Fourth Test, day two, Johannesburg
England lead 2-1 in four-Test series
Curran c De Kock b Nortje 0 (Eng 269-7)
First ball! What are you doing, Sam Curran?
That is a dreadful shot first up. It was full and even wider than the Root wicket and Curran just wafts his bat lazily. There's a thick edge and it is snuffled behind the stumps. Nortje is delighted. The crowd is alive. Suddenly South Africa are right back in it.

I'm not sure the wicket has opened the door hugely for South Africa, they've got enough batting to get a good score.
But Root has missed out on a chance to cement this Test for England.
Jonathan Agnew
BBC cricket correspondent in Johannesburg
That was a rather casual drive outside the off stump. Root is absolutely furious as he walks off.
This game is alive.
Root c De Kock b Nortje 59 (Eng 269-6)
Joe Root is out this time! He will not make South Africa pay for the dropped catch and it looks like he has not learnt. The dismissal is almost identical to how he should have been out when he was dropped - driving and edging a full ball from Nortje. This time Quinton de Kock safely takes the catch. Relief for Faf du Plessis.

It looks like one extra security guard positioned at the tunnel entrance today where Ben Stokes got involved in his altercation yesterday. There are also perhaps a few more stewards about. But I wouldn’t say there is evidence that security has been significantly enhanced today. England reported not just Ben Stokes, but also backroom staff were subjected to personal abuse during and after play yesterday.

It looks like Faf almost had too much time. He was trying to take the catch while shimmying to his right.

That would have been a big wicket with the new ball due in eight overs time.

His eyes weren't level. He's a good catcher normally, I'm very surprised. Maybe he was just thinking of a bowling change or something.
A big, big drop from South Africa skipper Faf du Plessis. He has put down his opposite number Joe Root at slip.
You're not going to get many easier catchers at slip. It was just to his right at a good height after Root edged a drive.
Nortje should have two in as many overs.

Jos knows, and will have thought a lot about, the fact that he needs to score runs. He's been crying out for England to have these starts so he can come in and play his way.
He needs to just play as instinctively as he can.
Root 53, Buttler 4
Jos Buttler has Dwaine Pretorius to face now who is just finding a little bit of movement around 75mph with his seamers.
Buttler is much more watchful in letting the ball go by outside off.

Literally the first ball I listen to in this match... wicket. Radio safely turned off now I promise.
Laura
Is this a sign of how Buttler is going to play under pressure or just punishment of a bad ball?
The fourth ball he receives is very wide from Nortje and Buttler crunches it for four.

England still way ahead of the game but with Jos Buttler coming in now, this is a big moment for him and his Test career.
A lot of wicketkeepers will be watching on eagerly, both in South Africa and at home in England.
Here's Jos Buttler who Paul Farbrace said earlier is playing for his Test career.

It's a huge wicket. You have a break, have a drink and then just switch off for a second. It's a horrible dismissal, probably one of the worst ways you can get out.

First ball after drinks! Ollie Pope has to drag himself from the middle. He wanted so many more. Was he not quite back in the zone after the break in play?
Pope tries to leave a full ball from Nortje but is a little late in doing so and gets an inside edge onto his stumps as he pulls the bat away.
There's a big, angry punch of the air from Nortje. South Africa needed that.

They've scored 66 runs in 14.4 overs.
