How does Kapp play this now? Without her, South Africa crumble. But to get anywhere close, and to finish the game with some pride, she has to play some shots.

BBC Test Match SpecialIt's a fairly muted celebration because it has been in what is probably a hopeless cause in terms of the match. But she has shown some resistance here.

SA 195-4
South Africa's rock helps herself to yet another half-century.
She dinks one into the off side to reach the milestone, but the expression on her face says she's not done yet.
What would South Africa have done without her this series?

England all-rounder on BBC Test Match SpecialIt's been one of those days for Kate Cross, the ball has just evaded the fielders at all times. She's looking on in despair, it's not the worst ball and it's heaved away for four by Tryon.
SA 191-4published at 31 overs
A slower ball from Kate Cross is pumped through the leg side by Chloe Tryon.
They have got a long way to go but they haven't given up yet. Great fight.

The umpires send a stumping review upstairs but Tryon is comfortably back in her crease.
A good response from Bell, beating the batter outside the off stump, and excellent work from Amy Jones standing up to her pace.

England all-rounder on BBC Test Match SpecialWith the field set as it is, with mid-on and mid-off up, that is basically a free hit for Chloe Tryon.

Ooooft, here we go!
Chloe Tryon launches Lauren Bell back over her head and into the stands for six! She really does give it a whack.

England all-rounder on BBC Test Match SpecialMarizanne Kapp is just hitting to hit everything as hard as she can. There wasn't that much width on that ball, but it was just maybe a bit short and that's what made for the boundary.

Kapp 44, Tryon 20
The same shot and the same result.
Another expensive over from Cross, who hasn't found her rhythm today.
SA 167-4published at 28.1 overs
Runs are flowing!
Kate Cross comes back into the attack and Kapp welcomes her with a slash past point for four.

Anya Shrubsole
Former England bowler on BBC Test Match SpecialThat should really be taken by Lauren Bell. Chloe Tryon couldn't have picked her out better if she tried. She barely had to move but it just went straight through her hands.

SA 163-4
Ohhh.
The short ball from Issy Wong nearly accounts for Chloe Tryon again. She pulls one straight to Lauren Bell down at fine leg but it slips through her hands and over the ropes for six!
I wonder if the sun was distracting her. Still should have been taken.

Alice Davidson-Richards joined Emma Lamb in taking her maiden ODI wicket, with a bit of help from Lauren Bell.

Southern Vipers batter on BBC Test Match SpecialIt is the fact that South Africa have lost four wickets, it means there is a lot of pressure on these two.
SA 157-4published at 27 overs
Oh, lovely.
Davidson-Richards bowls a slower ball but Kapp waits perfectly for it and thrashes it through the covers for another four.
11 from the over, which is just above the rate they need to keep going at.

BBC Test Match Special statisticianAt the drinks South Africa were 146-4 after 26 overs. At the same point were England 178-1.
Obviously there's no chance of rain at the moment but the DLS score at that point was 215.
