Fredrik Jacobson (-14) has been a constant on, or around, the top of the leaderboard throughout the third round of the World Golf Championships-HSBC Champions. He's currently two shots ahead of Louis Oosthuizen, who entered the day one back, but the names behind those two have been undergoing seismic changes. Lee Westwood and Martin Kaymer are each 4 under , 14 and 13 holes into their respective rounds, and find themselves just three back. Also in that group is Paul Casey. The four-way tie at 10 under includes Rory McIlroy and Graeme McDowell. The Northern Irishmen are 5 under and 4 under on the day with a few holes to play. Jhonattan Vegas, a TOUR rookie who won the Bob Hope Classic in January, and Harrison Frazar, who earned his maiden victory earlier this year in Memphis, are the day’s biggest movers. Vegas is finished after a 7-under 65 moved him to 9 under on the week. Frazar has bounced back from a Friday 75 to be 9 under through 16 holes in his third round. Frazar started on the back nine and had seven birdies, one bogey and one par to turn at 6 under. He’s alternated pars and birdies on his first seven holes on the front nine.

Fredrik Jacobson birdied three of the first four holes in Round 3 to move three clear of the pack at Sheshan. This long double-breaker was the second of his early birdies.

Lee Westwood fully understands the long history that has set each of the four major championships apart on golf’s global calendar. Even so,  the world No. 2 thinks there’s room for another.

“I like the tradition of the majors,” Westwood said recently. “I think the men’s game has got it pretty much right, although I’d like to see another major somewhere else in the world. Somewhere like Asia or Australia.”

Westwood, who has won 33 times around the world, has finished third or better in six of the last 12 majors but has yet to pick up his first title. Click here to read more about Westwood's comments .
