Geoffrey is right, James Anderson looks like a different beast to the first day. Looking again, Elgar could have left that on length, there was no way the ball was going anywhere the stumps. Hashim Amla is the new man, harried into defence by Anderson.

"He was squared up, Elgar. A piece of cake, Anderson turned him round, bowling round the wicket.

Stuart Broad shares the new ball, with the Barmy Army breaking off from a chorus of Jerusalem (complete with actions) to sing his name. He's on the money, off stump and around, before the final ball flies over the head of Cook.

James Anderson got a talking to at the end of his first over - he's been perennially in trouble for running on the pitch in this series. Another observation - Jonny Bairstow's whites are very snug. The outlines of pecs and box are uncomfortably visible.

Mike Ball: Imagine the runs Moeen Ali could get if he was up the order and not always batting with the tail. His class is wasted at eight.

David Fletcher: Moen wasted at eight. Drop Hales, move Compton and Moen up the order.  

It was a very dodgy second innings that cost South Africa in Johannesburg, but you get the feeling that Stephen Cook would rather be tortured than let that happen again. He's happy to leave an Anderson over which looks pretty, but doesn't threaten. When Anderson is too short, Cook punishes.

The players are out there again. James Anderson the ball, Stephen Cook is on strike. Can England strike tonight? If they don't, the result will be put beyond doubt. 

Can England get back into this match? Yes. It's still a good time to bowl, but you'd think that they need to bundle South Africa out for under 200. The target England could chase in the fourth innings is nudged slightly higher if Kyle Abbott is injured.

"South Africa have had one of the best days of the entire series today. They bottled England up. 

"It's the first day that has cost England. There was no energy, no rattle. Apart from Stuart Broad it was tepid. They gifted South Africa 200 runs."

John, Swindon: The use of point one, point two etc to describe partly completed overs. Surely 3 balls is 0.5 overs, 5 balls 0.83 overs etc.

England's 342 doesn't look great against South Africa's 475, but I have a theory that is actually about par.

Most of England's top order were got out - only Taylor threw his wicket away. When they fielded, England dropped too many catches, including each of South Africa's three centurions. Hold them, and they might have even had a lead.

"With Dale Steyn and Vernon Philander out of the picture Kagiso Rabada has really played his way into the team. It's fantastic to see, good for the future of South African cricket and good for the country as a whole."

Kagiso Rabada leads South Africa off the pitch after his figures of 7-112. They are the best figures against England since readmission.

"A lead of 133 is big on a wicket like this. Moeen Ali played really well to get England as close as they are. England will come out and try to turn it around with some early wickets.

"South Africa  will have to come out and face the music with the new ball."   

Hannah Dixie: Surely all balls are "arm balls"??

Ben Prior: How did getting out for naught become duck / golden duck?
