Kevin Kisner had a six-under-par 64 on Saturday to build a three-shot lead in the RSM Classic at St. Simons Island, Ga., as he goes for his first win on the PGA Tour.
Already a runner-up four times this year — three in playoffs — Kisner has never had a chance this good.
Kisner made his only bogey of the round on No. 14 and failed to make birdie on the par-five 15th to fall into a tie for the lead with Kevin Chappell. He answered with a key shot that set up birdie, a six-iron into a foot at the par-three 17th and a 30-foot birdie on the 18th to build some separation.
Kisner was at 16-under 196, a record 54-hole score at Sea Island.
