Arizona Diamondbacks
Although they have not thrown an MLB pitch in 2025, Grae Kessinger threw 11 pitches that were tracked by the PITCHf/x system in 2024, all of them occuring in the MLB Regular Season. In 2024, they relied primarily on their Fourseam Fastball (75mph).
In 2024, compared to other RHP:
Their fourseam fastball (take this with a grain of salt because they've only thrown 11 of them in 2024) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' fourseamers, has less armside movement than typical, results in more flyballs compared to other pitchers' fourseamers and has some natural sinking action.
