Javy Guerra has thrown 2,656 pitches that have been tracked by the PITCHf/x system between 2019 and 2026, including pitches thrown in the MLB Regular Season, The World Baseball Classic, Spring Training and Fall/Winter Ball. In 2026, they have relied primarily on their Fourseam Fastball (97mph) and Slider (87mph), also mixing in a Splitter (89mph) and Sinker (97mph). He also rarely throws a Change (89mph).
In 2026, compared to other RHP:
Their fourseam fastball generates more whiffs/swing compared to other pitchers' fourseamers, has some natural sinking action, has well above average velo and results in somewhat more flyballs compared to other pitchers' fourseamers. Their slider generates fewer whiffs/swing compared to other pitchers' sliders, has short glove-side cut, is much harder than usual and results in somewhat more flyballs compared to other pitchers' sliders. Their splitter is thrown extremely hard, results in somewhat more flyballs compared to other pitchers' splitters and has slight armside fade. Their sinker is thrown at a speed that's borderline unfair, has an obvious tail, is an extreme flyball pitch compared to other pitchers' sinkers and has some natural sinking action. Their change (take this with a grain of salt because they've only thrown 1 of them in 2026) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups, has slight armside fade and has some natural sink to it.
