Basic description of 2019 pitches compared to other RHP:
His fourseam fastball has slightly above average velo. His slider is basically never swung at and missed compared to other pitchers' sliders, results in more flyballs compared to other pitchers' sliders, has short glove-side cut and has some two-plane movement. His sinker generates fewer whiffs/swing compared to other pitchers' sinkers, results in somewhat more flyballs compared to other pitchers' sinkers and has slight armside run. His curve is slightly harder than usual. His change (take this with a grain of salt because he's only thrown 1 of them in 2019) is basically never swung at and missed compared to other pitchers' changeups and results in more flyballs compared to other pitchers' changeups.
