SHANGHAI (AFP) Tiger Woods stormed into a share of the lead with Nick Watney at the WGC-HSBC Champions on Friday, as Phil Mickelson charged up the leaderboard to be one shot behind. The world number one birdied the last for a round of 67 to be 10-under-par for the tournament on 134, alongside fellow American Watney who added a 70 to his opening 64. Mickelson, who won here in 2007, was on fire, stroking a majestic bogey-free 66 for a share of second place with Spains Alvaro Quiros (66) and another American Ryan Moore (69). Anthony Kim was a shot further back, ahead of US PGA Tour player Pat Perez on six under. Two-time runner-up Woods survived finding trouble off the first tee to birdie his opening hole but then missed decent chances to pick up more shots before a bogey on the par-3 sixth. But he drilled another birdie on the ninth and when he sunk a 12 footer on the 13th, he was closing on Watney. Woods then produced a piece of magic at the 15th when he chipped in from a steep angle in the rough for a birdie and capped his day with a tap in to pick up another shot on the last. He was frustrated at missing so many early chances but pleased with the way he finished. Well, it was certainly a little bit frustrating. So I knew that if I could just basically play the back nine at three-under par, which would be three-under for the day, I figured that would be a good number, he said. And I did a couple better than that. He added that the pin placements were tough, but opportunities for a low score were there. I was surprised at how difficult the pins were. Consequently, the guys didnt go as low, but still there were plenty of opportunities out there. First round leader Watney struggled with his short game, but birdies on the final two holes kept him in the hunt. I played very well again, the main difference today was my putter, said Watney, who won the Buick Invitational this year to qualify for Shanghai, a World Golf Championship event pitting winners from the worlds PGA Tours. Today I struggled with my putting and to finish with two birdies was a bonus. Asked how he would deal with Woods and Mickelson, he said he would just focus on making birdies. I knew from the start that Tiger and Phil were in the field and its no surprise to see them playing well. I need to go out and keep making birdies to have a shot at winning. Mickelson said on Thursday he needed a round in the mid-60s to get himself into contention and he delivered just that, sinking six birdies to position himself perfectly for the weekend. Im pleased with where I put myself after two rounds, said the world number two. Theres a lot of guys up there and Ill need to play very well on the weekend, But Im in a good position. I like this tournament a lot and I like this golf course a lot. Taiwans Lin Wen-Tang set the early pace, picking up five shots in his opening nine holes for the outright lead before a bogey on the 10th and a double bogey at the next saw him drop down the leaderboard. Lin, who defends his Hong Kong Open title next week, ended at five-under for the tournament. Ernie Els improved his chance of making an impact with a hole in one at the sixth after judging an 198 yard six iron to perfection. The South African, who is looking for his first win of the year, followed it up with four birdies before dropping three shots to leave him seven off the pace. Spains Sergio Garcia hit a 70 to go with his first round 75 to be 11 behind Watney, leaving him with no hope of successfully defending his title. Randhawa keeps Asian hopes alive Indias Jyoti Randhawa fired a second round 70 to be four off the lead and head the Asian Tour challenge at the WGC-HSBC Champions on Friday, saying the best putter would win the tournament. Randhawa trails joint leaders Tiger Woods and Nick Watney with Taiwans Lin Wen-Tang a shot behind him, alongside teenage Japanese superstar Ryo Ishikawa. Thailands Thongchai Jaidee, who played with Woods, remains in the hunt after a 69 left him six shots off the pace. Other Asians didnt fare as well, with Koreas Major winner Yang Yong-Eun, the 2006 champion, nine behind the leaders, while Indias Jeev Milkha Singh fired a 72 to go with his opening 73 and leave him 11 shots adrift. Randhawa though is in with a chance and said that with the greens hard and the pin placements tough, whoever was running hot with the putter would win. Im well focused and whenever I got the chance I took advantage of that and that was a good point today, he said. Getting into a good position in two days, it does help you focus better. Asked what he needed to do over the weekend to stay in touch with Woods, he said improving his short game was key. The greens are tricky but guys are holing putts. Its a putting contest now. Whoever makes a lot of putts is going to win because the greens are very tricky. At one point Lin led the tournament at 10-under-par, picking up five shots in his opening nine holes, but a bogey on the 10th and a double bogey at the next saw him drop down the leaderboard. The Taiwan star, who defends his Hong Kong Open title next week, ended at five-under for the tournament and said he made the mistake of thinking too far ahead. Yeah, because I knew there was only me on 10-under, so I said to my caddie, maybe we have a chance but my caddie told me youre too fast, too quick, he said. Then I found trouble. Thongchai said the trick over the weekend was to be patient. Game plan is very important here, he said. Im just going to try the same thing, be patient. Im trying my best. Among other Asian Tour players here, Thailands Prayed Marksaeng improved on his dismal opening round 81 with a 69 but remains tied for 70th. Countryman Chapchai Nirat and Singapores Lam Chih-Bing are both one over for the tournament, while Chinese number one Liang Wenchong struggled to a second consecutive 73 to be a shot further back.
