 Young 's mid @-@ 2000s repertoire included fastballs , curveballs , sliders and changeups . His curveball is a slow curveball and his 85 miles per hour ( 137 km / h ) fastball has been described by former teammate and catcher Mike Piazza as having late life and late movement that seems to jump . His curveball is used to keep the hitters off balance so that they do not jump on his low @-@ velocity fastball . Former Ranger pitching coach Orel Hershiser says Young has the ability to throw his fastball to all locations effectively which gives him a chance at success . Hershiser describes Young 's pitches as sneaky fast because his methodical delivery and size give him deception . This delivery has also left him susceptible to stolen bases due to the relatively long time it takes for him to deliver a pitch from the stretch . By 2012 , nearly all of his pitches were fastballs or sliders .
