Troy Merritt felt the fear Saturday he experienced during his successful amateur career. The third-round leader at the RBC Heritage expects another healthy dose Sunday. Merritt shot a 2-under-par 69 to take a three-stroke lead over defending champion Matt Kuchar, Brendon Todd and Kevin Kisner at Hilton Head Island, S.C. Watson said at the RBC Heritage that it’s getting more difficult for him to compete on the PGA Tour and he didn’t know how much longer he wanted to take away a spot in events from younger players. Olin Browne shot a tournament-record 8-under 64 to take the second-round lead in the Greater Gwinnett Championship in Atlanta, then watched Bernhard Langer match the mark to stay close. Thailand’s Kiradech Aphibarnrat shot a 4-under 68 to take the lead after the third round at the inaugural Shenzhen (China) International, though he let a five-shot advantage slip to two strokes over American Peter Uihlein with a double bogey-bogey on this final two holes.
