That ball was a bit loose and Shabnim Ismail just needs to settle.

The three fastest balls recorded in women's cricket have been bowled by Shabnim Ismail.
Pacer and England's nemesis Shabnim Ismail is into the attack. She starts with a dot.
Next ball though is cut away for four.
Some fans have been getting creative in the last couple of days.
Three more dots and a single, a good recovery from Mlaba.
It's funny, there's no noise as the bowler goes through her action, everything is so tense. And then there's a cheer of relief each time Australia fail to add to their score.
And now a first boundary as Healy sweeps one to the ropes.
Silence in Newlands.
Nonkululeko Mlaba bowls the first ball of the World Cup final. Alyssa Healy blocks it for a dot. Huge cheers.

Our national anthem is a compilation of four languages and in that moment we all came together. We have already won.
The players are all set in the field now. We're so nearly there!

Well, that was quite something!
You could see the South Africa players barely able to sing the anthem because of the emotion, but the crowd certainly made up for it.
A special, special occasion.
Alex Hartley
Former England bowler on BBC Test Match Special
Incredibly special. Kapp was in floods of tears not even able to sing the anthem.
What a day this will be because it's already started amazing.
What a noise! The anthems are done, there were tears among the South Africa line-up as the cameras panned past.
This is a very special atmosphere.

I think South Africa might be better off chasing knowing what they need to do. This is a very special team because we've got women from all race and class groups. If South Africa manage to do the impossible, it will be so huge for the country.

Former England bowler on BBC Test Match Special
It's going to be tough. Can South Africa beat the unbeatable? Australia are firm favourites but so were England. Anything can happen in finals. Whatever happens today is a win for South Africa because they have sold out Newlands.
The players are walking out...

Rugby World Cup winning captain Siya Kolisi is an ambassador for the Women's T20 World Cup and after watching South Africa reach the final on Friday, he's back in the stands today - and Newlands just erupted as he led some young children out on the pitch for the closing ceremony.
It's got the feeling here of a really historic day. It is packed, almost full already, and what's most heart-warming is just how many young boys and girls are here to enjoy the occasion.
During the warm-ups, you could see the South Africans waving to the crowd, taking it all in, making the most of the occasion. But the Aussies, as ever, looked like they were blocking it all out and just focusing on getting the job done.

Australia have faced South Africa six times in T20 World Cup matches. They've won all six.

Friday's semi-final was disappointing for England but it was an absolute joy to see the reaction from South Africa, both their players and their fans.
Sune Luus said in her news conference yesterday that she never thought she'd see people queuing outside Newlands for tickets to a women's cricket match, but today they've managed to sell it out, and that is history in itself.
As we were driving in earlier this afternoon, fans were already lining the streets in their green and yellow shirts, flags waving, children cheering.
South Africa proved against England that they are a dangerous side when they're the underdogs and in a way, they've already won by making it this far.
