Australian Jason Day birdied the par-5 13th and par-4 14th holes to seize the lead of the 77th Masters in Sunday's rainy final round after Angel Cabrera made a bogey at the 13th.
Day stood on eight under with four holes remaining, one stroke ahead of Cabrera, who put his approach at the 13th into Rae's Creek, and Aussie Adam Scott, who birdied the 13th and was on seven under with four holes to play.
Aussie Marc Leishman was fourth on six under with four to play.
The Australians are all trying to become the first player from their homeland to win the Masters, ending a jinx legacy best known for Greg Norman's three heart-wrenching runner-up finishes at Augusta Nation.
World number one Tiger Woods birdied the par-5 15th to reach five under, only three off the lead but with only three holes to play and with the leaders yet to reach the 15th.
Brandt Snedeker was also on five under.
Denmark's Thorbjorn Olesen had the clubhouse lead on four-under par 284 to stand seventh overall after a four-under 68 in the final round.
Spain's Sergio Garcia was in on 285.
