Basic description of 2019 pitches compared to other RHP:
His curve generates more whiffs/swing compared to other pitchers' curves, is slightly harder than usual, results in somewhat more groundballs compared to other pitchers' curves and has slight glove-side movement. His fourseam fastball generates more whiffs/swing compared to other pitchers' fourseamers, has some natural sinking action and has slightly above average velo. His change dives down out of the zone, generates a high number of swings & misses compared to other pitchers' changeups, is much firmer than usual, results in many more groundballs compared to other pitchers' changeups and has slight armside fade. His sinker has slight armside run and has slightly above average velo. His slider (take this with a grain of salt because he's only thrown 12 of them in 2019) is thrown extremely hard and has less than expected depth.
