Andrew Chafin has thrown 9,211 pitches that have been tracked by the PITCHf/x system between 2014 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Sinker (90mph) and Slider (81mph), also mixing in a Fourseam Fastball (90mph). He also rarely throws a Change (84mph).
In 2025, compared to other LHP:
Their sinker results in more flyballs compared to other pitchers' sinkers and has less armside run than typical. Their 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 and has exceptional depth. Their fourseam fastball generates more whiffs/swing compared to other pitchers' fourseamers, results in somewhat more groundballs compared to other pitchers' fourseamers, has slightly below average velo and has slightly less natural movement than typical. Their change (take this with a grain of salt because they've only thrown 8 of them in 2025) has surprising cut action, generates a high number of swings & misses compared to other pitchers' changeups, is an extreme flyball pitch compared to other pitchers' changeups and is slightly firmer than usual.
