Their cutter is thrown at a speed that's borderline unfair, explodes on the hitter, has little cutting action and results in somewhat more flyballs compared to other pitchers' cutters. Their slider is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sliders, has exceptional depth, has short glove-side cut and is much harder than usual. Their sinker is an extreme flyball pitch compared to other pitchers' sinkers and is blazing fast. Their splitter is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' splitters and is an extreme flyball pitch compared to other pitchers' splitters.
