Geoff Ogilvy will carry a two-stroke lead heading into Sunday's final round of the Australian Open, but he has a raft of big names including American superstar Jordan Spieth on his tail.
Ogilvy expressed surprise after firing the low round of the tournament, a brilliant, unblemished eight-under-par 64 at Royal Sydney on Saturday.
The former US Open champion is 11-under, with Spieth lurking ominously two shots back after grinding out a third-round 68 despite a shaky start.
Two-time champion Aaron Baddeley is also at nine-under after carding a 67, as is Ryan Fox (70) in his bid to become the first New Zealander in more than a century to lift the Stonehaven Cup.
In-form veteran Rod Pampling is three off the pace after a rollercoaster round of 70 vaulted the 47-year-old into contention for his maiden national championship.
Adam Scott is a further shot back at seven under after salvaging a 71 with two late birdies.
Ogilvy made the most of the favourable early morning conditions to go out in a red-hot six-under 30 courtesy of birdies at the first, second, sixth, seventh, eighth and ninth holes.
He didn't grab another birdie until the par-five 16th, where he moved into the outright lead.
The 2010 Open champion iced his round with a stunning approach on the 18th for a tap-in birdie three.
"To be honest, I didn't really see 64 on the first tee," Ogilvy said.
"But after going out so well on the front nine I kind of started seeing a score like that. It's always a nice feeling. I'm back in the mix."
This morning's big mover was unheralded Australian Jake Higginbottom who capitalised on an early tee time, shooting six-under-par 66 to be six-under for the tournament.
The 23-year-old from Charlestown opened his account with a birdie on the first hole, before mixing five birdies and an eagle with two bogeys to sign for a 66.
"It was actually pretty breezy this morning," said Higginbottom, who won the 2012 New Zealand Open as an amateur.
"I played well. They call it moving day for a reason and it's always nice being in contention."
Nitties (74), along with Higginbottom (66), Jason Scrivener (69) and 20-year-old Lucas Herbert (71) all share sixth place with Scott.
Two-time former champion Robert Allenby (68), teenage amateur Min Woo Lee (71) and fellow young gun Cameron Smith (68) are not out of it at six under and five in arrears of Ogilvy.
