Both openers now back in the dug out. It does seem too little too late but another wicket goes down.
WICKET
Du Plessis c sub b Sodhi 32
A couple of balls later Du Plessis goes for another big hit but is comfortably caught on the boundary. Just reward for good bowling from Sodhi.
Six for Du Plessis
Target 115
Du Plessis swats Sodhi down the ground for a sweetly timed six, he moves to 32.
Superchargers 76-1
Target 115
An excellent set from Sodhi, a single and a wicket. He's kept on for another five as a result.

Bit disappointing they haven't been very competitive. Lyth looks disappointed but deep down he will know he's done a good job.
WICKET
Lyth c Clarke b Sodhi 47
Just when a fifty looked inevitable, Lyth edges behind to the keeper. An excellent innings ends, the opener has certainly done his job tonight.

It's impossible to create any pressure here. You sense the result is kind of inevitable.

Superchargers 75-0
Target 115
It's the spin of Matt Critchley into the attack. Du Plessis uses his feet again to good effect to collect another boundary, he misses out on the last ball of the set which was a full toss asking to be hit.

Welsh Fire desperately need a wicket.
Superchargers 69-0
Target 115 (Du Plessis 19, Lyth 46)
Fire captain Josh Cobb brings himself on, it's a tidy looking set until Du Plessis uses his feet to chip a four through the leg side.
It's followed by a six, Miller on the boundary can only tip it over the rope.
Superchargers 57-0
Target 115
The Superchargers are almost half way in their chase, Sodhi bowls another good set of five but there's still no sign of a wicket.
A strategic time is called, the Fire really do need to re-group.

It's a walk in the park at the minute unless something drastic happens.

It's cleared the field by a long way and there you go! Another short delivery punished by Lyth.
Superchargers 51-0
Target 115
Lyth takes a liking to pace of Pretorius and hoicks him over mid-wicket into the stands. The team fifty is brought up too.
Superchargers 44-0
Target 115
Ish Sodhi is into the attack and starts by beating Lyth all ends up and almost bowling him with a googly from his second ball. It suddenly looks like a different game for Lyth but he survives.

Another great shot from Lyth who is taking this run chase really quick. Very good stuff.
