Coming up in women's Hundred: Welsh Fire v Southern Brave (Monday, 15:00 BST)
Graham 6, Wolvaardt 50
Easy opener for new batter Heather Graham, a short ball sits up and is sent to the mid-wicket boundary.
Wolvaardt pushes for her fifty - she's playing a key role in this opening position, but she'll need to accelerate to secure her side victory.
Armitage b Lamb 24 (Superchargers 106-3)
That's the partnership breaker from Emma Lamb!
A big swing from Hollie Armitage and she's clean bowled.

One boundary a set isn't going to be enough for the Superchargers, they need an explosive spell from one of their batters or they'll finish short.

What happens in these next 10 balls is going to be key. The Superchargers need a real injection here.
Armitage 19, Wolvaardt 48
Superb fielding from Lizelle Lee! Wolvaardt gets on top of a Cross bouncer, but Lee gets down to cut off the shot in the gully - that was destined for the boundary.
A single from Armitage and that's 100 up for the Superchargers. Here's the time-out...
Armitage 12, Wolvaardt 47

It's another tight set from the England international, only three from it.

That's such a rarity for Ellie Threlkeld, she's very good behind the stumps.
Armitage 11, Wolvaardt 45
Big swing from Woolvardt, charging at Hannah Jones. There's faint contact, and she scrambles to get back in before a fumbling Ellie Threlkeld takes off the bails.
A lovely reverse from Hollie Armitage brings four more, but Superchargers are falling further behind the rate...

It's almost a play-off game this. The loser is going to find it difficult to qualify.
Armitage 6, Wolvaardt 43
Dottin returns, evidently recovered from her heavy landing on the boundary.
Armitage can't quite get her away, picking out fielders in the deep. The Superchargers still aren't halfway to their target, they need bigger sets than this to have any chance of victory.

It's one of those wickets where every time you need a boundary, you can find one. I'd just be telling my partner to hang in there and see what happens.

Chance of a run-out!
Captain Hollie Armitage was on the verge of setting off for a run after Wolvaardt dropped the ball against her pads, but then sends her teammate back. The South African is back in her crease... just.

She's taken a long time to get up there has Deandra Dottin, it was a full Superman-like dive. She's in some discomfort here. She has had shoulder surgery in the past and I wonder if she's just jolted it there.
Armitage 1, Wolvaardt 34
Deandra Dottin is slow to get up as a Wolvaardt pull to mid-wicket evades her dive.
Hopefully this isn't her last contribution in the tournament. No, she's getting up - and can't get to a virtually identical shot from Wolvaardt the following ball.

Heath run out 3 (Superchargers 50-2)
That's close! Beth Heath could be gone here...
Wolvaardt pushes for two after punching to the boundary - Ecclestone at the bowler's ends gathers the throw from the deep a fair distance from the wicket. She dives on the turn and the stumps are just in reach - Beth Heath is short of her ground!
Heath 2, Wolvaardt 18
Emma Lamb arrives as the sixth bowler of the Originals phalanx of options. She holds the Superchargers batters to a single each.
Heath 1, Wolvaardt 17
Image source, Getty ImagesThe pressure falls on Laura Wolvaardt in her new position of opener. And she steps up here, cutely working Dottin to the boundary for two fours.
In comes Beth Heath for the Superchargers. She'll be facing Deandra Dottin, no doubt hoping to deliver an equally remarkable performance with the ball.
