The Cincinnati Reds like their chances when Hunter Greene is on the mound. The 6-foot-5 right-hander has one of baseball’s best fastballs, to go along with a nasty slider. But keeping him on the mound has been a challenge. Going into his fifth year in the majors, Greene added more lower-half strengthening exercises to his offseason routine. He says he wants to pile up more innings and make all his starts. The end result of Greene’s pursuit of increased durability could go a long way to determining the course of the Reds’ season.
