Colombo: Debutant Fawad Alam scored an unbeaten century as Pakistan produced a remarkable turnaround to claw their way back in the second Test against Sri Lanka on Monday.
The tourists, who were bowled out for 90 in their first innings, hit back to dismiss Sri Lanka for 240 and then cruised to 178-1 in their second knock by stumps on the second day.
Left-handed Alam led the way with a determined 102 not out to give Pakistan a lead of 28 runs with nine wickets in hand on a dry pitch that appeared to have eased out under the hot sun.
The fearless 23-year-old from Karachi moved to 98 by lofting left-arm spinner Rangana Herath for a six over mid-wicket and then flicked the next ball for two runs to reach the coveted century.
Alam put on 85 for the first wicket with Khurram Manzoor, who made 38 before he was caught behind by wicket-keeper Tillakaratne Dilshan off Herath.
Skipper Younus Khan, who was dismissed for zero in the first innings, was unbeaten on 35 at stumps after adding 93 for the unbroken second wicket with Alam.
Sri Lankan captain Kumar Sangakkara rotated his seam and spin attack in short bursts to gain quick breakthroughs, but Pakistan's batsmen were not found wanting a second time..
Gul set about keeping Pakistan in the contest by taking 4-43 from 18 overs, including the scalp of Sri Lanka captain Kumar Sangakkara for 87.
Off spinner Ajmal bowled unchanged to finish with 4-87 from 28 overs.
Sri Lanka, resuming on 164-3, added 13 further runs before Thilan Samaraweera (21) was run out by a direct hit by Mohammad Aamer at mid off.
Gul then struck a big blow for Pakistan with a fine delivery that cut back between bat and pad to bowl Sangakkara.
Tillakaratne Dilshan started positively with 20 from 34 balls before being given out caught behind off Ajmal, a decision he appeared far from happy with as he trudged off.
Gul also accounted for Nuwan Kulasekara (11), who as caught at slip, and next ball caught Rangana Herath off his own bowling.
After lunch Thilan Thushara was trapped lbw for one and then Angelo Mathews was out for 27, caught at short cover as he tried to farm the strike and protect last-man Ajantha Mendis
Brief Score: Pakistan 90 & 178/1 (Fawad Alam, 102*, Khurram Manzoor 38, Younis Khan 35*) lead Sri Lanka 240 (Sangakkara 87, Umar Gul 4-43, Ajmal 4-87) by 28-runs.
