Tuesday's matches: Spirit v Phoenix women (15:00 BST) & men (18:30 BST)
Timothy Abraham and Tom Mallows
Josh Cobb larrups Sam Cook down the ground for six off the final ball of his next set. 13 runs taken off five balls. Cobb going to go down in a blaze of glory.
83 runs from 25 balls is the equation for Welsh Fire.
It's a big ask.
Not much to write home about in this Welsh Fire innings but Ben Duckett did hit a nice six a little earlier.
Welsh Fire skipper Josh Cobb survives, foot clearly behind the line.

Josh Cobb doesn't look particularly worried.
Tom Moores has the bails off again. Tabraiz Shamsi had tossed one up and Josh Cobb had attempted to go big.
It's been taken upstairs.

The spin of Samit Patel and Tabraiz Shamsi has been outstanding. Two very canny and experienced operators.
Matt Critchley thwacks Samit Patel back over his head, into the night sky. A couple of bounces and that's four.
Patel is bowled out as he finishes with 2-23. He has a big grin on his face. That's 10 wickets in this year's tournament.

That one turned viciously into Leus du Plooy. It was fired in but gripped and knocked back the off stump. The bails light up and Samit is off celebrating.
Du Plooy b Patel 2 (Fire 81-5)
Leus du Plooy deploys the wrong shot against a vicious bit of turn from Samit Patel. Du Plooy was attempting to push it on the back foot but it's quicker and it bowls him. Patel is a cock-a-hoop.
The pitch looking trickier to bat on.

The boot comes off once more! That is a huge wicket in the context of the game as David Miller was just showing signs of getting going.
Miller c Cook b Shamsi 5 (Fire 78-4)
South African David Miller is Welsh Fire's next batter, up against his international team-mate and you can guess who has ended up with the bragging rights here.
Miller attempts to smash Tabraiz Shamsi but does not quite make clean contact and is caught by Sam Cook to send the Rockets spinner wild.
Shamsi reels out his trademark celebration of taking his boot off and placing it to his ear to make a phonecall.

Ben Duckett tried to hit it over the top of mid-off but that's good catch from Colin Munro diving forward.
That's a big blow for Welsh Fire as he really has been the man in form for them this year.
Duckett c Munro b Shamsi 25 (Fire 72-3)
Tabraiz Shamsi gets the man he really wants a couple of balls later.
Duckett takes the aerial route but slices the shot but a fine diving catch by Colin Munro gets rid of Fire's top runscorer this year.
Shamsi roars in celebration.
Yep, that's glove. Matt Critchley survives.

Matt Critchley is indicating to Ben Duckett that it has come off his glove.
Tabraiz Shamsi to Matt Critchley, and it hits him on the pad. Given out on field, but he's immediately reviewed this one.
Woah, woah, we're halfway there. Welsh Fire very much livin' on a prayer.
102 off 50 balls required to win this one.
