Adam Scott became the first Australian to win the Masters following victory after a sudden-death play-off against Angel Cabrera at Augusta.

Scott avenged his collapse at last year's Open Championship to claim his first major after going into day four two shots behind overnight leaders Brandt Snedeker and Cabrera.

Both players were eight-under heading down the 18th, Scott holing a 15ft putt to go nine-under, only to see Cabrera go within three feet with a superb second shot to set up a play-off.

The pair produced delightful chips to part the first play-off hole at the 18th, but after Cabrera, winner in a play-off in 2009, came up short at the 10th from 12ft, Scott made no mistake to end Australia's 77-year wait for the green jacket.

"I don't know how that happened," Scott said.

"There was some luck there somewhere. It was incredible. It's incredible to be in this position. Australia's a proud sporting nation and it's amazing that it's come down to me today.

"There was one guy who inspired a nation of golfers and that's Greg Norman. Part of this definitely belongs to him."

Fellow-countryman Jason Day finished two shots behind in third despite leading briefly by two with three holes to play, while Tiger Woods and Marc Leishman ended on five-under.

Snedeker, co-leader after day three finished level with Norweijan Thorbjorn Olesen on his Masters debut but the wait for a major championship continues for Sergio Garcia and Lee Westwood, who finished six shots off the pace.

But after the controversies of days two and three, which included controvercial shot penalties first for 14-year old Tianlang Guan for slow play and then for Woods after carding an incorrect scorecard, much integrity in the sport has been re-established after an riveting finale on Sunday.

With the light fading, Scott appeared to have claimed the title on the 18th after he holed superbly to pull one-shot clear, but Cabrera's memorable approach delivered a play-off.

Scott had missed a chip to win the Masters in the first play-off hole but made no mistake when handed a second opportunity to avenge his second place finish at The Open last year, during which he fell away when four shots clear with four holes to play, and at Augusta in 2011.

The 33 year old's victory is particularly poignant having become the first player from down-under to claim the Masters, following Norman's three second place finishes; doing it with a long-handled putter which is set to be outlawed by the sports' governing body.
