Their change using a circle change grip generates an extremely high number of swings & misses compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups and has some natural sink to it. Their curve has little depth. Their fourseam fastball (take this with a grain of salt because they've only thrown 17 of them in 2025) is basically never swung at and missed compared to other pitchers' fourseamers, has some natural sinking action, has essentially average velo and results in somewhat more flyballs compared to other pitchers' fourseamers.
