Durham 153-8 v Northants 4-2 (1.2 overs)
Wow. A complete calamity at the start of this Northants innings.
Josh Cobb edges Mark Wood along the ground towards Ben Stokes at slip, Stokes parries it to Scott Borthwick who pings the ball at the stumps and Richard Levi is run out with a direct hit.
And now it's starting to rain.
Durham 153-8 v Northants 4-1 (1.1 overs)
Mark Wood is on fire!
The England and Durham paceman finds a bit of extra bounce with his first ball and Adam Rossington can only fend it to Scott Borthwick at slip.
Pace. Sheer pace.
Durham 153-8 v Northants 4-0 (1 over)
Edgbaston is now looking resplendent as the floodlights take full effect against an increasingly dark and moody sky.
But no threat of rain I'm pleased to report.
Chris Rushworth bowls an excellent first over. Just four from it.
Durham 153-8 v Northants 0-0
I barely had time to grab a coffee and they're back out there!
Richard Levi and Adam Rossington to open for Northants, Chris Rushworth to bowl the first over for Durham.

Northants face a target of 154
That man was Keaton Jennings.
While wickets tumbled around him, the opener mixed correct shots with some huge blows to make 88.
The numbers - 58 balls, five fours and four sixes.
Will it be enough to give Durham their first Twenty20 title?
The Northants chase starts in seven minutes.

Former West Indies fast bowler on Test Match Special
"It is a competitive total from Durham and they will take that given the atmosphere and the pitch and Northants' bowling power.
"If Durham get some early wickets and get into Northants' batsman early then you never know, I've seen funnier things happen in cricket."
Durham 153-8 (20 overs) v Northants
Durham can't quite get to 160 as Azharullah does what Azharullah does and bowls a full length to restrict the Jets to just nine off the last set of six.
But a fine effort to get there after they were 49-4 in the eighth over.
And that's down to one man...
Durham 144-8 (19 overs) v Northants
So, into the last over. Azharullah to bowl it.
160 would be marvelous for Durham and their fans - who don't forget have a mammoth journey home this evening!
Durham 144-8 (18.5 overs) v Northants
Another one goes. Scott Borthwick has a wild swing but can only nick Rory Kleinveldt behind.
Durham 139-6 (18 overs) v Northants
Ebony Rainford-Brent
Ex-England batter on BBC Test Match Special
"[Keaton Jennings] should be proud he's come out today on Finals Day and he hit straight and accelerated Durham through that innings.
"If Durham are able to use his score in the last few wickets then they could storm to finish."
Durham 140-7 (18.1 overs) v Northants
Oh, what a shame. We won't be seeing our first ever T20 Finals Day century.
Keaton Jennings, who deserved three figures, swipes Rory Kleinveldt into the leg-side, but straight into the hands of Josh Cobb who holds onto a simple catch.
He's given Durham something to defend though. Breathtaking innings.
Durham 139-6 (18 overs) v Northants
Well batted Keaton Jennings.
He now has the best score at a Finals Day, surpassing the 86 made by Gloucestershire's Craig Spearman in 2007 and Darren Maddy for Leicestershire the year before.
Just 12 needed for a century. Two overs to get them.
Durham 132-6 (17 overs) v Northants
This is getting ridiculous now. But incredible to watch.
Keaton Jennings doesn't quite middle it but gets enough on the ball to send Rory Kleinveldt sailing over long on for another maximum.
He then leans back and plays him over backward point for four.
16 off the over and Jennings needs just 15 for a fantastic hundred.
Durham 116-6 (16 overs) v Northants
Straight. As. An. Arrow.
Keaton Jennings is fighting a lone battle for Durham out there.
The opener pings Steven Crook back towards the sightscreen for the straightest six you will ever see.
That's three for the South African born batsman who is onto 70.
Durham 105-6 (15 overs) v Northants
Chris Woakes
England all-rounder on Test Match Special
"He's got a habit of taking worldies on television, has Josh Cobb. He did that down at the quarter final against Sussex when he caught Mahela Jayawardene.
"He's done it again on the big occasion here and tonight it's crucial."
Durham 105-6 (15 overs) v Northants
Ben Sanderson finishes his spell with 3-31.
Terrific from the Northants quick.
Durham 104-6 (14.4 overs) v Northants
You won't see a much better catch than that.
Ryan Pringle bludgeons Ben Sanderson towards cover, but Josh Cobb dives high to his left and plucks the ball out of the air.
That's T20 cricket at its best.
Durham 103-5 (14.2 overs) v Northants
Keaton Jennings smashes his second maximum of the innings, swiping Ben Sanderson over the ropes at square leg.
Superb hitting from the 24-year-old who moves up to 61.
Durham 95-5 (14 overs) v Northants
Super over of spin from Graeme White. He concedes just four off the 14th.
Six to go. Can Durham get to the magic 140 mark?
