Billings c Abell b Payne 4 (Invincibles 100-6)

S Curran c Van der Merwe b Green 1 (Invincibles 89-4)
Green's got a wicket of his own!
England all-rounder Sam Curran picks Van Der Merwe on the boundary. That could be vital.
50 runs needed
In comes Sam Curran and he takes a single through backward point for his first runs.
Cox c Green b Shaheen 51 (Invincibles 88-3)
Shaheen is back and he's in the wickets!
Big square slog from Jordan Cox and Ben Green is waiting at square - the ball seems to be following him around. He just over balances having taken the catch on the rope, pops the ball in the air, steadies himself and grabs the ball again.
51 runs needed
A no doubt furious Rauf responds with a lovely block-hole yorker.
Cox scampers across his stumps for the big sweep again, if he gets any further he'll end up somewhere near point.
Rauf follows him with the ball and Cox can only top edge - the ball skews away for a single behind the keeper.
54 runs needed
Big from Klaasen - using the pace of Haris Rauf and lifting him high over mid-wicket.
I'm not sure any of the crowd down there would have seen the ball coming - there's a glorious sunset over the back of the Oval stands.
60 runs needed
Fifty for Cox!
He breaks the boundary dam, stepping outside his off stump again to sweep hard for four.
A push down the ground for one brings up the fifty from 39 balls.
Klaasen takes a single from the final ball of Ben Green's set and we'll have a strategic time-out.
68 runs needed
Invincibles work five singles off the darts of Roelof van der Merwe.
No boundaries in the last three sets.
73 runs needed
Klaasen scrambles through from a single off David Payne's final ball. The bowler kicks the ball onto the stumps, bur Jordan Cox is home.
The game is interestingly poised. Cox's explosives were a fair few balls ago and the Invincibles need to do more in the second half than they did in the first. But they do have wickets in hand.
77 runs needed
Strong set from Haris Rauf, three singles and then two dots.
Cox takes a big swing at the final ball and gets some stern words from Rauf for his troubles.
81 runs needed
Heinrich Klaasen defends the final ball of the set.
Jacks c Green b Van der Merwe 16 (Invincibles 57-1)
Ben Green holds on this time!
Jacks drills new bowler Roelof van der Merwe through the covers for four but he's gone next ball, dropping a high ball into the hands of the waiting Green at long off.
Cox 38, Jacks 12
Cox stands almost entirely outside his off stump to sweep Ben Green for two.
Cox lifts Green high down the ground and holds his pose. The ball plugs just short of the boundary and they run two more.
Absolutely wild set from Haris Rauf, steaming in at 90mph and more.
He tumbles over in his opening delivery follow-through and then looks furious after he's rightly no-balled for a bouncer that flies over the head of Will Jacks.
Jacks then edges and the ball races away for four, but Rauf responds by twice beating the bat.
Grounded.
This time Glenn Phillips hasn't caught it cleanly.
But have Welsh Fire got their man? Once again the ball flies to a diving Glenn Phillips at backward point. Cox might be gone.
As with Jason Roy, the umpires are checking this one. There's a soft signal of out.
That is absolutely huge from Jordan Cox!
He drops David Payne for a huge spiralling six over mid-wicket.
And again! Jordan Cox is looking in lovely touch, this time feasting off the bowling of David Willey - powering a four past mid-on and then another boundary through the covers.
Cox moves to 21 off 14.
Two lovely shots through the covers bring fours for Jordan Cox off Shaheen.
