Basic description of 2018 pitches compared to other RHP:
His sinker has slightly above average velo. His cutter has well above average velo, has good "rise" and has little cutting action. His curve generates fewer whiffs/swing compared to other pitchers' curves, is slightly harder than usual and has slight glove-side movement. His slider results in more flyballs compared to other pitchers' sliders and has some two-plane movement. His fourseam fastball (take this with a grain of salt because he's only thrown 18 of them in 2018) is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has some natural sinking action and has essentially average velo.
