His sinker has some natural sinking action. His fourseam fastball has some natural sinking action, has essentially average velo and results in somewhat more groundballs compared to other pitchers' fourseamers. His cutter has some natural sink and has strong cutting action. His change is a real worm killer that generates an extreme number of groundballs compared to other pitchers' changeups, generates fewer whiffs/swing compared to other pitchers' changeups and has some natural sink to it. His curve results in somewhat more flyballs compared to other pitchers' curves.
