Colombia's Sebastián Muñoz tied the course record of 60 at the Seaside course on day one of the RSM Classic.
Blistering Muñoz had the putter heated up early on the PGA Tour as the conditions meant several players went low in the fall swing event.
Muñoz made five birdies on the front nine. Three more followed on the back and an eagle to give him a one stroke lead.
The Colombian, 28, is being chased by journeyman and Ryder Cup vice-captain Zach Johnson (61) and three others.
He is looking for his second win on the PGA Tour.

Mackenzie Hughes, Scott Stallings, and Chez Reave find themselves on 9-under.
Canada's Corey Conners (62) made six birdies in a row and faced no putt longer than five feet in that stretch.
In that spell, the longest putt he faced was from four feet and 10 inches in one of the finest birdie streaks we've seen in quite some time.
His fellow countryman Hughes was on 59 watch early after turning in 6-under on the Plantation course.

Two more birdies followed quickly on the back nine but he faded and couldn't keep the hot streak going and carded a 9-under 63.
Hughes was the 2016 champion of this event.
Scottie Scheffler opened with a solid 7-under on the Seaside course after his putter warmed up on the back nine.
Four birdies made from 15 followed after he made the turn in 3-under.
Elsewhere, England's Justin Rose returned to some form when he made four birdies back-to-back on day one at the Plantation course.

The leader board is log-jammed after 18 holes and the weather forecast for round two means they might not have things as easy.
On day one the message was simple on both courses: go get it.
Russell Henley (64) and Jhonnatan Vegas (64) also enjoyed good starts.
Matt Kuchar displayed a new putting grip on day one, presenting no loft on his putter as he rested the grip on his trail arm.
Talor Gooch also has started well again.
Tournament host Davis Lovie III shot 4-under, alongside Luke Donald who also signed for an opening 68.
