Pitch Repertoire At-A-Glance

Guillo Zuñiga has thrown 2,457 pitches that have been tracked by the PITCHf/x system between 2022 and 2026, including pitches thrown in the MLB Regular Season, The World Baseball Classic and Spring Training. In 2026, they have relied primarily on their Slider (87mph), Fourseam Fastball (97mph) and Sinker (97mph), also mixing in a Change (88mph).


In 2026, compared to other RHP:
Their slider results in more flyballs compared to other pitchers' sliders and is much harder than usual. Their fourseam fastball has heavy sinking action, is blazing fast and generates fewer whiffs/swing compared to other pitchers' fourseamers. Their sinker is thrown at a speed that's borderline unfair, results in more flyballs compared to other pitchers' sinkers, has slight armside run and has some natural sinking action. Their change (take this with a grain of salt because they've only thrown 10 of them in 2026) dives down out of the zone, generates more whiffs/swing compared to other pitchers' changeups, is much firmer than usual and results in more flyballs compared to other pitchers' changeups.
