Pittsburgh Pirates
Bailey Falter has thrown 6,967 pitches that have been tracked by the PITCHf/x system between 2021 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Fourseam Fastball (92mph), also mixing in a Slider (85mph), Sinker (91mph) and Curve (77mph). He also rarely throws a Change (85mph).
In 2025, compared to other LHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has much less armside movement than typical, has essentially average velo and results in somewhat more groundballs compared to other pitchers' fourseamers. Their slider is basically never swung at and missed compared to other pitchers' sliders, is much harder than usual, has less than expected depth and results in somewhat more flyballs compared to other pitchers' sliders. Their sinker (take this with a grain of salt because they've only thrown 18 of them in 2025) has surprisingly little armside run and has little sinking action compared to a true sinker. Their curve (take this with a grain of salt because they've only thrown 18 of them in 2025) is basically never swung at and missed compared to other pitchers' curves, is an extreme flyball pitch compared to other pitchers' curves, has little depth and has primarily 12-6 movement. Their change (take this with a grain of salt because they've only thrown 6 of them in 2025) has surprising cut action, is an extreme flyball pitch compared to other pitchers' changeups and is slightly firmer than usual.
