Their fourseam fastball generates a very high amount of groundballs compared to other pitchers' fourseamers, has some natural sinking action and has essentially average velo. Their change is slightly firmer than usual, results in somewhat more groundballs compared to other pitchers' changeups, has slight armside fade and has some natural sink to it. Their sinker is basically never swung at and missed compared to other pitchers' sinkers and is an extreme flyball pitch compared to other pitchers' sinkers.
