Jon Corey Hart (born March 24, 1982) is an American baseball outfielder for the Milwaukee Brewers.
Prior to being drafted in the 11th round of the 2000 MLB Draft, Hart played for the Greenwood High School Gators in Bowling Green, Kentucky. Hart also played basketball for four years for the Gators for Coach Jason Couch. On the diamond, he played nearly every position, routinely in the middle infield and even pitching in relief. Hart's jersey is retired by Greenwood and hangs from the rafters in the school's gymnasium.
Hart started his career in 2000 with the Rookie League Ogden Raptors, primarily playing at first base. He moved up to the single-A High Desert Mavericks and then the double-A Huntsville Stars by the 2002 season; defensive problems caused Hart to be moved to the outfield. Playing there, he moved up to the Class AAA Indianapolis Indians by 2004.
