Now Ben Duckett has joined the six party! It is too short from Mohammad Hasnain and the ball sits up perfectly for Duckett, who clubs the ball over square leg.
England racing to the finish here.

Harry Brook is clearly unaffected as he has just leapt onto a Haris Rauf delivery and clubbed the ball through the covers for four.

Benjamin Watts: Harry Brook is quite good at cricket.
Eng 172-3published at 16.4 overs
Ouch. Harry Brook has looked to launch the ball into next week, but it has come off his gloves and somehow become lodged in the grille of his helmet.
The physio will come out to check on Brook but he has a big smile on his face so I think he will be OK.

50 for Ben Duckettpublished at 16.2 overs
It's a first T20 half-century for Ben Duckett as well!
He clips Haris Rauf's first delivery off his pads to move to 50 from 31 balls.

He's applauded by his entire team and the fans in Karachi.

It is Harry Brook! He backs away and plays a lovely drive past point for four to bring up his first T20 half-century from just 24 balls.

This won't either! Harry Brook has just carved Shahnawaz Dahani for a monster six.
Both players are now on 49. Who will get there first?
Eng 158-3published at 15.3 overs
A bit of fire from Shahnawaz Dahani as he hurls the ball back at Harry Brook's stumps after his fielding his mis-timed drive.
Next ball Brook plays a delicate late cut that files through where first slip would be for four.
That won't help Dahani's mood.

England captain on BBC Test Match SpecialIf England carry on then they are likely to hit the same score they did yesterday.
The difference yesterday was the Pakistani batters hit those really big match defining shots and England didn't.
Duckett is showing England management and coaches what he can do.
Eng 143-3published at 14.2 overs
One of the most bizarre shots you will ever see.
Ben Duckett backs away as he goes for the pre-mediated paddle shot, Mohammad Hasnain follows him, but Duckett still manages to loft the ball over the wicketkeeper for four.
They all count.
Eng 135-3published at 13.1 overs
That has gone miles into the sky!
Harry Brook seized onto a short Haris Rauf delivery and absolutely creamed the ball away over square leg for six.
Brook was onto that in a flash, brilliant shot.
That's the 50 partnership off just 29 deliveries.

Dave Foot: Re: Malan. We have any number of batters who, on their day, can be very effective in T20 cricket - therefore the question becomes less which is better and more how do we get the best out of them? Playing with freedom only works if you know you've got backing.
You only have to look at his Hundred season (and his IT20 record) to know he deserves his place in the England team. And there is a lot to be said for a settled team.

Usman Qadir serves up a full toss and Ben Duckett helps himself by powering the ball through backward square for four.
Usman ends the over with an even worse delivery. It is short, it is wide, and Harry Brook can sweep fine.
The run rate is starting to edge up towards 10 again.

There's a smile on Ben Duckett's face as he sweeps Mohammad Nawaz - again - and the ball flies off the top-edge and over the wicketkeeper for four.
He's at it again next ball!
It is a better-timed sweep-shot this time though and it fizzes through the on-side - as he intended - for another boundary.

BBC Test Match Special commentatorThat was an outstanding shot from Brook!
Eng 105-3published at 11 overs
That's even bigger! It is wider this time so Harry Brook has to reach for the ball but he still has enough power to send the ball way over extra cover.
England needed that too as the run rate had just started to slow a touch in the previous few overs.
Eng 96-3published at 10.2 overs
Harry Brook has just skipped down the track and absolutely smashed Usman Qadir right back over his head for a huge six - the first of the match.
Brilliant shot.
