Fire post 161-4 with Dunkley making 86, Beaumont 40 and Matthews 38
Munro takes 2-24
Spirit won the toss and bowl
Welsh Fire will secure knockout place if they avoid defeat
Fire 108-2
Consecutive fours from Sophia Dunkley off the bowling of Sarah Glenn, driving her through the covers before finding the leg-side boundary. She brings up the hundred with a single to long-on.
The England batter is looking very well set here.

Remember when we thought spinners would just get hit out of the game in white-ball cricket? Bowlers like Rashid prove their worth time and time again.
J Overton c Carse b Rashid 2 (Originals 158-5)
Four wickets for Adil Rashid!
The leg-spinner ends a magnificent spell with a wicket as Jamie Overton hits back down the ground but into the hands of Brydon Carse at long-off.
Buttler c Brook b Rashid 75 (Originals 156-4)
Jos Buttler's fun is over, he's caught at deep mid-wicket.
He skipped down to Adil Rashid but aimed his shot towards the longest boundary on the ground.
The timing and power were never quite there and Harry Brook takes the catch.
Buttler walks off to a standing ovation but looks frustrated with himself.
Buttler 75, Holden 9
Six!
Jos Buttler gets hold of this one. He was waiting for the short ball from Reece Topley and sends it flat over square leg for his third six.
The ball before he skied but somehow it landed safely as three fielders converged trying to take the catch.

You know it is your day when shots like that are falling in between fielders.
Is this the start of Jos Buttler's late charge?
He tries to hammer the ball over the leg side, doesn't time it and the ball goes a long way up...
...but into the gap between the fielders. One bounce for four.
Jos Buttler brought up his fifty with a big six but we're still waiting for the big explosion from him late in the innings...
Fire 91-2
Sophie Munro has the breakthrough and how! Two wickets with her first two balls.
A floating, full slower ball befuddles Tammy Beaumont and clean bowls the England opener. Munro follows that up by finding the edge of new batter Laura Harris. The umpire's finger is raised, Harris sends it upstairs immediately but there's a sound on snicko.
Hayley Matthews sees off the hat-trick ball with a four past backward point.
That boundary aside, it's a decent set from Callum Parkinson.
He's finished with figures of 1-31 from 20 balls.
Jos Buttler has the strike with 15 balls left.
Great shot from Max Holden!
He dances down the track to Callum Parkinson, gives himself a bit of room and cracks the ball through extra cover for four.
A wicket for Adil Rashid, his second of the day, and just five from that set.
The last of them is a single for Jos Buttler, though, so he'll keep strike with 20 balls left in the innings...
Walter st Banton b Rashid 28 (Originals 129-3)
Adil Rashid makes the breakthrough!
The Superchargers spinner saw Paul Walter coming, pushed the ball a bit wider, it was the googly as well so the ball spins even further past the bat.
Walter was nowhere near it with the big swing and Tom Banton did the rest.
Adil Rashid will bowl the next five. If anyone can slow the Originals down, you'd think it would be him.
Fire 75-0
Spirit are still in search of a breakthrough as Fire openers Tammy Beaumont (40) and Sophia Dunkley (28) accumulate steadily.
No boundaries in these 10 balls, with Fire slowing down somewhat outside of the powerplay.
Buttler 57, Walter 28
Flicked leg side for a single by Paul Walter and Northern Superchargers call for a strategic timeout.
They have got plenty to discuss with Jos Buttler and Walter starting to motor.
It's Paul Walter's turn this time.
He's quickly down and nails the slog-sweep over mid-wicket into the Party Stand!

200 could well be on the cards here.
Long hop from Matthew Short and Jos Buttler rocks back and lifts the ball over the leg side for six!
He made that look incredibly easy but that is not a particularly short boundary.
Originals 113-2
Smashed over long on for six! Jos Buttler goes to his half-century in style.
He gets there from 35 balls and looks ready to kick on again with 30 balls left in the innings.
