Basic description of 2017 pitches compared to other RHP:
His sinker has slight armside run and has slightly above average velo. His slider generates fewer whiffs/swing 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 fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has slight armside run and has slightly above average velo. His curve has little depth, is slightly harder than usual and results in somewhat more flyballs compared to other pitchers' curves. His change (take this with a grain of salt because he's only thrown 4 of them in 2017) is thrown extremely hard, has an obvious armside fade, results in more flyballs compared to other pitchers' changeups and has some natural sink to it.
