Louis Oosthuizen scored a 67 in the fourth and final round at the SA Open
Louis Oosthuizen was crowned tears after winning his first South African Open with a record-equal six shots.
The South African, who won the Open 2010, had an eagle and five birdies in a four-under-67 to win at 18 under.
Matt Wallace of England started the final round in the joint second, three shots drifting from leader Oosthuizen overnight, but sank with a three-against-74.
French Romain Langasque finished second with Oliver Wilson in the shared third.
Wilson ended tie for third in 10 below, after having won 67 cards in the last round.
"I knew it would be very special or heartbreaking today," said Oosthuizen.
"I wish my family was here, the crowd was great this whole week, and it was fun to do it for them."
Oosthuizen, who was forced to return pulling out of the PGA championship in August just before his start time due to back problems, added: "I have been injured, but my family and friends are great."
