Monday's Pro-Am allows professional golfers to tee it up with the amateurs, who pay to play in the tournament.
Proceeds from the Pro-Am go to benefit area charities.
2012's Greenbrier Classic Champ Ted Potter Jr. says playing in Monday's tournament allows him the chance to prepare for tournament play.
I definitely like my chances this week, winning here in 2012 and last year finishing in the top 30," Potter said. "I definitely like the course a lot. I really enjoy being here."
Monday's Pro-Am is taking place on the Old White TPC Course.
Wednesday, even more of the big name pros will hit the links with some big celebrities including Willie and Jase Robertson from A&E Television's Duck Dynasty, NASCAR driver Denny Hamlin and Lady Antebellum lead singer Charles Kelley.
