Ian Seymour

Ian Seymour is a Red Diamond 96 OVR Starting Pitcher card for the Rays, part of the Topps Now set in MLB The Show's Diamond Dynasty. He throws left-handed. The card was added to Diamond Dynasty in July 2026.

On the mound, Ian Seymour works with a 5-pitch arsenal led by a 92 mph 4-Seam Fastball and a 90 mph Sinker. His pitching ratings include 69 Velocity, 88 Control, and 97 Break. The profile favors a balanced mix of command and movement.

DiamondOps grades each pitch in Ian Seymour's arsenal: Slider (S), 4-Seam Fastball (S), Sweeper (S), Sinker (S), and Circle Change (A). 4 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 69 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.

Ian Seymour 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.

OpScore is DiamondOps' composite rating of a card's in-game performance value. Ian Seymour earns an OpScore of 85.6 on Legend difficulty, ranking #1069 among all cards and #199 among Starting Pitchers.
