Brandt Snedeker shot 11-under-par 59 in the first round at the Wyndham Championship on Thursday, before vowing to keep attacking at an event with a recent history of very low winning scores.
His course record earned a four-stroke lead over fellow Americans Ryan Moore and John Oda at Sedgefield Country Club, which is at the mercy of the field after a wet summer left it soft and defenceless.
Snedeker (2007) and Moore (2009) both claimed their first PGA Tour victory at the Wyndham.
