Phoenix crumble to 22-5 in reply before Elwiss (32) & Wong (24) give them hope
But Ecclestone takes superb 3-8 as Phoenix are bowled out for 104 off final ball
Originals need results go their way and to win final game to progress
Phoenix miss chance to reach knockouts but still well placed
Monday's matches: Rockets v Fire women (15:30 BST) & men (19:00)
This game feels like it is swinging.
A misfield allows Georgia Elwiss to pick up a single and then Emily Arlott muscles the next ball over the ropes for the first six of the Phoenix's chase.
Erin Burns is under pressure all of a sudden.

The two boundaries change the equation again. We were writing them off a couple of minutes ago, but we might be in for a tight finish. It's what this format is all about.
Need 45 from 20 balls
Interestingly Northern Superchargers needed 55 from 25 balls against Manchester Originals last week and they got over the line with one ball to spare. Phoenix needed exactly the same here. Have Originals learnt from their mistakes?
Lovely from Georgia Elwiss as she skips down the pitch and hits down the ground for four, before Hannah Jones fires in five wides down the leg side.
This could be a very exciting finish.

England opener on BBC Radio
It's going to be very difficult now for the Phoenix. They need to hit boundaries, which are really difficult to come by.
Wong st Threlkeld b H Jones 24 (Phoenix 68-6)
It felt like it was coming.
Issy Wong comes down the track, looking to hit the over, but dances past the ball.
Ellie Threlkeld gathers and whips off the bails and Wong is well short of her ground.
Threlkeld has been faultless with the gloves.

A good set from Australia's Erin Burns, conceding just four runs.
Originals are really building the pressure.
Yeah, the throw allows Issy Wong to get back.
Wong's bat did hit Ellie Threlked's boot and come out of the former's hand but she'd safely made her ground before that.

I think she has made it. She had a lot of ground to make up, she has done really well to get back.
Has Issy Wong been run out?
The throw was a bit wayward from Kate Cross so I think her England team-mate may have got back.
This was a brilliant catch from Ellie Threlkeld.
She is a very special talent with the gloves.
Need 59 from 30 balls
Brilliant from left-arm spinner Hannah Jones.
She concedes just three singles and the pressure is really on Phoenix now. The required run-rate is up to almost two runs every ball.
The attendance at Edgbaston is a record for a women's domestic game too.

Manchester Originals captain Kate Cross knows she needs a tight set so she decides to return to the action herself.
She is able to do just that, with just four singles coming from the five balls.
The pressure swings back towards Birmingham Phoenix.
Thea Brookes
Central Sparks all-rounder on BBC Radio
Elwiss just used the pace of the ball and guided it beautifully. She's full of finesse. That relieves the pressure by some margin for Birmingham Phoenix.
Need 66 from 40 balls
Good set for Birmingham Phoenix.
Georgia Elwiss twice finds the boundary, first with a guide through the off-side, before a nice shot back down he ground.
Is the pressure starting to transfer? Originals aren't used to winning so if the game gets tight we might see mistakes sneaking in.
Thea Brookes
Central Sparks all-rounder on BBC Radio
You need to have that fire to run twos. We need to see these a bit more. If you show 100% intent, you'll most often complete the runs.
Phoenix 48-5
No, Georgia Elwiss is home by about a foot.
There was a run-out opportunity from the previous ball too, but the throw went to the wrong end.
Phoenix need 75 from 45 balls.
Kevin Howells
BBC Radio
I think the umpires are going to take a look. I feel she's home comfortably.
Birmingham Phoenix are having to take risks now.
Has Georgia Elwiss been run out looking for a second here?
Hunch is telling me no.
