Colin Holderman

Colin Holderman is a Silver 76 OVR Relief Pitcher card for the Guardians, 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, Colin Holderman 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, 61 Control, and 79 Break. The profile favors a movement-heavy arsenal built to miss bats. Notable quirks include Outlier I.

DiamondOps grades each pitch in Colin Holderman's arsenal: Sinker (S), Sweeper (S), Cutter (S), 4-Seam Fastball (S), and Splitter (A). 4 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. 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, Colin Holderman currently buys for about 195 stubs, with sell orders near 75 stubs. Over the past 7 days the buy price has fallen roughly 12%. Flipping at current buy and sell prices nets roughly 98 stubs, about a 129% return. DiamondOps suggests waiting for a better entry point.

OpScore is DiamondOps' composite rating of a card's in-game performance value. Colin Holderman earns an OpScore of 78.8 on Legend difficulty, ranking #1184 among all cards and #48 among Relief Pitchers.
