Fredrik Jacobson will take a two-shot lead into the final round of the WGC-HSBC Champions event after the Swede held off the challenge of a high-class chasing pack with a third round five-under 67 Saturday. The overnight leader offset a single bogey with six birdies to reach 16-under for the tournament offering $1.2 million to the winner, but will need to maintain his best form on Sunday to stay clear of a host of major winners hot on his heels. Last year's British Open champion Louis Oosthuizen, US Open winners Graeme McDowell and Rory McIlroy and 2010 US PGA champion Martin Kaymer are all within five shots of the lead at the Sheshen International Club. South Africa's Oosthuizen maintained sole possession of second place at 14-under with a 68. Adam Scott moved into third, three shots off the lead. A shot further back from Scott on 12-under are former world number one Lee Westwood (67) and Northern Irishman McIlroy (65). Williams apologizes Caddie Steve Williams has apologized for making a racist remark about former employer Tiger Woods that stunned guests at an awards ceremony in Shanghai. “I apologize for the comments I made last night at the annual Caddie Awards dinner in Shanghai,” Williams said in a statement on his website (www.kiwicaddie.co.nz). Williams had been a regular caddie for Woods since 1999 and helped the American to 13 majors before being fired in July. Three share lead Michael Allen shot a 2-under 69 for a share of the second-round lead with Fred Couples and David Frost Friday in the Champions Tour's season-ending Charles Schwab Championship in San Francisco. Couples, tied for the first-round lead with Jay Haas after a 68, rallied for a 70 after a double bogey on the opening hole. Frost had a 69 to match Couples and Allen at 4 under at TPC Harding Park. Mark Calcavecchia, Jay Don Blake, Bernhard Langer and Kenny Perry were a stroke back. Calcavecchia, Blake and Langer had 68s, and Perry shot a 69. Haas was 2 under after a 72. Charles Schwab Cup points leader Tom Lehman had a 72 to fall four strokes behind the leaders. Allen hasn't won on the tour since the Senior PGA Championship in May 2009.
