Their curve (take this with a grain of salt because they've only thrown 1 of them in 2024) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves, has little depth and has primarily 12-6 movement.
