Bubba Watson and Kris Cox shared the opening round lead but each player managed only rounds of 72 on Friday. They were joined by Brandt Snedeker, Richard S. Johnson, Jason Schultz, Ryan Hietala and Kyle Thompson at 7-under-par 137.
Brehaut started on the back side at Le Triomphe Golf & Country Club and jumped out of the gate with a birdie at the par-4 10th. He then ran off three consecutive birdies from the par-5 14th to move to 7 under.
The 41-year-old added a birdie at the par-4 second. At the par-5 fifth, Brehaut hit his third shot within 40 feet of the hole and drained the long birdie putt.
'I made four pretty long putts today,' Brehaut said. 'When you make a few of those you don't expect to make, that is what leads to good scoring.'
Brehaut then converted a 25-foot putt for a birdie at the par-3 eighth but stumbled coming home with a bogey at the ninth.
'I played pretty solid except for the last hole,' said Brehaut, a two-time champion on the Nationwide Tour. 'The wind wasn't really doing anything until the last couple of holes.'
Veazey, who captured the season-opening BellSouth Panama Championship, collected six birdies and a bogey for a round of 67. Standly had three birdies for a bogey-free 69 while Lunde used five birdies and a bogey for a 68.
Wetterich, who was in contention at The Honda Classic on the PGA Tour two weeks ago, played the back nine first and picked up three birdies over his first six holes.
The 31-year-old birdied the par-4 second but found trouble with a bogey at the fourth. Wetterich recovered well with an eagle at the par-5 fifth only to drop another shot with a bogey at the sixth on his way to a 68.
Tom Scherrer, Joel Kribel, Steve Pleis, Tim O'Neal and 2002 U.S. Amateur champion Ricky Barnes are knotted at 6-under-par 138.
The 36-hole cut fell at 1-under-par 143 with 68 players qualifying for the weekend.
