Provus grew up in Highland Park, Illinois and attended Syracuse University. He began his major league broadcasting career as the pregame/postgame host for radio broadcasts of the Chicago Cubs and backed up Pat Hughes. The Milwaukee Brewers then hired Provus in 2009, replacing Jim Powell who departed for a job with the Atlanta Braves, alongside Bob Uecker until 2012. Joe Block would replace him.
The Twins hired Provus to replace John Gordon who retired after the 2011 season. He also called collegiate football, basketball, and baseball games for the Virginia Tech Hokies, Georgia Tech Yellow Jackets, UAB Blazers, and the Wake Forest Demon Deacons. He also did play by play and studio hosting for the Syracuse Orangemen football, basketball, and lacrosse. Cory is a play-by-play announcer for a small package of Big Ten Network games and is a play-by-play announcer for college basketball on FOX.
