Hall of Fame broadcaster Joe Garagiola is calling it a career. The 87-year-old St. Louis native formally announced his retirement Wednesday after 57 years in the business. Garagiola spent the last 15 seasons doing select television broadcasts for the Arizona Diamondbacks. He played nine seasons in the majors as a catcher in the 1940's and 50's. Garagiola went into broadcasting after his playing days in 1955, calling St. Louis Cardinals games on radio before going on to a long career with NBC.
