Defending champion Lee Westwood carded a four-under 68 for a share of fourth-place after the opening round of the Nedbank Golf Challenge in Sun City.

The 46-year-old former world number one, now ranked 62, is without a title since his three-shot win last year.

He produced a bogey-free round, including one remarkable escape from a buried lie under the lip of a bunker.

Former Open champion Louis Oosthuizen defied illness to lead by three shots at nine under after a bogey-free 63.

South African Oosthuizen, 37, the world number 23, pulled out of the pro-am at the Gary Player Country Club on Wednesday because of problems relating to kidney stones, which required hospital treatment.

"Yesterday I spent a bit of time in the hospital and crawling around my hotel room with kidney stones at 3am this morning, on my knees next to the toilet, which is not a great spot," said Oosthuizen, who holed one of his birdies from 18 feet at the sixth.

"Somehow it got better a lot faster than I expected and it was just one of those rounds where I think everything just fell into place."
