Detroit Tigers
Although they have not thrown an MLB pitch in 2024, Trevor Rosenthal threw 7,229 pitches that were tracked by the PITCHf/x system between 2012 and 2023, including pitches thrown in the MLB Regular Season, the MLB Postseason and Spring Training. In 2023, they relied primarily on their Fourseam Fastball (93mph) and Slider (86mph), also mixing in a Change using a Circle Change grip (85mph).
In 2023, compared to other RHP:
Their fourseam fastball is basically never swung at and missed compared to other pitchers' fourseamers, has essentially average velo and results in somewhat more flyballs compared to other pitchers' fourseamers. Their slider is an extreme flyball pitch compared to other pitchers' sliders. Their change using a circle change grip (take this with a grain of salt because they've only thrown 10 of them in 2023) is basically never swung at and missed compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups, has a lot of backspin and is slightly firmer than usual.
