In 2022, they relied primarily on their Slider (86mph), Sinker (97mph) and Fourseam Fastball (98mph). He also rarely threw a Change (91mph).
In 2022, compared to other RHP:
His slider generates more whiffs/swing compared to other pitchers' sliders and has some two-plane movement. His sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, is thrown at a speed that's borderline unfair, has an obvious tail, results in somewhat more groundballs compared to other pitchers' sinkers and has some natural sinking action. His fourseam fastball is blazing fast, has some natural sinking action and has slight armside run. His change (take this with a grain of salt because he's only thrown 1 of them in 2022) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' changeups, has surprising cut action, results in more flyballs compared to other pitchers' changeups and has a lot of backspin.
