Backing up an opening 66 with an eight-birdie, no-bogey 62, Jimmy Walker took a one-stroke lead at 12 under par over defending champion Webb Simpson late in the second round of the Wyndham Championship in Greensboro, N.C.
Carl Pettersson, Sergio Garcia, Tim Clark and Harris English were tied for third, two strokes off the lead, when the horn blew for a weather delay at Sedgefield Country Club. 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. Tim Herron had a 9-under 61 after opening with a 76.
Walker, 33, a native of Oklahoma and a resident of Texas, is still looking for his first PGA Tour win. He is safely in place for making the FedEx Cup playoffs, currently standing 55th.
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.
