Pakistan in the driving seat

The third-wicket pair reordered the balance between bat and ball to shut England out for 72 overs, and counting, to close on 222 for two - with a lead of 180 - after 22 wickets had fallen inside the first four sessions.

Andrew Strauss' tourists must therefore contemplate a fourth-innings target significantly in advance of the one which proved well beyond them on the way to series defeat in Abu Dhabi last week.

Younus (115 not out) and Azhar (75no) joined forces at 28 for two in the 10th over, still 14 runs behind after Strauss (56) had helped his team into what seemed then a useful mid-match advantage.

They then simply wore down England, and their bowling resources - gradually until tea and more adventurously thereafter in an unbroken stand of 194. Theirs is by far the biggest partnership of a series previously characterised by an apparently unstoppable clatter of wickets, punctuated mostly by DRS scrapes rather than any permanence on the part of the batsmen.

Younus took 106 balls over his first 50 but only 60 more to reach his 20th Test hundred, which contained 11 fours and a six.

His ultra-patient partner provided a perfect foil at the scene of his only Test hundred to date, against Sri Lanka last year, in a 246-ball stay as Monty Panesar and Graeme Swann became ever less threatening on this fair pitch.

James Anderson was successful at least in stemming the flow of runs, more so than his fellow seamer Stuart Broad - who left the attack after taking a blow to his foot from a straight drive but was able to return to bowl the last over of the day with the second new ball.

In the end, it was as much as England could do to collectively limp to stumps in the hope of conceding as few runs as possible and finding some respite early on Sunday.

Earlier in the day, Strauss' continued defiance had earned the tourists a first-innings lead of 42, but Abdur Rehman's second successive five-wicket Test haul still helped to hustle England out for 141.
