SA 15-0published at 4.1 overs
Woah, South Africa get a leg bye despite Wolvaardt not offering a shot.
That should be a dead ball. Will that one single end up costing England? Let's hope not!

Brits 8, Wolvaardt 4
Another tidy over with just five from it. South Africa have just 12 balls left of the powerplay as spinner Charlie Dean comes into the attack.

That was a terrifically executed sweep.
There's the noise from the crowd! Brits gets low and sweeps Ecclestone to the leg-side boundary.
South Africa needed that. Next ball Ecclestone just beats Brits' outside edge. What a battle!
And now England bring in world number one bowler Sophie Ecclestone. How will South Africa handle spin?
Two more dots.

Heather Knight is blessed with a lot of options in the powerplay. We often see the sixth over is the most important. Katherine Sciver-Brunt may be saved for that.

How that has missed I do not know.
So close!
Laura Wolvaardt swings and misses as a rapid delivery only just misses leg stump. Great stop by keeper Amy Jones too.
South Africa get a precious run as Brits hooks one to deep fine leg with a nervous pull shot. England will be loving this slow start.
Katherine Sciver-Brunt continues. She starts with three dots as England bring on the squeeze.

South Africa only have one batter that can take the ball away from you. That is Chloe Tryon. These two have been accumulators.

I was gutted when Dane van Niekerk missed out on selection. But now, as we start to bowl at them, I am much happier. She'll be a big miss for them today.

It might be worth all cricketers having extra long fingernails.
Half a chance again for England as batter Brits drives the ball straight against the non-striker's stumps. Did England bowler Lauren Bell get a fingernail to the ball with Wolvaardt out of her crease? Nope, no luck.
Haha love it Jack! Let us know how you're watching via the usual methods please.

Brits 2, Wolvaardt 4
Shot! Tazmin Brits drives Lauren Bell through the off side for two. England have a slip in.
Next ball and there's the swing we're used to with Bell as the ball squirts into Brits' pads. Huge appeal from the bowler but the umpire shakes their head.
And that's the over, just the boundary from it. England look pumped for this.

It is a risky field from England. Katherine Sciver-Brunt shapes the ball away and Laura Wolvaardt likes to cut.
Second ball, first boundary. Not great from Katherine Sciver-Brunt who fires one in short and wide which is brilliantly dispatched by Wolvaardt to the fence.
Sciver-Brunt responds with two dots.
