Chicago Cubs
Tom Cosgrove has thrown 2,544 pitches that have been tracked by the PITCHf/x system between 2022 and 2025, including pitches thrown in the MLB Regular Season, The World Baseball Classic and Spring Training. In 2025, they have relied primarily on their Slider (76mph) and Sinker (89mph), also mixing in a Fourseam Fastball (90mph). He also rarely throws a Cutter (89mph).
In 2025, compared to other LHP:
Their slider comes in below hitting speed, sweeps across the zone, results in somewhat more flyballs compared to other pitchers' sliders and has some two-plane movement. Their sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, has heavy sinking action, has less armside run than typical and results in somewhat more flyballs compared to other pitchers' sinkers. Their fourseam fastball has heavy sinking action, has essentially average velo, results in somewhat more groundballs compared to other pitchers' fourseamers and has slightly less natural movement than typical. Their cutter (take this with a grain of salt because they've only thrown 6 of them in 2025) generates an extremely high number of swings & misses compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters, has well above average velo and has little cutting action.
