Adam Scott insists he is not out of US Open contention despite needing to produce the greatest final-round comeback in the event's history after he fell further adrift of 54-hole leader Gary Woodland.
Scott produced a ball-striking clinic on the back nine on Saturday but a series of cruel bounces compounded several missed short putts, as he finished eight shots behind Woodland after the third round.
Queenslander Scott's lacklustre round of even-par 71 left him at three-under, while Woodland shot 69 to move to 11 under.
Woodland will take a one-shot lead into Sunday over former US Open winner Justin Rose (68).
Former world No.1 Scot would need to break Arnold Palmer's record seven-shot comeback, which he set in the final round at the 1960 US Open, to claim his second major title.
He would likely also need to break the record for lowest final round by a winner at any major, which Johnny Miller earned with a 63 when he won the 1973 US Open.
But Scott believes the efficiency with which he is swinging the golf club makes it a slim possibility if he can tidy up his putting.
"Today was by far the most under control I've had the golf swing and the ball in a while," he said.
"If I can swing it like that tomorrow, I feel like there's something mid to low 60s for me.
"It's like Johnny Miller shot that 63 to win ... these things can happen if you play great and get the right breaks for one day
"You see guys breaking major records all the time and I feel it's possible around (Pebble Beach).
"Branden Grace shot 62 (at the 2017 British Open); that had never happened before and Brooks (Koepka) broke records at the PGA for a couple of days."
But the powerful, accurate Woodland - who also played college basketball - was defiant he was going to seal his first major victory on Sunday.
"I've worked for this my whole life; I've trained since I started walking," he said.
"I've competed and learned how to win, even if I haven't done it as much as I'd like.
"I came here to win and that's what we're going out to do tomorrow."
Two-time defending US Open champion Brooks Koepka (68), who won last month's US PGA Championship, lurks ominously in a share of third at seven under with Chez Reavie (68) and Louis Oosthuizen (70).
Scott finished as the leading Australian, with countrymen Jason Day and Marc Leishman each shooting rounds of 70 to finish at even par.
Cameron Smith struggled to a 77 to plummet to seven over.
