Pittsburgh Pirates
Although they have not thrown an MLB pitch in 2026, Evan Sisk threw 3,325 pitches that were tracked by the PITCHf/x system between 2021 and 2025, including pitches thrown in the MLB Regular Season, Spring Training and Fall/Winter Ball. In 2025, they relied primarily on their Sinker (91mph) and Slider (80mph), also mixing in a Fourseam Fastball (91mph), Cutter (89mph) and Curve (77mph). He also rarely threw a Change (87mph).
In 2025, compared to other LHP:
Their sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, has heavy sinking action, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers and has less armside run than typical. Their slider sweeps across the zone, generates more whiffs/swing compared to other pitchers' sliders and has less than expected depth. Their fourseam fastball has heavy sinking action, generates fewer whiffs/swing compared to other pitchers' fourseamers, has less armside movement than typical and has essentially average velo. Their cutter has well above average velo, results in somewhat more groundballs compared to other pitchers' cutters, has some natural sink and has strong cutting action. Their curve has sweeping glove-side movement. Their change (take this with a grain of salt because they've only thrown 1 of them in 2025) is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' changeups, dives down out of the zone and is an extreme flyball pitch compared to other pitchers' changeups.
