Their fourseam fastball generates a high number of swings & misses compared to other pitchers' fourseamers, has less armside movement than typical and has essentially average velo. Their curve generates an extremely high number of swings & misses compared to other pitchers' curves, has primarily 12-6 movement, is much harder than usual, has little depth and results in somewhat more flyballs compared to other pitchers' curves. Their change generates an extremely high number of swings & misses compared to other pitchers' changeups and has some natural sink to it.
