Louis Oosthuizen (pictured) holed a 35-foot birdie putt on on the 17th hole to shake off the challenge of fellow South African Tjaart van der Walt and retain his title at the Africa Open on Sunday.

Oosthuizen beat Van der Walt by two shots.

Retief Goosen, who won the Africa Open in 2009, finished third.

"The 17th was playing really tough today with the wind blowing off the right," Oosthuizen said.

"When Tjaart hit it short I aimed for the middle of the green. I had been leaving my putts short all day but I hit it firmly and it rolled really nicely."
