Basic description of 2019 pitches compared to other RHP:
His fourseam fastball has heavy sinking action, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, has well above average velo and has slight armside run. His slider is thrown extremely hard, generates more whiffs/swing compared to other pitchers' sliders, has less than expected depth and has primarily 12-6 movement. His curve results in somewhat more flyballs compared to other pitchers' curves. His change is basically never swung at and missed compared to other pitchers' changeups, is much firmer than usual and results in many more groundballs compared to other pitchers' changeups. His sinker (take this with a grain of salt because he's only thrown 9 of them in 2019) generates an extremely high number of swings & misses compared to other pitchers' sinkers, is blazing fast, results in somewhat more flyballs compared to other pitchers' sinkers and has some natural sinking action.
