GREENSBORO, NORTH CAROLINA (REUTERS) - Brandt Snedeker clung to a one-stroke lead over fellow American Brian Gay and Canadian David Hearn after the third round at the Wyndham Championship on Sunday (Aug 19) morning.

Twenty-three players were bunched within six strokes on a packed leaderboard heading into the final round later in the day. Among those in the hunt was out-of-form Spaniard Sergio Garcia, four strokes behind after a 67.

He would have been closer if not for a poor drive at the last which led to a bogey.

Snedeker, among 30 players who completed the round on Sunday following the previous day's weather delay, could only muster two birdies in the final 11 holes. He also made two bogeys and settled for a two-under-par 68 at Sedgefield Country Club.

Snedeker posted a 16-under 194 total.

He is seeking to win wire-to-wire, after shooting a 59 in the first round. Gay jumped within a shot of the lead with a third-round 62, while Hearn carded 64.

The final round was scheduled to start late morning in an effort to conclude the event by 6pm local time (6am Singapore time).
