A direct hit from Tom Abell, and Fire think they have a run out. It looks close.
Superchargers 92-6
Harry Brook is going to do this by himself!
Superchargers 85-6
Some very smart running from Brook and Wiese sees them scamper a couple of twos and keep the score moving along.
Harry Brook has 41 from 20 balls and is set up nicely for a big finish with 30 balls remaining.
Not out
Superchargers 78-6
Good review!
It's too high, and Wiese survives.
Superchargers review
Is it two in two?!
David Wiese is given out lbw but he sends it for a review.
WICKET
Carse c Willey b Wells 9 (Superchargers 78-6)
Another great catch!
Brydon Carse hits Luke Wells' first ball for four but the bowler gets his revenge. Carse tries to heave one into the stands but David Willey charges in from square leg and takes a good running catch, skidding along the turf with the ball quite low off the ground.
Superchargers' counter-attack has been halted.
Superchargers 72-5
Brydon Carse joins Brook, so there is still batting to come for Superchargers, with David Wiese still to come as well.
Superchargers 66-5
Harry Brook is just going to carry on doing his thing.
He swats David Payne through mid-wicket for another four.
Post update
We've seen a couple of decent caught and bowled efforts today.
WICKET
Rashid c & b Van der Merwe 6 (Superchargers 61-5)
Roelof van der Merwe, that is very special!
Adil Rashid absolutely nails it straight back at him - in fact, the umpire is already ducking for cover. But Van der Merwe stays still, hands above his head, and takes a spectacular catch.
Superchargers 61-4
Lockie Ferguson is rapid, but his pace is helping the Superchargers batters at the moment as Adil Rashid whacks one over the covers for four.
They are starting to form a handy little recovery here now. Can they go big in the second half of the innings?
Post update
But nonetheless, it was a brilliant start from Welsh Fire's quick bowlers.
Superchargers 55-4
All of a sudden, Superchargers are in control.
Harry Brook launches his third six and moves to 28 from just 11 balls.
Superchargers 47-4
What a weird shot this is!
Harry Brook uses Ferguson's pace to guide it down to third man, where it looks like Jonny Bairstow is ready for a simple catch. But it somehow flies just over his head for a flat six!
Superchargers 39-4
A bit of fortune for Brook as an outside edge flies past the keeper for four.
Lockie Ferguson's accessory choices are causing quite a stir. He's gone for black spikes, which are quite jarring against the red Fire kit, and has his long hair kept out of his eyes by a matching black headband.
Superchargers 35-4
Pressure? Nah. Harry Brook launches Payne down the ground for a glorious six.
WICKET
Hose c Henry b Payne 15 (Superchargers 28-4)
Four down!
That was in the air for a long, long time. Matt Henry does very well to hold on at fine leg.
Adam Hose was just starting to counter-attack with a four over mid-wicket but David Payne fights back. Hose sweeps, the top edge flies miles and Henry has plenty of time to steady himself under it in the end.
Superchargers 21-3
England star Harry Brook gets his innings started with a four down to fine leg, as Matt Henry strays down the leg side.
He is a player who certainly won't be deterred by his side being three wickets down. Headingley could be in for a treat if he gets going.
Superchargers 18-3
Adam Hose responds to the pressure of three early wickets by ramping David Willey over the keeper for four.
It's a great shot that earns him a bit of luck as a thick edge darts just past the stumps and away for another boundary.
Willey laughs in disbelief but it's still been a dominant powerplay for the visiting side.
WICKET
Lyth b Henry 2 (Superchargers 10-3)
What a start for the Welsh Fire!
Matt Henry has bowled beautifully since his first ball was a wide. He gets a bit of swing and the ball clatters into Adam Lyth's middle stump after he takes a wild swing at it.
After choosing to bat first, Superchargers are 10-3!
