In 2022, they relied primarily on their Slider (82mph) and Fourseam Fastball (92mph), also mixing in a Curve (77mph). He also rarely threw a Change (87mph).
In 2022, compared to other LHP:
His slider generates a high number of swings & misses compared to other pitchers' sliders. His fourseam fastball has essentially average velo, results in somewhat more flyballs compared to other pitchers' fourseamers and has slightly less natural movement than typical. His curve results in more flyballs compared to other pitchers' curves and has slight glove-side movement. His change (take this with a grain of salt because he's only thrown 9 of them in 2022) is thrown extremely hard and is basically never swung at and missed compared to other pitchers' changeups.
