Their fourseam fastball (take this with a grain of salt because they've only thrown 2 of them in 2025) is basically never swung at and missed 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.
