How would I decide it if teams finish on level points? Five-a-side football?

South Africa have got off to a decent start. England are used to picking up wickets in the powerplay but they've only managed one. Evenly poised.

Jonny Bairstow has run in from the boundary to have a word with Rassie van der Dussen - it looks like he is accusing him of running on the pitch.

Meanwhile, Quinton de Kock looks to step things up with another reverse sweep past third man for four. Eight off the over.

South Africa reach 73-1 at the halfway stage. A decent platform.

If you just bat 3 metres down the track then you can't be out?

Ooh, it's umpires call on the impact as it's more than three metres down the pitch.

Morgan can't believe it.

Van der Dussen this time doesn't look so calm.

Chris Jordan thinks he has trapped Van der Dussen lbw. It's a huge appeal but the umpire says no.

England send it upstairs.

Chris Jordan is now into the attack.

This was the first six of the innings from Rassie van der Dussen.

South Africa need more of those and quick if they are to get the hefty total they need.

That's Jos Buttler who's got that one wrong.

Nothing on Ultra edge.

Whatever Jos Buttler heard, it wasn't bat on ball.

That was a bit of a swipe from Van der Dussen.

Jos Buttler thinks he has snared Rassie van der Dussen behind the stumps.

The umpire says no, but England review.

Moeen Ali ends with 1-27 from four overs.

Adil Rashid is into the attack.

That is the second time in this tournament that Moeen has bowled four overs opening the bowling. Before that, no England bowler had done that since Stuart Broad in 2006.

Here is the first wicket to fall as Moeen Ali bowls Reeza Hendricks for two.

Great shot from Quinton de Kock as he plays a reverse sweep through deep fine leg for four. Brilliant technique. De Kock is looking in good touch so far.
