Emily Arlott, who has two wickets for just four runs, has five balls left and she's going to bowl them now.
Poor Phoenix are bowled out for just 82 in 94 balls
Spirit field superbly, pulling off two run outs and Dattani & Monaghan completing a relay catch on the boundary
Phoenix reduce Spirit to 26-6 in reply
But Dattani (28*) and Scrivens (26*) combine brilliantly to get their side home with three balls to spare
Defeat means Phoenix miss out on knockouts; Spirit win only their second game

Dattani goes hard down the ground and that changes everything!
Need 12 runs to win
Single, dot, FOUR!
Naomi Dattani gets the boundary that Spirit so desperately needed with a gloriously timed drive down the ground.
Here we go.
10 balls. 12 runs.
Need 17 runs to win
Naomi Dattani wants a boundary but can only hit it straight back at Kirstie Gordon, who leaps like a salmon but the ball just evades her left hand.

Birmingham Phoenix have to take a risk if they want to win. London Spirit will keep taking singles.
Need 18 runs to win
This is where it gets tense!
Which way is this one going to go? The odds say Spirit, but this game has been far from predictable so far.

If Birmingham Phoenix want to win this, they need a wicket now!
Bit of innovation from Scrivens, ramping Georgia Elwiss over her shoulder and does well to run two, making it back safely with a good dive.
Need 23 runs to win
Smart cricket from Naomi Dattani, who holds the key to this innings and can guide young Scrivens along with her.
Scrivens hits the ball into a gap in the leg side and Dattani immediately yells for two, which they make comfortably in the end.

That was an insane attempt at a run! Had that been accurate, Phoenix could've got the wicket.
Target 83
Oooh, the first signs of nerves from Grace Scrivens, who has been remarkably calm for an 18-year-old in this situation. She sets off for a calamitous run when the ball has just plopped in front of her feet, but Dattani wisely sends her back.
25 balls. 28 runs.
Here's the moment that started the collapse for Spirit. A piece of brilliance from Sophie Devine.
Bad news for Emily Arlott. After 11 balls and two wickets, she has conceded a run.

Just one partnership is what London Spirit needed.
Daniel Norcross

This is bubbling up to a tight finish but if Phoenix pick up a few wickets, that could be it.
Target 83
Singles, singles, singles.
It's ticking down nicely for Spirit but they're not running away with it, so Phoenix will still feel like they're in the game.
Target 83
Simple but smart cricket from Dattani and Scrivens, just ticking over in singles which is all they need.
A handy little partnership is building, but whenever that's happened previously in the innings, someone's done something silly and got out. Can these two withstand the pressure?

If you're a Birmingham Phoenix player here, just keep Dattani off strike.
