WOODS AND WATNEY SHARE LEAD

First-round leader Nick Watney battled to a two-under 70 to join Woods at 10 under par overall, with Spaniard Alvaro Quiros joining world number two Phil Mickelson and Ryan Moore at the head of the chasing pack.

Former champion Mickelson posted a bogey-free 66, while Qatar Masters champion Quiros dropped just one shot in his 66 and Moore carded a hard-fought 69.

At the top of a congested leaderboard, Volvo World Match Play Championship finalist Anthony Kim (69) claimed sixth at eight under, with Pat Perez (69) a further shot back and Brian Gay (69) at six under with India's Jyoti Randhawa (70).

Woods was just one under through the turn but made his move on the back nine as a brilliant chip-in birdie on the 16th and a fourth gain in eight holes at the last earned the two-time HSBC Champions runner-up a share of the lead.
