South Africa have their tails up too. Khaya Zondo plays a lovely straight drive of Ben Stokes' final delivery of the over and the ball disappears over the rope for another four.
Wow, what a ball from Ben Stokes. He gets one to wildly swing away from Khaya Zondo, squaring him up and narrowly missing the outside edge.
England suddenly have their tails up.
That's a great shot from Khaya Zondo.
It is short and wide from Ben Stokes but still had to be put away, with Zondo playing a lovely cut that flies over backward point for four.

Robinson hadn't swung the ball and looked the least likely of the four seamers to get a wicket but that's a big one for England. Their patience has paid off now, the game situation hasn't changed.

Bowled him! England wanted that! A sorrowful-looking Mulder is on his way.
Mulder b Robinson 14 (SA 120-5)
Played on!
Relief for England as Wiaan Mulder attempts a shot off the back foot but the ball hits the inside edge, cannons into his pads and onto the stumps.
Ollie Robinson lets out a huge roar of delight and then stares at Mulder as he makes his way off the field.

We can conclude that Joe Root has had a very good afternoon in terms of ball polishing but not a very good one when it comes to ball watching.
Oh dear. There's audible groans from the crowd as ultra edge shows nothing. England have now used up all their reviews.
Joe Root cannot believe it, he was certain Khaya Zondo had got something on it.
Now then. The England slip cordon is certain Khaya Zondo has feathered the ball through to Ben Foakes as he pulled out of a shot.
Ben Stokes was not initially convinced, but he has gone for the review anyway.
A poor ball from Ben Stokes as he strays down leg and Wiaan Mulder can clip the ball fine for four.
Lead by 71
A bit of fire from Ollie Robinson as he fields a Wiaan Mulder drive off his own bowling before hurling the ball back at Mulder's stumps.
These two batters may start to feel that they have negotiated a tricky afternoon spell.
The atmosphere has flattened a bit after that flurry of excitement from Broad and Anderson.
The ball is approaching the 40 over mark, too, which is usually the signal for batting to get easier.
A brilliant ball to end the over from Ollie Robinson as he gets one to jag back into Khaya Zondo and the ball fizzes just over leg stump.
A boundary! The first for 12 overs and one ball.
It is a good shot from Khaya Zondo too as he cuts a short ball from Ollie Robinson through the off side.
Will this signal a change in approach?
A brilliant over from Ben Stokes as he gives Wiaan Mulder a thorough working over.
Mulder does well to dig out an inswinging yorker before Stokes beats the outside edge with a viscous outswinger.
Stokes has a rueful smile as he collects his cap from the umpire.

The game is on the cusp - I'm enjoying it. England lost the initiative dramatically in that first session but have regained it. There's not a lot of strokeplay out there at the moment but it's brilliantly poised.
There's plenty of gasps from the crowd as a peach of a delivery from Ollie Robinson fizzes past the outside edge of Khaya Zondo's bat.
Robinson bang on the money first up.

That's the first time he's done anything extravagant - it was a horrible heave.
Lead by 62
A rather dramatic gear change from Khaya Zondo as he attempts a huge heave off Ollie Robinson's first delivery but completely misses it and the ball flies through to Ben Foakes.
Where did that come from?
In fact, here he is now.
