Invincibles have gone about this chase the right way, not playing too many extravagant shots and keeping the scoreboard ticking along. They've also been helped along the way with the extras offered by Spirit.
The attendance today is an impressive 11,591. Brilliant.
Invincibles 70-2
Need 34 runs to win
Wilson may have gone but that hasn't stopped Georgia Adams from continuing the charge as Heather Knight is drilled through the leg side for four.

It's so unfortunate for Fran Wilson - when you're struggling for form you find unusual ways to get out. She was so far out of the crease, it allowed Tammy Beaumont to fumble it at first.
WICKET
Wilson st Beaumont b Dean 22 (Invincibles 63-2)
Spirit needed this!
Fran Wilson takes a few steps forward and looks to reverse sweep Charlotte Dean but makes a bit of a mess of it, with her bat flying through the air. Wicketkeeper Tammy Beaumont juggles the ball before whipping off the bails.

Four more as Wilson moves across her crease and sweeps Charlotte Dean for four down to the fine-leg boundary.

Need 47 to win
We're halfway through this innings and Invincibles are looking as comfortable as can be.

Brilliant from Fran Wilson - excellent use of the feet.
Invincibles 54-1
Need 50 to win
Fran Wilson dances down the track and clubs Munro through the leg side for four. Timed to perfection!
Make that consecutive boundaries as Wilson drags the ball past backward square leg. She's making it look easy out there!

In this situation when the batting team don't feel under pressure, their level of risk goes down so there are not as many opportunities for the bowling side.
Invincibles 46-1
Need 58 to win
Deepti Sharma, bowling with her sunglasses on, delivers a tight and tidy line.
She's more than capable of finding a breakthrough but doesn't threaten the settled Invincibles batters.
Spirit need to find some magic from somewhere.
Invincibles 44-1
Need 60 to win
Adams and Wilson dealing in singles with five off Munro's set.
No need to take any unnecessary risks.
Invincibles 40-1
Need 64 to win
Gibson is having a tough time out there, again bowling too wide outside the off stump to gift Invincibles one more.
Adams prods to the off side for a single to end that set of five.
Invincibles 38-1
Need 66 to win
Danielle Gibson comes into the attack. Adams runs through a quick single, taking on the lethal arm of Deandra Dottin, but is comfortably home.
GIbson then bowls ridiculously wide, almost off the square. And again!! And this time it beats the 'keeper and goes through for five wides.

There is no real pressure on these two and the scoring rate as they are well in control.

One thing Spirit didn't too well in their innings was running between the wicket.
Invincibles 31-1
Need 73 runs to win
Three more singles to Invincibles. A decent partnership here and they can play Spirit out of the game.
