KARACHI - Pakistan captain Younis Khan led Pakistan fight back with an unbeaten 149 to keep the Sri Lnakan attack at bay on the third day of the first test here Monday at the National Stadium. He single-handedly fought a grim battle for survival of his team against heavy odds leading Pakistan first time as full captain. Pakistan ended the third days play at 296 for three wickets still far away from the mammoth Sri Lankan total of 644 for seven declared in the first innings. At the close of play along with his captain is dependable Misbahul Haq 20 made in 68 balls. With full two days remaining and still trailing by 348 runs, Pakistan is facing a difficult task to save the test, first of two that the visitors will play in their second part of the tour. Younis's batting and his 149 runs third wicket partnership with his former skipper Shoaib Malik whose innings of 56 came to an unexpected end when he committed hara-kiri by running himself out. Had they stayed together Pakistan would have saved from the much expected follow on. Younis who was unbeaten naught at the close of second days play with the home team at 44 for one and Malik who arrived an hour before lunch time with the fall of second wicket of test debutant opener Khurram Manzoor for 27, raised home hopes high as they added runs batting with responsibility. The two came together when Pakistan lost its second wicket at 78 runs and remained together till the score reached 227, when Malik batting sedately without taking risk suddenly ran for a unnecessary sharp single hitting Ajantha Medis towards mid on. Muralitharan fielding at the spot neatly picked up the ball and with a sharp low throw hit the wickets directly at the bowlers end finding Malik nearly yard short of the crease. Malik got his 56 in 168 ball hitting seven fours. The day, however, belonged to Younis who in his innings gave a chance at 92 with team total at 198 for two wickets. He played a perfect but uppish drive of Dilshan. Ajantha Mendis at short mid wicket failed to grab the opportunity. With a single off Dilhara Fernando, Younis reached 16th century of test career and fourth against Sri Lanka. It was against Sri Lanka he had scored his first test century at Rawalpindi eight years ago. Misbah who came at the critical juncture of the match also showed responsibility and with his skippers he has so far added valuable 69 runs for fourth wicket. Mahela Jayawardene, however, kept faith in his regular bowlers and Mendis and Muralitharana are the only successful bowlers. They shared two wickets that fell to the bowlers.
