MARANA, Arizona (Reuters) - Last year's runner-up Paul Casey continued his barnstorming run at the WGC-Accenture Match Play by brushing aside British Open champion Stewart Cink 5 & 4 in Saturday's quarter-finals.

It was the fourth straight 5 & 4 win this week for Casey, who was beaten by Australian Geoff Ogilvy in the 2009 final.

The Briton next plays Colombian Camilo Villegas while Sergio Garcia takes on European Ryder Cup team mate Ian Poulter.

Casey, who never trailed against American Cink, was surprised at the ease of his victory.

"I know how tough Stewart is and I thought this would go all the way," the Englishman told reporters. "I'm very happy to be standing here but still a little shocked.

"Stewart's been very gracious. I made a lot of putts today and I feel sorry for him."

Villegas also shrugged off the chilly and windy morning conditions to beat South African Retief Goosen 4 & 3 while Garcia overcame Briton Oliver Wilson by the same score.

"It wasn't easy out there (and) we didn't play our best, that's for sure," said Spaniard Garcia.

"I managed to do better the last four holes but I need to play better. I'm looking forward to the challenge."

In the only close quarter-final, Briton Poulter edged Thai Thongchai Jaidee by one hole.

Thongchai had a golden opportunity to win the 18th and send the match to sudden-death but his 15-foot birdie putt stopped on the edge of the cup before Poulter sank a seven-footer to secure victory.
