HILTON HEAD ISLAND, S.C. -- Two-time champion Stewart Cink moved into position for a third RBC Heritage title, shooting a second straight 63 to set the 36-hole scoring mark at Harbour Town.
Cink, 47, appears unstoppable after two amazing days. He sits at 16-under 126, five shots ahead of Corey Conners. The previous best midway score was 129, set by Jack Nicklaus en route to victory in 1975 and matched by Phil Mickelson, who wound up third in 2002.
Conners shot 64 and was 11 under. Emiliano Grillo (64) was another shot behind.
