Mason Miller

Mason Miller is a Diamond 91 OVR Closer card for the Padres, 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, Mason Miller works with a 3-pitch arsenal led by a 99 mph 4-Seam Fastball and a 88 mph Slider. His pitching ratings include 99 Velocity, 84 Control, and 95 Break. The profile favors a movement-heavy arsenal built to miss bats. Notable quirks include Outlier I from a total of 3 quirks.

DiamondOps grades each pitch in Mason Miller's arsenal: Slider (S), 4-Seam Fastball (S), and Circle Change (A). 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. 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.
