His fourseam fastball (take this with a grain of salt because he's only thrown 1 of them in 2022) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers and has some natural sinking action.
