Veteran Australian Peter O&aposMalley is just two shots off the lead going into the final two rounds of the BMW Asian Open. O&aposMalley fired a two-over round of 74 to finish at three-under-par, to trail overnight leaders Robert-Jan Derksen and Zhang Lian-wei by two strokes. Darren Clarke carded a three-under-par 69 at a windy Shanghai Pudong Golf Club and is four-under overall, in outright third place, while Miles Tunnicliff is tied with O&aposMalley at three-under. Joint leader Derksen is also hopeful he can continue his impressive putting into the weekend as he looks to capture only his third victory on the circuit. “I was close to winning twice last year and was a bit unlucky,” he said. “My putting has been good this week and that is key and if I can continue then I should have a chance on Sunday.” Henrik Stenson, the highest-ranked player at the tournament, had started the day just one stroke off the top at four under par but struggled in the windy conditions to drop to level par overall, five shots off the pace. Australian duo Scott Hend and Marcus Fraser are well in contention at one-under, while compatriot Adam Blyth is one stroke further behind in a tie for 16th place. Veteran Australian Greg Norman upstaged many of his younger rivals and is tied with Blyth at level par after shooting an impressive second round of 73 in tricky conditions.
