Tyler Alexander has thrown 2,801 pitches that have been tracked by the PITCHf/x system between 2019 and 2021, all of them occuring in the MLB Regular Season. In 2021, he has relied primarily on his Cutter (87mph), also mixing in a Change (84mph), Sinker (91mph), Fourseam Fastball (91mph) and Slider (83mph). He also rarely throws a Curve (82mph).
In 2021, compared to other LHP:
His cutter has sweeping cut action, results in more flyballs compared to other pitchers' cutters and has some natural sink. His change is slightly firmer than usual, results in somewhat more groundballs compared to other pitchers' changeups and has some natural sink to it. His sinker has less armside run than typical and results in somewhat more flyballs compared to other pitchers' sinkers. His fourseam fastball has less armside movement than typical, has some natural sinking action and has essentially average velo. His slider generates fewer whiffs/swing compared to other pitchers' sliders, has short glove-side cut and has some two-plane movement. His curve (take this with a grain of salt because he's only thrown 6 of them in 2021) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' curves, has little depth and results in somewhat more flyballs compared to other pitchers' curves.
