Jennings hit 88 (58) for Durham
Notts & Yorkshire beaten in semi-finals
Durham 91-5 (13 overs) v Northants
Close. So close to a spectacular catch by Richard Levi.
Ryan Pringle scoops Ben Sanderson to short mid-wicket, the big South African leaps like a salmon but can't cling on with one hand.
Great effort though.
Durham 90-5 (12.4 overs) v Northants
Chris Woakes
England all-rounder on Test Match Special
"That's been the story of the day. Paul Collingwood hasn't got hold of that and he's been caught on the rope. You get a partnership and lose wickets and build again.
"The pitch isn't bad by any means but wickets have been falling at crucial times and team has to rebuild when the scores haven't been as big as we would have liked."
Durham 89-5 (12.3 overs) v Northants
That's unbelievably bad timing to lose a wicket and it's the Durham skipper Paul Collingwood.
The 40-year-old pulls Ben Sanderson to the leg-side but he doesn't get all of it and Steven Crook holds on inches from the rope.
Durham 89-4 (12.2 overs) v Northants
This has been some knock from Durham opener Keaton Jennings.
The youngster brings up his first ever T20 half-century off 40 balls with a hook off Ben Sanderson and then a single.
Durham 84-4 (12 overs) v Northants
Hmm, that could be a game-changer. Keaton Jennings slices Steven Crook straight back to him, but the seamer can't cling on.
It was a pretty simple chance.
Durham 79-4 (11 overs) v Northants
Wow. That's massive from Keaton Jennings.
The Durham opener decides enough is enough and biffs Graeme White over mid-on for six.
If the Jets are going to post anything competitive here, he surely needs to stay in for the majority of this innings. Jennings is up to 42.
Durham 68-4 (10 overs) v Northants
We have a boundary! It's the first in 33 balls - Keaton Jennings scooping Steven Crook down to fine-leg.
Another eight off the over and 68 have come off the first 10. Not bad, but not brilliant.
Durham beat Yorkshire by seven runs
Catch up on Durham seamer Mark Wood's spell of 4-25 in the second semi-final against Yorkshire.
Durham edged out Yorkshire by seven runs to book their place in the final.
Durham 60-4 (9 overs) v Northants
We're going to be seeing plenty of that over the next few overs with Paul Collingwood and Keaton Jennings at the crease.
The boundaries have dried up, but eight still come from off-spinner Graeme White's first over thanks to ones and twos.

Durham 52-4 (8 overs) v Northants
What's a good score for Durham from here? I guess they'd be happy with 140 right now. Actually, they'd probably bite your hand off.
Durham 49-4 (7.3 overs) v Northants
Oh my word, that's a disaster for the Jets. Coming back for a third run, Azharullah hurls the ball into the wicketkeeper and Jack Burnham is about six inches short.
They need to keep their heads out there. Paul Collingwood is the new man in, just the batsman you need in a crisis. And it is a bit of a crisis.
Durham 43-3 (7 overs) v Northants
Durham are really struggling here. Has the quick turnaround affected them more than Northants? They only had about 20 minutes to compose themselves after that dramatic win over Yorkshire.
Keaton Jennings is still looking composed - he's 17 not out.

Ex-England batsman on BBC Test Match Special
"It's another big blow for Durham but I've always liked the look of Jack Burnham.
"From what I've seen he's scored some runs this year in the County Championship and he's one for the future.
"He needs to dig his side out of a hole now and add some impetus and momentum to Durham's innings."
Durham 43-3 (6.3 overs) v Northants
I'll be honest, I missed the wicket as I was distracted by a bunch of huntsmen chasing a fox in the Eric Hollies stand. As you do.
However, what I can tell you (from a replay) is that Michael Richardson nicked Steven Crook behind and Durham are in all sorts of trouble.
Durham 40-2 (6 overs) v Northants
Two overs from the Steelbacks' Azharullah, six runs conceded. Top, top T20 bowling.
Just four come off his second and that's the end of the Powerplay. Northants just about shading it I'd say.
Durham 36-2 (5 overs) v Northants
Ebony Rainford-Brent
Ex-England player on BBC Test Match Special
"Rob Keogh has taken two match-changing catches, the first was Andre Russell [against Nottinghamshire] but this was a different kind of catch and it was hit pretty hard.
"Ben Stokes was lining up and he got too 'hoiky' on it - but I think he got excited, he saw the length and he got his hands through."
Durham 36-2 (5 overs) v Northants
Durham have a bit of rebuilding to do here you feel after the wicket of Ben Stokes.
Keaton Jennings could be the key. He's 11 not out.
Durham 34-2 (4.2 overs) v Northants
Oh Ben Stokes, what have you done? The England all-rounder cuts his fourth boundary off the first ball of Ben Sanderson's second over, but then pulls him into the hands of Rob Keogh the very next.
It was another fine catch from Keogh on the boundary, but a poor shot from Stokes.
Durham 30-1 (4 overs) v Northants
Big Ben Stokes can smash three boundaries off Rory Kleinveldt, that's what he can do.
The first, a slightly mistimed pull through mid-wicket followed by a slash through point.
His third - stand and deliver over Kleinveldt's head. 13 off the over, big one for the Jets.
