ouis Oosthuizen produced the most electrifying start imaginable to his final round at Augusta on Sunday - holing his approach to the 575-yard second for the first albatross two there in Masters history.
South Africa's 2010 Open champion hit an iron from 260 yards that landed in the middle of the green and - accompanied by an almighty roar that got louder and louder - rolled to the hole and dropped in.
With that one shot Oosthuizen leapt from seven under par to 10 under and, with overnight leader Peter Hanson bogeying the first, he was two in front of both the Swede and three-time champion Phil Mickelson.

Although he had entered the record books it brought back memories of last year when compatriot Charl Schwartzel chipped in at the first and pitched in for eagle on the third to start his charge to the title.
The last player to make an albatross and win the tournament was Gene Sarazen in 1935. His two on the 15th in the second Masters was called "the shot heard round the world" and the only other albatrosses were by Bruce Devlin on the eighth in 1967 and Jeff Maggert on the 13th in 1994.
Oosthuizen did really well to scramble a par on the third after driving right and then sending his approach over the back. And it was a real bonus for him that his lead remained two when Mickelson and Hanson both failed to birdie the second.
Padraig Harrington was the European who made the best start. He birdied the second - it seemed pedestrian by comparison - and was sixth on his own at five under, five behind.
Lee Westwood, also four under overnight, also birdied the second, but it was sandwiched between two bogeys and he was down to eighth on three under with Ian Poulter, while Scot Paul Lawrie bogeyed the short fourth and slipped back to two under.
