BETA Feature:
Basic description of 2019 pitches compared to other RHP:
His fourseam fastball generates more whiffs/swing compared to other pitchers' fourseamers, has less armside movement than typical, has some natural sinking action and has slightly above average velo. His slider generates a high number of swings & misses compared to other pitchers' sliders and has short glove-side cut. His sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, has surprisingly little armside run and has some natural sinking action. His curve is a real worm killer that generates an extreme number of groundballs compared to other pitchers' curves, generates more whiffs/swing compared to other pitchers' curves, has a sharp downward bite and has slight glove-side movement. His change is much firmer than usual.
