Ollie Robinson looks disappointed, thinking he had his sixth wicket of the match, but he is bowling beautifully once again.
James Anderson smiles wryly but the ball does seem to bounce ever so slightly before it settled into his hands.
Do England have their first? They certainly think so.
It's a leading edge from Erwee to James Anderson at fifth slip, he takes the catch very low to the ground but the soft signal is not out from the umpire, which could prove significant.
It's that sharp bounce from Ollie Robinson again, as he strikes Sarel Erwee on the pads. Robinson appeals but it's probably too high, and Ben Stokes doesn't bother with the review.
He is still causing plenty of difficulty for the South Africa batters on this pitch.

South Africa get their first boundary, but it's not a very convincing one.
Anderson draws the edge from Dean Elgar but it bounces just short of the fielders and trickles through fourth slip and gully for four runs.

It has been one of those surfaces where everyone has found it hard to bat on. The only person that has made it look half decent is Ollie Pope.

That was a hostile delivery. Back of a length that jumped out of nowhere.

Ollie Robinson picks up where he left off from yesterday's performance, getting the ball to nip around and beat the outside edge on a couple of occasions. He beats Dean Elgar with a lovely delivery that bounces considerably before whizzing through to Ben Foakes.
If you are just joining us, here are the three England wickets that fell this morning, for just four runs and in the space of 13 minutes.
A quiet start from both sides, as the ball doesn't swing much for Anderson and Erwee plays it cautiously.
It will be interesting to see Ollie Robinson at the other end now, who got the ball to move around plenty yesterday.

The two first innings were completed in 72.4 overs, the fourth-shortest length of completed first innings in Test history.

Sarel Erwee gets the first runs of South Africa's second innings as he clips the ball into the leg side for two.
Well, not many of us could have predicted we would see England bowling again quite so soon. England spoke about batting with intent and building their lead quickly, but they only managed to add four runs to it.
Sarel Erwee is going to face the first ball from Jimmy Anderson.
Andy Zaltzman
BBC Test Match Special statistician
It is only the fifth time in Test history that both sides have been bowled out in their first innings in less than 40 overs.
It is the second time this summer that both sides have been dismissed in their first innings in less than 45 overs, the first being the first Test against New Zealand.
Prior to that is had only happened once in a Test in England and five times in a Test anywhere.
Vic Marks
Former England spinner on BBC Test Match Special
It is a fragile and unbalanced England batting line-up. So much rests on the big players, which now includes Ollie Pope.
A lot hinges on Joe Root but he has had a pretty lean period in this South Africa series.
That is quite a remarkable statistic.
I would imagine we will see quite a different approach from South Africa with the bat today. Surely, their aim is to just bat for the rest of the day. But the pitch has been very favourable to the bowlers, so it's going to be a difficult task.
We are in for an interesting day of Test cricket - again.

Both innings lasted 36.2 overs. If this was a 'normal' Test, South Africa's second innings would be starting about an hour after tea on day one.

Four runs. Thirteen minutes. Three wickets.
It's good for the game, but not good for England. At a minimum you thought they should have got a lead of at least 100.
South Africa are back in the game, though they have got some batting to do.
Foakes c Petersen b Jansen 14 (Eng 158 all out)
Marco Jansen gets it! Ben Foakes prods outside off stump and the ball flies off the edge to the slips where Keegan Petersen takes a smart low catch.
Jansen raises the ball to the crowd as he leads South Africa off the pitch. It's been a fine bowling performance from him.
England are all out for 158 with a lead of just 40. Could this Test be over in two days?
Lead by 40
Kagiso Rabada and Marco Jansen have four wickets each now, but Jansen has bowled significantly better. Who will get the five-for first?
