Atlanta Braves
Although they have not thrown an MLB pitch in 2024, Orlando Arcia threw 40 pitches that were tracked by the PITCHf/x system between 2020 and 2022, all of them occuring in the MLB Regular Season. In 2022, they relied primarily on their Change (49mph), also mixing in a Fourseam Fastball (84mph).
In 2022, compared to other RHP:
Their change (take this with a grain of salt because they've only thrown 8 of them in 2022) comes in below hitting speed, has surprising cut action, generates fewer whiffs/swing compared to other pitchers' changeups and results in more flyballs compared to other pitchers' changeups. Their fourseam fastball (take this with a grain of salt because they've only thrown 2 of them in 2022) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has some natural sinking action and has slightly less natural movement than typical.
