Johnson surges ahead at WGC-HSBC Champions

US golfer Dustin Johnson fired a record-equalling nine-under-par 63 to establish a five-shot advantage over the chasing pack after the second round of the WGC-HSBC Champions Friday.

Major winner Bubba Watson and fellow American Boo Weekley shared second place with World No.6 Rory McIlroy of Northern Ireland after the trio returned with matching seven-under-par 137 totals at the Sheshan International Golf Club. Ernie Els of South Africa is among six in tied-fifth on 138.

Starting his round in tied-eighth, four shots back of McIlroy, Johnson got off to a blistering start with six birdies in his first seven holes. After dropping his only shot of the day at the par-four 10th, the Ryder Cup star picked up four shots in his last six holes before signing for a 132 total.

"I'm definitely happy where I'm at. I've played really well the last two days. I've really driven the ball well and for me, that's a big key. I don't intend to play defensively. I just play my game which is pretty aggressive," said Johnson.

Former World No.1 McIlroy, who started on the par-four first, reached the turn in 10-under after a hat-trick of birdies from the sixth hole. However, he struggled to create a single birdie opportunity on his way home and had to return those three shots after bogeys on holes 11, 15 and 18.

"Obviously I played nicely the front nine and then started to hit a lot of sloppy shots on the back. I missed seven greens on the back nine, so there's a bit of work needed on the range," said McIlroy.

China's Liang Wen-chong and Korea's Jin Jeong finished as the highest-placed Asians, carding rounds of 67 and 69, respectively.
