Lee Westwood of England has it all to do over the weekend, as he trails Rory McIlroy by six strokes after 36 holes of the Shanghai Masters Golf Tournament in China.

McIlroy of Northern Ireland leads the race for golf's biggest first prize of $2million after the second round of the Lake Malaren Shanghai Masters. 

The 2011 US Open champion, added a 69 to his opening round of 64, to be on 11 under par, 133 and two shots in front of 20-year-old Korean Noh Seung-yul. 

The Irish golfer found a bit of bunker trouble during his second round and was overtaken when he double-bogeyed the ninth hole, but carded birdies at the 11th, 13th, 15th and 18th holes to go into the third round two strokes ahead. 

Korean Noh Seung-yul made the biggest move of the day, firing nine birdies for a 63 - the lowest round of the golf tournament so far - and moving up from tied 18th place to second spot. 

Malaysian Open Champion Noh Seung-yul, ranked 95th in the world, birdied three of his last four holes to finish off the round in style.

Anthony Kim of the United States (68) and 2010 Open Golf Champion Louis Oosthuizen of South Africa (66) were a stroke behind Noh at eight under par, 136, followed by Padraig Harrington of Ireland (70) and Hunter Mahan of the United States (72).

Mahan, who was in second place after the first round, also had problems on the outward nine, bogeying twice and carding just one birdie. 

Ian Poulter (71) and Robert Karlsson (69) are on six under par, 138, and two-time major champion John Daly followed his opening 69 with a 70 to tie Lee Westwood (70), Colin Montgomerie (69) and US Masters champion Charl Schwartzel (69) at five under par, 139.
