In 2022, compared to other RHP:
His fourseam fastball comes in below hitting speed, generates fewer whiffs/swing compared to other pitchers' fourseamers, results in more flyballs compared to other pitchers' fourseamers and has some natural sinking action. His change (take this with a grain of salt because he's only thrown 11 of them in 2022) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' changeups, has surprising cut action, has an extreme amount of backspin and results in somewhat more flyballs compared to other pitchers' changeups.
