In 2023, they relied primarily on their Sinker using a Two-seam Fastball grip (92mph) and Cutter (88mph), also mixing in a Fourseam Fastball (92mph), Curve (77mph) and Splitter (83mph).
In 2023, compared to other RHP:
Their sinker using a two-seam fastball grip is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers and generates fewer whiffs/swing compared to other pitchers' sinkers. Their cutter is an extreme flyball pitch compared to other pitchers' cutters and has little cutting action. Their fourseam fastball is basically never swung at and missed compared to other pitchers' fourseamers, results in more flyballs compared to other pitchers' fourseamers, has essentially average velo and has slight armside run. Their curve generates a high number of swings & misses compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves and has primarily 12-6 movement. Their splitter has movement that suggests a lot of backspin, results in somewhat more flyballs compared to other pitchers' splitters, has slight armside fade and has slightly below average velo.
