Jack Flaherty is a Silver 75 OVR Starting Pitcher card for the Tigers, 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, Jack Flaherty works with a 5-pitch arsenal led by a 93 mph 4-Seam Fastball and a 91 mph Sinker. His pitching ratings include 71 Velocity, 69 Control, and 71 Break. The profile favors a balanced mix of command and movement.

DiamondOps grades each pitch in Jack Flaherty's arsenal: Slider (S), 4-Seam Fastball (S), Sinker (S), Circle Change (A), and Knuckle-curve (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 71 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.
