Edged straight out the chimney and Wiese gets the breakthrough, almost immediately.
WICKET
Clarke c Du Plessis b Wiese 14 (Fire 29-2)
The Welsh Fire are under pressure now.
It's a nothing shot from Joe Clarke who tries to ssquirt the ball to the leg side but instead meets the ball with a leading edge and skies it straight to Faf du Plessis.
Clarke goes for a disappointing 14 off 17.

It's so important to have an awareness of what the conditions are. It's not the highest scoring grounds so I think Welsh Fire can afford themselves a little bit of time.
Fire 28-1
New bowler David Wiese continues the economical start for the Superchargers. His first two balls go for two singles.

Not the start of the day the Welsh Fire wanted but I suppose they could a leaf out of the women's book.
Fire 26-1
Clarke 13, Duckett 7
A tidy first set from Rashid, he goes for just three runs off his first five.
It's been very slow going so far.

Adil Rashid is such a skilled bowler, he's able to spin the ball both ways and one of the best in this format.
Fire 23-1
Time for spin. Here comes England's Adil Rashid.

Not the best power play but the way it finished with a couple of boundaries, that will improve their mood.

Fire 22-1
A good finish to the power play as Joe Clarke strikes another four with a streaky shot over backward point.
Fire 18-1
That's more like it. Clarke fires one over the top for four.

Is it all about explosive hitting or is it going to be a bit more nuanced than that?
Fire 14-1
Wayne Parnell continues. He fires in another dot.
Joe Clarke looks to try something different next ball. He attempts a scoop but can't find any contact and the ball goes harmlessly through to the keeper.

Duckett gets the first boundary. He finds the gap at long leg and timed it beautifully.
Fire 14-1
Ben Duckett is the new batter in and he needs just one ball to pick off Miles and get the Fire's first boundary, flicking the ball for four down the leg side.
More of that needed for the hosts. It's been a very slow power play.

Banton has to go! He doesn't even look at the keeper. He knows he has touched it. Thta's disappointing from Banton.
WICKET
Banton c Pepper b Miles 6 (Fire 10-1)
Got him!
Tom Banton feathers Craig Miles through to the keeper and doesn't wait for a decision, walking straight off the square.
His poor form continues and the Fire are in a spot of bother.
Fire 6-0
Wayne Parnell comes in to the attack. Tom Banton immediately chips him over the covers for two.
