Their fourseam fastball (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' fourseamers, is straight as an arrow and has slightly below average velo. Their change (take this with a grain of salt because they've only thrown 1 of them in 2023) is basically never swung at and missed compared to other pitchers' changeups, has surprising cut action, is an extreme flyball pitch compared to other pitchers' changeups and has an extreme amount of backspin. Their slider (take this with a grain of salt because they've only thrown 1 of them in 2023) is basically never swung at and missed compared to other pitchers' sliders, has exceptional depth and results in more flyballs compared to other pitchers' sliders.
