Chappell responds well.
Just three coming from his next two balls.
Need 24 from 9 balls
Matt Critchley has not given up here!
He clubs Zak Chappell over mid-wicket for four.
Need 28 from 10 balls
Great finish from Sam Curran.
But there's a problem for the Invincibles here. The cut-off time is approaching, which means they must start their last five balls quickly to avoid having to bring an extra fielder in from the boundary.
I don't think they're going to make it.
Need 29 from 11 balls
Sam Curran fights back with a couple of precious dot balls.

Matt Critchley! Suddenly the equation is much more manageable.
Need 29 from 13 balls
Is he going to do it in sixes?!
Matt Critchley goes back-to-back.
Matt Critchley goes big!
He gets the six with a bit of help from Will Jacks, who steadies himself for a catch at long-on but treads on the boundary sponge.

From what was looking like a tantalising finish, now looks like a mountain to climb for Spirit, all in the space of three balls.
Adam Zampa finishes with 2-24, a fine start to his stint at The Oval.
Spirit need an unlikely 41 to win from 15 balls.
Lawrence c Roy b Zampa 24 (Spirit 148-6)
Is that the game?
Dan Lawrence can't believe it. He raises a hand to his head in disappointment as he clubs Adam Zampa down the ground, gets a very good connection to it but picks out Jason Roy at long-on.
Mitchell lbw b Zampa 4 (Spirit 147-5)
If Spirit are going to do it, Dan Lawrence may have to do it by himself.
Daryl Mitchell takes a big swing at Adam Zampa and is given lbw.
He doesn't bother with a review and Oval Invincibles edge closer to victory.
The win predictor is favouring Oval Invincibles, with London Spirit needing 44 to win from the last 20 balls.
But crucially, Dan Lawrence is there with 24 from just nine balls.

It was spinning away from the left-handed Wade so all he could do was spoon it up.
Wade c Whiteley b Sowter 19 (Spirit 142-4)
Nathan Sowter strikes!
His first set of five balls went for 16, so he is understandably delighted with this wicket.
Matthew Wade tries to keep his aggression going but looks at the toe of his bat in disgust as he slices a catch to Ross Whiteley at cover.
A tough couple of balls for Will Jacks but he started his spell emphatically by removing Michael Pepper and Adam Rossington within his first five balls.
The latter was the biggest breakthrough, who looked intent on steering his side home before falling for 61 from just 32 balls.
The ball seems to slip out of Will Jacks' hand and reaches Matthew Wade at head-height, who does well to steer it over the keeper for four.
The free hit is then clattered down the ground with much more conviction.
Nice of Jacks to let Wade get himself going. He was struggling for timing a bit previously.

Lawrence got a good piece of that one!
Target 190
Spencer Johnson returns... and is greeted by back-to-back sixes from Dan Lawrence!
The first hangs in the air for an age before landing safely over the cover boundary, teasing every fielder.
The second is much more authoritative, crunched over mid-wicket and into the crowd.
Lawrence believes.
London Spirit started their chase powerfully, with an opening stand of 94 from 50 balls between Zak Crawley and Adam Rossington.
But Sam Curran got the breakthrough, bang on the halfway mark.

A beautiful strike.
