In 2023, compared to other RHP:
Their fourseam fastball has essentially average velo and results in somewhat more flyballs compared to other pitchers' fourseamers. Their curve generates fewer whiffs/swing compared to other pitchers' curves, has a sharp downward bite and results in somewhat more flyballs compared to other pitchers' curves. Their slider is a prototypical pitch with few remarkable qualities. Their change results in more flyballs compared to other pitchers' changeups, is slightly firmer than usual, has slight armside fade and has some natural sink to it. Their splitter is basically never swung at and missed compared to other pitchers' splitters and is an extreme flyball pitch compared to other pitchers' splitters. Their cutter (take this with a grain of salt because they've only thrown 12 of them in 2023) is an extreme flyball pitch compared to other pitchers' cutters, has little cutting action and has slightly above average velo. Their sinker (take this with a grain of salt because they've only thrown 1 of them in 2023) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has little sinking action compared to a true sinker and has slightly above average velo.
