Tiger Woods stayed on course for a sixth tournament victory in-a-row by beating South Korea's KJ Choi 3 and 2 in today's quarter-finals at the WGC-Accenture Match Play Championship.

The American world number one, champion at La Costa in 2003 and 2004, chipped in to eagle the par-five 10th before sealing the win with a regulation par on the 16th green.
   
Woods, who needed 20 holes to scrape past Australia's Aaron Baddeley in the previous round, will meet holder Henrik Stenson in the last four, the big-hitting Swede having come from two down after six holes to beat American Woody Austin two up.
   
It was the 10th successive match won at the event by Stenson, who became the second European to win the coveted title with a 2 and 1 victory over Australia's Geoff Ogilvy in last year's final.
   
US Ryder Cup player Stewart Cink never trailed against Argentina's Angel Cabrera before winning 3 and 2 and will meet fellow American Justin Leonard who beat Fiji's Vijay Singh one up.
   
Leonard, who had been three up on Singh after 11 holes, was one ahead with two holes to play and maintained his advantage to the end.
   
Woods lost the par-five opening hole after he pulled his tee shot left into the desert scrub, took a penalty drop and was unable to reach the green with his third. He conceded the hole to Choi, who struck a superb second shot to 10 feet.
   
However, the 13-times major champion immediately recovered when he rolled in a 16-footer to birdie the par-four second and level the match.
   
The next seven holes were halved before Woods chipped in from just short of the green to eagle the 10th and go one up.
   
The world number one doubled his lead by rolling in a 26-foot birdie putt at the 12th and then coaxed in a 23-footer at the par-three 14th to go three up.
   
Choi appeared likely to win the par-four 15th after hitting his approach to four feet but was denied when Woods calmly sank a 31-footer for a matching birdie.
