Ethan Pecko is a Common 61 OVR Starting Pitcher card for the Astros, part of the Live set in MLB The Show's Diamond Dynasty. He throws right-handed. The card was added to Diamond Dynasty in August 2026.

On the mound, Ethan Pecko works with a 5-pitch arsenal led by a 94 mph 4-Seam Fastball and a 84 mph Slider. His pitching ratings include 72 Velocity, 51 Control, and 56 Break. The profile favors a balanced mix of command and movement.

DiamondOps grades each pitch in Ethan Pecko's arsenal: Slider (S), 4-Seam Fastball (S), Circle Change (A), Curveball (B), and Slurve (B). 2 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 Slider, so the two share a release look. Velocity works against the card here — its 72 mph 4-Seam Fastball 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.
