Pakistan on Monday called up uncapped players Saim Ayub, Aamir Jamal and Khurrum Shehzad for the three-Test series in Australia, starting in December after fast bowler Naseem Shah couldn't recover from a shoulder surgery for the tour. Shan Masood will be leading the 18-member squad against Australia with new chief selector, Wahab Riaz also recalling left-arm pacer, Mir Hamza for the tour for which nine players from the World Cup squad have also been retained. Pakistan plays three Tests before moving on to New Zealand for five T20 internationals but Wahab only named the Test squad on Monday. While swashbuckling opener, Saim Ayub has played 8 T20 internationals and Aamir Jamal four T20 matches, pace bowler Khurrum Shehzad has been called up for the first time by Pakistani selectors due to his impressive performances in domestic cricket.
