Basic description of 2018 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, generates more whiffs/swing compared to other pitchers' fourseamers, has some natural sinking action and has well above average velo. His slider is much harder than usual and results in somewhat more flyballs compared to other pitchers' sliders. His change has slight armside fade. His sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers and is blazing fast. His curve (take this with a grain of salt because he's only thrown 14 of them in 2018) generates an extremely high number of swings & misses compared to other pitchers' curves, has very little depth, has primarily 12-6 movement, results in more flyballs compared to other pitchers' curves and is slightly harder than usual.
