Tiger's substitute, Yang share lead

Graeme McDowell was surprised as anyone to hear the news last week about Tiger Woods in a car accident, having no idea where it would lead - for either of them.

Woods was caught up in allegations of extramarital affairs that made headlines around the world. McDowell was summoned to replace him in the Chevron World Challenge, which could turn into quite the bounty.

McDowell played a six-hole stretch at Sherwood in 6-under par Saturday on his way to a 6-under 66, giving him a share of the lead with Y.E. Yang (71) going into the final round of the $5.75 tournament.

They were at 10-under 206, two shots ahead of Padraig Harrington and European tour money winner Lee Westwood, with Ian Poulter and Jim Furyk another shot behind.

"Obviously, a huge blow for the tournament not to have Tiger here," McDowell said. "I feel very fortunate to receive the invite. It was a great opportunity for me."

McDowell ran off three straight birdies on his back nine, then ripped a 3-wood into 15 feet on the par-5 13th for an eagle, finishing his stretch with a long birdie on the 15th. His only flaw came from a soft lie in the bunker on the par-5 16th, where a fat shot went into the hazard and he took double bogey.

Yang opened with a birdie with hopes of a big day, then stalled until making two birdies on the back nine.

NEDBANK CHALLENGE: Retief Goosen extended his lead at the Nedbank Challenge, shooting a 5-under 67 in the third round to sit two shots clear of Robert Allenby and Angel Cabrera at Sun City, South Africa.

Goosen missed a couple of easy birdie putts but sank a 25-footer from the fringe for an eagle on the ninth. He added three birdies and was at 12-under 204.

Allenby and Cabrera both shot 68.

AUSTRALIAN OPEN: Adam Scott shot a 5-under 67 to take a two-stroke lead into the final round.

Scott had trailed second-round leader Stuart Appleby by two strokes after completing his second round Saturday morning due to a wind suspension Friday. Scott took over the lead within four holes while Appleby (71) trailed for the rest of the day.

Scott had a 15-under 201 on the oceanside links-style New South Wales Golf Club. Australian Nick O'Hern was third following a 71, seven strokes behind Scott.
