Roy Halladay is a Diamond 87 OVR Starting Pitcher card for the Blue Jays, 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, Roy Halladay works with a 5-pitch arsenal led by a 95 mph 4-Seam Fastball and a 94 mph Sinker. His pitching ratings include 90 Velocity, 90 Control, and 92 Break. The profile favors a balanced mix of command and movement. Notable quirks include Break Outlier from a total of 3 quirks.

DiamondOps grades each pitch in Roy Halladay's arsenal: Sinker (S), Cutter (S), 4-Seam Fastball (S), Splitter (A), and Curveball (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 90 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.

On the Diamond Dynasty market, Roy Halladay currently buys for about 3,879 stubs, with sell orders near 2,334 stubs. Over the past 7 days the price has held roughly steady. Flipping at current buy and sell prices nets roughly 1,155 stubs, about a 49% return. DiamondOps suggests waiting for a better entry point.
