Cleveland Guardians
Although they have not thrown an MLB pitch in 2024, Jeremy Sowers threw 4,202 pitches that were tracked by the PITCHf/x system between 2007 and 2009, all of them occuring in the MLB Regular Season. In 2009, they relied primarily on their Fourseam Fastball (88mph), also mixing in a Sinker (89mph), Change (80mph) and Slider (78mph). He also rarely threw a Curve (89mph).
In 2009, compared to other LHP:
Their fourseam fastball has below average velo, has some natural sinking action and results in somewhat more flyballs compared to other pitchers' fourseamers. Their sinker generates fewer whiffs/swing compared to other pitchers' sinkers, results in more flyballs compared to other pitchers' sinkers, has slightly below average velo and has some natural sinking action. Their change dives down out of the zone, generates fewer whiffs/swing compared to other pitchers' changeups, has slight cut action and has slightly below average velo. Their slider comes in below hitting speed, has exceptional depth, generates fewer whiffs/swing compared to other pitchers' sliders, has short glove-side cut and 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 2009) is thrown extremely hard, has very little depth, is basically never swung at and missed compared to other pitchers' curves, is an extreme flyball pitch compared to other pitchers' curves and has primarily 12-6 movement.
