Detroit Tigers
Although they have not thrown an MLB pitch in 2024, A.J. Achter threw 959 pitches that were tracked by the PITCHf/x system between 2014 and 2016, including pitches thrown in the MLB Regular Season and Spring Training. In 2016, they relied primarily on their Change (83mph) and Fourseam Fastball (92mph), also mixing in a Sinker (91mph) and Slider (82mph). He also rarely threw a Cutter (90mph).
In 2016, compared to other RHP:
Their change has surprising cut action and results in somewhat more groundballs compared to other pitchers' changeups. Their fourseam fastball has less armside movement than typical, has essentially average velo and results in somewhat more flyballs compared to other pitchers' fourseamers. Their sinker generates more whiffs/swing compared to other pitchers' sinkers and results in more flyballs compared to other pitchers' sinkers. Their slider is basically never swung at and missed compared to other pitchers' sliders, has less than expected depth and results in somewhat more groundballs compared to other pitchers' sliders. Their cutter (take this with a grain of salt because they've only thrown 1 of them in 2016) explodes on the hitter, is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters, has surprisingly little cutting action and has slightly above average velo.
