San Francisco Giants
Although they have not thrown an MLB pitch in 2023, Donovan Walton threw 21 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 Change (37mph) and Fourseam Fastball (61mph).
In 2022, compared to other RHP:
Their change (take this with a grain of salt because they've only thrown 13 of them in 2022) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' changeups and has surprising cut action. Their fourseam fastball (take this with a grain of salt because they've only thrown 8 of them in 2022) comes in below hitting speed, has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers, has an obvious tail and is an extreme flyball pitch compared to other pitchers' fourseamers.
