3 tied for lead in BMW Charity Pro-Am
Davidson, a former player at nearby Furman, had seven birdies and two bogeys at The Reserve at Lake Keowee to match Barber and Blaum at 14-under 201.
"It's awesome. It's definitely more exciting than if it was a different tournament," Davidson said. "It was fun to play with all those people watching."
Barber, the former Auburn player coming off a victory two weeks ago in the South Georgia Classic, had a 68 at The Reserve.
"Golf is a funny game in that it doesn't satisfy you," Barber said. "It's just one of those times where I feel like I'm playing well and I'm thankful to be here."
Blaum, who played at Duke, shot a 68 at Thornblade Club -- the site of the final round.
"The goal out here is always to win," Blaum said. "I feel I've been playing well enough to win the last four or five events."
