Jefry Yan

Jefry Yan is a Common 58 OVR Relief Pitcher card for the Mets, part of the Live 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, Jefry Yan 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 81 Velocity, 54 Control, and 56 Break. The profile favors a balanced mix of command and movement.

DiamondOps grades each pitch in Jefry Yan'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 81 mph 2-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, Jefry Yan currently buys for about 110 stubs, with sell orders near 5 stubs. Over the past 7 days the buy price has climbed roughly 72%. Flipping at current buy and sell prices nets roughly 92 stubs, about a 1533% return. DiamondOps flags the card as currently overpriced.

OpScore is DiamondOps' composite rating of a card's in-game performance value. Jefry Yan earns an OpScore of 47.9 on Legend difficulty, ranking #3366 among all cards and #671 among Relief Pitchers.

Live Series cards like Jefry Yan'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.
