In 2025, they relied primarily on their Fourseam Fastball (97mph), Splitter (89mph) and Slider (84mph), also mixing in a Sinker (98mph). He also rarely threw a Curve (85mph).
In 2025, compared to other RHP:
Their fourseam fastball has heavy sinking action, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers and is blazing fast. Their splitter is thrown extremely hard, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' splitters and has some natural sink to it. Their slider has some two-plane movement. Their sinker is thrown at a speed that's borderline unfair, results in somewhat more flyballs compared to other pitchers' sinkers, has slight armside run and has some natural sinking action. Their curve (take this with a grain of salt because they've only thrown 2 of them in 2025) is thrown extremely hard, has an exceptional bite, is basically never swung at and missed compared to other pitchers' curves, has primarily 12-6 movement and results in more flyballs compared to other pitchers' curves.
