Heather Knight drills it through the covers for another boundary.

Fifteen from the over. Knight is on 57 off 44 balls.

It has been difficult for Ayabonga Khaka since Shabnim Ismail's come back. Khaka was used to sharing the new ball. She doesn't do that at all, and now she has to bowl at the death.

There's no stopping that. Heather Knight brings up her half-century in style with a six to the leg-side boundary. Fantastic.

Both Shabnim Ismail and Marizanne Kapp have completed their allocated overs.

Ayabonga Khaka - who has been expensive so far - is brought on. Some good fielding on the mid-wicket boundary prevents the four.

Heather Knight swats it back past the bowler for four. She put everything into that.

The England batter swipes across the line and it falls short of Nadine de Klerk who runs in from deep mid-wicket.

I think Chloe Tryon was calling for it as she looked irritated that Sune Luus blindsided her.

This World Cup has seen more fours per match than any previous edition of the tournament.

There have been an average of 30 boundary fours per match so far, beating the previous record of 27 per match at the 2023 T20 World Cup in South Africa.

Heather Knight chips it back past the bowler. It's high. Sune Luus and Chloe Tryon both sprint towards it but it falls between the two fielders.

Knight runs one. Nat Sciver-Brunt lofts it into the leg side for another single.

Terry: Pure class from Sciver-Brunt. Perfect platform for 200 now.

A decent over by Nonkululeko Mlaba - who has struggled with her line today. Just three runs off it.

South Africa like chasing, it is how they beat India 4-1 in the series back home before this tournament. It is where they feel they can control the pace of the match when they're chasing.

After a short drink breaks, Nonkululeko Mlaba continues. You can see from the South Africa body language how desperate they are for a breakthrough.

Seb: Nat Sciver-Brunt is the female equivalent of Ben Stokes. She is here, there and everywhere and knows when to turn it on in big occasions.

There are people standing around The Oval to applaud Nat Sciver-Brunt's fifty. She holds her bat in the air like a warrior. One leg or not. Some knock.

Nat Sciver-Brunt has played so well. This is why England did everything to get her back on the park. To have the captain back, and she is leading from the front again.

The way Nat Sciver-Brunt executes the ramp shot is something else. Up and over the wicketkeeper for four.

And then she brings up her half-century with a sublime drive through the off side for another boundary.

She's on 53 off 35.

Horrible appeal from Nadine de Klerk. Heather Knight is so far outside off stump when she's struck low on the front pad.

A full toss is given the treatment it deserves as Nat Sciver-Brunt sweeps for four.

Charles: Harry Kane last night, Nat Sciver-Brunt and Heather Knight tonight. The old guard to England’s rescue.
