American Matt Every shot a sensational nine-under-par 61 to lead the field by a shot after the first round of the Wyndham Championship in Greensboro.
The world number 751 finished the day at nine-under par, one shot ahead of Sweden's Henrik Stenson.
The 33-year old Every has two wins on the PGA Tour, the most recent in 2015, but he has missed the cut 20 times this season.
Every started his round in spectacular form, holing from the fairway for an eagle on the first hole at North Carolina’s Sedgefield Country Club. He then added seven more birdies in total for his best ever round in his 11-year career on the PGA Tour.
He also missed a birdie putt on the 18th hole that would have seen him equal the course record.
Every bit of solid.

Every, who has suffered with his driver in recent years, was happy to be back in form.
"The last couple of years have been brutal for me," said Every. "A lot of people probably would have quit so it's good to be back, playing good. I've got a few things to motivate me right now and I want to play well again."
Stenson, the 2016 Open Champion, had four birdies going out and four coming back for a 62.
Six players including Webb Simpson lie a shot behind the Swede on seven under.
