In 2022, they relied primarily on their Fourseam Fastball (95mph) and Slider (87mph), also mixing in a Change (87mph). He also rarely threw a Sinker (94mph).
In 2022, compared to other RHP:
His fourseam fastball has some natural sinking action and has slightly above average velo. His slider has exceptional depth and has short glove-side cut. His change is a real worm killer that generates an extreme number of groundballs compared to other pitchers' changeups, is much firmer than usual, has slight armside fade and has some natural sink to it. His sinker (take this with a grain of salt because he's only thrown 2 of them in 2022) generates an extremely high number of swings & misses compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has slightly above average velo and has some natural sinking action.
