Basic description of 2017 pitches compared to other RHP:
His sinker is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers and has little sinking action compared to a true sinker. His fourseam fastball has essentially average velo and has slightly less natural movement than typical. His slider generates a high number of swings & misses compared to other pitchers' sliders and results in somewhat more groundballs compared to other pitchers' sliders. His change is a prototypical pitch with few remarkable qualities. His curve has little depth, is slightly harder than usual and has primarily 12-6 movement.
