David: Oh no! Dunkley out first ball. A shame for the BBC viewers who might not have seen her, especially with her recent form. Gives Alice Capsey an early chance so hope she can impress.

That's what I love about her. The team are under pressure and lost an early wicket. But she's not afraid to play her shots.
Alice Capsey takes a couple of steps down the pitch and flat bats Masabata Klaas back over her head for four.
If that was brutal from Capsey, her next shot is pure timing. On the back foot she cuts Klaa aerially s to the boundary for four.

Alice Capsey is not frightened to take bowlers on. She's young and aggressive. England have been after a player like this for a long time.
Sophia Dunkley's dismissal brings 17-year-old Alice Capsey to the crease for her first opportunity with the bat in international cricket.
She's off the mark with a neat slog sweep.

Not a great start. It wasn't the best delivery. It was short and wide. A disaster of a start for England.

Absolute delight for Mlaba. Sophia Dunkley has been the form player for England. That is an enormous blow.
Dunkley c Wolvaardt b Mlaba 0 (Eng 0-1)
Sophia Dunkley gone first ball!
South Africa start with spinner Nonkululeko Mlaba and Dunkley cuts a delivery tossed up outside off stump straight into the hands of Laura Wolvaardt at backward point.
Mlaba roars with delight. Dunkley trudges back to the dug out.
South Africa's fielders are just jogging out to the middle. Danni Wyatt and Sophia Dunkley will open the batting for England.
We'll be underway shortly.
South Africa batter Laura Wolvaardt: "I'm quite experienced for how young I am so it is a good position to be in. There aren't that many 23-year-olds who have played as many games as I have so I am a bit of a senior player game-wise and I'm really enjoying the challenge.
"Coming into the series I was a bit one-dimensional. I had my cover drive but I wanted to add a few more options, especially in in T20s. I want to improve my power game and use my technique to hit big shots and big sixes. I'm getting there but it is still a work in progress."

England have worked really hard on their batting and it has been brilliant to see different players stepping up when needed throughout this series.
South Africa captain Chloe Tryon, standing in for the injured Sune Luus: "We would have had a bowl as well. It’s a good opportunity to bowl, restrict them and assess the conditions as quick as possible.
"Unfortunately Sune fell ill last night and is under the weather. It’s not my first rodeo – I’ve been here a couple of times. We’re keen to finish the series on a high."

Alice Capsey brings all-round ability. She can bat anywhere, from three down to seven. She has a golden arm and can pick up wickets. She has a real swagger about her.
England stand-in captain Nat Sciver: "After bowling first in the previous two games we thought we would have a bat this time.
"Heather Knight is doing well. She never likes being off the pitch - whether it's training or matches. She's not quite ready for this evening. Hopefully she will be ready for the Commonwealth Games.
On Freya Kemp's debut: "She's a left-armer and is an exciting talent. Also Alice Capsey, who did not not bat the other night, will get a chance to show what we she can do if we lose a wicket in the power play."
Freya Kemp is into the team in place of Bryony Smith while pace bowler Issy Wong returns ahead for Freya Davies.

England are in a really good place. We've seen some new faces. New seam attack. New batting line-up. It's exciting.

Freya Kemp is a hugely exciting cricketer. I had the pleasure of working and playing with her this year. I don't want to big her up too much, but she's as good a 17-year-old cricketer I can remember seeing. She bats, she bowls, she's athletic - she's got it all.
