In 2023, compared to other LHP:
Their slider has short glove-side cut. Their fourseam fastball (take this with a grain of salt because they've only thrown 17 of them in 2023) generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is straight as an arrow, is an extreme flyball pitch compared to other pitchers' fourseamers, has some natural sinking action and has essentially average velo. Their curve (take this with a grain of salt because they've only thrown 5 of them in 2023) is basically never swung at and missed compared to other pitchers' curves, is an extreme flyball pitch compared to other pitchers' curves, has below average velo and has a sharp downward bite. Their change (take this with a grain of salt because they've only thrown 4 of them in 2023) generates an extremely high number of swings & misses compared to other pitchers' changeups, has surprising cut action, is an extreme flyball pitch compared to other pitchers' changeups and has below average velo.
