Abu Dhabi: England opener Alastair Cook missed a century by six runs and Jonathan Trott made a half-century before Pakistan hit back with four wickets in the last session in the second Test.
Cook was trapped leg-before-wicket off spinner Saeed Ajmal for 94 -- his fourth nervous ninety dismissal – and added an invaluable 139 for the second wicket with Trott (74) to take England to 207-5 in reply to Pakistan's 275.
Ajmal took three of those last four wickets, dismissing Kevin Pietersen (14) and Eoin Morgan (three) in the last over for the addition of four runs to bring Pakistan back into the game after Cook and Trott had foiled their bowling.
At the close on the second day, Ian Bell was unbeaten on four with England needing another 50 runs to overhaul Pakistan's first innings total on an Abu Dhabi pitch that is helping bowlers.
England, aiming to level the three-Test series after their 10-wicket defeat in the first match in Dubai and maintain their world number one ranking, will look to out-of-form Bell and the rest to give them a lead on Friday.
Pakistan, meanwhile, will hope that Ajmal, who has figures of 3-67, can bowl England out early.
Cook and Trott had negotiated the dangerman Ajmal well, before both fell to spinners.
Trott missed a turning delivery from Abdul Rehman that spun across his bat and hit the off-stump. He hit seven boundaries off 158 balls.
Cook looked certain to reach his 20th century as he hit Ajmal for his 10th boundary to move to within a stroke of the milestone but two balls later he missed a ball that kept straight and hit him in front of the stumps.
