The big-hitting Argentine started with a two-shot lead but slid to seven under with South African Tim Clark and Australia's Adam Scott.

Clark outshone his big-name rivals to move into contention with a superb 67 on Saturday. Scott posted a 68.

Scott said: "We're bunched up and it's anybody's title now."

American Jim Furyk and South African Retief Goosen are a shot further back.

Britain's Darren Clarke and Luke Donald are tied on three under.

"I actually only hit two bad shots but they cost me five strokes Angel Cabrera

Cabrera, who set the course record on Friday with a 64 to leap to nine under, began with a bogey and birdie before a disastrous eighth hole cost him two shots.

Having missed the green at the par four he misjudged his chip, duffed his next effort a matter of inches, nearly holed his fifth and finally tapped in for a double-bogey.

But, after four more birdies and another bogey, Cabrera still looked on course to retain a solo three-stroke lead until a nightmare 17th hole, which cost him his advantage.

He said: "I actually only hit two bad shots but they cost me five strokes.

"Fortunately, I still have a share of the lead and I just have to go out on Sunday and put those two bad holes today out of my mind. A good final round and I can still."

Thick grass

Clark enjoyed better fortunes as he carded six birdies and one bogey to move from two-under into a share of the lead.

He had six birdies after 12 but found the thick grass in the bunker in front of the 14th green and after hacking out could not get up and down.

Clark said: "The harder the wind blows, the better it is for me.

"I grew up playing in the wind, and it brings out the best in me."

Northern Ireland's Clarke began the day two strokes behind Cabrera but had a disastrous start with double bogeys at the par-four third and the fourth, where he hit his tee shot into the water.

He pulled stroke back at the par-five ninth but then dropped it again at the 13th to leave him on three under, tied for fifth with fellow Ryder Cup star Donald, who carded 75.

Scott, who had the only eagle of the tournament so far, said: "It wasn't easy out there because the wind was swirling and you were never sure where it was coming from."
