Van Niekirk (67 not out) and Adams (42) help Invincibles to eight-wicket win
Burns (45) top scores in Phoenix's 129-9 after home side win toss
Farrant takes 3-23 in her 20 balls, Van Niekirk 2-16
Burns c Gibbs b Gregory 45 (Phoenix 85-6)
Ah!
Danielle Gregory drags one down, and Erin Burns can literally hit this anywhere, but she pulls it straight to Grace Gibbs at deep mid-wicket.
That's still a very good innings from Burns.

Van Niekerk stayed on the floor and did a few swimming moves. It didn't help her get any nearer to the ball!
Burns 44, Wong 3
Four more for Erin Burns! This is the third or fourth time she's hit the final ball of the set to the boundary. This time it comes via a beautiful cover drive.
Dane van Niekerk gets a very early dive out to try claw it in before the boundary, but she gets nowhere near it. She then does a bit of breaststroke on the outfield, and has a laugh with the crowd. That's lovely to see.
Here's how Invincibles skipper Dane van Niekerk picked up the crucial wicket of her counterpart Amy Jones.

At the moment, Erin Burns is forging ahead. She's scored over half the runs and looks to be playing on a different pitch.
Lovely!
Erin Burns picks up her sixth boundary with a lovely flick over square leg.
She's up to 40 off 24 balls now. A crucial hand.
Good again from Erin Burns.
She picks up three more with a nice reverse lap.
Issy Wong hit 27 off 11 balls on Sunday so this could be fun!

Phoenix just can't get a decent partnership going.
Georgia Elwiss looks to down big down the ground, but just hits the 16-year-old Alice Capsey straight down the throat of Jo Gardner at long-on. What a tournament Capsey is having.

That's a lovely shot.
There is a really healthy crowd in at Edgbaston again today. Over 126,000 people have been at the women's games in this tournament so far.
Oh, that's a shot! Erin Burns finishes the set with another boundary, this time a gorgeous cover drive. She'd only scored 22 runs in the tournament before today. She's up to 29 now.
Shot!
The pressure is on Birmingham Phoenix here, but Erin Burns is playing a nice hand. She picks up another boundary with a lovely reverse sweep past short third.
She's up to 26 off 19 balls.

This wicket is starting to look a bit slower and lower, which is why Van Niekerk has brought herself on. I think these matches could be low-scoring affairs.

Verma was bowing her head as she walked off; she couldn't believe it.

Jo Gardner was pretty close to the rope - she had to steady herself and maintain her balance.
Verma c Gardner b Gray 16 (Phoenix 51-4)
Ah! Another big breakthrough.
It's really clever bowling from Eva Grey. It's the knuckle ball, and it deceives Shafali Verma who hits to Jo Gardner at long-on. Gardner started to run in, and looked to be misjudging it, but she did well to steady herself and take the catch.
That is just 71 runs in five innings for Verma now. She hasn't got going in this tournament.
Three in a row!
Another pull from Erin Burns, as he gets it fine, past Danielle Gregory and away to the boundary.
She's up to 18.
Four more!
The pace of Eva Gray is into the attack, and she is greeted by a crunching pull to the boundary by Erin Burns.
Take that.
