John Marzano was found dead this afternoon in his home on Passyunk Avenue, reports 6ABC. The South Philadelphia native Central High School and Temple University ballplayer was 45. According to 6ABC's Bob Monek, a relative of Marzano called police to break down a door where Marzano apparently had fallen. It is unclear at this time whether the former 1984 Olympic team member died from the fall or had suffered a heart attack first, the report says. Marzano played for the Boston Red Sox, Texas Rangers and the Seattle Mariners, and in the minors with the Phillies and Cleveland Indians. Marzano worked for two years on Comcast SportsNet as an analyst on "Phillies Post Game Live" and was formerly a host on Sportsradio 610 WIP. More recently, Marzano worked for MLB.com, hosting a show along with Vinny Micucci.
