Amara Carr used her feet really well there to get into that position to scoop. It's back in the Spirit's favour now.
Spirit 117-6
Smart batting! Carr scoops Issy Wong over the 'keeper for four. Innovative.

Amara Carr is very quick between the wickets and she rotates the strike really well.

WICKET
Sharma c Mack b Burns 28 (Spirit 108-6)
Three wickets in four balls for Birmingham Phoenix!!!
Deepti Sharma jigs down the wicket to Erin Burns and hoicks the ball into the leg side, square of the wicket, and Katie Mack makes no mistake of taking the catch.

What a turnaround! We've had all the emotions in the past five balls!
WICKET
Rowe b Arlott 0 (Spirit 108-5)
Superb form Emily Arlott! New batter Susie Rowe is completely outdone by a yorker, a ball which pitches by the foot of the batter, and is clean bowled.
Not only was it a yorker, it was a slower delivery which completely deceived Rowe.
We have a game on now.

That's a crucial wicket at this stage of the game.
WICKET
Tryon c Elwiss b Arlott 9 (Spirit 108-4)
This one counts as Emily Arlott strikes! A mistimed shot goes into the hands of Georgia Elwiss.
Spirit 104-3
Nearly the breakthrough!
A full toss from Arlott - a ball which does not bounce as it reaches the batter - hits the stumps. But the umpire refers it to the TV umpire who confirms that the ball was above waist height of the batter so is therefore a no-ball.
To add insult to injury, Spirit will now a free hit - meaning the batter can't be lbw, bowled or caught.
Spirit 102-3
Deepti Sharma clubs Kirstie Gordon through the leg side, there are cries of "catch it" but it's well out of the reach of the diving fielder.
Phoenix need something special here.

Spirit need about a run a ball now and that's not a bad position to be in with 30 balls left.

Spirit 97-3
Spirit need 37 runs from 35 balls
Every time the TV cameras pan to the crowds, you see young cricket fans enjoying the game. Love to see it.
Five singles from Georgia Elwiss' five balls; Spirit can afford to just take the singles now and then punish any bad ball which comes their way. It's their to lose.
The best of the action
While we have a time-out, here's some of the best bits from today's game.

Deepti Sharma was struggling early on - not any more!

Poor line again from Wong and it's the same result. Four more.
