Stokes charges Naseem and hits his first ball of the day for six
Those of you on Twitter will likely have seen a clip of Jack Leach hitting a reverse slog-sweep for six in the County Championship last summer. I don't think it'll be long until we see that but for now he's got Naseem Shah to deal with.
Still no sign of the injured Haris Rauf.

Buzzers!
Jack Leach should be run out before scoring. Instead, he gets four via overthrows from Imam-ul-Haq.
Babar is up to seething on the anger scale.

Jacks was shaking his head walking off. He was trying to get over the fielder but hit it right to mid-wicket.
Jacks c Naseem b Ali (Eng 641-8)
Caught at mid-wicket! Will Jacks becomes the latest to go, and be applauded by the dressing room, after being caught playing an attacking shot.
That wicket will bring Jack Leach to the middle.

The new ball has done nothing except disappear to the boundary.
Jacks 26, Robinson 33
I wouldn't like to have to buy Will a Christmas present. Tough man to please.

Will, Hampshire
A group of school kids are still waving homemade 'I love Pakistan' signs in the stand - their endless enthusiasm unchanged.
Jacks and Robinson have played this smartly, I'd say. When Brook got out there was just a hint England could leave a few out there. This pair had a look for 15 minutes and have now pressed on.

Two minutes.
Will Jacks... that is beautiful. Another boundary and another fifty partnership. This one has come from 54 balls and it hasn't felt like they have really been going for it.
Scratch that. After having a word or two with England's debutant, Naseem is smacked for four by Jacks.
Good news for Pakistan - and any hope of something in the realms of a competitive contest.
Naseem Shah is going to have another bowl.

The new ball has been taken in the middle of this over. Babar has probably thought Robinson is batting too comfortably for his liking.
Jacks 13, Robinson 26
Pakistan have taken the new ball!
Ollie Robinson's response? Flogging Mohammad Ali - the not very fearsome seam bowler rather than legendary boxer - for two fours.
Pakistan have removed Stokes, Livingstone and Brook and still can't catch a break.

It's been pretty evenly poised this morning. We've seen some unbelievable hitting from Brook. Pakistan have brought themselves back into the game and now they need to get Jacks out.
These are the things I'm here for. I'm still finding pine needles in my car from 2018.
England's number nine is reverse sweeping and the 600 is up. They have scored 102 in an hour and 10 minutes. Times have changed.

Not a buying tip, but one for transportation. Stick an old duvet cover over your tree in and out of the house to avoid the drop of pine needles. Yes, I did learn that via the live text.
Jacks 12, Robinson 9
I don't want to heap more misery on Pakistan fans but Naseem Shah, his beautiful quiff hidden by a floppy hat, is grimacing after throwing the ball in from the deep.
He has taken all three wickets this morning and the scoring has hit a relative lull.
