Ooh, that was close. A slower ball from Megan Schutt tempts Sophie Devine into trying a huge heave that she completely misses, but the ball just misses the stumps, flashes past wicketkeeper Beth Mooney and away for four byes.

Sophie Devine is strong through the leg-side in the power play so Megan Schutt persists with a line outside the off stump. Devine gets off the mark with a nudge into the off-side for a single.

Sophie Molineux then drives her first ball towards the point boundary, but some smart fielding cuts the ball off and they run two.

A good start from Schutt, who will continue with the next five.

Lord's, as ever, looks an absolute picture as the London Spirit players make their way onto the field.

Birmingham Phoenix openers Sophie Devine and Sophie Molineux, who has been promoted up the order, soon follow.

Megan Schutt will open the bowling for Spirit.

Here we go...

Birmingham Phoenix: Sophie Devine (C), Eve Jones, Amy Jones (WK), Ellyse Perry, Sophie Molineux, Georgia Elwiss, Gwen Davies, Issy Wong, Emily Arlott, Kirstie Gordon, Ria Fackrell.

London Spirit: Beth Mooney (WK), Dani Gibson, Sophie Luff, Amelia Kerr, Charlie Dean (C), Naomi Dattani, Alice Monaghan, Grace Scrivens, Nancy Harman, Freya Davies, Megan Schutt.

Today's match-up sees one of the game's most experienced international players up against a rising star.

England's Charlie Dean has been entrusted with London Spirit's captaincy at the age of just 21. Like her team Dean has yet to reach the heights we know she can during this tournament, but can she end on a high?

In contrast, Birmingham Phoenix captain Sophie Devine has been there and done it having made more than 200 white ball appearances for New Zealand, who she has captained since 2020. The 32-year-old also led Perth Scorchers to success in the Women's Big Bash last winter.

Known for her destructive batting, Devine has scored 94 runs from 58 balls so far this tournament and also has two wickets to her name.

Birmingham Phoenix, Trent Rockets, Manchester Originals and Northern Superchargers can all still join Southern Brave and Oval Invincibles in securing a place in the knockout stages.

The Rockets beat seventh-placed Welsh Fire on Monday to move into third place and put the pressure on Phoenix ahead of their game against Spirit.

Phoenix's fate remains in their own hands though, with a win or tie seeing them climb back above Rockets and be guaranteed of a place in the play-offs.

Birmingham Phoenix captain Sophie Devine: "We would have batted so it's worked out well for us all!

"It's been the case for the last two or three games that if we win, we go through! But it's a great opportunity and there aren't many better places to play in the world than this.

"We've just got to keep being positive. Sometimes you can get into a bit of a hole and that's when you go into your shell but I want to see us keep taking the game on, so we want to get back to that cricket we were playing at the start of the tournament."

London Spirit captain Charlie Dean: "I think it'll be good to get out there as a team, we've enjoyed chasing and hopefully we can replicate what we did against Welsh Fire.

"We've not shown our true potential but today we just want to go out there, enjoy it and maybe cause an upset and go out on a high.

"It's not been our year this year but it's always great to be playing at Lord's and hopefully we can show a bit of what's to come next year."

London Spirit captain Charlie Dean wins the toss and chooses to bowl first.

It is crunch time in the women's Hundred as four teams battle to secure the final place in the knockout stages.

First up is Birmingham Phoenix as they face London Spirit needing a result to move back into the top three.

Things could get tense...
