On the mound, Jim Kaat works with a 5-pitch arsenal led by a 94 mph Sinker and a 88 mph Slider. His pitching ratings include 95 Velocity, 0 Control, and 96 Break. The profile favors a movement-heavy arsenal built to miss bats. Notable quirks include Stopper from a total of 4 quirks.

DiamondOps grades each pitch in Jim Kaat's arsenal: Slider (S), Sinker (S), Curveball (B), Slurve (B), and Screwball (C). 2 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 Slider off the Sinker, so the two share a release look. Arsenal grades are the same at every difficulty — unlike a hitter's OpScore, a pitch mix does not re-weight as you climb.
