George Kirby — Red Diamond 99 OVR Closer Overview

On the mound, George Kirby works with a 5-pitch arsenal led by a 98 mph 4-Seam Fastball and a 95 mph Sinker. His pitching ratings include 99 Velocity, 99 Control, and 99 Break. The profile favors a balanced mix of command and movement. Notable quirks include Stopper from a total of 3 quirks.
DiamondOps grades each pitch in George Kirby's arsenal: Slider (S), 4-Seam Fastball (S), Sinker (S), Cutter (S), and Curveball (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 4-Seam Fastball off the Sinker, so the two share a release look. Its 99 mph Sinker adds a velocity bonus on top. Arsenal grades are the same at every difficulty — unlike a hitter's OpScore, a pitch mix does not re-weight as you climb.
George Kirby is not currently traded on the open Diamond Dynasty market — cards like this are typically earned through programs or collections rather than bought with stubs.
OpScore is DiamondOps' composite rating of a card's in-game performance value. George Kirby earns an OpScore of 107.2 on Legend difficulty, ranking #63 among all cards and #5 among Closers.
