SHANGHAI (AP) - Fredrik Jacobson played bogey-free to shoot a 6-under 66 on Friday and take a one-stroke lead on the soft Sheshan International course at the HSBC Champions.

Jacobson was at 11-under 133, one shot clear of Louis Oosthuizen and Adam Scott, with PGA champion Keegan Bradley another shot behind. Oosthuizen had a tournament-best 63, while Scott had nine birdies in his round of 65.

Sixteen players were separated by five shots going into the weekend, a group that includes Paul Casey, who lost his PGA Tour card this year. A win would give Casey a three-year exemption.
