Arizona Diamondbacks
Although they have not thrown an MLB pitch in 2025, Pavin Smith threw 17 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 (74mph).
In 2024, compared to other LHP:
Their fourseam fastball (take this with a grain of salt because they've only thrown 17 of them in 2024) comes in below hitting speed, has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers and results in somewhat more groundballs compared to other pitchers' fourseamers.
