Basic description of 2019 pitches compared to other RHP:
His fourseam fastball has heavy sinking action, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, has an obvious tail and is blazing fast. His slider has short glove-side cut and has some two-plane movement. His change is thrown extremely hard, has an obvious armside fade, generates more whiffs/swing compared to other pitchers' changeups, results in somewhat more flyballs compared to other pitchers' changeups and has some natural sink to it.
