SHARJAH (AFP) - Off-spinner Saeed Ajmal took two wickets in an over to check Sri Lanka's victory bids on the fourth day of the third and final cricket Test against Pakistan at Sharjah stadium here on Sunday. The wily-spinner dismissed Angelo Mathews (13) and Kaushala Silva (nought) in the final hour to stop Sri Lanka who were on the right track after half-centuries by Tharanaga Paranavitana and Kumar Sangakkara. Sri Lanka, aiming to level the three-Test series after losing the second Test in Dubai by nine wickets, will seek some quick runs early on Monday, with Paranavitana unbeaten on 66 and Kosala Kulasekera on four not out. They lead by 237 runs with five wickets intact on a weary pitch which helped the spinners as Ajmal, Mohammad Hafeez and Abdul Rehman troubled the batsman with spin and deliveries that kept low. The first match in Abu Dhabi ended as a draw. Paranavitana, dropped on two and 25, batted valiantly to keep Sri Lanka in the hunt as they lost Tillakaratne Dilshan (four), Sangakkara (51) and Mahela Jayawardene (20) while in search for quick runs. Paranavitana has so far hit four boundaries and a six during his enterprising 156-ball knock. Paceman Umar Gul provided Pakistan with a quick breakthrough as he dismissed Dilshan, caught in the slip off the fifth ball of the innings. Sangakkara, who collected 516 runs from the six innings at an average of 86 in this series, added 75 for the second wicket with Paranavitana before he was caught off spinner Hafeez, causing a middle-order slump. Jayaywardene also fell to Gul, trapped leg-before wicket. Earlier, left-arm paceman Chanaka Welegadara took his maiden five-wicket haul, finishing with 5-87 after Misbah-ul Haq missed his hundred by just 11 runs as Pakistan were dismissed for 340. The lanky paceman improved on his previous best of 4-87 he took against India at Ahmedabad in 2009. But despite Welegedara's effort, it was Misbah's fighting knock of 89 which brought Pakistan closer before the 37-year-old right-handed batsman fell 10 minutes before lunch.
