That's a fantastic set of five from Usama Mir, he concedes four and even gets Glenn Phillips to play and miss at a quick leg spinner.
Jos Buttler does indeed turn to spin with Usama Mir into the attack.

Spin will play a big part here to slow things down. Even though we've had all of the rain, everything with pace on is flying off the middle of the bat.
Interestingly in T20s Luke Wells only averages 15.68 against pace, compared to 23.57 against spin.
He does strike 137.96 against pace compared to 124.06 against spin though.
What does Jos Buttler do here?
Wells 29, Phillips 1
What a knock this has been from Luke Wells so far! He ends the latest set of five with his fifth boundary, pulled into the gap!
It's a one-man onslaught so far for the Fire.
Glenn Phillips is the new batter for Welsh Fire and he is more than capable clearing the ropes at Sophia Gardens.
He's kept quiet for now by tall Pal Walter but Luke Wells keeps going, he pulls away for four more!
Dot ball to finish that five from Josh Little.
That's a good comeback after being launched for that enormous six by Luke Wells.
We're a quarter of the way through the innings...

Joe Clarke is having a difficult time with the Welsh Fire, he would've been hoping to put on a few runs. His season has got off to the worst possible start with a golden duck. A very smart catch from Ashton Turner.
Clarke c Turner b Little 0 (Fire 25-1)
Smashed straight to cover - brilliant low catch!
It's the first ball that Joe Clarke faced, he hit it well enough and Ashton Turner takes it superbly a couple of inches off the ground.
Josh Little strikes in his first set.

My goodness, what a hit from Luke Wells.
Nailed all the way into the crowd! What a hit from Luke Wells - that has gone a long, long way!
Luke Wells is flying! Josh Little has replaced Josh Tongue but he gets the treatment as well - launched down the ground for a one-bounce four.

I think we're going to see a lot of balls plug due to the weather, there's going to be a lot of running for the batters.
With only 40 balls to play with, it's no surprise to see Luke Wells swinging at everything!
He heaves Josh Tongue away for four more and after ducking a bouncer, Wells swings again and the ball flicks off his pads for four leg byes.
Good start for the Fire.
Josh Tongue will bowl the first set and after starting with a wide, Luke Wells hammers the first legal delivery back past the England man for four!
We're off!
Jos Buttler leads out half the Manchester Originals team, running through a corridor of fireworks - the bowlers were already out warming up - and here come the Welsh Fire openers.
Even 10 minutes ago it seemed unlikely, but we are going to have some cricket in Cardiff today!
Welsh fire captain Tom Abell: "We probably would've had a bowl as well. To be honest, it's all good, batting first can work, hopefully we can put on a good score."
Changes to the Welsh Fire team: "We've got a really new group, we're really excited with the group we've got and we're excited looking forward to getting going."
On Haris Rauf and Shaheen Afridi: "It's great to have the likes of Haris and Shaheen in our ranks, we're really looking forward to seeing them."
Right then, it look like we are going to start at 17:00 BST under leaden skies in Cardiff.
It'll be a maximum of 10 balls per bowler. Still more than enough for Shaheen Afridi to do a bit of damage later, surely?
First, though, it'll be the turn of Joshs Tongue and Little - and the rest of the Manchester Originals attack to show what they can do.
It's going to be a 40 balls per side contest with a 10-ball powerplay.
Better news from Sophia Gardens, the rain has stopped!
The covers are coming off and we've even got a restart time of 17:00 BST.
We'll let you know how many balls per side that will be and so on.
