Adam Scott says his silky swing was out of sync during his breathtaking first round of the Australian Open at Royal Sydney.

Adam Scott has made the startling confession that he battled swing demons during his breathtaking 10-under-par start to the Australian Open.

In a spectacular opening to his quest to complete Australian golf’s Triple Crown, Scott birdied his first six holes – and last four – to smash the old course record at Royal Sydney by a staggering three shots.

He is three clear of the field and so sublime was the world No.2’s laser-like ball-striking that the longest birdie putt he made was from less than 15 feet.

Scott’s other nine birdies were all accrued from less than six feet and he even thought a magical 59 may have been on the cards.

“It’s an amazing start,” Scott said.

“I remember Greg Norman birdieing the first six holes at Royal Troon in 1989 and that was about as good a start as I can remember.

“Today obviously was very good.”

So good that the Masters champion admitted he toyed with the idea of breaking 60 before cooling off mid-round with eight consecutive pars.

“I wasn’t thinking about it hard but I knew it was a possibility,” Scott said.

“Having birdied the six holes I’d birdied, I felt like all the opportunities were still to come.

“So if I’d kept it going and had a good run around the turn, I felt like it was on for sure.”

Yet, ominously for his pursuers, the perfectionist in Scott also admitted he feared losing control during his eight-hole stretch of pars.

“I can’t sit here and complain about anything but, a bit like last week in the first round, the swing wanders on a couple of shots and it did it again today,” Scott said.

“It’s not quite in the slot. Although I hit a lot of great shots today it’s not as free flowing as the first couple of weeks (of the summer).

“The swing is a bit of hard work for me at the moment.”

In the end, Scott was relieved to post his 62, which demolished the previous course record jointly shared by Chris Gaunt, Matt Goggin, Stephen Dartnall, Ewan Porter and Jason Norris all recorded at the 2008 Australian Open.

“I was really happy to finish the round off with four birdies because I felt like I’d created such a great opportunity to have a really low round out here and didn’t want to waste it,” he said.

Three in front of little-known Canadian Ryan Yip and American John Young Kim and four ahead of countryman David McKenzie, Scott is on track to add the Open title to his victories at the Australian Masters and Australian PGA.

Two-time champion Aaron Baddeley is a further shot back in a four-way share of fifth place after carding a five-under 67, while former world No.1 Rory McIlroy birdied the last for a 69 and will enjoy the much easier morning conditions for his second round on Friday.

Jason Day signed off for a 70 playing alongside Scott, his World Cup-winning teammate from last week.

Day said he was in awe of Scott’s dazzling display.

“You’re just watching the show really,” he said.

“That’s how the best players in the world play and I got to witness it today and it was special.

“That’s something that I’m going to remember for a long time.”
