In 2024, compared to other LHP:
Their fourseam fastball is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, has less armside movement than typical, has some natural sinking action and has essentially average velo. Their splitter has surprising cut action, is an extreme flyball pitch compared to other pitchers' splitters and has some natural sink to it. Their curve has an exceptional bite, results in somewhat more flyballs compared to other pitchers' curves, has slight glove-side movement and has slightly below average velo. Their cutter has heavy sink, results in more flyballs compared to other pitchers' cutters, has slightly below average velo and has strong cutting action. Their slider has exceptional depth and results in somewhat more flyballs compared to other pitchers' sliders. Their change (take this with a grain of salt because they've only thrown 2 of them in 2024) is basically never swung at and missed compared to other pitchers' changeups, has surprising cut action, is an extreme flyball pitch compared to other pitchers' changeups, is much firmer than usual and has a lot of backspin.
