Basic description of 2018 pitches compared to other RHP:
His curve is thrown extremely hard, generates a high number of swings & misses compared to other pitchers' curves, results in many more groundballs compared to other pitchers' curves and has little depth. His fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is thrown at a speed that's borderline unfair and has slightly less natural movement than typical. His change (take this with a grain of salt because he's only thrown 1 of them in 2018) is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups, has slight cut action and has a lot of backspin.
