Non-MLB
Although they have not thrown an MLB pitch in 2024, Javy Guerra threw 5,297 pitches that were tracked by the PITCHf/x system between 2010 and 2021, including pitches thrown in the MLB Regular Season, the MLB Postseason and Spring Training. In 2021, they relied primarily on their Fourseam Fastball (92mph) and Cutter (88mph), also mixing in a Curve (78mph) and Sinker (91mph). He also rarely threw a Change (82mph).
In 2021, compared to other RHP:
Their fourseam fastball has much less armside movement than typical and has slightly below average velo. Their cutter generates fewer whiffs/swing compared to other pitchers' cutters, has some natural sink and has strong cutting action. Their curve (take this with a grain of salt because they've only thrown 15 of them in 2021) is basically never swung at and missed compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves and has primarily 12-6 movement. Their sinker (take this with a grain of salt because they've only thrown 13 of them in 2021) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has surprisingly little armside run and has little sinking action compared to a true sinker. Their change (take this with a grain of salt because they've only thrown 6 of them in 2021) has surprising cut action, results in more flyballs compared to other pitchers' changeups and has a lot of backspin.
