Pakistan Tennis Federation (PTF) has given up hopes of convincing Indian tennis star Sania Mirza to play a exhibition match for flood relief victims in Lahore after she allegedly demanded USD 25,000 dollars to make the appearance. Acting PTF President Irshad Bhatti said that the federation had been very keen to organise a match between Sania and Kveta Peshke, who is the mixed doubles partner of Pakistani tennis star Aisam-ul-Haq.
