In 2024, they have relied primarily on their Slider (88mph) and Fourseam Fastball (98mph), also mixing in a Sinker (97mph). He also rarely throws a Curve (80mph).
In 2024, compared to other RHP:
Their slider has exceptional depth and is much harder than usual. Their fourseam fastball is thrown at a speed that's borderline unfair, is an extreme flyball pitch compared to other pitchers' fourseamers and has less armside movement than typical. Their sinker is basically never swung at and missed compared to other pitchers' sinkers, is thrown at a speed that's borderline unfair, is an extreme flyball pitch compared to other pitchers' sinkers and has less armside run than typical. Their curve (take this with a grain of salt because they've only thrown 4 of them in 2024) is basically never swung at and missed compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves and has a sharp downward bite.
