Pittsburgh Pirates
Josh Walker has thrown 1,972 pitches that have been tracked by the PITCHf/x system between 2022 and 2024, including pitches thrown in the MLB Regular Season, The World Baseball Classic and Spring Training. In 2024, they have relied primarily on their Fourseam Fastball (94mph) and Slider (83mph), also mixing in a Sinker (93mph). He also rarely throws a Change (90mph).
In 2024, compared to other LHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is straight as an arrow and has well above average velo. Their slider generates more whiffs/swing compared to other pitchers' sliders, has short glove-side cut and results in somewhat more flyballs compared to other pitchers' sliders. Their sinker is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers, generates more whiffs/swing compared to other pitchers' sinkers, has less armside run than typical, has slightly above average velo and has some natural sinking action. Their change (take this with a grain of salt because they've only thrown 2 of them in 2024) is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' changeups, is an extreme flyball pitch compared to other pitchers' changeups, has slight cut action and has some natural sink to it.
