Chicago White Sox
Although they have not thrown an MLB pitch in 2023, José Ruiz threw 3,114 pitches that were tracked by the PITCHf/x system between 2017 and 2022, including pitches thrown in the MLB Regular Season and Spring Training. In 2022, they relied primarily on their Fourseam Fastball (97mph), Curve (86mph) and Change (90mph). He also rarely threw a Sinker (96mph).
In 2022, compared to other RHP:
His fourseam fastball is blazing fast, generates more whiffs/swing compared to other pitchers' fourseamers and results in somewhat more flyballs compared to other pitchers' fourseamers. His curve is thrown extremely hard, has primarily 12-6 movement, generates more whiffs/swing compared to other pitchers' curves and has little depth. His change is thrown extremely hard, results in somewhat more groundballs compared to other pitchers' changeups and has slight armside fade. His sinker (take this with a grain of salt because he's only thrown 4 of them in 2022) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers and is blazing fast.
