In 2022, compared to other RHP:
His slider is a prototypical pitch with few remarkable qualities. His sinker has heavy sinking action, has an obvious tail and generates fewer whiffs/swing compared to other pitchers' sinkers. His curve has very little depth, has sweeping glove-side movement, results in more flyballs compared to other pitchers' curves and has slightly below average velo. His splitter has dives down out of the zone, is an extreme flyball pitch compared to other pitchers' splitters and generates fewer whiffs/swing compared to other pitchers' splitters. His fourseam fastball has heavy sinking action, has an obvious tail, generates more whiffs/swing compared to other pitchers' fourseamers, results in more flyballs compared to other pitchers' fourseamers and has essentially average velo.
