Dane van Niekerk plays the sweep so well. She can literally hit it anywhere from the umpire to behind the wicketkeeper.

Amy Jones has destroyed the stumps. Dane van Niekerk is a bit fortunate there because she would have been miles out if Jones gathered clearly.
Not out
Invincibles 75-2
She's out of the crease but Amy Jones dropped the ball. Criminal!

Even though Dane van Niekerk is one of the best players in the world, you are gambling on her coming off with her not playing much recently.

The Oval Invicibles have got nothing to lose. Can they go out there and get their net run-rate even higher?

Van Niekerk will have a point to prove today. Found herself out of the side in the last couple of games and she'll want to get some runs.

Invincibles 63-2
Target 107
Dane van Niekerk is in at four.
She's happy to block out the last three balls of Emily Arlott's set.
Arlott by the way has figures of 1-2 off 10 balls. A rare bright spark for the Phoenix.

The game is almost done and dusted here for the Invincibles. Birmingham Phoenix will need to come up with something really magical if they want to win this. But, never say never.

That wasn't a great ball. It was halfway down the track and Winfield-Hill had loads of time to pull that past fine leg.
