Virginia Beach Open winner Troy Matteson and Roger Tambellini, who was runner-up to Jason Gore at last week's Cox Classic, both fired rounds of 7-under- par 65. They were joined in a tie for third place by Brent Schwarzrock, Kevin Johnson and Jason Dufner.
Haas began his round on the back nine at Highland Springs Country Club. He birdied the par-5 11th. After three straights pars, the Wake Forest alum sank a birdie try on the par-3 15th.
The 23-year-old made it two straight as he birdied the 16th. Haas made the turn at minus-5 as he ran in an eagle putt on the par-5 18th.
Haas, whose best finish on tour was a tie for second at the 2005 Scholarship America Showdown, birdied the second. After three pars, he drained a birdie putt on the par-3 sixth. Haas closed with a birdie on the eighth to share the lead.
'The greens are really soft, the fairways are perfect and as good as these guys are, there will be a lot of low numbers shot,' Haas said. 'It's fun, but then again, we did it last week. I shot 17-under last week and barely finished in the top-10.'
Weatherly, a playoff loser to Jason Schultz earlier this year in Chattanooga, also started his round on the back nine and got off to a hot start. He birdied the 10th and then eagled the par-5 11th to quickly move to minus-3.
The 27-year-old then dropped in a birdie putt on the 15th. He also made the turn at minus-5 thanks to a birdie on No. 18.
Weatherly kept rolling on the front side. He made it two in a row as he birdied the par-5 first. Weatherly birdied the second and third to get to minus-8. After four straight birdies, he closed with six pars in a row.
'The greens are pretty soft and receptive,' said Weatherly, who ranks 41st on the Nationwide Tour money list. 'I haven't played that well early in the morning this year. I decided to get up a bit earlier, get the body moving earlier and see if that didn't help.'
Henrico County Open winner Chad Collins, Knoxville Open champion Kim Felton and Eric Axley, winner at The Rex Hospital Open, are tied for eighth at 6-under-par 66. They are joined there by Kris Blanks, Rich Morris, Scott Petersen, Anthony Rodriguez, Jon Rusk, Jerry Smith and Rick Fehr. There are 21 more players just one shot back at minus-5.
