Michael Petersen is a Silver 76 OVR Relief Pitcher card for the Marlins, 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, Michael Petersen works with a 3-pitch arsenal led by a 97 mph 4-Seam Fastball and a 95 mph Sinker. His pitching ratings include 99 Velocity, 50 Control, and 79 Break. The profile favors a movement-heavy arsenal built to miss bats.

DiamondOps grades each pitch in Michael Petersen's arsenal: 4-Seam Fastball (S), Cutter (S), and Sinker (S). 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, Michael Petersen currently buys for about 89 stubs, with sell orders near 75 stubs. Over the past 7 days the price has held roughly steady. Flipping at current buy and sell prices nets roughly 3 stubs, about a 4% return. DiamondOps suggests waiting for a better entry point.

OpScore is DiamondOps' composite rating of a card's in-game performance value. Michael Petersen earns an OpScore of 63.1 on Legend difficulty, ranking #1634 among all cards and #214 among Relief Pitchers.
