Australia’s Adam Scott says he’ll be hard to stop from clinching a second straight Australian Masters title on Sunday if he can maintain his current form.

In-form world No.2 Adam Scott is confident he doesn’t need to change a thing to clinch back-to-back Australian Masters titles at Royal Melbourne on Sunday.

But former world No.1 Vijay Singh doesn’t plan on letting the US Masters champion cruise to victory, despite his four-shot advantage.

Scott, fresh from last week’s Australian PGA win on the Gold Coast, continued his near-faultless form on Saturday, firing a second straight five-under-par 66 to back his opening round 67 and take himself to 14 under par.

But Singh, who started Saturday seven shots off the pace, shot 63, the round of the tournament so far, to climb to 10 under and a share of second place.

The 50-year-old three-time major winner hasn’t won a tournament in five years.

But after a runner-up finish in the Open on the US PGA Tour last month, Singh is relishing the chance to play with Scott in the final group on Sunday.

“It’s a good feeling, it gets your blood flowing again,” Singh said.

All aspects of his game worked well on Saturday and the veteran said warmer weather helped, after a cold start to the tournament.

“I play better when it’s warm so hopefully tomorrow it’s going to be a warm day and I can do what I did today,” Singh said.

Scott, who threw in consecutive three-putt bogeys on the 11th and 12th holes – the only blots on an otherwise exemplary round, said the way he was striking the ball he was capable of a lower score.

But he doesn’t feel any need to change his approach.

“Just keep hitting good quality shots and giving myself opportunities,” Scott said.

“I’m giving myself opportunities every round.

“If I do that I’m going to make a few of them.

“If I make a few of them it will be hard for the others to have enough (to catch up).”

Scott took a gentle dig at Singh’s veteran status ahead of Sunday’s match-up.

“I don’t think we’ve played this year. I don’t see him so much any more now he’s a senior tour player,” Scott said with a smile.

Singh played one senior tour event in September, but has stressed he has no short-term plans to join the over-50s circuit fulltime.

Sharing second place are Australians Nick Cullen, Matthew Griffin and Nathan Holman, with American world No.8 Matt Kuchar a further shot back.
