Kansas City Royals
James McArthur has thrown 2,279 pitches that have been tracked by the PITCHf/x system between 2022 and 2024, including pitches thrown in the MLB Regular Season and Spring Training. In 2024, they have relied primarily on their Sinker (95mph), Curve (84mph) and Slider (88mph), also mixing in a Fourseam Fastball (95mph). He also rarely throws a Cutter (94mph).
In 2024, compared to other RHP:
Their sinker has an obvious tail, results in many more groundballs compared to other pitchers' sinkers, has well above average velo and has some natural sinking action. Their curve is thrown extremely hard, has a sharp downward bite and has slight glove-side movement. Their slider generates more whiffs/swing compared to other pitchers' sliders, is much harder than usual and has primarily 12-6 movement. Their fourseam fastball has some natural sinking action, has slight armside run and has slightly above average velo. Their cutter (take this with a grain of salt because they've only thrown 1 of them in 2024) is thrown at a speed that's borderline unfair, is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters, has surprisingly little cutting action and has some natural sink.
