Although they have not thrown an MLB pitch in 2023, Garrett Stubbs threw 60 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 (83mph) and Curve (47mph).
In 2022, compared to other RHP:
His fourseam fastball comes in below hitting speed, generates fewer whiffs/swing compared to other pitchers' fourseamers, has some natural sinking action and has slight armside run. His curve (take this with a grain of salt because he's only thrown 15 of them in 2022) comes in below hitting speed, has very little depth, is basically never swung at and missed compared to other pitchers' curves and has primarily 12-6 movement.
