KARACHI (PPI) Pakistani qualifier Farhan Mehboob resumed his winning spree while top Pakistani squash player Aamir Atlas Khan lost in the quarterfinals of CIMB Malaysian Open at the Curve Shopping Mall in the Kuala Lumpur. The 21-year-old, Farhan Mehboob from Peshawar followed his major first round upset over second-seeded Australian Cameron Pilley by beating Germanys Simon Rosner, the No 8 seed, 11-9, 11-6, 3-11, 11-7 to reach the semi-finals for the first time. In semi-finals, he will now face two-times champion Mohammad Azlan Iskandar of Malaysia. Fourth seed Azlan dispatched another sixth seeded Pakistani player Aamir Atlas Khan by 11-7, 11-8, 11-2 score. There was further Australian disappointment in the top half of the draw when 2007 runner-up Stewart Boswell failed to make the last four.

Momen will now face fellow countryman Mohamed El Shorbagy after the top seed from Alexandria - in his maiden appearance in the event - disappointed the local crowd by defeating Malaysian star Ong Beng Hee, the fifth seed who won the title in 2000, 2005 and 2008, 7-11, 11-8, 11-9, 12-10 after an 81-minute marathon.
