LAHORE - Pakistan crashed to their heaviest defeat at home ground - by 234 runs - against Sri Lanka to lose the three-match ODI series 2-1 here at the Gaddafi Stadium on Saturday, with thanks to nearly run-a-ball century by Tilkaratne Dilshan. Chasing an impregnable total in the presence of two world-class spinners Muttiah Muralitharan, who also reached 500 wickets in ODIs and Delip Mendis, Pakistan capitulated at 75 in 22.5 overs at the hands of the tourists attack of Thushara Mirando and Nuwan Kulasekara. Pakistan were in disarray right from the start with the fall of four key wickets by the seventh over. As they entered into bat for their chase, to the surprise of all, Pakistan's in-form batsman Salman Butt came down the order due to technical reasons and Younus Khan came for opening with Khurram Manzoor. Pakistan woes began in the second over when the LBW of Younus by Mirando send jitters in Pakistan camps and then Kulasekera doubled the trouble by Salman Butt's wicket for a duck. Khurram and Kamran Akmal were looked at to keep the patience and runs going, but the latter was trapped LBW by Mirando and the opener followed suit with a stunning catch at shot square leg by Maharoof off Kulasekara. When the hopes rested with Shoaib Malik and Misbahul Haq, they did not show any responsibility and Shahid Afridi join Malik after Misbah got out. Mirando took his third wicket by skidding the ball to edge out to Sangakkara behind the stumps. And Afridi was bowled for leaving an incomer of Kulasekara. Following that , Malik (19), Umer Gul (27), Rao Iftikhar, Saeed Ajmal and Sohail Khan played their part in the innings. Although defeat was imminent, Malik and Gul entertained the crowd with some good hitting. Dilip Mandis, Maharoof and Muralitharan shared the remaining wickets with Murali joining the 500 wickets club with his two wickets. Century-maker Dilshan batted through the innings after the fall of his opening partner. He not only maintained the flow of runs but powered the total to 309. Before he, completed the second wicket 50 off 55 balls with Kumar Sangakkara, Sri Lanka was well in control of the game. He then went on to develop 100 runs partnership with Sangakkara, who was later run out by Shahid Afridi for 50 off 58 balls. Dilshan built his hundred steadily while his partner Thilana Kandamby lofted a ball and Khurrum Manzoor caught it at deep square leg boundary. Sri Lanka reached 100 runs in 18.2 overs as their first 50 came in the 13th over which speaks of the opening attack line and length and the second 50 came when Rao Iftikhar was put to sword first by Jayasuriya and then by Dilshan. The tourists' top order thus laid a solid foundation, which the middle order with the brilliance of Dilshan managed to reach 250 by the 44th over. By then Pakistan not only lost the grip on the match, but also Saeed Ajmal to injury in an attempt to save a boundary at deep square leg off Sohail. Gul gave Pakistan a little hope of keeping the tourists under 300 runs by taking two wickets in the 48th over and his eighth. But the last two overs produced 17 runs giving Pakistan a target of 310 to achieve. The next coming player after Kandamby, Sri Lankan captain Mahela Jayawardene, got three balls off the rope before losing his wicket to Gul with Kamran Akmal doing the rest diving to his right and two balls later Akmal again took a catch of Chamara Kapugedera. Earlier, Jayasuriya paced the runs rate with his aggressive batting once the Sri Lanka total crossed 50 in the 13th over. He smashed Rao Iftikhar for 25 runs in the 15th over hitting a six and three fours including a four off wide ball. But the very next ball of Gul, which was his first of the second spell, made him mistime a slower delivery to mid-on to Saeed Ajmal. Jayasuriya managed 45 of 48 balls with a six and five boundaries until then Umer Gul and Sohail Khan kept them in check. With the fall of Jayasuria wicket the opening wicket partnership of 76 runs also ended in 15.1 overs. Losing the toss of the day, Pakistan fielders also dropped both the openers. When total was at eight, Salman Butt dropped it off a ball from Gul at the covers coming from the bat of Dilshan and later in the 6th over Younus leaned to his right full stretch in an in vain attempt to hold Jayasuriya. However, despite tight line from Gul and Sohail, both these openers flourished after the 10th over. Pakistan entered the field with two changes bringing in Sohail Khan and Saeed Ajmal in place of out of sorts Shoaib Akhtar and Sohail Tanvir while the tourists made not change in the winning combination that won the second ODI.
