Non-MLB
Although they have not thrown an MLB pitch in 2024, Zac Reininger threw 1,092 pitches that were tracked by the PITCHf/x system between 2017 and 2019, all of them occuring in the MLB Regular Season. In 2019, they relied primarily on their Fourseam Fastball (95mph), Sinker (93mph) and Slider (84mph), also mixing in a Curve (81mph). He also rarely threw a Change (85mph).
In 2019, compared to other RHP:
Their fourseam fastball has essentially average velo. Their sinker generates fewer whiffs/swing compared to other pitchers' sinkers, results in somewhat more flyballs compared to other pitchers' sinkers and has slight armside run. Their slider is basically never swung at and missed compared to other pitchers' sliders, results in more flyballs compared to other pitchers' sliders, has short glove-side cut and has some two-plane movement. Their curve is a prototypical pitch with few remarkable qualities. Their change (take this with a grain of salt because they've only thrown 1 of them in 2019) is basically never swung at and missed compared to other pitchers' changeups and results in more flyballs compared to other pitchers' changeups.
