Basic description of 2020 pitches compared to other RHP:
His slider is thrown extremely hard, has primarily 12-6 movement and results in somewhat more groundballs compared to other pitchers' sliders. His sinker generates a high number of swings & misses compared to other pitchers' sinkers, has well above average velo and has slight armside run. His fourseam fastball has some natural sinking action, has essentially average velo and results in somewhat more flyballs compared to other pitchers' fourseamers. His curve is slightly harder than usual. His change (take this with a grain of salt because he's only thrown 19 of them in 2020) is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups and has some natural sink to it.
