Their fourseam fastball is basically never swung at and missed compared to other pitchers' fourseamers, is straight as an arrow, has some natural sinking action, has essentially average velo and results in somewhat more groundballs compared to other pitchers' fourseamers. Their change generates an extremely high number of swings & misses compared to other pitchers' changeups, is much firmer than usual, results in more flyballs compared to other pitchers' changeups and has some natural sink to it.
