Jack O'Loughlin has thrown 3,918 pitches that have been tracked by the PITCHf/x system between 2021 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 Fourseam Fastball (90mph) and Slider (83mph), also mixing in a Curve (74mph). He also rarely throws a Splitter (85mph) and Change (84mph).
In 2025, compared to other LHP:
Their fourseam fastball generates fewer whiffs/swing compared to other pitchers' fourseamers, has some natural sinking action, has essentially average velo and has slightly less natural movement than typical. Their slider has some two-plane movement. Their curve has an exceptional bite, generates a high number of swings & misses compared to other pitchers' curves, results in somewhat more flyballs compared to other pitchers' curves, has slight glove-side movement and has slightly below average velo. Their splitter (take this with a grain of salt because they've only thrown 4 of them in 2025) is basically never swung at and missed compared to other pitchers' splitters, has surprising cut action, is an extreme flyball pitch compared to other pitchers' splitters, has some natural sink to it and is slightly firmer than usual. Their change (take this with a grain of salt because they've only thrown 2 of them in 2025) is basically never swung at and missed compared to other pitchers' changeups, has surprising cut action, dives down out of the zone, is an extreme flyball pitch compared to other pitchers' changeups and is slightly firmer than usual.
