Non-MLB
Although they have not thrown an MLB pitch in 2023, Tucker Davidson threw 1,336 pitches that were tracked by the PITCHf/x system between 2018 and 2022, including pitches thrown in the MLB Regular Season and the MLB Postseason. In 2022, they relied primarily on their Slider (87mph) and Fourseam Fastball (93mph), also mixing in a Curve (78mph). He also rarely threw a Change (85mph) and Sinker (93mph).
In 2022, compared to other LHP:
His slider is thrown extremely hard, has short glove-side cut, results in somewhat more groundballs compared to other pitchers' sliders and has some two-plane movement. His fourseam fastball is straight as an arrow and has slightly above average velo. His curve is slightly harder than usual. His change is basically never swung at and missed compared to other pitchers' changeups and is much firmer than usual. His sinker (take this with a grain of salt because he's only thrown 8 of them in 2022) is basically never swung at and missed compared to other pitchers' sinkers, has surprisingly little armside run, results in more flyballs compared to other pitchers' sinkers, has little sinking action compared to a true sinker and has slightly above average velo.
