Zulqarnain Haider led a dramatic revival by Pakistan as England wilted. The tourists reached 291-9 at stumps to lead England by 112 runs in the second test. Haider,who was reprieved by the television umpire after being given out lbw first ball,hit 88 from 200 balls with 15 fours. Saeed Ajmal contributed 50 off 79 balls,leaving Pakistan with an outside chance of victory with two days left. Graeme Swann took career-best figures of 6-60 and bowled 20 maiden overs but England's hopes of a quick victory were frustrated after it had Pakistan reeling on 153-7. The tourists began the day on 19-1,needing another 161 runs to avoid an innings defeat. It was a difficult start to the session for England's Stuart Broad,who celebrated after claiming to take Azhar Ali's wicket in his first over. Without appealing to the umpire Broad high-fived his teammates,but England didn't ask for a review when Ali was subsequently given not out. Replays showed the ball had clearly missed Ali's bat. Imran Farhat was dropped by Paul Collingwood at third slip off a ball from James Anderson and then hit on the helmet by a delivery from Broad. Pakistan resisted for 54 minutes but the breakthrough came when Swann,who hadn't bowled in the first innings,replaced Anderson for the 30th over. Swann's third ball turned sharply to bowl Farhat for 29 and in his next over the spinner bowled Ali for 19. Shoaib Malik didn't ask for a review when he was given out for 3,caught behind to Finn off his glove in the 39th over,even though replays proved inconclusive. In the next over Umar Akmal was lbw to Swann for 20,this time after an unsuccessful review. Haider,who was out first ball in the first innings,was given out lbw to the next ball,but this time the review showed Swann's delivery was missing leg stump. Umar Amin (14) was out in the third over of the afternoon session,stumped by Matt Prior off Swann after an umpire review. Swann bowled 11 consecutive maidens and 67 dot balls in a row,but Haider and Aamer showed admirable resistance. Aamer took 24 balls to get off the mark and was on 1 when Swann found his edge in the 56th over,only for the ball to fly off the tip of Prior's glove before Collingwood dropped his second catch of the innings. Haider advanced to 18 in the 61st over when he was given not out caught behind to Broad,prompting England to waste its final review. England's frustration grew and in the 63rd over Broad appeared to hurl the ball at Haider,hitting him in the midriff. That prompted both the umpires to warn England captain Andrew Strauss about Broad's conduct and in the next over a poor throw from Broad cost England the chance of a run out. Alastair Cook dropped a difficult chance from Aamer off Collingwood in the 71st over and the next ball found Aamer's edge and flew through the slips,leaving Pakistan 29 runs behind at tea. The partnership of 52 was broken four overs into the evening session,when Aamer was caught by Strauss off Broad for 16,after 117 balls. However,Haider reached his maiden test 50 from 150 balls with a four through midwicket in the 91st over and his partnership with Ajmal gave Pakistan hope of setting England something more than a token target. At times Haider rode his luck,with one four from Anderson just eluding the bowler's hand. Haider and Ajmal put on 115 for the eighth wicket and Ajmal reached his maiden test 50 in the 108th over. Ajmal,whose previous highest score in a test was 10,was finally caught off Swann in the slips by Collingwood in the next over. Umar Gul (9 not out) came out to bat with Azhar Ali acting as his runner,but Haider went in Swann's next over,caught by Strauss diving at mid-off. Mohammad Asif (13 not out) hit successive boundaries off Swann in the penultimate over and Gul smacked Broad's last ball for four to crown an impressive fight back by Pakistan.
