Welinton Herrera is a Common 61 OVR Relief Pitcher card for the Free Agents, 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, Welinton Herrera works with a 3-pitch arsenal led by a 95 mph 4-Seam Fastball and a 93 mph 2-Seam Fastball. His pitching ratings include 79 Velocity, 47 Control, and 55 Break. The profile favors a balanced mix of command and movement.

DiamondOps grades each pitch in Welinton Herrera's arsenal: Slider (S), 4-Seam Fastball (S), and 2-Seam Fastball (S). 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 2-Seam Fastball, so the two share a release look. Velocity works against the card here — its 79 mph 4-Seam Fastball 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, Welinton Herrera currently buys for about 7 stubs, with sell orders near 0 stubs. Over the past 7 days the buy price has climbed roughly 17%. 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. Welinton Herrera earns an OpScore of 47.9 on Legend difficulty, ranking #2877 among all cards and #610 among Relief Pitchers.
