Ooh! Cook goes for a cut outside off stump but the ball lifts a touch, and he's lucky to not get an edge on it. He tries the same shot a few deliveries alter and this time the ball stays low, and Cook can crack a couple of runs away.

England have all the aces, with South Africa needing to win this Test match. There's no need to take any risks, England will just tick over. Just try and avoid the good deliveries, stay nice and tight at the crease. If the bad ball comes, put it away.
Rabada 2-2-0-0
Keaton Jennings, after every delivery, is wandering towards short leg, eyes focused, puffing out his cheeks and offering himself some advice. Rabada bangs in a bouncer but it doesn't rise, the ball just skimming along the back of Jennings' helmet as he crouches down. Jennings prods and pokes, coming forward and meeting the ball with the middle of the bat, as he sees out a maiden.
Shall we cast our minds back to 2015 for a minute? Heady days.

Morne Morkel does what he's done all series - misses the bat with an absolute peach, and then gets struck for four! Stupid game, cricket. Cook tentatively prods forward and the ball just kisses the daylight between bat and ball, before Morne serves up some nonthreatening stuff on the pads and Cook clips it away for a boundary. The next ball from Morkel keeps low, and Cook jabs his bat down, before a leading edge from the same man goes racing away to the third man boundary. An unimpressed Morkel does his best double teapot.

Beds in one corner, sofas square of the wicket. You'll find wardrobes at mid-off and kitchen appliances behind the pavilion.
Here's Kagiso Rabada - and ooh, his first ball nearly takes Keaton Jennings' outside edge! Jennings just hung his bat out in a pokey sort of defence, playing away from his body, and the movement off the pitch swung the ball away from the edge. Rabada grins at his opponent while Jennings meanders over to short leg for a quiet word with himself. There's some nice carry from Rabada, the ball nipping through to de Kock at about waist height, and Jennings leaves as another delivery rises over his stumps. Maiden.

This is not the worst pitch to bat on. There will be a little bit there, but it will be alright for the England openers. You know it will be slow, giving you more time to adjust and play the ball late. If anything, the odd ball will keep on the little low side, than bounce at you. You stay in, you play. For Jennings, he just has to get in. Play until lunch, get himself a nice little 30.

The first ball of the innings is a little leggy from Morkel, but he then strikes Cook on the pad as he goes shuffling across his stumps. Both Morkel and teh two slips appeal but that was always sliding down, although Cook did get into a bit of a tangle trying to nurdle it away. The ball races away for four leg byes, and Morkel zips his way through a tidy over.
As Morne Morkel prepares to open the bowling, here's how this morning panned out for South Africa. First, a boundary...
And then a wicket...
A quietly animated Faf du Plessis leads his side's huddle, slapping Hashim Amla and Quinton de Kock on the back as he gesticulates. Alastair Cook waits for the nod and then he and Keaton Jennings make their way down to the pitch, applauded all the way by the hardy Old Trafford crowd.
We're under way in the County Championship too, with the grand old competition back up and running after a break to accommodate the T20 Blast. We have commentaries and live text of seven matches here. Enjoy!
Geoffrey is making the very valid point that this innings is all about numbers two, three and five for England. Ignore the fact there's rain around and focus on Keaton Jennings, Tom Westley and Dawid Malan. Can England solve the questions about their batting that have been swirling around since this series began?

The morning after the day before. If Saturday was a booze-filled riot, Sunday is respectful and sedate. Queues not as long, noise not as loud, cups of tea rather than pints of lager. Everyone needs a rest once in a while.
Anderson lead England off to a hearty round of applause, before Cook and Jennings went charging up the stairs to get ready to bat. This is a big moment for Keaton Jennings - there's no Philander in the South Africa side but it's cloudy, the new ball has moved around today and it must be playing on his mind that this is his last chance to impress.

The only time South Africa made decent runs, they won the Test at Nottingham. You have to make enough runs to help your bowlers. They've got good seamers and a spinner, but they can't bat.
South Africa are all out for 226, which means England have a first innings lead of 136. Broad finishes with 3-46 and Anderson 4-38, while Moeen has 2-57 and there was a solitary scalp for Toby Roland-Jones.

That was a good catch, wicketkeepers with gloves - you have to leave it to them. Cook, at slip, did the right thing.
Olivier c Bairstow b Broad 4 (SA 226)
Gone! No five wicket haul for Anderson in this innings! To prove that I absolutely don't know what I'm talking about, Broad whizzes down a short ball, Duanne Olivier decides to take it on and he slaps a loopy pull shot skywards. It hangs in the air for a long time, giving Bairstow plenty of time to think about it, but he takes a good catch to end the innings.
