Although they have not thrown an MLB pitch in 2023, Jack Flaherty threw 9,446 pitches that were tracked by the PITCHf/x system between 2017 and 2022, including pitches thrown in the MLB Regular Season and Spring Training. In 2022, they relied primarily on their Fourseam Fastball (93mph) and Slider (84mph), also mixing in a Curve (77mph) and Sinker (91mph). He also rarely threw a Cutter (88mph) and Change (87mph).


In 2022, compared to other RHP:
His fourseam fastball has less armside movement than typical, has some natural sinking action, has essentially average velo and results in somewhat more groundballs compared to other pitchers' fourseamers. His slider has short glove-side cut, results in somewhat more flyballs compared to other pitchers' sliders and has some two-plane movement. His curve has a sharp downward bite, results in somewhat more groundballs compared to other pitchers' curves and has slight glove-side movement. His sinker is basically never swung at and missed compared to other pitchers' sinkers, has surprisingly little armside run, results in somewhat more flyballs compared to other pitchers' sinkers and has some natural sinking action. His cutter (take this with a grain of salt because he's only thrown 13 of them in 2022) is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters, has some natural sink and has strong cutting action. His change (take this with a grain of salt because he's only thrown 6 of them in 2022) is basically never swung at and missed compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups and is slightly firmer than usual.
