Louis Oosthuizen has taken charge at the ISPS Handa Perth International in Australia where the South African holds a three-stroke lead following a five-under-par 67 on Saturday.
The world No 21 would have been even further ahead had it not been for back-to-back bogeys at 16 and 17, over the testing Lake Karrinyup layout.
Up until this pair of dropped shots, the 33-year-old had been on a golden run which had seen him cover the previous 22 holes in 12 under par.
He followed a back nine of 31 on Friday, by covering the front nine on Saturday in the same number of strokes.
His nearest challengers going into Sunday's closing round are American Peter Uihlein and Romain Wattel of France.
Going to need to play quite well, because obviously there's a lot of birdies out there, and everyone will be firing.
Uihlein, the joint-leader after 36 holes, could only post a third-day 71 ruined by a back nine of 38 that yielded a triple-bogey at the par-three 12th plus another dropped shot at 18.
Wattel, meanwhile, who is yet to win on the European Tour, carded a joint best-of-day 65.
Oosthuizen was generally happy with his day, although he admitted his disappointment at those two dropped shots: "All in all, there was just two mistakes I made and I played lovely the rest of the round.
"I lost a bit of concentration on 16. I was worrying a bit too much on where the pin position was.
"That probably went over to 17, not doing what I do on the tee shot, working out where the best spot is and just miscued it a little bit and left myself with an awkward little pitch shot.
"So those things happen. As long as it's not happening when you're tied for the lead three holes to go, but luckily there's still a lot of holes left."
Looking ahead to Sunday, he added: "It's a good spot to be in, so looking forward to tomorrow.
"Going to need to play quite well, because obviously there's a lot of birdies out there, and everyone will be firing."
Scotland's David Drysdale leads the British challenge after a 69 which leaves him seven strokes adrift in a tie for 11th.
As for Brett Rumford, who had also been a joint-leader through 36 holes, the Australian slipped five shots off the pace with a 73, despite back-to-back eagles at 14 and 15.
