The effect is to have Moeen wafting outside off - neither forward or back, with minimal footwork. The left-hander, firmly back in his crease, manages to grab a couple down the ground to prevent a maiden.

Jay: Being dropped by the keeper in this match is a sure sign that a batsman will score a century. Sit back and watch the Woakes show?
Is now a good time to remind you that the follow-on target is 276? It's no gimme for England with South African tails up like this. Woakes, first-class batting average 36, pushes a couple into the off side then pulls a Rabada bouncer to reduce the deficit by four.

"Chris Woakes' footwork was not great. There's nothing wrong with having a go at it but you've get to get your feet across. Dance! "England are in a bit of trouble aren't they?"
Eng 253-7
Morkel has Woakes sniffing some leather courtesy of a couple of bouncers, then finds a top edge as the new man cuts. A leaping Quinton de Kock can't cling on with his right hand behind the stumps. A rare black mark for the centurion.

Andy Donley: This England team is incredibly exciting, but they lack any sense of game management. Attack or die.
Eng 253-7 (trail by 222)
Image source, APStokes let out a primeval roar as he headed back to the hutch. Not a happy bunny. He looked in fine touch this afternoon - a missed opportunity... Chris Woakes, the new man, playing and missing - then putting Moeen in a spot of bother with a scampered single to AB de Villiers. A direct hit would have done for him.

"Beautifully bowled. This kid has got something. The new ball slips at you a bit quicker, it's got the raised seam and hurries on to you.
"But Ben Stokes didn't get right out to it and is cross with himself. He could have got further forward and was late on to it."
Stokes c Amla b Rabada 33 (Eng 252-7)
Image source, Getty ImagesThe new ball has been taken... and so has the catch. And it's that man Stokes who's gone. Kagiso Rabada back into the attack, drawing Stokes into a tentative push outside off stump, and the edge carries comfortably to Hashim Amla at first slip. Rabada has six wickets for the first time in his Test career. What a performance from the 20-year-old.

"Ben Stokes was looking for that. He was onto it in a flash. I think AB de Villlers will like what he's seeing though - watching Stokes going after the off-spinner."
He's got the lot, this lad. That's a perfectly acceptable delivery from Piedt, but Stokes dances down the pitch and lifts him straight back over his head for a glorious six that leaves the cameraman on the banking swivelling to try and film the ball. This is brilliant stuff.
Image source, ReutersThe new ball is available and has been brought out to the umpires. But I don't think South Africa have taken it just yet. Piedt continues. With a long hop. Stokes continues. With a pull for four.

"If there's any doubt with the forecast you probably have to rake the risk of bowling again if there is a follow-on. In an ideal situation from this position you probably bat again, knowing the pitch is only going to get worse.
"There is one crack in particular that really is moving."
Remember Cape Town and that ferocious Stokes assault on Chris Morris? Everybody's favourite ginger is at it again, lashing Morkel through the covers for four. An inside-edged forcing shot on to his pads, then a leg glance for a single. It's a shot a ball at the moment from Stokes. He has 22 from 21 deliveries.

Mark Savile: When was Moeen's last contribution with the bat? Time to step up! (No need to ask when Stokes' was!)
Piedt mixing up his pace from round the wicket. There's turn, but not enough to discomfort Moeen, who plays out a maiden. Back to you, Ben.

"Nobody wants to stop Ben Stokes playing his game but he does have to be aware that he has to get in. There was nothing wrong with that four, it was a beautiful shot, but put those riskier shots on hold.
"He has to be counter-attacking, but only so long as he doesn't do silly things, because England are in trouble."
Morkel resumes at the other end... and Ben Stokes, as if he's been batting for three hours, drives fluently on the up to cover, where the fielder makes a smart, scrambling stop. Good cricket all round. Morkel THEN strays on to Stokes' pads and is whipped over mid-wicket for four. Even the boundary rider can't stop that. "Don't bowl there to me." This promises to be very, very good viewing.

Andrew: Re Gary, Wirall. Each to their own and all that, and there's no doubt cricket's moving towards being all about T20, but to me that game is akin to a pre-season friendly in football. Attractive for a while, but in the grand scheme of things, completely forgotten by next weekend and meaningless in the long term.
The players are back out. Piedt finishes off his over with a dot to Moeen.
