Although they have not thrown an MLB pitch in 2023, Daniel Norris threw 10,028 pitches that were tracked by the PITCHf/x system between 2014 and 2022, including pitches thrown in the MLB Regular Season and Spring Training. In 2022, they relied primarily on their Fourseam Fastball (91mph), Slider (80mph) and Change (87mph), also mixing in a Sinker (91mph). He also rarely threw a Curve (76mph).
In 2022, compared to other LHP:
His fourseam fastball generates more whiffs/swing compared to other pitchers' fourseamers, has essentially average velo and has slightly less natural movement than typical. His slider sweeps across the zone and has some two-plane movement. His change is thrown extremely hard, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' changeups, dives down out of the zone and generates a high number of swings & misses compared to other pitchers' changeups. His sinker has less armside run than typical and results in somewhat more flyballs compared to other pitchers' sinkers. His curve (take this with a grain of salt because he's only thrown 16 of them in 2022) has an exceptional bite and is an extreme flyball pitch compared to other pitchers' curves.
