Ian Poulter birdied six of the first seven holes, but still had four strokes to make up on Rory McIlroy as the US PGA Championship headed towards its climax at Kiawah Island.
After a morning 74 left him with a mountain to climb - he was among 26 players unable to finish the third round on Saturday - Poulter went into overdrive and climbed from joint tenth to second on his own at seven under par.
But he then bogeyed the short eighth and McIlroy regained his grip on the final Major of the season with birdies of his own at the second, third and long seventh.
Four years ago, of course, Poulter finished runner-up to another Irishman - Padraig Harrington - in The Open at Birkdale.
That earned him a Ryder Cup wildcard, whereas this time he was forcing his way into José María Olazábal’s side for Chicago next month.
But it was still McIlroy, last year's US Open Champion, on course for his second Major at the age of 23 years three months - four months younger than Tiger Woods was when he grabbed number two of 14 at the 1999 US PGA.
McIlroy won his first by eight shots, but this one promised the extra satisfaction of beating a chasing Woods.
Not in Washington last June because of injury, Woods was in a tie for fourth with ten holes to go alongside Ireland's Padraig Harrington, who with three successive birdies just before the turn was doing all he could to impress Olazábal.
As he got up and down from sand on the tenth Poulter was joined in second place by Swede Carl Pettersson, who would have been only two back but for a two stroke penalty on the first.
He had driven just into the hazard right of the fairway and television replays showed that he brushed the grass behind the ball in drawing the club back for his second shot.
Pettersson, told about it coming off the fourth tee, showed great character by grabbing birdies at the next two holes and then another on the seventh.
The action began at 7.45am and the completion of the third round certainly did not lack for drama. It even included Woods being attacked by a prickly pear cactus.
"It got in both legs - well, left shoe, right shoe and then in my right leg," he said of the incident right of the 15th fairway.
"It itched like hell for about a hole and then it was gone."
At first Woods, recovering from a "horrific" front nine 40, was limping badly as he made his way down the hole, but he called for a towel from caddie Joe LaCava and carefully extracted the thorns.
McIlroy and Vijay Singh were joint leaders on the resumption and it was a see-saw battle until the latter dropped four shots in four holes and McIlroy birdied the 15th and 16th to go three clear.
He had missed putts of three and five feet before that, however, and before going off for an hour's nap - "I didn't get enough sleep last night" - he spoke about what lay ahead for him.
Reminded that third round leaders have not been faring too well lately - including Scott at The Open last month, of course - he also brought up what happened at Augusta last year.
McIlroy was four clear after 54 holes there and shot 80 before coming back two months later to win the US Open by eight.
"I learned a lot from The Masters and I think it will stand me in great stead this afternoon," he said.
"That's definitely something that I can think back to and draw on some of those memories and some of the feelings I had at Congressional.
"You realise that you might not feel the same or your anxiety level is a little bit higher. At least being in that position before I'll know what to do again."
Poulter continued his brilliant round by pitching to four feet on the long 11th and when he made a nine-footer at the next - it toppled in on its final roll - he was only two behind again.
Pettersson, whose two shot penalty was actually for moving a leaf during his takeaway, was four back at six under starting for home after he and McIlroy both did well to get up and down at the ninth.
Just when Poulter wanted to pile on the pressure he slipped up. A pulled approach to the 13th led to one bogey and missing the green on the short 14th brought another.
McIlroy's pars on ten and 11 - the first of them after a superb recovery from the sand - took him four in front once more, while Poulter was still alone in second as Pettersson had bogeyed the tenth.
Clubhouse leader by then was Justin Rose, round in 66 and unlucky at the short 17th when he carried the lake and then rolled back into it.
He got out of it with a bogey and then had a long wait to see where he ended up.
