Backing up an opening 66 with an eight-birdie, no-bogey 62, Jimmy Walker took a one-stroke lead at 12 under par. Defending champion Webb Simpson looked good as well but couldn’t quite keep pace with Walker.
Carl Pettersson and Sergio Garcia were tied for third with two others two stokes off the lead.
When the horn blew for a weather delay, Garcia, who is trying to make the European Ryder Cup team, matched Simpson for the third-lowest round of the day, a bogey-free 63.
Walker is currently in 55th place for the FedEx Cup playoffs but is still looking for his first PGA Tour win after a strong career in the Nationwide Tour years ago.
Pettersson, a native of Sweden who has lived for many years in North Carolina, continued his strong play of late. Last week he finished T-3 in the PGA Championship at Kiawah Island, S.C, and he opened this tournament with a 62 on Thursday.
Simpson, who made this tournament his first PGA Tour win last year and won the U.S. Open this year, birdied four of his last five holes to move near the lead.
