Jo Gardner puts down a sitter off deep square leg. That should have been taken.
Fire 40-0
Tammy Beaumont is at it again!
Four over extra cover this time.
How's stat?!
Generally Tammy Beaumont does struggle against left-arm pace.
She averages just 14.85 against the bowling type, which is comfortably her worse in T20s.
She has started well against Alexa Stonehouse and Naomi Dattani though.
Post update
Trent Rockets turn back to left-armer Alexa Stonehouse...
Fire 35-0
Tammy Beaumont is piling on the pressure.
After Naomi Dattani bowls a wide, Beaumont latches onto a short ball and whips it behind square on the leg side.
The diminutive England opener has six boundaries already in her 28 from 13 balls. It's almost like she's making a point to those who said she bats too slowly.
Fire 30-0
And again!
Tammy Beaumont drives Naomi Dattani as straight as can be for four more.
Fire 26-0
Biff!
Spinner Bryony Smith is next into the attack and Tammy Beaumont cracks her back down the ground. She follows that with a cut for four before lifting the last ball of the set all the way into the stands.
Superb batting!
Fire 12-0
Tammy Beaumont gets into her work by sweeping Kirstie Gordon off her stumps. Sophia Dunkley sees what her batting has done and thinks "I'd like a bit of that". She adds four too.
Fire 2-0
Dunkley 1, Beaumont 1
That's a good start from teenager Stonehouse. She concedes just the two from the first five balls up against two England internationals.
Fire 1-0
There's a bit of swing here for left-armer Stonehouse. England batter Sophia Dunkley goes for a bit of a hack and gets a single.
Fire 0-0
18-year-old seamer Alexa Stonehouse is going to take the new ball.

There looks to be a very strong breeze blowing across Sophia Gardens. That may have an impact.
We're almost ready to go.
