Liam Dawson comes into the attack and we'll see some spin for the first time.

Ricardo Vasconcelos and Nathan McSweeney pick up a couple of respectful singles to rotate the strike and can't quite time the ball off the bat and have to settle for two more singles, despite a collision in the field.

Strangled appeal from Dawson for leg before against Vasconcelos as he tries a sweep but it was always outside leg and Dawson finishes with a dot ball.

Five off the over. Vasconcelos has 32* and McSweeney is 29*.

Hampshire taking Chris Lynn's wicket early on felt significant for them but there has been no let-off in the Northants batting levels.

Ricardo Vasconcelos and Nathan McSweeney have played some absolutely delightful shots in this powerplay, this has been brilliant to watch so far.

Sonny Baker is the latest Hawk to misjudge one at short fine leg as Nathan McSweeney pulls Chris Wood away for another four to move into the 20s. Wood can't be too grumpy, he did the same to Baker moments ago.

A couple of singles follow before McSweeney pulls another one bounce four to long leg.

61-1 at the end of the six-over powerplay. A fine recovery after the early loss of Chris Lynn.

Ricardo Vasconcelos picks up a single to bring up the Steelbacks 50 at the start of the sixth over, bowled by Chris Wood.

Scott Currie into the attack for Hampshire and Nathan McSweeney digs out a yorker from his second delivery for a single.

Ricardo Vasconcelos then produces a glorious straight drive for a one-bounce four, holding the pose in textbook fashion.

He carves another to backward point from the penultimate ball of the over and then wallops the final ball through mid-wicket to make it three boundaries in the over and take the left-hander to 27* from 18 balls.

Nathan McSweeney pulls another rapid ball from Sonny Baker to fine leg but a scrambling stop saves two runs.

Chris Wood is deceived by the next ball as it is whipped towards him at short fine leg but beats his stoop and races away for four.

McSweeney digs a 91mph yorker out, via the inside of his ankle, and scampers a single to get out of the firing line for a moment.

Ricardo Vasconcelos glances a single to Wood to tack on another one before McSweeney ramps a glorious six over fine leg to bring the crowd to their feet.

Chris Wood caught ever so slightly on his heels.

I think that’s a missed chance.

Ricardo Vasconcelos picks up a couple off the first ball of Chris Wood's second over, and then drives uppishly down the track two balls later, finding the rope, but only via the fingers of the bowler.

Another boundary follows from the fourth ball, hoisted over midwicket to the fence, and a single along the deck brings Nathan McSweeney back onto strike to splay one to deep point for a quick two.

Good response by the Steelbacks to the early disappointment.

Sonny Baker finishes his over with a 92mph delivery to new man Nathan McSweeney.

He has his tail up good and proper...

Lynn gone in single figures is the perfect start for the Hawks.

Chris Wood opens proceedings with a wide which swings away late, with Ricardo Vasconcelos on strike.

Vasconcelos clips a couple to deep mid-wicket and punches sweetly through the covers for another two, but it's just five off the opening over.

Here we go then, it all comes down to this...

The side batting first have won both semi-finals but Hampshire have opted to chase and it's Chris Lynn and Ricardo Vasconcelos who head out to the middle to face the opening over from Chris Wood.

Of the 23 previous finals, the winner of the second semi have won 14 titles, with just nine winners coming from the opening game of the day.

Another good omen for the Hawks as they chase an unprecedented fourth title?

Chris Lynn is the man of the tournament so far and he’s back to take down Hampshire.

But Northants bat so deep. All the way down.

They’re a brilliant outfit and this will be a very tough final.

A final deserves to be the platform for the top players and we will have two of three best performers both with the bat and the ball when Hampshire meet Northants later.

Joe Weatherley's unbeaten 88 against Notts Outlaws in today's semi-final means he has now made 516 runs in this year's tournament, behind only Warwickshire's Beau Webster who totalled 578.

Chris Lynn was a big part of Hampshire's run to last year's final but will come up against his former side having made 39 in the low-scoring semi-final win over Somerset and averages more than 50 this year to stand third in the list of run makers with 514.

Scott Currie may not get the top headlines but his 24 wickets for the Hawks have been key to their success with his two in the last four taking him within three of Yorkshire's Hasan Ali who leads the way.

Northants James Sales proved his worth by taking 1-16 from his four overs against Somerset and he has 23 wickets in the Blast this year.

Will these four have a big say on where the silverware goes this evening?

The players are on their way to the middle for the final...

As one of the smaller counties on the circuit, it's very easy for Northamptonshire to slip under the radar.

But in the last two seasons under grizzled ex-Australia head coach Darren Lehmann, the Steelbacks have started to punch above their weight again.

They returned to Finals Day last year for the first time in nine years only to lose to Hampshire Hawks in the semi-final, when a certain Chris Lynn smashed an unbeaten 108 - the first Finals Day century.

But they were impressive winners of the Central and West Group this season and posted the best record in the group stage with nine wins, the first eight of them in succession, then saw off Gloucestershire in the quarters with a bit to spare.

Australian T20 specialist Lynn has smashed two centuries in his new colours, while James Sales and Calvin Harrison have now combined for 43 wickets with the ball.

Northants have reached Finals Day for the sixth time and the second consecutive season, the last time they did that in 2016 they won the second of their two titles, three years after their first.

Nottinghamshire Outlaws head coach Peter Moores said:

“No complaints. Credit to Hampshire, they outplayed us on the day. Joe Weatherley played really well, it was a good partnership with James Vince. We actually did pretty well to hold on, because at one point I thought they were going to get 200.

“Par for the pitch is about 175 so they were a bit over, but we thought we had a good chance of chasing it. It was not far from where we wanted to be at the halfway stage, but then suddenly they got the rate up to where they wanted it to be.

“We needed someone to have a cameo in the back half, but it got a bit tricky, we picked a few out, but they bowled well.

“Joe Clarke played really well. He’s had a tough tournament actually, but he’s got better and better. Jack Haynes didn’t quite get going, but he’s done it - we are here because of what he did in the quarter-finals. We then needed somebody to get 30 or 40 off 20. We would have been right in the hunt then.

“Hampshire did things pretty well. They fielded well, it was a good partnership for their platform. They have some good hitters, we did well to hold on to it because it could have got really messy. We got ourselves in the frame, but we didn’t quite get the cameo in the back half.”

It's a mightily quick turnaround from the second semi-final to the final, so we're just getting some reaction from losing Notts Outlaws coach Peter Moores...
