DiamondOps grades each pitch in Steven Matz's arsenal: Slider (S), Sinker (S), Circle Change (A), and Curveball (B). 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 Sinker off the Circle Change, 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.
