Luis Gastelum is a Common 48 OVR Relief Pitcher card for the Cardinals, part of the Live set in MLB The Show's Diamond Dynasty. He throws right-handed. The card was added to Diamond Dynasty in July 2026.

On the mound, Luis Gastelum works with a 5-pitch arsenal led by a 92 mph 4-Seam Fastball and a 92 mph Sinker. His pitching ratings include 77 Velocity, 49 Control, and 54 Break. The profile favors a balanced mix of command and movement.

DiamondOps grades each pitch in Luis Gastelum'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 77 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, Luis Gastelum currently buys for about 90 stubs, with sell orders near 0 stubs. Over the past 7 days the price has held roughly steady. Its quick-sell value of 5 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. Luis Gastelum earns an OpScore of 49.9 on Legend difficulty, ranking #2804 among all cards and #556 among Relief Pitchers.

Live Series cards like Luis Gastelum'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. Across the season so far, 55% of the cards Radar flags go on to be upgraded, against a 26% background rate across all scored cards — 2.1× better than chance (n=1,061).
