Jack O'Loughlin has thrown 3,624 pitches that have been tracked by the PITCHf/x system between 2021 and 2024, including pitches thrown in the MLB Regular Season, The World Baseball Classic and Spring Training. In 2024, they have relied primarily on their Fourseam Fastball (92mph) and Slider (83mph), also mixing in a Change (85mph) and Curve (76mph). He also rarely throws a Sinker (89mph).
In 2024, compared to other LHP:
Their fourseam fastball has some natural sinking action and has essentially average velo. Their slider results in somewhat more flyballs compared to other pitchers' sliders and has some two-plane movement. Their change generates a high number of swings & misses compared to other pitchers' changeups, has slight cut action, is slightly firmer than usual, results in somewhat more groundballs compared to other pitchers' changeups and has some natural sink to it. Their curve has a sharp downward bite, results in somewhat more flyballs compared to other pitchers' curves and has slight glove-side movement. Their sinker (take this with a grain of salt because they've only thrown 1 of them in 2024) has heavy sinking action, is basically never swung at and missed compared to other pitchers' sinkers, has an obvious tail and is an extreme flyball pitch compared to other pitchers' sinkers.
