American Kevin Stadler holds a one-stroke lead over a rapidly closing Phil Mickelson as Brett Rumford continues to be the best of the Australian contingent at the HSBC Champions in Shanghai. After posting an eight-under 64 on the opening day, Stadler could only manage a three-under-par 69 on day two, exposing him to world number two Mickelson who closed the gap with birdies on the last three holes for a bogey free 66 at the Sheshan International Golf Club. Asian Tour&aposs Simon Yates of Scotland posted a similar score as he leaped up to tied third position alongside Englishman Ross Fisher (68) while Fijian Vijay Singh posted a 70 and is four strokes off the pace. Rumford, though, is the best of the Australian contingent having carded a one-under 71 in his second round that consisted of five birdies and four bogeys. He is one-stroke ahead of Nathan Green, whose four-under 69 saw him rise significantly on the leaderboard, as Scott Sterling and Scott Hend find themselves at two and one-under respectively on the overall leaderboard. John Senden is further back at one-over as several big names flounder at the Shanghai tournament, with Marc Leishmann and Rod Pampling both at two-over overall. Further back, two rounds of 74 sees Nick O&aposHern at four-over going into the weekend as Paul Sheehan survived the cut by a stroke after carding a three-over 75 on Friday to be five-over overall. However, Richard Green was not so fortunate, slumping to a five-over 78 on day two as he missed the cut on seven-over.
