Ryan Zeferjahn

Ryan Zeferjahn is a Silver 76 OVR Relief Pitcher card for the Cubs, part of the Live set in MLB The Show's Diamond Dynasty. He throws right-handed. The card was added to Diamond Dynasty in April 2026.

On the mound, Ryan Zeferjahn works with a 5-pitch arsenal led by a 97 mph 4-Seam Fastball and a 91 mph Cutter. His pitching ratings include 91 Velocity, 49 Control, and 88 Break. The profile favors a movement-heavy arsenal built to miss bats.

DiamondOps grades each pitch in Ryan Zeferjahn's arsenal: Slider (S), 4-Seam Fastball (S), Sweeper (S), Cutter (S), and Slurve (B). 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 Cutter off the Slider, so the two share a release look. Velocity works against the card here — its 91 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, Ryan Zeferjahn currently buys for about 133 stubs, with sell orders near 75 stubs. Over the past 7 days the buy price has fallen roughly 10%. Flipping at current buy and sell prices nets roughly 42 stubs, about a 55% return. DiamondOps flags the card as currently overpriced.

OpScore is DiamondOps' composite rating of a card's in-game performance value. Ryan Zeferjahn earns an OpScore of 69 on Legend difficulty, ranking #1532 among all cards and #128 among Relief Pitchers.

Live Series cards like Ryan Zeferjahn'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.
