That was a pace-on delivery and a great innovation to find the boundary.
Fire 85-4
74 runs needed
Super shot from Ben Duckett! Full from Milnes and Duckett uses the pace and reverse ramps it - all the way for six!
The Fire need plenty more of those.

A really clever piece of bowling, he mixed his pace up and caused an amount of pressure the Welsh Fire didn't know what to do.
WICKET
Miller c Milnes b T Curran 3 (Fire 77-4)
Big wicket! Has Tom Curran just extinguished the Fire? (Sorry.)
Miller seemed to get hold of that but those square boundaries are so big that it still never looked like clearing Milnes at deep mid wicket.
Superb again from Curran, he has exploited the conditions at Cardiff to perfection so far.

It was all looking so good for the Fire when Joe Clarke was firing earlier in the innings. Now they find themselves right up against it...
Miller dropped on 1 by Tom Curran
Smashed back at the bowler and the ball bursts through the hands of Tom Curran in his follow through.
It was the slower ball from Curran that deceived the left-hander but he couldn't cling on to take the crucial wicket.
Fire 75-3
84 runs needed
After a good start, that target is looking further and further away for Welsh Fire. Narine has now taken 2-11 from 15 balls, he's been a big part of this Invincibles fightback.
David Miller is in for the Fire, though, he knows he way around a run chase so all hope is not lost for the home side.

He got his feet into a funny position, he was thinking of reversing it but he got into a real pickle. A strange dismissal.
WICKET
Pope b Narine 0 (Fire 73-3)

Bowled 'im! Ollie Pope has got himself into a horrible mess.
He went to play the reverse sweep, decided midway through it that he was better going for the conventional option, all the while the ball from Sunil Narine was getting ever closer.
Pope misses, Narine hits and the Fire are in trouble.
Fire 72-2
87 runs left
That is a fantastic set from Tom Curran, four dot balls and a wicket. The first maiden of this year's tournament and it's a wicket maiden.
The pressure is just starting to build on the Fire.

A really big wicket and really clever from Tom Curran, he set it up and signposted what he wanted to do. That might just shift things now.
WICKET
Clarke c S Curran b T Curran 37 (Fire 72-2)
Keeping it in the family!
Slower ball from Tom Curran, Joe Clarke tries to deposit it over the ropes but picks out Sam Curran on the deep mid wicket boundary.
Don't forget!
You can watch the Commonwealth Games gold medal match on the BBC shortly.
That's a real freebie for Clarke. It's a slower ball from Hasnain but short, wide and just asking to be hit.
Clarke obliges and gets four down past backward point. A useful boundary for the Fire to keep the required rate in check.

When it gets to over two runs a ball, you are struggling but this will be a good chase. The Win Predictor is fickle!
Fire 66-1
It might be time for Clarke to stop trying that ramp shot! For the second time in the match, he only gets a toe-end on it but this time the ball shoots up and hits him on the grille of the helmet.
He seems OK but the physio is coming out to make sure.

Very good again from Milnes. Duckett pulls the first ball for two but just two singles come from the next four.
We're reached the halfway stage and this one is poised very nicely indeed.
