Pakistan captain Mohammad Hafeez said he is confident his team will beat Australia in the Twenty20 series and go on to prosper at the World Twenty20 championship in Sri Lanka. Pakistan trounced Australia by seven wickets in the first Twenty20 international on Wednesday, taking a 1-0 lead in the three-match series. “Our win will help us in the World Twenty20, we need to carry the winning momentum on into the World Twenty20,” said Hafeez of the World Twenty20 which starts on September 18. Pakistan’s spin trio of Saeed Ajmal, Hasan Raza and Hafeez shared six wickets to bowl Australia out for their second lowest Twenty20 total of 89 before the modest target was achieved for the loss of three wickets. The second match will be played here on Friday. Hafeez denied he was surprised at Australia’s capitulation. “It wasn’t surprising because I am confident that my bowling will come good and this is a good sign for our team ahead of the big event where we want to do well,” said Hafeez.
