In 2022, they relied primarily on their Fourseam Fastball (96mph) and Curve (82mph), also mixing in a Sinker (96mph) and Slider (83mph). He also rarely threw a Change (89mph).
In 2022, compared to other RHP:
His fourseam fastball generates a very high amount of groundballs compared to other pitchers' fourseamers, has much less armside movement than typical, has some natural sinking action and has well above average velo. His curve generates a high number of swings & misses compared to other pitchers' curves, is much harder than usual, has primarily 12-6 movement and results in somewhat more flyballs compared to other pitchers' curves. His sinker is blazing fast and has less armside run than typical. His slider sweeps across the zone, has exceptional depth, generates more whiffs/swing compared to other pitchers' sliders and results in more flyballs compared to other pitchers' sliders. His change (take this with a grain of salt because he's only thrown 6 of them in 2022) is thrown extremely hard, results in more flyballs compared to other pitchers' changeups and has some natural sink to it.
