Good question, Pete. We are not sure - I'm sure the question will be asked at close.

Just the two singles from Will Jacks' third over.

Pakistan ticking along nicely.

safcpete: Any clues why Robinson hasn’t bowled yet?

It certainly seems lighter at this stage than it was in Rawalpindi, though you can also start to see some mist creeping in.

England will be desperate to try and snare one more wicket before close.

50 for Babar Azampublished at 22.1 overs

Babar Azam pushes the ball into the leg-side for a single to bring up his half-century from 57 balls.

The crowd goes wild and Babar raises his bat in appreciation.

It has been a perfectly paced innings so far.

The umpires are not consulting about the light. The sun is still reasonably high and we might get play through till 5pm local time.

Joe Root probes outside Saud Shakeel's off stump, looking to get one to hit those foot marks.

Nothing doing though. Pakistan are ending this day on top.

Pak 81-2published at 21 overs

21 overs

The roar says it all.

Babar Azam has seized on a full delivery from Will Jacks and smashed a half-volley over mid-on for six.

Every over seems to contain a bad ball at the moment and Pakistan are fully cashing in.

You can see two areas of rough. Something for the bowlers to aim at. This pitch is bone dry.

Oof, that turned.

Joe Root switches ends and gives it a bit of air to Saud Shakeel. It tempts Shakeel into a wafty drive and the ball lands in the bowlers' foot marks before jagging away from the Pakistan batter.

More frustration for England though as Root drops the next delivery short and Shakeel cuts away for four.

There's an appeal but Aleem Dar is not interested.

That spun a long way, bit of encouragement for the bowler.

Babar Azam nudges a single off the first ball to bring the left-handed Saud Shakeel on strike.

Jacks then really gets one to turn and hit his pads, prompting a half-hearted appeal that Aleem Dar turns down.

Jacks then undoes his good work slightly with a short ball that Shafique can cut away for three.

Just as you say that, Andy. Here is Will Jacks.

Andy Cook: Surprised they're bowling Root before Jacks. Jacks has been picked for both batting and bowling whereas Root's wickets are usually seen as a happy bonus to his incredible batting.

That's even bigger from Saud Shakeel as he goes for the heave towards deep mid-wicket, though it bounces just short of the boundary rope before rolling over it for four.

He plays a similar shot two balls later but a little squarer and it races to the rope for another boundary.

Babar Azam is looking in great touch. He charges Joe Root and dispatches him confidently back over his head and away for four.

Babar is now on 41 from 47 balls.

Would anyone else feel nervous if there were several birds flying menacingly overhead swooping down every now and then?

There are now four catchers close in as Jack Leach bowls his eighth over.

Saud Shakeel gets off the mark with a push through square leg.

One of those kites started to swoop in on the ball but Jacks picked it up and threw it back. That was the end of that excitement.

There you go. The BBC Sport readers' hive mind does it again.

Every day is a school day.

Back on solid ground, Joe Root races through another maiden over.
