Pittsburgh Pirates
Peter Strzelecki has thrown 3,087 pitches that have been tracked by the PITCHf/x system between 2022 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Fourseam Fastball (94mph) and Slider (82mph), also mixing in a Change (84mph) and Sinker (93mph). He also rarely throws a Curve (81mph).
In 2025, compared to other RHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has some natural sinking action, has essentially average velo and results in somewhat more groundballs compared to other pitchers' fourseamers. Their slider sweeps across the zone, is an extreme flyball pitch compared to other pitchers' sliders, generates more whiffs/swing compared to other pitchers' sliders, has below average velo and has some two-plane movement. Their change has an obvious armside fade, dives down out of the zone and results in more flyballs compared to other pitchers' changeups. Their sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, results in more flyballs compared to other pitchers' sinkers, has slight armside run, has slightly above average velo and has some natural sinking action. Their curve (take this with a grain of salt because they've only thrown 13 of them in 2025) is basically never swung at and missed compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves, is slightly harder than usual and has slight glove-side movement.
