Dustin Johnson delivers the goods on day two at the HSBC Champions event on day two in Shanghai. Dustin Johnson / Getty Images Dustin equalled the course record at Sheshan International Golf Course, shooting a second round -9 under par 63, for a tournament total of -12 under par. That equates to a five shot lead after just two rounds of golf. Dustin modestly admitted he played very well; "Yesterday, I didn't start off so good but I played well after that. I hit it really good out of the gates today and obviously I putted really well." Yesterdays first round leader Rory McIlroy had a rather quiet round today, an even par round of 72, leaving him tied in second place at -7 under par. Sharing that spot with him are Bubba Watson and Boo Weekley, Bubba with his -3 under par second round and Boo with a -5 under effort. Rory said he was disappointed; "Disappointing, frustrating, obviously played nicely the front nine and then started to hit a lot of sloppy shots on the back. Missed the last six greens in a row. Missed seven greens on the back nine, so a bit of work needed on the range this afternoon. It would have been nice to play a bit better and start tomorrow with a few more shots in hand but I guess I'm in a decent position going into the weekend, and still have a great chance at winning this tournament," Bubba made a mistake today, but finished strongly; " I made a double on No. 10, a quick double after being in the middle of the fairway, but then I made some good putts, some good quality shots, and finished up strong. We've still got two more days, two more days, a lot could happen. I could be dead last by the end of the week. Right now I'm just taking it in my stride and hopefully come out and make some putts and hit the ball just as could." There are six players tied in fifth place at -6 under par, six shots off the lead and must be thinking the title is already destined to go elsewhere. Tommy Fleetwood, Sergio Garcia, Gonzo Fdez-Castano, Ernie Els, Graeme McDowell and Ian Poulter are going to be fighting for the minor placings, unless Dustin somehow implodes.
