Ecclestone (6-36) takes first international five-wicket haul
Shrubsole takes two wickets with new ball
England post 293-8 after being asked to bat first
Wyatt - dropped five times - makes 129 off 125 balls
Opener shares stand of 116 with Dunkley (60) for fifth wicket
Klaas c Beaumont b Ecclestone 3 (SA 152-9)
A maiden international five-for for Sophie Ecclestone! And thoroughly deserved!
Klaas tries to swing the ball over the leg-side but instead sends a leading edge into the off-side where Tammy Beaumont takes a simple catch at backward point.
Ecclestone enjoyed that!

England are well on top, you can tell from all the smiles out there.
It's been a great tournament but the semi-finals have probably been the worst two games!
Klaas 3, Chetty 17
That is Charlie Dean done for the day, she finishes with 1-41 from her 10 overs. Another good day for her.

Target 294
Ecclestone quite believe she hasn't found the edge with two rippers to end the over. Far too good for Masabata Klaas, in at number 10 for South Africa.

Ecclestone is nudging very close to becoming Player of the Tournament.

Sophie Ecclestone wins the battle and England take another step closer.
Ismail c Dean b Ecclestone 12 (SA 148-8)
Make that four for Sophie Ecclestone. Shabnim Ismail advances once more, tries to hit over the top but didn't time it at all and Charlie Dean takes the tumbling catch at mid-off.
One more for the five-for, two more to seal the win.
Target 294
Ismail helps herself to four more after a misfield at cover - another powerful stroke but it should have been stopped.
Very nearly a caught and bowled for Dean next ball, a leading edge looping up but it's just out of reach of the bowler as she dives forward. And now a missed stumping! Ismail down the pitch again, misses but there is something on it that deceives Amy Jones and ball runs away for four leg byes.

An England-Australia final is probably what this tournament deserves.
The game might be up but if there is one person who refuses to believe this is over, it would probably be Shabnim Ismail! She comes skipping down to Ecclestone and thumps the ball through the covers for four.
On we go.
Sophie Ecclestone will continue. She has three wickets to her name in this semi-final, the first of them a beauty to bowl Marizanne Kapp...

How different might this game look had South Africa held on to those chances off Danni Wyatt?
Target 294
Charlie Dean has been very impressive again, the young off-spinner has 1-29 from eight overs with just three coming from her latest.

Image source, Getty ImagesThe scary thing for Sophie Ecclestone is that she's only 22. She's already the best in the world in both white-ball formats, she's just got the most wickets ever for England in a World Cup.
Where can she go next?
SA 125-7
In theory, we still have 18 overs left in the game but England will want this wrapped up much more quickly.
South Africa need more than nine an over from here. I'm not sure that is really a consideration anymore, though.

That Ecclestone has never taken an international five-for remains one of the more unbelievable statistics given her record over the years.
She has a chance to put that right at the Hagley Oval, no wickets in this over but she has another five to try and take the two wickets she needs.

Sophie Ecclestone will be thinking of the five-for.
Target 294
Decent over for South Africa with a pair of twos for Chetty as well as a couple of leg-side wides, Dean getting good turn but from too straight a line.
