John Rooney is more than the Cardinals' play-by-play radio man. He's their good-luck charm with the team winning two championships since Rooney arrived here in 2006, fresh from calling the '05 World Series victory for his former employer, the Chicago White Sox. Now eight years into his role with the Cardinals, Rooney serves as the ballast in the Cardinals' broadcast booth, dutifully setting up the stories for Mike Shannon while also keeping his chatty partner from drifting too far off course. But don't be fooled. Rooney isn't just a straight man. His decades in sports media have left him with plenty of amusing anecdotes of his own, as well as a hilarious ability to impersonate one of his early role models, Harry Caray.
