Ian Seymour

Ian Seymour is a Silver 79 OVR Starting Pitcher card for the Rays, part of the Live set in MLB The Show's Diamond Dynasty. He throws left-handed. The card was added to Diamond Dynasty in April 2026.

On the mound, Ian Seymour works with a 5-pitch arsenal led by a 92 mph 4-Seam Fastball and a 91 mph Sinker. His pitching ratings include 71 Velocity, 41 Control, and 87 Break. The profile favors a movement-heavy arsenal built to miss bats.

DiamondOps grades each pitch in Ian Seymour's arsenal: 4-Seam Fastball (S), Cutter (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 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.

On the Diamond Dynasty market, Ian Seymour currently buys for about 181 stubs, with sell orders near 0 stubs. Over the past 7 days the buy price has climbed roughly 13%. Its quick-sell value of 150 stubs sits at or above the sell price, making it quick-sell viable. DiamondOps suggests waiting for a better entry point.

OpScore is DiamondOps' composite rating of a card's in-game performance value. Ian Seymour earns an OpScore of 63.3 on Legend difficulty, ranking #1755 among all cards and #375 among Starting Pitchers.

Live Series cards like Ian Seymour's are the ones Diamond Radar scores: it reads a player's real MLB production and predicts what the next roster update will do to the card — the predicted rating, the tier jump, and how likely the upgrade is. Ratings only move at a roster update, and not every Live Series card is scored in a given window. Model v11: of the 162 cards it scored 70 or above in its 1 graded update, 72% were upgraded, against 21% by chance: 3.5× better.
