Jonathan, Manchester: Re John Swindon, my old maths master and cricket coach may end up turning in his grave if I get this wrong - for bowling stats cricket is scored in base six, but for everyday life we use base 10. It's just one of those things that make me love it.

Amla has been patted on the back and told to get on with it. He's back facing up to Stokes, who charges towards a stand of blue seats that are less than half full. Good length from Stokes, with Amla plodding forward to push back a maiden. The trooper.

"That delivery flew up on him. Hashim Amla has got strapping round his right thumb - exactly where Stokes' delivery hits him. You can see there's a bruise come up straight away, and I think he's cut a nail. It looks like he's going to stay out there."

"Hashim Amla is in a spot of bother here, he really is."

Ben Stokes is indeed into the attack, immediately causing Hashim Amla some extreme discomfort. Bounce, taken on the right thumb. The glove is off, the physio on. Slow-mo replays make it look extremely painful. Leather on hand, the thumb rattling around. It's jammed the nail and drawn some claret.

AB de Villiers waits in the changing room. Pads on, head on chin. Ben Stokes goes through some looseners as Anderson pumps in, swinging the ball this way and that. Cook, who has been nothing but impressive in this match, gets a couple through the off side thanks to a Compton misfield.

"England will be wishing they had bowled like this in the first two sessions. We'd have a totally different game."

Broad angles in to Cook, who has no fewer than six close catchers for company. A short leg and leg gully suggesting that Broad may test the body of the debutant. Has the created some doubt? Cook doesn't look so certain coming forward. It's getting darker.

When I say it's gloomy, the floodlights are on. There are also a few drops of rain visible by the electric scoreboard. Three slips, a gully and a short leg for Anderson, who beats Amla with a hopping away-swinger. It's a time to bowl - South Africa would take some rain right now.

"I don't think we'll get all the 23 overs scheduled for tonight, so England will run in really hard, chasing the game. They need three or four wickets tonight - if they can get them the game will really open up. But the chances have got to stick."

After this set by Broad, there are still 23 overs left in the day. We could go on until almost 17:00, but I've seen some suggestions that the light won't even hold for the next hour. It is pretty gloomy and there's no chance England will get the slow men on to prolong their time out there.

"Diving, one hand, that is very difficult. People will put that down as a chance for a catch - if it is a statistic, I can't disagree, but you have to qualify it. It didn't go to hand at all easy. Wonderful bowling from Anderson."

Dropped! It's a very tough chance to Alex Hales, but you've seen them taken. A thick edge by Hashim Amla off James Anderson, speeding towards third slip. Hales dives full-length to his right, just getting his fingertips on it. If he'd held it, it would have been similar to Ben Stokes at Trent Bridge. He didn't and Amla has a life.

I'm hearing that Kyle Abbott has a tight hamstring and might not bowl again in the match. Is there any chance of these teams getting through a match without a fast bowler breaking down?

Mike Bell: Jimmy is running in with vim, vigour, vitality and velocity. V much better than in first innings.

Before Anderson took that wicket, I was wondering if bowling in the third innings when the opposition have a huge lead is one of the most demoralising jobs in all sport. The questions still stands, but England will have been lifted. Still any more than 200 for South Africa in this dip and you feel they will be too far ahead. Cook nudges them nearer by easing Broad through mid-wicket for three.

Rachel T: Yes Jimmy!! We need his A game!
