Phew.

So Somerset will hang around for tonight's final.

And we'll shortly see who of Kent or Sussex will join them.

Toss coming up in a moment.

T20 cricket is all about momentum - a few balls can change a game from over to over.

And what we saw there was Ben Green and Craig Overton - with three sixes out of nowhere, that's what got them back in that game and with the chance to win it.

What an incredible win from where they were.

Josh Davey is man of the match. He tells Sky Sports:

"It was an emotional rollercoaster but we're so glad to get over the line.

"We were behind the game but we have a lot of batting."

4-34 for Davey with the ball and then 11 from just 3 balls.

Somerset captain Lewis Gregory speaking to Sky Sports:

"What a game to start Finals Day.

"Both teams batted poorly in general but those last three overs were pretty special to watch.

"I thought they were under par but they still got 15 more than they should have."

I'm speechless. Hampshire will be devastated that they have lost the game from that position.

Somerset have hung on, they have stayed in the game as long as possible, took it as deep as possible and been able to get over the line at the last minute. And they did it with a couple of overs to spare as well.

Three or four overs ago, there was no way they were going to win that game.

Hampshire captain James Vince speaking to Sky Sports:

"It's a deflated dressing room.

"Joe Weatherley played so well to give us a score and then all went to plan with the ball up until the final three overs.

"It can be a cruel game T20. We didn't execute right at the end there."

Utterly remarkable.

Times have Somerset's lower order got them out of trouble in the Championship but it's done the job in the shortest form here.

And how.

Unbelievable stuff from Ben Green and then Josh Davey.

56 from the final 22 balls!

How on earth have Somerset won that game of cricket??

When Tom Abell went in the 17th over they were absolutely gone.

Can you believe it?

Josh Davey flicks it over midwicket and Somerset have got up to win!

Field comes up because a tie is good enough for Somerset.

High, ho, long, yes!!!

Josh Davey pumps one over long-on for six!

It just clears the fielder on the fence.

Somerset were down as low as 3% with the Win Predictor at one point.

Craig Overton back on strike but a great yorker is only dug to long-on for one.

Low full toss flicked leg side just for one to deep midwicket.

It's taken a while to get going today - and it could still go either way - but those three Ben Green sixes have got the crowd going.

It's getting closer to full now, it's noisy, tense and the Crusaders, boy scouts and things in orange bibs are bobbing up and down in the Hollies Stand.

Josh Davey on strike.

Brad Wheal - who closed out the quarter-final at Trent Bridge - to try and see this out too.

Craig Overton takes two off the final ball and it leaves 10 needed from the final over.

Oh my!

Another full toss and it's swung over midwicket!

Somerset beginning to get up now!

Ben Green on fire.

Oh wow Ben Green goes again!

A half-volley from Chris Wood and it's disappeared over square leg.

What are Hampshire doing here?

Another leg side heave and it doesn't quite carry to the fielder in the deep.

Could James Fuller have got there? He did! Dropped catch and two runs.

Low full toss outside off and it pushed wide of deep cover for two.
