Rodrigues c & b Dunkley 14 (Superchargers 44-1)
Sophia Dunkley takes a stunner off her own bowling!
Jemimah Rodrigues tries to take down the leg-spinner but can only drill the ball firmly back at the bowler. Dunkley takes a smart catch, diving low to her left, and gets Welsh Fire a much-needed breakthrough.
Georgia Elwiss' medium pace is introduced and Rodrigues and Kelly just tick over five runs from a tidy start.
And it was a tough chance, but Jemimah Rodrigues was dropped on 0.
Another crunching pull shot from Marie Kelly completes a dominant powerplay for the Northern Superchargers.
Welsh Fire need to break this partnership.
The home side are dealing in boundaries!
Claire Nicholas starts with a couple of dots before Marie Kelly has enough of that, and clubs one down the ground for four more.
Nicholas then sends down a full toss that Kelly gratefully accepts, and it gets the same result.
An aggressive start from the Superchargers.
Marie Kelly skips down the pitch and smacks Freya Davies over her head for another boundary.
Nothing streaky about the next two.
Rodrigues helps herself to back-to-back boundaries off Hartley, one down the ground and the next over cover.
Beautiful timing from the India superstar.
Superchargers 9-0
Oh!
Jemimah Rodrigues smacks Alex Hartley's first ball to mid-off, where a leaping Freya Davies gets two hands to it but can only parry it up like a goalkeeper tapping it over the bar.
To make matters worse, the ball ends up going for four.
The home side get off the mark with a lovely drive for four from the bat of Marie Kelly.
Alex Hartley leads out the Welsh Fire, which is a nice touch.
They have a huddle, and are followed by Superchargers openers Jemimah Rodrigues and Marie Kelly.
There are a couple of good match-ups that Tammy Beaumont can exploit with her bowlers today.
Freya Davies v Jemimah Rodrigues Head to head in T20s: 4 innings, 19 runs, 21 balls, 3 dismissals, Average 6.33.
Shabnim Ismail v Phoebe Litchfield Head to head in T20s: 2 innings, 1 run, 7 balls, 2 dismissals, Average 0.50.
In case you haven't already seen, Alex Hartley has announced that she will retire after The Hundred.
The 29-year-old was part of England's 2017 World Cup-winning squad.
Hartley took a break from cricket in May to focus on her mental health before returning for The Hundred with Welsh Fire earlier this month.
She spoke about her decision on the No Balls podcast, which you can listen to here.

Welsh Fire captain Tammy Beaumont on Sky Sports: "We wanted to bat first too, but if you want to win competitions, you've got to win by doing things both ways around.
"There's a lot at stake for us. It's either a rehearsal for the eliminator on Saturday or a chance to get straight to Lord's.
"We are focused on maintaining our winning run."
Northern Superchargers captain Hollie Armitage on Sky Sports: "It's always a good pitch here so we're happy to put a total on the board. The home crowd always helps us.
"They are great here, and we love putting on a show for them. It's a big game. It would be nice to have Saturday off and get straight into the final but we're fully focused on today and not looking too far ahead."
Hollie Armitage gets her way at her home ground of Headingley, and Northern Superchargers are going to bat first.
Welsh Fire captain Tammy Beaumont admits she'd have done the same.
Good afternoon!
Welcome to today's Hundred action as Welsh Fire and Northern Superchargers continue their scrap (with Southern Brave) to secure direct entry into the final on Sunday.
All three have already qualified so it's just about nailing down that final spot. Brave look most likely to claim it because of a superior points tally, so this is looking most like an Eliminator warm-up for both sides.
