Queenslander Jake McLeod has set a course record, firing a 10-under-par 62 to go to 19 under and four shots ahead of the field at the NSW Open in Sydney after three rounds.
Starting the day tied 5th, McLeod stepped onto Twin Peaks Golf and Country Club in Luddenham on Saturday feeling unusually relaxed and proceeded to reel off six birdies in seven holes.
"I get very nervous on the first tee no matter what tournament it is or where I'm sitting," he said.
"But I was really calm and I think that birdie on the first really got me going."
McLeod continued the frenzy on the back nine, adding another four-consecutive birdies from the 12th to 15th holes.
The 24-year-old watched an 11th birdie putt disappear into the hole on 17, before tensing up on the 18th and finishing with a three-putt bogey to close the day a stroke better than the previous course record.
"It was pretty surreal," he said.
"I think I just holed everything; I don't know how it happened. Everything just seemed to want to go in."
McLeod is trying to secure his first victory on the PGA Tour of Australasia.
"I think I'm due, past due," he said of his three top-10 finishes on tour this season.
McLeod's third-round playing partner and fellow Queenslander Blake Proverbs also moved his way up the leaderboard.
He fired a five-under 67 to be outright second and trailing McLeod by four.
Proverbs entered the NSW Open after recording a top-10 result at last week's Queensland Open. He needs the same result to qualify for next week's Australian Open.
Overnight leader Harrison Endycott had an adventurous day, making an eagle, five birdies, a bogey and two double bogeys to finish on two-under 70, outright third and five shots off the lead.
At 13-under after 54 holes is Cameron John while rounding out the top five a shot further back is Jordan Mullaney.
