Baltimore Orioles
Although they have not thrown an MLB pitch in 2024, Ryan McKenna threw 49 pitches that were tracked by the PITCHf/x system between 2022 and 2023, all of them occuring in the MLB Regular Season. In 2023, they relied primarily on their Change (36mph).
In 2023, compared to other RHP:
Their change (take this with a grain of salt because they've only thrown 18 of them in 2023) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' changeups, has surprising cut action and results in somewhat more groundballs compared to other pitchers' changeups.
