Jos Buttler, who we always think of as a boundary smasher, is playing a clever game here with soft hands into the off side and clocking 2s. That's a very seasoned cricket brain on those broad shoulders.

As if by law the ball is now following Dawid Malan. A great start from Shamsi who should have had a wicket with his first ball but still nothing to write home about for the Trent Rockets.

Dawid Malan, you cannot afford to drop Phil Salt when he's in this mood. Salt looks to go big and back over the bowler's head but Malan with the drop off a regulation catch.

Sophie Devine is playing a blinder, the New Zealander looks unstoppable smashing her way to 47 runs off 20 balls.

She's hit two sixes and five fours across the last 10 balls.

The Birmingham Phoenix have counter-attacked and are now on 60-2 off 30 balls.

The introduction of Shamsi will be massive. We saw a lot of spin in the women's game.

Make that three in a row. This time it's Buttler with the boundary.

Run rate now up to just under two a ball.

These two are racing along and the Rockets need to go more attacking.

Back-to-back boundaries.

The ball has been replaced but it's not stopped the intent from the openers as Salt hits another to the mid-wicket boundary.

Phil Salt has flat batted that and launched it over mid-wicket into the building site. He moves on to 24 while a builder in a hi-vis vest hunts for the ball amongst the wreckage of concrete.

Great start from the home side. Jos Buttler just getting going and finding the boundary.

Not been a lot of attacking intent from the Rockets yet. They need to break this partnership.

Welsh Fire are dominating, with a second wicket in the powerplay* having put Birmingham Phoenix into bat first.

Alex Hartley has her first wicket for the Fire as Annabel Sutherland takes a stunning catch, running round at long-on to remove Amy Jones on the dive.

In comes Australia all-rounder Ellyse Perry at four for the visitors, probably one of the biggest names in women's cricket right now.

After 20 balls her side are 20-2.

*Wondering what a powerplay is, allow us to help...

Buttler 15, Salt 16

10. Rows. Back!

Universe Jos with the first six straight back over mid on.

Phil Salt with fast hands and fast feet and a beautiful back-foot shot through extra cover. There was some serious power on that. Not a bad ball either.

Jos Buttler with the scoop. That is trademark Jos Buttler who just helps it over his shoulder and over the boundary.

Here we go. Is it Jos time?

It's not found the boundary but that is a stunning drive from Phil Salt.

Fielded by Alex Hales who is apparently fielding with hand warmers in his pocket...yes, I'm confused too.

No fireworks yet as these two are just rotating the strike. Need to start winding up for some boundary bashing if they hope to post a big total.

A big wicket for Welsh Fire as Eve Jones is bowled by Claire Nicholas after just the sixth ball.

Birmingham Phoenix are on 10-1 after the first 10 deliveries.

The home fans are making plenty of noise as Sophia Gardens slowly fills up.

(Well, it's actually six balls thanks to that wide down the leg side)

Originals haven't come out flying like one might imagine with Buttler out there opening.

Wood traps Phil Salt on the pad and the Rockets look interested.

Seems to be going down leg but excitement already.

It seems pretty obvious who the crowd are supporting...Boos are reverberating around Emirates Old Trafford as the Rockets take to the field.
