Anthony Kim will head into the final round of the US PGA Tour Greenbrier Classic with a one shot lead after firing a blistering third round 62.
The 26 year old Californian picked up eight birdies in his bogey-free round which, after posting 69s in each of his first two rounds, moved him onto ten under overall.
Scott Stallings was hot on his heels a shot back after a blemish-free four under par 66.
Gary Woodland (67) and halfway co-leader Webb Simpson (69) were two shots off the pace, with fellow Americans Jimmy Walker (62), Bill Haas (65) and Chris Couch (67) one stroke further adrift on seven under.
South African Trevor Immelman, the 2008 Masters Tournament champion, was well in contention at the midway point of his round but a double-bogey and four bogeys on his back nine looked to have put paid to his hopes in the tournament.
Simpson was joint leader after two rounds along with Brendon de Jonge, but the Zimbabwean slipped down the field after a nightmare start to his third round.
He double-bogeyed the par four fifth and also dropped shots at the third, seventh and ninth holes before stemming the flow of bogeys to finish with a two over par 72 and a share of 11th spot - five shots off the pace.
England's Brian Davis, who put himself into contention yesterday with a best-of-the-day six under par 64, also made a disappointing start to round three with four bogeys over the first 13 holes but birdies on 17 and 18 helped him recover to level-par 70 and saw him end the day alongside De Jonge on five under.
