Sam Billings has played nicely. This partnership just needs to develop for a few balls. We know these two can find the boundary.
Invincibles 104-5
Need another 28 to win
London Spirit need to keep Sam Billings off strike, especially while Tom Curran is getting himself set.
A couple of singles to end Liam Dawson's five. But he's going to jog down to the other end and continue for five more.

That is the shot of the night for me. Glorious.
The pressure was just starting to build. He's just said 'I'm going to do it myself'.
Invincibles 102-5
Need another 30 to win
Glorious from Sam Billings.
He dances down the track and whips the ball high over deep mid-wicket for six!
Invincibles 95-5
Need another 37 to win
It looks like this one is going to go down to the wire!
Liam Dawson is coming on to bowl the next five.

It's been a good move to get Matt Crtichely into the attack. He held that one back to get rid of Sam Curran.
WICKET
S Curran lbw b Critchley 34 (Invincibles 93-5)
Gone! This London derby takes another twist!
Slightly shorter and slower from Matt Critchley, Sam Curran missed with the shot off the back foot and was hit in front of leg stump.
Three reds on ball-tracking and Sam Curran has to go. His brother Tom replaces him.

Invincibles 86-4
Need another 46 to win
Decent five for Oval Invincibles after that boundary to start it, nine runs form it in all.
It's not a great pitch for batting but 46 from 30 balls? You've got to fancy the Invincibles to get over the line from here.

Sam Billings doesn't want another thriller, he's whipped a full toss from Jordan Thompson through square leg.
Out to the short boundary for four.
How's stat?!
Oh! WinViz has closed in.
It has it 52-48 in Invincibles' favour.
Are we set for another cracker?
Invincibles 77-4
Need another 55 to win
Super shot from new batter Sam Billings to end Nathan Ellis' set.
It's too full and the Oval Invincibles captain drives elegantly back down the ground for four.

Excellent from Ellis there, he changed the field. Jordan Cox tried to hit it where the fielder came from and used the pace. The tumbling Adam Rossington takes a smart catch.
