Their fourseam fastball (take this with a grain of salt because they've only thrown 7 of them in 2025) has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has essentially average velo and has slight armside run.
