Non-MLB
Shohei Ohtani has thrown 4,201 pitches that have been tracked by the PITCHf/x system between 2018 and 2022, including pitches thrown in the MLB Regular Season and Spring Training. In 2022, they have relied primarily on their Fourseam Fastball (97mph) and Slider (85mph), also mixing in a Splitter (89mph) and Curve (78mph). He also rarely throws a Cutter (90mph) and Change (92mph).
In 2022, compared to other RHP:
His fourseam fastball is blazing fast, has much less armside movement than typical, has some natural sinking action and results in somewhat more groundballs compared to other pitchers' fourseamers. His slider sweeps across the zone, is an extreme flyball pitch compared to other pitchers' sliders, generates more whiffs/swing compared to other pitchers' sliders and has less than expected depth. His splitter is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' splitters, has slight cut action and has some natural sink to it. His curve generates a high number of swings & misses compared to other pitchers' curves and has a sharp downward bite. His cutter has heavy sink, is an extreme flyball pitch compared to other pitchers' cutters, generates more whiffs/swing compared to other pitchers' cutters, has slightly above average velo and has strong cutting action. His change (take this with a grain of salt because he's only thrown 3 of them in 2022) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups, has slight armside fade and has some natural sink to it.
