Shane Bieber has thrown 5,025 pitches that have been tracked by the PITCHf/x system between 2018 and 2019, all of them occuring in the MLB Regular Season. In 2019, he has relied primarily on his Fourseam Fastball (93mph), Slider (85mph) and Curve (83mph), also mixing in a Change (88mph). He also rarely throws a Sinker (94mph).
Basic description of 2019 pitches compared to other RHP:
His fourseam fastball has essentially average velo. His slider generates more whiffs/swing compared to other pitchers' sliders, has primarily 12-6 movement and results in somewhat more groundballs compared to other pitchers' sliders. His curve generates an extremely high number of swings & misses compared to other pitchers' curves, has primarily 12-6 movement and is much harder than usual. His change is much firmer than usual, results in many more groundballs compared to other pitchers' changeups and has slight armside fade. His sinker (take this with a grain of salt because he's only thrown 1 of them in 2019) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers and has slightly above average velo.
