World Number One Tiger Woods ominously established a one stroke lead at the World Golf Championships-HSBC Champions on Saturday as The Race to Dubai leader Lee Westwood stormed into contention with a sparkling seven under par 65.
Woods, the runner up on his previous two visits to Shanghai, progressed to 12 under par through 13 holes of his second round to top the leaderboard ahead of Ryder Cup team-mates Phil Mickelson and Anthony Kim and another fellow American Nick Watney.
Westwood climbed up the leaderboard to set the clubhouse mark at ten under par after dropping just one shot during his impressive third round.
Woods began the day tied for the lead with Watney after posting a second consecutive six under 66 on Friday and was quickly out of the blocks in pursuit of a 17th individual WGC title with three gains over his opening eight holes.
A missed six foot par putt at nine ruined his perfect front nine at Sheshan International Golf Club and halved his two stroke lead.
Woods was back up and running at the start of the back nine with a fourth birdie of the day, but he handed the shot straight back as the wind began to pick up and limit scoring.
