In 2022, they relied primarily on their Fourseam Fastball (97mph) and Slider (86mph), also mixing in a Splitter (88mph). He also rarely threw a Sinker (100mph).


In 2022, compared to other LHP:
His fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is thrown at a speed that's borderline unfair and has much less armside movement than typical. His slider sweeps across the zone, is much harder than usual and results in somewhat more flyballs compared to other pitchers' sliders. His splitter is thrown extremely hard, has dives down out of the zone, has surprising cut action, generates more whiffs/swing compared to other pitchers' splitters and results in somewhat more groundballs compared to other pitchers' splitters. 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 surprisingly little armside run, results in more flyballs compared to other pitchers' sinkers and has little sinking action compared to a true sinker.
