Gavin Collyer is a Common 61 OVR Relief Pitcher card for the Rangers, 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, Gavin Collyer works with a 4-pitch arsenal led by a 92 mph 4-Seam Fastball and a 90 mph Sinker. His pitching ratings include 68 Velocity, 50 Control, and 54 Break. The profile favors a balanced mix of command and movement.

DiamondOps grades each pitch in Gavin Collyer's arsenal: Slider (S), 4-Seam Fastball (S), Sinker (S), and Changeup (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 68 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, Gavin Collyer currently buys for about 80 stubs, with sell orders near 0 stubs. Over the past 7 days the buy price has climbed roughly 471%. Its quick-sell value of 5 stubs sits at or above the sell price, making it quick-sell viable. DiamondOps flags the card as currently overpriced.
