Brandt Snedeker predicted low scores at the Wyndham Championship - but not this low.
Snedeker shot an 11-under 59 on Thursday, falling one shot shy of matching the PGA Tour record.
He made a 20-foot putt on his final hole to become the 10th player in tour history to break 60.
It gave him a four-stroke lead after one round.
Ryan Moore and John Oda shot 63s, and Martin Flores, D.A. Points, Brett Stegmaier, David Hearn, Abraham Ancer, Ollie Schniederjans andJonathan Byrd had 64s.
Snedeker, the 2012 FedEx Cup champion, won the Wyndham in 2007.
