Argentina's Angel Cabrera clung to a one-stroke lead over Australian Jason Day in the back nine of Sunday's rainy final round at the 77th Masters.
Cabrera, the 2007 US Open and 2009 Masters champion, birdied the par-5 second and par-4 seventh holes but began the back nine with a bogey to stand on eight under through 12 holes in the final round.
Day, trying to become the first Aussie to win the Masters, birdied the par-5 13th to stand on seven under, one stroke ahead of compatriots Adam Scott and Mark Leishman with American Brandt Snedeker on five under.
Denmark's Thorbjorn Olesen took a bogey at 18 but still had the clubhouse lead on four-under par 284 to share sixth overall after a four-under 68 in the final round.
World number one Tiger Woods birdied the 13th to reach four under, matching Spain's Sergio Garcia and Olesen for sixth but four strokes off the pace.
