Another big mow from Laura Harris, hitting Wareham long and high over long-on.
Superchargers captain Hollie Armitage brings herself onto bowl and offers up a big loopy full-toss that Harris dispatches to the boundary behind square leg. That's six runs - a no ball for a delivery above waist height.
Chaos in the field follows - first Georgia Wareham spills another catch deep on the leg side as Dunkley top edges, before Leah Dobson lets a Harris shot break through to the ropes.
Ballinger fires a ball down the leg-side and Heath, standing up, can't reach it. That's five wides.
The seamer tightens up with four consecutive dots.
Four for Laura Harris, driving Ballinger uppishly. The ball bounces in front of Alice Davidson-Richards, dropping to her knee to field, but the ball deviates slightly after bouncing, breaking through her hands and reaching the boundary.
Davidson-Richardson then fell backwards awkwardly on her wrist and seeks treatment. She seems OK to continue.
It's all going on at Headingley.
Dunkley only just makes her ground running two as Lucy Higham's sharp throw races in from the point boundary.
The umpires take a look and they're called upon again for a stumping chance the following ball. Dunkley's just about grounded her bat after Heath juggled the ball.
The England batter is leading a charmed life.
Davidson-Richard's final ball is a wide and Dunkley hustles through for a second run.
Laura Harris then takes a single to mid-wicket.
Is Sophia Dunkley gone?
She goes to lift the ball straight down the ground, holding the pose. She hasn't timed it well and the ball drops rapidly, not far behind the umpire. Kate Cross runs in from mid-on and takes the catch diving forwards.
Has she grounded the ball though? The umpires think so - the replays are not absolutely conclusive, but it seems probable and the screens say not out.
And now a six for Harris, a massive hoick over mid-wicket!
Laura Harris arrives with an immediate four, cut through point.
That's the end of a dramatic powerplay.
Bryce c Wareham b Ballinger 4 (Fire 14-3)
Finally a catch sticks.
Bryce drops to her knee and tries to loft Ballinger for six over square. She doesn't get enough of it to beat the ropes and it's an easy catch - although maybe not in the context of the last few balls - for Georgia Wareham at square leg.
Can we just check that this ball isn't covered with butter?
It's a third dropped catch for the Superchargers, the ball breaking through Ballinger's hands at knee height as Dunkley drives the ball back at her.
Dunkley then punishes the misfortunate Ballinger by driving her down the ground for four.
Another drop!
A first four for Fire as Sophia Dunkley steps across her off stump and turns Cross down to the fine-leg boundary.
The England batter then cuts uppishly - it should be a simple catch for Grace Ballinger at deep third, but the bowler spills the ball.
Are Superchargers trying to ensure this is a contest? They've taken two wickets but given Fire two lives.
Should have been three down.
Grace Ballinger's first ball cramps Bryce for room and takes the edge. It should be a relatively simple catch for Bess Heath behind the stumps but the ball breaks through her and runs away for two.
Sarah Bryce comes to the middle to meet Sophia Dunkley, who is yet to face a ball.
The Fire keeper gets Dunkley on strike, tucking the ball square for a single. Cross then beats Dunkley's bat.
A fantastic start for the Superchargers.
Matthews c Litchfield b Cross 0 (Fire 0-2)
Two down! And still no Fire runs on the board.
Matthews is gone, perhaps trying to force that first run, she steps down the ground and drives the ball cleanly into the hands of Phoebe Litchfield at mid-on, who drops to her knee to take the catch.
A fantastic start for spinner Lucy Higham as she goes for a run-less first set.
West Indian batter Hayley Matthews has come into bat for Fire.
Beaumont c Cross b Higham 0 (Fire 0-1)
A remarkable start!
Tournament leading run scorer Tammy Beaumont is gone. The Welsh Fire captain lofts Lucy Higham down the ground and picks out one of the two fielders outside the ring - it's Kate Cross and she barely has to move to take the catch.
Victory in this game for either side doesn't yet guarantee a place in Sunday's final - that depends on the result between Southern Brave v Manchester Originals tomorrow.
But taking the bragging rights into the Eliminator - if it ends up being between these two - could be a big confidence-booster.
Tammy Beaumont and Sophia Dunkley make their way to the middle, and to take you through the chase, here's Mike Peter.
While we wait for the chase to get going though, check out this bit of brilliance from Fire spinner Claire Nicholas off her own bowling.
It's a competitive score and it'll take a very good chase from Welsh Fire to get there.
They have already made scores of 165, 144, 181 and 161 in the competition so far - but those have all come from batting first so this will be a different challenge.
Kelly was supported by Phoebe Litchfield's classy 40, with a wicket each for Alex Hartley, Freya Davies, Sophia Dunkley and Claire Nicholas.
