Josh Williams is alone in third place after an opening-round, 5-under 65. Brock Mackenzie shot a 4-under-par 66 and has fourth at minus-4.
There was a weather delay on Thursday that lasted nearly 90 minutes, but the entire field was able to complete the first round.
Driscoll started on the 10th tee and collected his first birdie at the short, par-4 12th. He drained a 15-footer there and kicked in a 3-foot birdie putt at the 16th to make the turn at 2-under 33.
At the par-5 third, Driscoll roped a 7-iron from 200 yards out to 7 feet. He converted the eagle putt to reach 4 under par, but did not waste time getting to minus-five. The 2004 Virginia Beach Open winner rolled in a 50-footer for birdie at the par-3 fourth.
Driscoll parred his next four holes. He joined the lead thanks to his play at the par-five ninth, even though he missed the green with his second. Driscoll chipped his third to 14 feet and holed it for a round of 64.
'I had some putts go in that I didn't expect,' admitted Driscoll. 'It was a solid round. There are some birdie holes, but there aren't many. Pars will be hard to come by.'
Haas had a much more interesting start than his fellow co-leader. Haas birdied the 10th, his first, bogeyed 11, then birdied 12. He soared up the leaderboard with back-to-back birdies from the 15th, both from 7 feet.
Haas opened with a 12-foot birdie putt at the first and ran home a 12-foot eagle putt at No. 4. He could not save par from a bunker at four, but tapped in a short birdie putt at the short, par-3 sixth.
At the par-four eighth, Haas missed the green with his second shot. He did not get up and down for par, but reclaimed his share of the lead with a tap-in birdie at the par-5 ninth.
'I kept the ball in the fairway. A good shot is rewarded and a bad shot is penalized,' said Haas, who missed the cut in more than half his starts since the beginning of July. 'I hit a bunch of good putts, but I missed a couple too.'
Jess Daley, David Mathis, Todd Demsey, Jason Allred, David Hearn and Mark Wiebe are knotted in fifth place at 3-under-par 67
