Joanne Broadbent
Ex-Australia batter on BBC Test Match Special
I'm going for Stafanie Taylor. I think England need to score over 130 to win.

I am going to go for Tammy Beaumont for my player of the game. She's got a point to prove back at opener.
I think England need 145 to be confident of winning.
Plenty of support in the stands - one England couple have even gone with the cross of St George daubed across each cheek.
There's almost a comedy moment when the players walk off post-anthems - West Indies' Hayley Matthews nearly trips over the rope.
If you and your children have been inspired by following this tournament, the England and Wales Cricket Board has launched a new programme called Dynamos Cricket to inspire kids aged 8-11 to play the sport.
The new scheme aims to build on the exisiting All Stars programme for 5-8-year-olds.
Two programmes in May and July will allow up to 35,000 more children to play cricket this season.
Participants will get to work on their batting, bowling and fielding as well as playing in games of countdown cricket – a new format that mirrors The Hundred.

The stirring sound of "Rally Round The West Indies" precedes the more formal "God Save The Queen".
Here are the teams:
England: Amy Jones (wk), Danni Wyatt, Natalie Sciver, Heather Knight (capt), Fran Wilson, Tammy Beaumont, Katherine Brunt, Anya Shrubsole, Mady Villiers, Sophie Ecclestone, Sarah Glenn.
West Indies: Stafanie Taylor (capt), Deandra Dottin, Hayley Matthews, Chedean Nation, Leeann Kirby, Shemaine Campbelle (wk), Shakera Selman, Britney Cooper, Afy Fletcher, Aaliyah Alleyne, Anisa Mohammed.
As for West Indies' batting order, with the changes they've made, your guess is as good as mine when it comes to their batting order.
Teams coming out for the anthems.

I think we know why Heather Knight was being a bit eggy there at the toss. Tammy Beaumont has her pads on and it looks like Amy Jones will drop down the order.
We're also hearing that West Indies might open with Deandra Dottin and Stafanie Taylor.

Tammy Beaumont is walking around the boundary rope with her pads on...

She's done something on the boundary rope. She's been taken off on the stretcher. I've messaged her but obviously not heard back yet as she's not got her phone with her.
(ICC anti-corruption regulations force players to hand over their phones before games - they only get them back after the close of play)
Henry Moeran
BBC Test Match Special
Worrying sight for England as the team doctor rushes on pre-game. It looks as though Kate Cross - not playing in this game but going through some bowling drills - has injured her right leg. She's carried off the field on the back of a buggy, looking in considerable discomfort.
We're hearing that an England player has been stretchered off after being injured in the warm-up.
It's Kate Cross, who's in the squad but hasn't played in the tournament so far. Our best wishes to her.

Test Match Special have reclaimed the airwaves on BBC Radio 5 Live Sports Extra - you can also listen via the audio icon at the top of this page.
Henry Moeran, Andrew Moore, Alex Hartley and Joanne Broadbent are standing by at the Sydney Showground to talk you through England v West Indies.
While we wait, here are the full highlights from South Africa's win over Pakistan:
And we can also point you towards Heather Knight's latest BBC Sport column as she marks that 10-year anniversary:
"I can't believe it's been 10 years since I made my England debut - it makes me feel old!
"I made my debut with Danni Wyatt in an ODI in India at the Bandra Kurla Complex in Mumbai.
"There was probably one person there, and I think it was a parent! No-one really took notice of what was going on.
"It is mad to think how far things have come since then."
You've heard of the 10-year challenge?
England captain, leading tournament run-scorer and BBC Sport columnist (since 2014), Heather Knight today celebrates 10 years since her international debut.
Our challenge to you is... how many of her 10 team-mates from that day, 1 March 2010, can you name, if we give you a few sneaky clues?
You can try the quiz here via the BBC Sport website and app.
West Indies captain Stafanie Taylor:"We have nothing to lose today. We have Britney Cooper and Aaliyah Alleyne in, with Chinelle Henry and Shamilia Connell out."
This is how West Indies have fared so far - beating Thailand but then losing to Pakistan.
Well, we'll see in about 20 minutes who's opening for England...
England captain Heather Knight: "The pitch looks a bit slow, so hopefully we can put a decent score on the board and defend it.
"It looks like the wickets we played on in Malaysia. We've got confidence in our bowling unit to defend any score.
"You'll have to wait and see who we open with.
"We have one change - Mady Villiers comes in for Lauren Winfield because we wanted another spin option on this pitch."
England have won the toss and will bat.
They make one change - with Mady Villiers replacing Lauren Winfield.
But will there be a change at the top of the order?
