating, the tier jump, and how likely the upgrade is. Ratings only move at a roster update, and not every Live Series card is scored in a given window. Model v11: of the 162 cards it scored 70 or above in its 1 graded update, 72% were upgraded, against 21% by chance: 3.5× better.
