World number one Adam Scott will redouble his efforts in an attempt to add to his one major title after coming up short at the Open Championship for the third successive year.

The Australian, who famously collapsed while holding the lead late on at Lytham in 2012 and was third at Muirfield last year, was in an almost impossible position of being 10 shots behind eventual winner Rory McIlroy heading into the final round.

Scott carded his best round of the week, a 66, to finish 12 under - five behind the champion - to earn a share of fifth place.

The 34-year-old now has nine top-10 finishes in his last 15 major appearances but is keen to turn that into more victories after watching Bubba Watson and Martin Kaymer (both two) and McIlroy (three) all add to their major totals this year.

"I'm motivated now. I'm a little annoyed that I'm leaving here playing well and not winning," said Scott, who broke his major duck with victory at last year's Masters.

"It's down to one major of the year (the US PGA) and it's the last shot at it.

"I'm highly motivated to spend the next two weeks getting in the best possible shape I can to kind of do a Rory or a Martin or Bubba Watson and run away with a major."

McIlroy's third major success, a wire-to-wire victory, means he is the one up there to be shot at now in terms of recent form and Scott, the model of consistency, is looking forward to the challenge.

"It will be fun, yeah, but every week I'm out here I've got to play at a high level just to do that because the level of golf is incredible," he added.

"It's not one guy, it's another guy just tearing up major championships. It's a high standard at the moment."

Scott, who felt he got the worst end of the Thursday-Friday draw, is keen to put another Open disappointment behind him and would love nothing else than to win it at the home of golf in 12 months.

"If you can't win it here then why not win it at St Andrews? That would be an even better story," he said.

In terms of his performance at Hoylake, the Australian admitted he left himself too much to do.

"I was so far behind after 36, it was maybe a little unrealistic to reel Rory in," he said.

"You can get on the wrong side of the draw every now and then but I still feel like I probably could have done a better job of limiting the damage on Friday when it was pretty tough out there (shooting a one-over 73).

"I could have shot a few better than that and then I could have done better yesterday on the front nine (shooting level-par 35) as well.

"It was a slow start when everyone was really going gangbusters.

"Momentum is such a big thing and I had a very stagnant 27 holes in the middle of a tournament. It's tough to recover from.

"I'm going to give myself a little bit of a break and say it was such a lopsided draw this week having only a couple guys in the top-25 after two rounds play on my side of the draw.

"It makes it hard to compete when Rory has obviously played two beautiful rounds."
