Sean Newcomb is a Bronze 73 OVR Relief Pitcher card for the White Sox, part of the Live set in MLB The Show's Diamond Dynasty. He throws left-handed. The card was added to Diamond Dynasty in April 2026.

On the mound, Sean Newcomb works with a 5-pitch arsenal led by a 93 mph 4-Seam Fastball and a 93 mph Sinker. His pitching ratings include 83 Velocity, 58 Control, and 88 Break. The profile favors a movement-heavy arsenal built to miss bats.

DiamondOps grades each pitch in Sean Newcomb's arsenal: 4-Seam Fastball (S), Sinker (S), Cutter (S), Circle Change (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. Velocity works against the card here — its 83 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.
