The move frees up the casino's current president, Bob Boughner, to assume a larger role with parent company Boyd Gaming. Boughner has done double duty for the past four years as an executive with Las Vegas-based Boyd while also overseeing the Borgata as its president.

Ballance worked for Borgata for years before it opened in 2003 as the casino's vice president of development. Before that, he worked for 17 years at Harrah's Resort Atlantic City.

The Borgata is Atlantic City's top casino in terms of monthly gambling revenue. It took in $55.3 million in September, more than $20 million better than its next closest competitor.
