Their fourseam fastball is an extreme flyball pitch compared to other pitchers' fourseamers, has much less armside movement than typical and has slightly above average velo. Their slider is thrown extremely hard and has short glove-side cut. Their curve is basically never swung at and missed compared to other pitchers' curves, is an extreme flyball pitch compared to other pitchers' curves and has a sharp downward bite. Their splitter (take this with a grain of salt because they've only thrown 4 of them in 2026) is basically never swung at and missed compared to other pitchers' splitters, has surprising cut action, is an extreme flyball pitch compared to other pitchers' splitters and has below average velo.
