Target 167
Four more! It's the same shot again from Willey as Rauf tries the slower ball but to no avail.
England are back in with a sniff.
Target 167
Cheeky from David Willey. A reverse scoop and the first ball of the Rauf over runs away for four.
Daniel Norcross
BBC Test Match Special
He's knocked Willey over with that yorker! High pace and skill from Rauf.
Target 167
To make matters worse for England, Hasnain has got the ball reverse swinging and Willey does well to dig out a yorker to end the over, even as it knocks him off his feet.
England need 45 from 24 balls.
Target 167
Boundaries are hard to come by at this stage but Dawson and Willey are running aggressively between the wickets.
Twos from the first two deliveries of Hasnain's over. Well run but Willey would have been gone with a direct hit from the second of them.
That's quite generous to England, I'd say, Aatif.

Pakistan are marginal favourites right now.
Target 167
David Willey and Liam Dawson have to deal in singles for the rest of the over. Both are very capable batters but neither has had much in the way of match practice with the bat of late.
England need 51 from 30 balls.

That's a huge wicket for Pakistan! Brook was looking so dominant and he will be furious with himself.
Daniel Norcross
BBC Test Match Special
That could be a game-changing wicket.
Brook c Hasnain b Wasim 34 (Eng 113-6)
Caught at fine leg. Brook tries to help the ball for six as Mohammad Wasim strays leg side but can only pick out the man on the rope.
That is another huge wicket for the home side. England lose their last frontline batter with 55 runs still needed.
Target 167
Top shot from Brook, whipping the ball through square leg for four. A very wristy shot to find the gap.
England need a few more of those.
Aatif Nawaz
BBC Test Match Special commentator
Is there a twist left in this tale?
Target 167
David Willey is in for England and while he is more than capable of clearing the ropes, he might need a bit of time to get himself settled. Do the tourists have that time?
A very good finish to the over from Nawaz, just dot balls.
England need 59 from 36 balls.

The ball goes through Moeen Ali and Pakistan needed that wicket. He walks off with a disappointing look on his face.
Moeen b Nawaz 29 (Eng 106-5)
Big, big wicket for Pakistan.
Moeen Ali advanced to Mohammad Nawaz, the spinner saw him coming, darted it in and hits middle stump. The England skipper missed with a big shot aimed over the leg side.
The game swings back towards Pakistan.
Brook 28, Moeen 29
The crowd were up a couple of times in that Iftikhar over as Brook hit the ball back past the bowler in the air - those in attendance not in a position to spot that the ball had already bounced.
Anyway, that boundary for Moeen keeps the game exactly where it has been for a few over - in the balance with England needing just shy of nine runs an over.
Smoked over extra cover for four. Brilliant from Moeen Ali to bring up the 100 for England.
He's so good to watch when he's on form.
Alex Hartley
Former England bowler on BBC Test Match Special
England need a couple of boundaries and Pakistan need a couple of wickets.
Target 167
Wasim makes an excellent diving stop near the rope to deny Moeen a boundary from the penultimate delivery but gives England the runs right back next ball.
The fielder clearly doesn't pick it up and has a hand protecting his face as the ball bounces past him.
England will be thankful for that boundary, it keeps them in touch with the rate.
