Toronto Blue Jays
Although they have not thrown an MLB pitch in 2023, Whit Merrifield threw 13 pitches that were tracked by the PITCHf/x system in 2022, all of them occuring in the MLB Regular Season. In 2022, they relied primarily on their Fourseam Fastball (60mph).
In 2022, compared to other RHP:
His fourseam fastball (take this with a grain of salt because he's only thrown 13 of them in 2022) comes in below hitting speed, has heavy sinking action, has an obvious tail and generates a high number of swings & misses compared to other pitchers' fourseamers.
