"I think it's a lot of things that makes me play well this week," said Blixt, from Sweden. "I got my family in town, my brother and my sister, a couple friends from overseas, which makes it really relaxed. We're renting a house together and just having a good time. I don't think about golf at all coming off the golf course. Just hang out with them. It's easy to think about something else when you're in Las Vegas, right?"
John Daly was 10 under after a 63, his lowest score of the year. At 132nd on the money list, the two-time major champion is trying to move into the top 125 to secure full playing privileges for next season.
Vijay Singh, Nick Watney, Chris Kirk and John Huh also were 10 under. Singh and Watney shot 66, Kirk had a 68, and Huh a 69.
Russ Cochran topped the SAS Championship leaderboard in his return from a back injury, hitting all 18 greens in regulation and shooting a 6-under 66 in Cary, N.C.
Cochran, the 2010 tournament winner, is making his first start since the U.S. Senior Open in July.
Steve Pate, Andrew Magee, Fred Funk and Jay Don Blake were a stroke back.
Defending champion Kenny Perry and Bernard Langer topped a group at 68.
