Pittsburgh Pirates
Although they have not thrown an MLB pitch in 2025, Isiah Kiner-Falefa threw 68 pitches that were tracked by the PITCHf/x system between 2023 and 2024, all of them occuring in the MLB Regular Season. In 2024, they relied primarily on their Fourseam Fastball (68mph).
In 2024, compared to other RHP:
Their fourseam fastball (take this with a grain of salt because they've only thrown 18 of them in 2024) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' fourseamers, has much less armside movement than typical, results in more flyballs compared to other pitchers' fourseamers and has some natural sinking action.
