Hashim Amla making me eat my words. First he forces Anderson through cover, then edges a drive for another boundary. Amla has 62 off 139 balls. happy to hang back in the crease, Amla has scored very few runs in front of square in this innings. He has 62 now.

"South Africa probably want four sessions to bowl England out. If they bat at the rate they are now that score could be 360, 370 before tea. That's when AB de Villiers will probably feel he has enough."

If this was England batting, I've got a sneaky feeling that there would be one or two tweets and emails coming our way mentioning a lack of urgency on the batsmen's part. The South Africa innings run rate is 2.4 an over, so the lead would be about 350 by tea if they continued at this pace. Enough for a declaration, with four sessions to bowl England out? One off that Broad over.

James Hornby: England missing Steve Finn here, the man just takes wickets.

Oooh! A couple of scuttlers from Anderson. Bavuma shoulders arms at the first then just manages to jam his bat down on another, straighter one. I wonder what Alastair Cook and Alex Hales make of that.

"We don't really know what is happening with Kyle Abbott's hamstring injury. We have had so many mixed messages from the South African dressing room, but apparently he is going to bowl now."

Broad is wide on the crease and short at Bavuma, who is immaculate in defence. Side on, right back in his crease when playing back, high left elbow, Youngsters, take note. He steers one to gully's left for three to get his score moving after lunch.

Fenners: Woakes showing again how little he contributes to the team effort. May as well play me, I'd get as many wickets.

Flemming Jensen: Not necessarily defending Woakes here, but to all those 'I would get as many wickets as Woakes'-tweeters......no, you wouldn't.

If England are to have even the slightest chance of engineering a win in this game, you suspect their strike bowlers must do something now. Anderson, with three wickets already to his name, attacking Hashim Amla, whose discomfort from that thumb injury is obvious as he lunges forward. A couple bounce slightly more than expected, then one hurries on low to Amla. What were we saying about that uneven bounce...?

"You've got to feel that England are maybe 40-50 from thinking it is too much to win and that they will have to just concentrate on trying to saving the match."

Broad, looking for all the world like a messy-haired teenager who has just woken up, beats Bavuma on the outside edge with a snorter of a leg-cutter. Wasted in every sense. A maiden to get us under way.

So that's where we're at in this game - South Africa leading by 254 and firmly in the driving seat. Stuart Broad to Temba Bavuma. Here we go.

Thanks Stephan. Can't say I meet either of those criteria. But leave this with me. England polish off the rest of this South Africa innings, limit the lead to 300, then rattle off the highest chase in history in Centurion with a session to spare thanks to an unbeaten 186 from Ben Stokes. Or something like that.

Remarkable, inspirational stuff from Hassan Khan on TMS there. I'm not sure if Justin Goulding is either of those things, but he's a safe pair hands for the afternoon session.

Visually impaired England cricketer Hassan Khan: "I also want to take this moment to thank you, Jonathan [Agnew]. When I was learning English it was mighty difficult. Somebody bought me a walkman and during lunch breaks I would flick through radio stations to see what I could find. Over the England v South Africa series in 1998 I listened to five days of Test Match Special. 

"If you are a fan of cricket, come and watch our game. Come and support us because we are all a family."

Jacob Arthur: Hassan Khan is the sort of man that just restores your faith in humanity a touch. What a passionate cricketer.

Daniel Welsby: What an inspiration Hassan Khan is, has made me want to get back into cricket and not take that for granted.

Andrew MarshalDyson: Hassan Khan... my kind of crazy... Inspirational!

BBC Test Match Special

Visually impaired England cricketer Hassan Khan: "From the age of 17 I was this young timid boy who stayed at home, I’d never really stepped outside on my own until I discovered cricket. I used to think if you were blind you could not pick up a bat. I’m now full-time employed, enjoy my cricket, and it’s all thanks to Metro, external and the ECB – over the past few years the difference they have made has been immense."

Visually impaired England cricketer Hassan Khan: “It's an honour to play for my country. Especially when I think about how far I have come. People thought maybe I could become an imam in a mosque, or potentially a beggar if my family died. That, as a child, had a massive effect on me. I felt like I couldn't make a difference to my life and it was horrible."
