Spencer Arrighetti has thrown 4,391 pitches that have been tracked by the PITCHf/x system between 2023 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Fourseam Fastball (93mph) and Cutter (87mph), also mixing in a Curve (78mph), Change (85mph) and Slider (80mph). He also rarely throws a Sinker (92mph).
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 has slight armside run. Their cutter generates an extremely high number of swings & misses compared to other pitchers' cutters, has some natural sink and has strong cutting action. Their curve has sweeping glove-side movement and generates more whiffs/swing compared to other pitchers' curves. Their change dives down out of the zone, generates a very high amount of groundballs compared to other pitchers' changeups and has slight armside fade. Their slider comes in below hitting speed, sweeps across the zone, generates a high number of swings & misses compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders and has some two-plane movement. Their sinker (take this with a grain of salt because they've only thrown 18 of them in 2025) generates an extremely high number of swings & misses compared to other pitchers' sinkers and has an obvious tail.
