A front-foot no ball from David Wiese results in a free hit, though the Invincibles cannot take advantage - they will be frustrated with that.
It is a good comeback from Wiese though as he only goes for two singles from his next four balls.
47 runs needed from 25 balls.

Curran is starting to find his groove and starting to get those sixes. It's like Sam Curran is making up for lost time.
Invincibles 107-4
Sweet as a nut!
Sam Curran has stood up and pummelled David Wiese back over his head for another huge six!
That's three sixes for Curran now, he is in the mood.

Invincibles 100-4
Faf de Plessis is looking to go in for the kill as he brings Adil Rashid into the attack.
His England team-mate Sam Curran is having none of it though as he sweeps Rashid away for another massive six. Great shot.
That will liven the crowd up who looked to be losing a bit of energy as the Invincibles' hopes faded.
58 runs needed from the final 30 balls.

Harrison Burridge: Strategic timeout claims another victim. Jordon Cox was looking in control and along with Sam Curran they were guiding the Invincibles on the right path. Very avoidable run out and an opening now for the Superchargers to capitalise on.
WICKET
Cox run out 48 (Invincibles 88-4)
He didn't! A crucial wicket for the Superchargers as Cox goes for 48! It was some really smart fielding by Faf du Plessis and quick glovework by John Simpson.
Umpire review
Ooh, the Jordan Cox attempts a quick single off Bravo's first ball but Sam Curran sends him back - but has he got back in his ground in time?
The umpires send it upstairs, but that looks out to me.

The win predictor had nudged up to 44-56% in the Superchargers' favour.
Here is Dwayne Bravo.
Invincibles 88-3
Shot!
Absolutely textbook from Jordan Cox as plays a drive as straight as an arrow right down the ground for four.
A single nudges him to 48 from 28 balls.
Time for a strategic timeout.

Cox and Curran are just bringing the Invincibles back in the game and they've still got Hilton Cartwright to come out and he hit some monsters here at The Oval last year. The Invincibles are just creeping up and these two are doing really well for their team.

Edged...but away for four!
Craig Miles bowls wide and full, Jordan Cox gets a touch of bat on it and the ball fizzes away past the despairing dive of the wicketkeeper for four.

Absolutely hammered. It's a fifty partnership for Curran and Cox now.

That's more like it! Sam Curran finally comes to the party by powering the ball away into the off side for a huge six!

Invincibles 65-3
Unsurprisingly Adil Rashid bowls a 10-ball spell but his figures are ruined a touch when Jordan Cox seizes on a short delivery and smacks the ball down the ground for four.
Cox has quietly moved on to 35 from just 22 deliveries.
Invincibles 57-3
101 runs needed to win
Adil Rashid, one of the best spinners in the world, comes onto the attack and goes for just nine runs in his first five-ball spell.
The Invincibles are trundling along and have stemmed the flow of wickets, but you feel they need to step it up in terms of runs in the next few balls.
Post update
Superchargers wicketkeeper John Simpson is on the on-pitch mic: "They have put away a few boundaries but we are ahead of the game. I think if we get Curran or Cox out in the next 10 or 15 balls then we'll be good.
"It's about keeping things as simple as we can and keeping to the plans we've talked about. Hopefully we get a catch in this over."

He shows no respect for his elders as he heaves Dwayne Bravo away for a huge six.
