The Invincibles are up and running in the chase with a risky single!

Lauren Winfield-Hill hit Danielle Gibson into the covers and set off for one. The fielder gathered it cleanly, though, and a direct hit would have done for Winfield-Hill.

Oval Invincibles will still be confident of knocking off these runs, though, and openers Lauren Winfield-Hill and Suzie Bates are out there ready to begin that process...

The final wicket partnership was 31 runs and they are crucial runs for London Spirit. We were thinking they would be doing well to reach the 100 mark so they've done very well from where they were.

Thanks, Ffion. That last-wicket stand between Lauren Filer and Tara Norris has certainly given London Spirit a chance.

Given they looked down and out at one stage, they'll be happy to still be in the game.

And here they come, led by Heather Knight.

At the halfway mark, you'd certainly have Oval Invincibles as favourites.

But London Spirit's little burst at the end could mean that they take the momentum into the second innings.

So, on that note, here's Sam Drury to take you through it.

Oval Invincibles bowler Sophia Smale on Sky Sports: "I feel like I've been low on wickets so it was nice to get a couple today. I was just trying to make sure that I target the pads a little more than I have been.

"There is a bit in the pitch when you hit your good areas. But it should be good to bat on if there is some width on offer.

"Lauren Winfield-Hill just told me to bowl my best ball and that helped me out and helped me keep it simple.

"We'd have taken that score at the start of that so I'm hopeful we'll chase it and I'm not needed to bat!"

The spinners then got to work in the middle overs.

Sophia Smale and Mady Villiers took two wickets each, to go with Kapp's 2-13 and Ryana Macdonald-Gay's 2-25.

The defending champions were then firmly in control after this little bit of chaos.

It feels inevitable now that Marizanne Kapp will do something special every time she takes the field for Oval Invincibles.

She started the Spirit's collapse, removing Niamh Holland second ball and the captain Heather Knight shortly after.

Well, it was a disappointing start but Lauren Filer has finished the innings with a flourish.

The last wicket of Filer and Tara Norris has added a very valuable 31 from 22 balls.

It still feels under par, but it looked like a good pitch to bowl on so they have something to work with.

Oval Invincibles need 119 to win.

Lauren Filer will be submitting that form to move up from number 11 after this game because that was a brilliant stroke down the ground.

Four more!

Lauren Filer is playing a very useful little knock here.

Spirit 112-9published at 98 balls

98 balls

Oh, lovely! A full toss from Alice Capsey is smacked for six by number 11 Lauren Filer!

Alice Capsey gets away with it.

Just a couple of singles to Norris and Filer with five balls to go.

Oval Invincibles have to bowl their final eight balls (if it goes that far) with one less fielder on the boundary because of the amount of time it has taken them to get through the innings so far.

Can Spirit capitalise?

Something for London Spirit to cheer as a Tara Norris boundary brings them to 100.

What can their last pair get from the final 10 balls?

A streaky edge, a thump down the ground and a wide help edge Spirit a little nearer to the run-a-ball mark.

Oval Invincibles' fielding has been excellent throughout the afternoon.

Lauren Filer is the last batter in for London Spirit.

Can they get to 100 at least?!

Trapped in front. The London Spirit are faltering here. This hasn't quite been the spectacle we imagined.
