"There are 140 overs for South Africa to bat to force the draw. If they do bat that long, they might be in sniffing distance of winning."

Well, it might have been a bit stodgy towards the end, but that's still a job well done by England. The openers failed again, but Nick Compton and Joe Root set them up solidly, before a bit of biff from Bairstow saw them through a very satisfactory second-innings total. South Africa will have to score 416 to win - two runs shy of the world record fourth-innings chase. England in the box seat...

Maddy Raman:‏ It's silly still batting when lead is 400 but plain stupid to send your strike bowler in when he could be taking wickets.

Laurence Bowyer: ‏What is to be gained from Finn batting?! Shocking non-declaration from Cook. 

Fenners:‏ Lay off bagging Cook. If he declared early & we end up losing he'd be pilloried for it. Need 400 lead at least. Good captaincy.

So now we're going to see South Africa's openers bowling in tandem before they go out to open the batting. Part-time left-armer Dean Elgar comes on to have a twirl. Bairstow marmalises him inside-out over the covers for four, then slogs him over the mid-wicket boundary for a maximum. I reckon Alastair Cook is going to give him the chance to get his maiden Test ton here...

Andrew Samson
BBC Test Match Special statistician

"Alastair Cook has declared six times in the third innings of a match. The lowest target he has set is 390."

Finn blocks out the final two balls of the over. This is silly, isn't it?

"Get declared. 400 is a lot to get. I'm not sure England need any more. South Africa are only trying to save the game."

"He was just trying to be positive. Woakes played very nicely and he should be pleased with that."

Aha! I've spotted Cook. He's on the upper tier of the England balcony, sitting in front of a laptop. I hope he hasn't got series five of Game of Thrones on there - we could be here for hours if so. At least Jonny Bairstow is showing an inclination to get on with things - he's just absolutely pasted Piedt over the midwicket boundary for six. England's lead passes 400...

"This is Bairstow's best innings since he got 95 and 54 against South Africa at Lord's. He's a better player when he's uninhibited."

Bairstow finally breaks the tedium by lofting Van Zyl over the top. Balcony Watch: Buttler snoozing, Ottis Gibson scratching his nose. Cook? Nowhere to be seen...

Graeme Swann
Ex-England spinner on BBC Test Match Special

"Still no sign of a declaration. This is enough. If you were fielding and ahead of the rate, could you just refuse to bowl? If you're 10 minutes ahead, sit down for 10 minutes."

How do you write a yawn in text? Any suggestions? I'm not sure but this is getting a bit snoozeworthy. Two singles from Piedt's latest.

"It's that turgid period now. Runs are coming at one a ball. South Africa don't care. It's almost pointless cricket until Alastair Cook decides to have a bowl."

Amla goes back to Stiaan van Zyl for some more military medium. About as much venom in his bowling as a grey squirrel. Still, Bairstow and Woakes show his trundlers probably more respect than they merit - just two singles from the over.
