Basic description of 2017 pitches compared to other RHP:
His fourseam fastball has slight armside run and has slightly above average velo. His slider is thrown extremely hard, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sliders, is basically never swung at and missed compared to other pitchers' sliders, has much less depth than expected and has primarily 12-6 movement. His change has an obvious armside fade, generates fewer whiffs/swing compared to other pitchers' changeups and is slightly firmer than usual. His curve generates an extremely high number of swings & misses compared to other pitchers' curves, has very little depth, has primarily 12-6 movement, is much harder than usual and results in more flyballs compared to other pitchers' curves. His sinker (take this with a grain of salt because he's only thrown 1 of them in 2017) is basically never swung at and missed compared to other pitchers' sinkers, has an obvious tail and is an extreme flyball pitch compared to other pitchers' sinkers.
