And that's where I'll depart. Enjoy your Friday evening and join us again in the morning. Goodbye.

So, we begin again tomorrow morning, with England looking to push on to 500+ and Pakistan hoping for early wickets to avoid a long day in the dirt.

For all that I said about Cook and Root, I can't say the same about Hales, Vince and Ballance.

Hales is not the finished article. He's trying hard but he was playing way in front of his pad and he got bowled. It's about footwork - it's very simple.

There are plenty of batsmen to come - on paper. They have batted Yasir Shah out of the game today, but tomorrow the batsmen are gone and it could be different.

England batsman Joe Root on Sky Sports: "We're in a good position now. It's about making the most of it tomorrow, make sure we get partnerships going. Today we played a lot straighter. There was some frustration from before of not getting on for a big score. It was nice to do so today."  

England captain Alastair Cook on Sky Sports: "It was a good day. For Joe also to get a big hundred is vitally important. It was a belting first-day wicket, but there's signs it might wear and tear so we've got to make them most of batting first. I thought we played at a better tempo today."

It was left to Chris Woakes (the world's best nightwatchman?) to bat through the rest of the day. England sleep on 314-4, an ideal start in their bid to square the series.

Vince plays the most pretty, handsome cover drives but he can't resist having a dart outside off stump. They got him out twice at Lord's like that and they got him twice here - because he was dropped at second slip. Pretty small scores ain't going to cut it. He can't keep making the same mistakes because the selectors will say, "he hasn't got a cricket brain".

You can see Gary Ballance is a very limited batsman. I don't think anything has changed from when he played before.

It looked like Gary Ballance would accompany Root to the close, but he became the second member of England's middle order to fall to a poor stroke.

But that didn't stop Root from going to his 10th Test ton.

When Cook went on the stroke of tea, it presented an opportunity for James Vince. Twice he tried to pass it up, succeeding on the second occasion.

England will have hurt after losing at Lord's. I thought England's batsmen are not that bad - it's the five inches between their ears that count.

Root and Cook played splendidly - they showed patience, concentration, judgement. Only a handful of balls got past the bat. They made the leg-spinner bowl a lot of overs, tire him out and not give him any easy wickets. It was just a quality performance. They weren't flawless innings but they were excellent.

It was Cook who won the race to a century, notching his 29th Test ton. He's level with the GOAT, Sir Don Bradman. 

...after shot.

Alastair Cook and Joe Root weren't wasting the chance to bat on an Old Trafford belter. Cook steady....

Joe Root has played impeccably - a copybook innings. It's one thing winning the toss and it's another turning that into a winning position. Don't worry - Root will be hungry for more tomorrow. There could be a really big score on the horizon if he gets in tomorrow.

One man who might not look back on today too fondly is Alex Hales. If we go right back to the morning session, he was thoroughly worked over by Mohammad Amir before losing his middle and off stumps.
