Pittsburgh Pirates
Wily Peralta has thrown 17,537 pitches that have been tracked by the PITCHf/x system between 2012 and 2024, including pitches thrown in the MLB Regular Season and Spring Training. In 2024, they have relied primarily on their Fourseam Fastball (92mph), Splitter (79mph) and Slider (80mph), also mixing in a Sinker (91mph).
In 2024, compared to other RHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers and has essentially average velo. Their splitter comes in below hitting speed, results in more flyballs compared to other pitchers' splitters, has movement that suggests a lot of backspin and has slight armside fade. Their slider generates an extremely high number of swings & misses compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders, has below average velo and has primarily 12-6 movement. Their sinker (take this with a grain of salt because they've only thrown 5 of them in 2024) is so slow that it is substantially gravitational, 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.
