In 2022, they relied primarily on their Fourseam Fastball (94mph) and Slider (84mph), also mixing in a Change (87mph) and Sinker (94mph).
In 2022, compared to other LHP:
His fourseam fastball is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, is basically never swung at and missed compared to other pitchers' fourseamers, has some natural sinking action, has well above average velo and has slightly less natural movement than typical. His slider has exceptional depth, generates fewer whiffs/swing compared to other pitchers' sliders, has short glove-side cut and results in somewhat more flyballs compared to other pitchers' sliders. His change is thrown extremely hard, has surprising cut action, is an extreme flyball pitch compared to other pitchers' changeups and generates fewer whiffs/swing compared to other pitchers' changeups. His sinker (take this with a grain of salt because he's only thrown 15 of them in 2022) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has well above average velo, has less armside run than typical and has some natural sinking action.
