David Willey is the next bowler into the attack. His first two balls go for two singles.

Anything upwards of forty [more runs] would be good finish to the innings. It's been a struggle but they've found a little bit of rhythm in the last ten balls and hopefully they can maintain that.
Fire 87-4
With twenty balls to go you feel like Welsh Fire will go all-out now.

A welcome relief for Welsh Fire. A great shot from Du Plooy.
Fire 86-4
Our first six!
Leus du Plooy takes two steps down the wicket before smashing Wayne Parnell over the top for a maximum.

That's really good cricket. He's just hit two boundaries. Clever cricket from Duckett.
Fire 79-4
Duckett 41, Du Plooy 10
And Duckett finishes Miles' set with a two to the leg side. That's 10 runs from the last three balls.

Another brilliant shot from Duckett!
Fire 77-4
Two in two, boundaries at Sophia Gardens are like buses. Another short ball is pulled away for four.

A great bit of fielding from Wiese but not enough to stop that boundary. A welcome boundary and Duckett picked that gap perfectly.
Fire 73-4
Here we go. Ben Duckett pulls Craig Miles away for four.
Fire 69-4
Duckett 31, Du Plooy 10
Craig Miles is next into the attack.
When will the Fire accelerate and start swinging?

There doesn't seem to be a huge amount of intent and there is no pressure being applied to the Northern Superchargers.

We're not seeing any big swings or drives from Duckett. They need to work out what a winning score is.
Fire 67-4
Only 30 balls remain.
Even if Welsh Fire score another 50 runs they'll only end up on 117. That seems well below par.

I like the intent there from Du Plooy. He's trying to strike the ball around the pitch and get a few runs.
Fire 66-4
David Wiese is bowling a very good length, keeping things tight. His first three balls go for four runs.
Fire 62-4
A great set of 20 from Adil Rashid who finishes with figures of 1-17.
He's put the Superchargers in a brilliant position. The Fire are going nowhere!

Rashid is not being predictable which is really good to see.
