Australian Peter O&aposMalley is leading the way at the BMW Asian Open, posting a five-under 67 on the first day to lead the field by a stroke going into round two. O&aposMalley enjoyed a sensational start at the Tomson Golf Course in Shanghai. Starting on the back nine, the New South Welshman fired in four birdies before turning with a bogey on the 18th. However, he couldn&apost sustain that form into his front nine, just managing a further two birdies to finish the day on a respectable 67. O&aposMalley is one stroke ahead of a four-strong group of players on four-under that consists of Mikko Ilonen, Jeev Milkha Singh, Oliver Wilson and Henrik Stenson. Indeed, Stenson was unfortunate not to be level with O&aposMalley at the end of his round, but the Swede bogeyed the 18th and missed his opportunity. One stroke further back is Australian Scott Hend, who endured a topsy turvy round on Thursday. Hend, started confidently from the back nine, producing three birdies and a bogey. His round improved when he posted a birdie and an eagle at the first and second respectively, but the Australian slumped towards the end of his round as he double bogeyed the seventh to drop below the leaders with a three-under 69. Further back, Australian Marcus Fraser is on two-under alongside New Zealand&aposs Richard Lee, with both players ahead of Lee&aposs compatriot in the out-of-form Michael Campbell, who has endured a horror run on the US PGA Tour in recent times. Campbell is alongside Australian Scott Strange on one-under and Aussie sporting legend Greg Norman. Scott Barr managed an even-par 72 to be one stroke ahead of Marcus Both and David Gleeson, while four Australians, Adam Blyth, David Bransdon, Terry Pilkadaris and Kane Webber, are all at two-over, having signed for 74s on their cards.
