Basic description of 2019 pitches compared to other RHP:
His fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is blazing fast, has slight armside run and has some added backspin. His slider is thrown extremely hard. His curve has an exceptional bite, generates a very high amount of groundballs compared to other pitchers' curves, is much harder than usual and has slight glove-side movement. His change is thrown extremely hard, generates a high number of swings & misses compared to other pitchers' changeups, has a lot of backspin and has slight armside fade. His sinker (take this with a grain of salt because he's only thrown 13 of them in 2019) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, is blazing fast, has little sinking action compared to a true sinker and has slight armside run.
