Cincinnati Reds
Although they have not thrown an MLB pitch in 2024, Barrett Astin threw 148 pitches that were tracked by the PITCHf/x system in 2017, all of them occuring in the MLB Regular Season. In 2017, they relied primarily on their Sinker (92mph), also mixing in a Slider (87mph), Change (86mph) and Fourseam Fastball (92mph).
In 2017, compared to other RHP:
Their sinker has heavy sinking action, is basically never swung at and missed compared to other pitchers' sinkers and results in many more groundballs compared to other pitchers' sinkers. Their slider is much harder than usual, has less than expected depth, has primarily 12-6 movement and results in somewhat more groundballs compared to other pitchers' sliders. Their change is basically never swung at and missed compared to other pitchers' changeups, is slightly firmer than usual and has some natural sink to it. Their fourseam fastball (take this with a grain of salt because they've only thrown 19 of them in 2017) has heavy sinking action, generates fewer whiffs/swing compared to other pitchers' fourseamers, has essentially average velo and results in somewhat more groundballs compared to other pitchers' fourseamers.
