Boston Red Sox
Although they have not thrown an MLB pitch in 2024, Bobby Poyner threw 599 pitches that were tracked by the PITCHf/x system between 2018 and 2019, all of them occuring in the MLB Regular Season. In 2019, they relied primarily on their Fourseam Fastball (89mph), also mixing in a Change (82mph) and Slider (83mph). He also rarely threw a Curve (77mph).
In 2019, compared to other LHP:
Their fourseam fastball generates a high number of swings & misses compared to other pitchers' fourseamers, results in somewhat more flyballs compared to other pitchers' fourseamers, has slightly below average velo and has slightly less natural movement than typical. Their change is an extreme flyball pitch compared to other pitchers' changeups and has a lot of backspin. Their slider results in somewhat more flyballs compared to other pitchers' sliders. Their curve (take this with a grain of salt because they've only thrown 2 of them in 2019) is basically never swung at and missed compared to other pitchers' curves and is an extreme flyball pitch compared to other pitchers' curves.
