Washington Nationals
Andrew Chafin has thrown 9,421 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 has less armside run than typical and results in somewhat more flyballs compared to other pitchers' sinkers. 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, has exceptional depth and has primarily 12-6 movement. Their fourseam fastball generates a very high amount of groundballs compared to other pitchers' fourseamers, has essentially average velo and has slightly less natural movement than typical. Their change (take this with a grain of salt because they've only thrown 10 of them in 2025) has surprising cut action, is an extreme flyball pitch compared to other pitchers' changeups and is slightly firmer than usual.
