Basic description of 2020 pitches compared to other RHP:
His fourseam fastball is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, has some natural sinking action and has slightly above average velo. His slider is an extreme flyball pitch compared to other pitchers' sliders and generates more whiffs/swing compared to other pitchers' sliders. His curve (take this with a grain of salt because he's only thrown 9 of them in 2020) has very little depth, generates more whiffs/swing compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves and has slight glove-side movement. His slow curve (take this with a grain of salt because he's only thrown 4 of them in 2020) is a real yakker that's separated from his other curveball due to its big drop and slow speed. His change (take this with a grain of salt because he's only thrown 2 of them in 2020) is basically never swung at and missed compared to other pitchers' changeups, has surprising cut action, is much firmer than usual, results in more flyballs compared to other pitchers' changeups and has some natural sink to it.
