Arizona Diamondbacks
Although they have not thrown an MLB pitch in 2023, Carson Kelly threw 80 pitches that were tracked by the PITCHf/x system between 2020 and 2022, all of them occuring in the MLB Regular Season. In 2022, they relied primarily on their Fourseam Fastball (61mph).
In 2022, compared to other RHP:
Their fourseam fastball comes in below hitting speed, is basically never swung at and missed compared to other pitchers' fourseamers, has less armside movement than typical and results in somewhat more flyballs compared to other pitchers' fourseamers.
