SA 162-7
A fine bowling performance from England.
For a while South Africa threatened but in the end, wickets at crucial times did for the visitors.
England win the series 2-1.
24 to win from one ball
Just a single.
24 needed from one ball.
Good luck South Africa...
Target 182
Another four to Phehlukwayo, this time smashed down the ground.
This will do nothing but damage Chris Jordan's figures the game is done.
Poor from the England man. He bowls a no ball on height and gives away a free hit.
32 from four to win
Four to Phehlukwayo who is joined by Morkel at the crease.
He bravely gets low and sweeps Jordan.
Too little too late.

Even in the Champions Trophy, England managed to take wickets throughout the innings. That's been the difference in this game. England managed batting partnerships but South Africa haven't been able to do that.
Mosehle c Billings b Curran 36 (SA 145-7)
That should be that!
Mosehle tries to go big on a full toss from Curran but can only spoon it up for another catch in the deep.
The umpires have a look for a no ball but no, that's fine, and Curran has a second.
Target 182
Maybe it is not all over. Four to Mosehle.
Target 182
Excellent from Curran.
I feel like I am repeating myself but it really is. Slower ball and Phehlukwayo can't get it away.
England are closing it out.
Target 182
Tom Curran starts the 19th over with a dot followed by a leg bye. This is the over for South Africa.
Got to go to give yourselves a chance in the final over.

It would be miraculous if South Africa were to win this. England would need to have a complete meltdown.
Target 182
Phehlukwayo is trying to swing free but not quite timing it like Mosehle.
Better finish from Willey. A ball in the block hole and the batsman can do nothing.
A Mexican wave goes around the Cardiff crowd. They think this is done.
44 from 12 to win for South Africa.
Target 182
David Willey is the odd man out in this England attack today. He's getting the treatment.
Mosehle flat bats him for six and then follows up with an even bigger maximum that goes out of the ground and I suspect into the River Taff.
New balls please*.
*It's nearly Wimbledon so thought I'd throw this in there, apologies.

Both of the Curran brothers invest a lot of time in their looks and appearance. There's a lot of product in their wash bags.
Surrey, in general, are like that. We used to call them the Surrey Strutters.
Target 182
Four dots in the over. Excellent from Tom Curran. He gets a big clap from Paul Farbrace.
Fully deserved.
61 to win from 20 balls
Tom Curran started this excellent bowling performance with the early wicket and is now back into the attack.
Three dots to start. Perfect. Fourth ball. Not so perfect. Six over fine leg.
Caught in the crowd. Well done, sir.
Target 182
Plunkett finishes off the over well. He's been brilliant. Three overs one wicket for 22 from his four.
Could 11th over be the one that wins it for England? Mason Crane started it by conceding two sixes to AB de Villiers but ended it by dismissing the South African for his maiden international wicket.
In the words of Barry Davies, "just look at his face".
De Villiers launches for six

Adam Wheeler: Buttler showing again that his captaining credentials are good.
Target 182
Mason Crane is beaming on the boundary as his wicket celebration is played on the big screen. He's dismissed AB de Villiers for his maiden international. He's allowed a smile.
Liam Plunkett back into into the attack. He nearly knocks Phehlukwayo head off with a bouncer first up and then the batsman tries a clever scoop but only gets a single.
Good start to the over.
Charles Dagnall

Phehlukwayo pummels the ball. He looks like the type of player who can knock a ball out of shape.
Target 182
Four again!
An excellent over for South Africa but they need that every time.
Five overs to go. 71 needed.
