In 2025, they have relied primarily on their Sinker (96mph), Curve (84mph) and Fourseam Fastball (96mph), also mixing in a Slow Curve (78mph) and Change (89mph). He also rarely throws a Cutter (90mph).
In 2025, compared to other RHP:
Their sinker is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers, is basically never swung at and missed compared to other pitchers' sinkers, is blazing fast, has slight armside run and has some natural sinking action. Their curve is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' curves, has primarily 12-6 movement, has little depth and results in somewhat more flyballs compared to other pitchers' curves. Their fourseam fastball has heavy sinking action, results in many more groundballs compared to other pitchers' fourseamers, has well above average velo and has slight armside run. Their slow curve is a real yakker that's separated from their other curveball due to its big drop and slow speed. Their change is thrown extremely hard, results in somewhat more flyballs compared to other pitchers' changeups, has slight armside fade and has some natural sink to it. Their cutter (take this with a grain of salt because they've only thrown 7 of them in 2025) has heavy sink, is basically never swung at and missed compared to other pitchers' cutters, results in more flyballs compared to other pitchers' cutters and has slightly above average velo.
