Chicago White Sox
Although they have not thrown an MLB pitch in 2024, Donn Roach threw 950 pitches that were tracked by the PITCHf/x system between 2011 and 2016, including pitches thrown in the MLB Regular Season and Spring Training. In 2016, they relied primarily on their Sinker (92mph), also mixing in a Curve (78mph) and Splitter (87mph). He also rarely threw a Fourseam Fastball (92mph).
In 2016, compared to other RHP:
Their sinker is basically never swung at and missed compared to other pitchers' sinkers, results in many more groundballs compared to other pitchers' sinkers and has some natural sinking action. Their curve (take this with a grain of salt because they've only thrown 18 of them in 2016) is basically never swung at and missed compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves and has slight glove-side movement. Their splitter (take this with a grain of salt because they've only thrown 14 of them in 2016) is an extreme flyball pitch compared to other pitchers' splitters, generates fewer whiffs/swing compared to other pitchers' splitters, is much 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 2 of them in 2016) has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers and has essentially average velo.
