ST. SIMONS ISLAND, Ga. — PGA TOUR rookie Austin Cook sank a 6-foot birdie putt on his final hole for an 8-under 62 and a one-shot lead going into the weekend at RSM Classic.

Cook has gone 36 holes without making a bogey on the Plantation Course or the Seaside Course at Sea Island Golf Club. He played Seaside on Friday and ran off four-straight birdies on his opening nine holes.

Cook was at 14-under 128 and had a one-stroke lead over Brian Gay, who shot 64 on Seaside. No one else was closer than five shots going into the final two rounds.

Brandt Snedeker is looking strong in his first start in some five months because of a sternum injury. Snedeker shot a 67 on the Plantation course and is six shots back.
