Jay Jackson has thrown 1,138 pitches that have been tracked by the PITCHf/x system between 2012 and 2022, including pitches thrown in the MLB Regular Season and Spring Training. In 2022, they have relied primarily on their Slider (84mph) and Fourseam Fastball (92mph).
In 2022, compared to other RHP:
His slider is an extreme flyball pitch compared to other pitchers' sliders and generates more whiffs/swing compared to other pitchers' sliders. His fourseam fastball (take this with a grain of salt because he's only thrown 15 of them in 2022) is basically never swung at and missed compared to other pitchers' fourseamers and has essentially average velo.
