THOUSAND OAKS, California: Tiger Woods carded a six-under par 66 without a bogey Friday to stretch his lead atop the World Challenge tournament to four shots over US Open champion Graeme McDowell. Woods, the 14-time major champion and former world No. 1 who hasn't won a tournament since the 2009 Australian Masters, had a 36-hole total of 13-under 131. This unofficial 18-player event, which Woods hosts for the benefit of his charitable foundation, is the US superstar's last chance to snag a victory in 2010, a year that started amid scandal and saw his struggles on the course mirror his personal travails. Until this week, Woods' only appearance atop a leaderboard this year was a share of first place after the first round of The Barclays. Woods, however, said he felt right at home there. “It feels good,” he said. “I've been here before, so it's not a strange feeling. It's just one of those things where tomorrow is the same game plan, just go out there and plot my way along and take care of the par-fives.” Woods kickstarted his round with an eagle at the 531-yard, par-five second hole, where he stuck his approach from the edge of the fairway within 10 feet. In two days, Woods has played the 10 par-fives at Sherwood Country Club in 10-under. McDowell carded a 69 for 135, while Rory McIlroy, like McDowell from Northern Ireland, took double-bogey at the final hole and settled for a 70 that put him on 136, alongside England's Luke Donald (66). McDowell said he was pleased to squeeze as much as he did out of his round, his eight birdies countering three bogeys and a double-bogey six at the ninth. “Not my best ball-striking round today,” McDowell said. “Played great yesterday, had it on a string, and today I wasn't quite sure where it was going to go. But hung tough ... to shoot three-under and not play my best, I'm pretty happy with that.” Yang seizes lead In Florida, South Korean Amy Yang shot a two-under par 70 Friday to seize a three-stroke lead when play was suspended due to darkness in the second round of the 1.5 million-dollar LPGA Tour Championship. Yang stood on seven-under par 137 after 36 holes at the season-ending event with compatriot Seon Hwa Lee and Sweden's Maria Hjorth sharing second on 140. Lee, who shared the 18-hole lead with Yang, fired a 73. Hjorth had a 68 Friday. Paraguay's Julieta Granada was fourth on 141 with Australian Katherine Hull and Americans Cristie Kerr and Morgan Pressel another stroke off the pace. There were 38 players remaining on the course at Grand Cypress Golf Club when play was suspended, delaying a cut to the low 70 and ties until Saturday morning. No one had more than five holes remaining to complete. The only player not to finish with a strong chance to push her way near the top of the leaderboard was Korean Kyoeng Bae, who stood on two-under, level with the fifth-place pack with four holes remaining in her second round.
