Pitch Repertoire At-A-Glance

Although they have not thrown an MLB pitch in 2023, Sean Doolittle threw 7,469 pitches that were tracked by the PITCHf/x system between 2012 and 2022, including pitches thrown in the MLB Regular Season, the MLB Postseason and Spring Training. In 2022, they relied primarily on their Fourseam Fastball (94mph) and Slider (78mph). He also rarely threw a Splitter (81mph).


In 2022, compared to other LHP:
His fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has much less armside movement than typical, results in somewhat more flyballs compared to other pitchers' fourseamers, has slightly above average velo and has some added backspin. His slider (take this with a grain of salt because he's only thrown 12 of them in 2022) generates an extremely high number of swings & misses compared to other pitchers' sliders, sweeps across the zone, results in more flyballs compared to other pitchers' sliders, has below average velo and has some two-plane movement. His splitter (take this with a grain of salt because he's only thrown 2 of them in 2022) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' splitters, is an extreme flyball pitch compared to other pitchers' splitters, has movement that suggests an extreme amount of backspin and has slight cut action.
