Cox c Rossington b Ellis 22 (Invincibles 71-4)
Breakthrough for London Spirit! They needed that.
Jordan Cox shaped up for a reverse-scoop but doesn't get hold of it, just a tickle through to Adam Rossington.
Nathan Ellis gets his first wicket of this year's Hundred.
Need another 62 to win
Good start from Matthew Critchley. The London Spirit leg-spinner concedes just four from his first five.
The Spirit need wickets, though. We've got a strategic timeout now so they'll have a chance to talk through how to get them.

Desperately in need of a wicket here, has anyone thought about switching the bails around?

Sam Curran and Jordan Cox deal in singles for the remainder of the Liam Dawson five.
The last of them takes Oval Invincibles halfway to their target. We're a little more than halfway through the innings but with wickets in hand, the Invincibles are in a strong position.

Sam Curran has just got the gift to play cricket. That was a tremendous shot.

Smashed through the covers for four!
Brilliant shot from Sam Curran to put a bit of pressure on Liam Dawson.

Curran and Cox are doing really well, they are running between the wickets quickly and getting boundaries when they need to.
Need another 74 to win
We're at the halfway stage and after losing three early wickets, Oval Invincibles have regrouped through Sam Curran and Jordan Cox.
The visitors are favourites as things stand. But it could be a close finish.

Ravi Bopara hides the ball behind his two hands, similarly to Sunil Narine. You can't see what he's going to do, sneaky sneaky.

WinViz is pretty close to sitting on the fence.
It currently has it 56-44 in Oval Invincibles' favour.
Agree?
Cox 12, S Curran 17
Very good comeback from Daryl Mitchell after that first-ball boundary. He concedes just one more from the next four balls.
That slows the momentum Sam Curran and Jordan Cox were just starting to build. Can Ravi Bopara back that up in the next set of five?

The Invincibles are beginning to motor.

He strikes at 142.10 against left-arm spin and averages 27.00.
The left-hander scores quicker - and makes higher scores - against spin so Spirit and Dan Lawrence may return to pace pretty quickly if Curran stays in.
Need another 87 to win
No leg-side slogs just yet from Jordan Cox but Oval Invincibles are able to get moving as Sam Curran slaps a short, wide delivery away for four.
That somewhat ruins what is otherwise a very good very set of five from Liam Dawson.
Steven Finn
Former England bowler on BBC Two
Liam Dawson will be looking to attack the stumps, certainly to the right-hander Jordan Cox.
When I am batting I always have someone sat on my shoulder saying "slog it to the short boundary" and Cox might be the same here.

Image source, Getty ImagesWhat a shot from Sam Curran. He saw it early and just punched it past the fielder. It raced away.
Another Australian seamer is on now, Nathan Ellis.
He's got a great record in white-ball cricket and London Spirit will be glad to have been able to hold him back - he's superb at the death so the more balls he is available for then, the better for the home side.
He starts with three dots to Sam Curran before the England all-rounder pulls the fourth in front of square for four. Top shot!
Oval Invincibles are three wickets down early. Jasn Roy was the first to go...
Dan Worrall has bowled out and what a spell that was form the Aussie fast bowler, two wickets for 23 runs from his 20 balls.
London Spirit are well on top now.
