Non-MLB
Luis Guerrero has thrown 2,180 pitches that have been 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 have relied primarily on their Slider (84mph) and Fourseam Fastball (97mph), also mixing in a Change (87mph). He also rarely throws a Sinker (98mph).
In 2025, compared to other RHP:
Their slider has short glove-side cut, results in somewhat more flyballs compared to other pitchers' sliders and has some two-plane movement. Their fourseam fastball has well above average velo. Their change has an obvious armside fade, is much firmer than usual, results in somewhat more flyballs compared to other pitchers' changeups and has some natural sink to it. Their sinker (take this with a grain of salt because they've only thrown 1 of them in 2025) is basically never swung at and missed compared to other pitchers' sinkers, is thrown at a speed that's borderline unfair, is an extreme flyball pitch compared to other pitchers' sinkers and has slight armside run.
