Brendon de Jonge has tied the course record at Quail Hollow Club with a second round 62 at the Wells Fargo Championship, an 18-shot improvement over his first round 80.
De Jonge missed a 19-foot birdie putt on the final hole Friday that would have broken the course record set by Rory McIlroy in the final round in 2010.
De Jonge shot 80 in the first round.
De Jonge's 18-shot turnaround was the second-largest from one round to the next since Kevin Stadler shot 61-81 in 1980 at Frys.com Open, according the PGA Tour.
The Zimbabwe native says he went out not expecting to make the cut after his poor opening round, but left the course Friday tied for 26th place.
Says de Jonge, "Golf is a strange game."
