July 6 (Reuters) - American Johnson Wagner moved a step closer to winning his fourth PGA Tour title by seizing a two-shot lead after Saturday's third round of the Greenbrier Classic at White Sulphur Springs in West Virginia.
One stroke off the pace overnight on a tightly bunched leaderboard, Wagner took over at the top as he fired a sparkling six-under-par 64 on a sun-splashed day at The Greenbrier's Old White Course.
The 33-year-old Texan, who played the course several times a year when he was a student at nearby Virginia Tech, mixed seven birdies with a lone bogey to post a 14-under total of 196.
"Today my goal was to go out and make as many birdies as I could, and I did that," Wagner told Golf Channel after sinking a 12-foot birdie putt at the par-three last and pumping his right fist in delight.
"Now I've got to take the same attitude into tomorrow."
Fellow American Jimmy Walker, seeking his first victory on the PGA Tour, was alone in second after matching Wagner for the day's best score, storming home with five birdies in the last nine holes.
Swede Jonas Blixt (67) was a further two strokes back at 10 under, a shot better than Australians Steven Bowditch (69) and Matt Jones (66), and American teenager Jordan Spieth (67).
American Matt Every, the 36-hole leader after opening with scores of 69 and 62, tumbled backwards with four bogeys in the first seven holes on the way to a 74 and a five-under total of 205. (Reporting by Mark Lamport-Stokes in Los Angeles; Editing by Gene Cherry)
