Clay Buchholz is a Gold 83 OVR Relief Pitcher card for the Red Sox, part of the 2nd Half Heroes 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, Clay Buchholz works with a 5-pitch arsenal led by a 93 mph Sinker and a 93 mph 4-Seam Fastball. His pitching ratings include 89 Velocity, 83 Control, and 99 Break. The profile favors a movement-heavy arsenal built to miss bats. Notable quirks include Break Outlier from a total of 3 quirks.

DiamondOps grades each pitch in Clay Buchholz's arsenal: Sinker (S), Cutter (S), 4-Seam Fastball (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 Sinker off the 4-Seam Fastball, so the two share a release look. Velocity works against the card here — its 89 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.

Clay Buchholz 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.
