Liam Doyle is a Red Diamond 99 OVR Starting Pitcher card for the Cardinals, part of the Pipeline set in MLB The Show's Diamond Dynasty. He throws left-handed. The card was added to Diamond Dynasty in August 2026.

On the mound, Liam Doyle works with a 5-pitch arsenal led by a 99 mph 4-Seam Fastball and a 95 mph Sinker. His pitching ratings include 99 Velocity, 82 Control, and 99 Break. The profile favors a movement-heavy arsenal built to miss bats.

DiamondOps grades each pitch in Liam Doyle's arsenal: 4-Seam Fastball (S), Cutter (S), Sinker (S), Splitter (A), and Slurve (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. Its 99 mph 4-Seam Fastball 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.

Liam Doyle is not currently traded on the open Diamond Dynasty market — cards like this are typically earned through programs or collections rather than bought with stubs.

OpScore is DiamondOps' composite rating of a card's in-game performance value. Liam Doyle earns an OpScore of 93.3 on Legend difficulty, ranking #385 among all cards and #58 among Starting Pitchers.
