Australian Rod Pampling surged into a three-shot lead going into the final round of the Memorial tournament.
Pampling fired a third-round 68 to reach 15 under ahead of countryman Adam Scott (72) and American Sean O'Hair (69) at Muirfield Village, Ohio.
Americans Will MacKenzie (65) and Stewart Cink (65) shared the low round of the day to climb into contention at -11 with Australian Aaron Baddeley.
Tiger Woods is well adrift at four under with Ernie Els and Vijay Singh.
World number one Woods carded a 70 on Saturday, with South Africa's Els shooting 71 and Fijian Singh also taking 71.
The leading European was Swede Frederik Jacobson who had a 68 for 10 under, while Paul Casey was the highest-placed Briton in a tie for 27th at five under alongside the likes of Spain's Sergio Garcia and former Open champion Ben Curtis.
They have to make birdies, whereas if there's a tough pin, I don't have to be as aggressive
Pampling enjoyed a two-shot swing at the last when his nine-iron approach from a fairway bunker set up a birdie as playing partner Scott, the overnight leader, dropped a shot.
"Finishing with four birdies on the back nine really gave me a lot of confidence for tomorrow," said Pampling.
"I guess it's just the luck of the draw. We both hit shots exactly the same off the tee (but) I had a nice flat lie in the bunker and Adam had a pretty gnarly lie (in the rough).
"Thankfully it went my way and I hit a great shot out. Adam couldn't do a lot with what he had.
"If I can get off to a nice start tomorrow, it puts more pressure on those guys, because they have to make birdies, whereas if there's a tough pin, I don't have to be as aggressive."
Scott said: "I didn't really get it going out there today. It's pretty hard to back up a (second round) 62."
Play was delayed for more than two hours because of lightning in the area.
A dubious forecast for Sunday prompted officials to bring forward the tee times in an effort to beat the expected bad weather.
