Brathwaite c Cracknell b Cullen 30 (Originals 134-9)
London Spirit's young guns are showing tremendous courage here.
Blake Cullen executes a fine wide yorker, Carlos Brathwaite toe ends it and Joe Cracknell takes the catch.
Back Spirit's way?
Originals 134-5
Need nine runs to win
Just two singles as Cullen calms proceedings down slightly.
One ball left to Brathwaite...

Eoin Morgan wanted to give his youngsters experience. This is a great learning curve for Blake Cullen. He's 19, he's gone for a few sixes but he's got some brilliant yorkers and short balls in there too.

You just felt as if Carlos had a big six in him somewhere.

And that's the risk you take bowling a young pace bowler, when you're on a spinning pitch and Carlos Brathwaite is on strike.
The Windies all-rounder marmalises it straight down the ground for a sweet six.
Advantage Originals.

Blake Cullen starts with a superb yorker. Dot ball.

No catch under lights is ever easy, especially when it goes that high.

That is a good catch. It went up miles in the air, he had so much time to think about it.

Ackermann c Inglis b Wheal 53 (Originals 126-5)
Is that the something special?
Colin Ackermann miscues another attempted blow into the stands, skies it up and Josh Inglis steadies himself to pouch it safely.

That is HUGE! And what a way to get to fifty!
50 for Ackermann
Need 19 runs to win
Colin Ackermann has just crushed Brad Wheal's second delivery into the crowd behind mid-wicket.
Such a sweet strike a brilliant way to bring up 50 off just 38 balls.
Advantage Originals, surely?

Crane keeps it tight, conceding just one and twos.
What can he do off the last?
Brathwaite goes for the big heave down the ground and the ball drops agonisingly short of Nabi, who slipped trying to get there.
So six off Crane's final five balls. Still tense this.
