Although they have not thrown an MLB pitch in 2023, Steve Cishek threw 12,127 pitches that were tracked by the PITCHf/x system between 2010 and 2022, including pitches thrown in the MLB Regular Season and Spring Training. In 2022, they relied primarily on their Slider (76mph), Sinker (90mph) and Fourseam Fastball (89mph). He also rarely threw a Change (83mph).
In 2022, compared to other RHP:
His slider comes in below hitting speed, sweeps across the zone and has exceptional depth. His sinker has heavy sinking action, has an obvious tail, results in somewhat more flyballs compared to other pitchers' sinkers and has slightly below average velo. His fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has heavy sinking action, has below average velo and has slight armside run. His change (take this with a grain of salt because he's only thrown 8 of them in 2022) dives down out of the zone, results in more flyballs compared to other pitchers' changeups and has slight armside fade.
