Detroit Tigers
Although they have not thrown an MLB pitch in 2023, Andrew Chafin threw 6,784 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 Sinker (92mph), Slider (83mph) and Fourseam Fastball (92mph). He also rarely threw a Change (84mph).
In 2022, compared to other LHP:
His sinker has less armside run than typical. His slider generates an extremely high number of swings & misses compared to other pitchers' sliders, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sliders, has primarily 12-6 movement and has some two-plane movement. His fourseam fastball has some natural sinking action, has essentially average velo and results in somewhat more groundballs compared to other pitchers' fourseamers. His change (take this with a grain of salt because he's only thrown 7 of them in 2022) is basically never swung at and missed compared to other pitchers' changeups, is an extreme flyball pitch compared to other pitchers' changeups, has slight cut action and is slightly firmer than usual.
