LAHORE Pakistan have called up the tallest fast bowler in the world when they added Muhammad Irfan to a squad hit by injury and suspension. Irfan replaced suspended bowlers Muhammad Amer and Muhammad Asif for the one-day series. There is a confusion over Irfans exact height but he is thought to be 7ft 1inch, which, if true, makes him the tallest bowler to have played international cricket. The 28-year-old left-arm was lost to cricket when he had to give up the sport to work in a plastic pipe factory to support his family. But collections by Pakistani cricket supporters allowed him to resume his career and after the recommendation from Wasim Akram, he was promoted from Pakistan A team tour to Sri Lanka to join the squad for the Natwest Series against England which begins in Durham on Friday. Irfan has played only 10 first-class matches but his reputation in Pakistan has earned him a contract with the Kolkata Knight Riders in the Indian Premier League next year. Pakistan also called up batsman Asad Shafiq as they moved West from Taunton to Cardiff for todays first Twenty20 international against England where the team will attempt to concentrate on cricket again.
