Ryan Zeferjahn is a Silver 77 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 121 stubs, with sell orders near 0 stubs. Over the past 7 days the buy price has climbed roughly 36%. Its quick-sell value of 100 stubs sits at or above the sell price, making it quick-sell viable. 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 70.6 on Legend difficulty, ranking #1276 among all cards and #95 among Relief Pitchers.
