Georgia Hennessy can't find a good length. No sixes so far in this innings, and they need seven now to reach the eliminators. It's looking very unlikely.
Spirit 55-3
Need 41 runs to win
Another big four from Gibson! Great start for the young batter - maybe she should've opened!
Spirit 51-3
Need 45 runs to win
Not a great start from Georgia Hennessy, who gives Danielle Gibson two freebies down the leg side that she guides for four.
Spirit 43-3
Need 53 runs to win
It was always going to take something spectacular to take Spirit through to the eliminator.
To get there, they now need 53 from just 11 balls.
Heather Knight helps herself to four more but it's probably not going to be enough.

It will be very interesting to see how long London Spirit go for it, and what happens post that. Deandra Dottin tried to play a very difficult cricket shot.

Dottin c Cleary b Matthews 12 (Spirit 36-3)
Dottin goes, and surely Spirit's hopes with her. It was another attempt at a boundary but Piepa Cleary gratefully accepts the catch. Will Spirit keep going for the eliminator place, or is their focus now on just winning the game?
Spirit 34-2
Need 62 runs to win
A massive slog from Deandra Dottin gets her another four. She could do with it just going a little bit further for six.
Spirit 28-2
Need 68 runs to win
OK, so let me just gather my thoughts. Spirit 68 from 21 balls to overtake Birmingham Phoenix in third place and secure their place in the eliminator.
It's a big ask.

I'm really surprised Deandra Dottin hasn't opened the batting and is just coming in now. London Spirit have missed a trick here. That first boundary she hasn't had a look, it's stand and deliver cricket. I hope she bats for the remaining balls because she is on one.
Spirit 27-2
Need 69 runs to win
And Dottin's first ball is smashed for four! I'm pretty baffled she didn't open.

Beaumont b Cleary 8 (Spirit 23-2)
Are London Spirit's hopes over? A big swing and a miss from Tammy Beaumont, which she had to do, in fairness.

No disrespect to Tammy Beaumont and Heather Knight but London Spirit need boundaries here. The players from the West Indies can hit them so why haven't London Spirit sent out Deandra Dottin next? I am happy to eat my words as well, though!
Spirit 22-1
Need 74 runs to win
Another four for Knight, this time cut past point. Spirit need a few more of those - they're running out of time.
Spirit 16-1
Heather Knight reverse sweeps her first ball for four! Class.

The experiment hasn't worked. I have to give credit to Hayley Matthews who has understood the situation and taken pace off the ball, bowling slow and wide. It's just a gimme. She's wasted much-needed balls.
WICKET
Tryon c Harvey b Matthews 4 (Spirit 12-1)
And there's the first! That's a shame. The Tryon experiment hasn't worked - and she's also taken up a few balls without scoring which Spirit really didn't need.
Good bowling from Hayley Matthews though - she bowled it slow and wide, forcing Tryon to try and play across the line.

Not much happening from Chloe Tryon so far. She needs to start finding the middle of the bat and run hard. She has nothing to lose so swing hard.
