Marzano, known as "Johnny Marz," died in April at the age of 45. He was from Philadelphia and had been working for Major League Baseball's Web site, where he co-hosted a show on weekday mornings.
Before joining MLB's Web site, Marzano was a baseball analyst on Comcast SportsNet for the station's Philadelphia Phillies postgame shows. He had also appeared regularly on WIP-AM, a sports radio station.
A graduate of Temple University, Marzano earned a spot as a catcher on the 1984 U.S. Olympic team that included future major league stars Mark McGwire, Barry Larkin and Will Clark. He was drafted by the Boston Red Sox with the 14th overall pick in the first round of the 1984 amateur draft.
Marzano played 10 seasons in the big leagues for the Red Sox, Texas Rangers and Seattle Mariners before retiring in 1998. He also played in the minors for the Phillies and the Cleveland Indians.
Marzano is survived by his wife, Terri, daughters Dominique and Danielle, and two grandchildren.
