Their splitter is a real worm killer that generates an extreme number of groundballs compared to other pitchers' splitters, is basically never swung at and missed compared to other pitchers' splitters, has slight cut action, has some natural sink to it and is slightly firmer than usual. Their fourseam fastball generates more whiffs/swing compared to other pitchers' fourseamers, has less armside movement than typical, results in many more groundballs compared to other pitchers' fourseamers and has essentially average velo.
