Target 182
Don't switch off just yet.
Mosehle whacks David Willey for six to start the 15th over.
SA 93-6published at 14 overs
89 to win from 36 balls
He gets plenty of stick on this page but Chris Jordan has 3-14 from three overs though.
He's now England's fourth highest wicket-taker in T20 cricket. He's got a long way to go to catch Stuart Broad at the top of the list though.

James Taylor
Ex-England batsman on BBC Test Match SpecialI'm enjoying the way England have bowled. It's not their first-string bowling line-up but anyone who has come into the side has delivered. The seamers, in particular, have nailed their yorkers and variations.

Ex-England batter on BBC Test Match SpecialIt's not looking great for one South African team - but at least their women's team have somehow won against Pakistan.

Behardien c Billings b Jordan 3 (SA 91-6)
Catching practice!
Short, pull, catch, repeat.
Great bowling from England but poor batting from South Africa. Another pull shot skied and England are closing in.

Dan Gee: Brilliant by Mason Crane. Kept throwing it up and got his reward.

Ex-England batter on BBC Test Match SpecialThat was an incredible over but also some of the worst batting I've seen for a long time: swipe, swipe, swipe and more swipes!

Crane 1-38
Mason Crane is getting out all of his tricks. Behardien doesn't have a clue he has been bowled a googly as he swings and misses.
Three more times Crane beats the bat. A quite brilliant over.
I reckon England have got themselves a good 'un.
Crane gets a great reception as he finishes his final over.

"Catch! Oooooooooo".
The crowd are well into this as Mangaliso Mosehle almost offers a catch on his first ball.
Good from Jordan. Just four from the over. He doesn't let Mosehle get off the mark.

Miller c Buttler b Jordan 7 (SA 86-5)
Miller gone! England are running away with it!
Chris Jordan has got two wickets with two rank deliveries but won't care.
Short and wide and Miller throws the kitchen sink but can only edge through to Buttler who takes a good catch.

Pressure on David Miller and Farhaan Behardien now. South Africa need a partnership after two quick wickets.
Here's the first of them. JJ Smuts caught by Dawid Malan off Liam Plunkett.

De Villiers c Hales b Crane 35 (SA 82-4)
What a wicket for Mason Crane! He's got AB de Villiers for his first international wicket!
De Villiers looks to go again and is caught on the boundary by Hales.
Brilliant from Crane. He'd been hit for two sixes but still threw it up there. And a great celebration. The 20-year-old punches the air and wheels away. He looks delighted.

And again! De Villiers is motoring. Same shot, same result.
Six more.

Ex-England batter on BBC Test Match SpecialThis is a challenge for Mason Crane now. He doesn't look to have an answer to AB who is just swinging through the line.
SA 74-3published at 10.2 overs
Is AB de Villiers going to target young Crane here?
He sweeps the spinner for four off the first ball and then launches a six over mid-wicket a ball later with the same shot.
That flew off the bat.

Target 182
A wicket and five singles. Excellent over from Plunkett.
England will be happy with this won't they? We're at the halfway stage and South Africa need 118 runs to win.
