Somerset skipper Lewis Gregory brings himself on for a bowl and it's a strong first over with just three singles from it.

It was swung away by Chris Lynn and he got just enough on it over deep square for the six.

It was an anxious moment because there was a fielder down there who looked interested for a split second and then realised it was going to clear him by comfortable margin.

Northants 51-3 v Somerset

On comes ex-England spinner Jack Leach to have a bowl for Somerset.

Chris Lynn stretches at one outside off to pick up a single to deep cover and Saif Zaib nudges another one.

Lynn then decides enough is enough and rocks back to smash Leach high over his head for a one-bounce four.

And then he goes one better, sweeping hard for six over deep square leg and the outstretched arms of the fielder on the rope.

Lynn is the danger man for Northants.

Both fielders called for it. But you'd much rather have that than both saying 'yours' or not calling.

Two good fielders (Lewis Gregory and Tom Kohler-Cadmore), they both wanted to take the catch.

Northants are tottering.

Jake Ball is into the attack for Somerset and starts with a very tight over with just the one leg bye from it.

A rare T20 maiden and not a bad time to get one in a semi-final.

That's the end of the powerplay.

Northants 38-3 v Somerset

Chris Lynn is finally able to get in the swing of things for Northants, pulling away deep behind square for four on the legside from Craig Overton.

The very next ball, he smashes another pull but this time it's huge and sails into the stands over mid-wicket.

Lynn ends the over with a low paddle to pick up a single.

Northants opener Chris Lynn finally faces his first ball in the fourth over. He blocks and then nudges Riley Meredith's second delivery for a single to square leg.

David Willey then squirts a fortunate but useful boundary with an inside edge that races away to the rope before picking up a leg bye.

David Willey swipes at one outside off and it runs through backward point.

Willey scampers back for two and the bails are whipped off by Thomas Rew as the throw comes in from the deep but Willey had just about made his ground.

All a bit nervy for Northants here. Just two runs from the over and a wicket lost.

That's two successful appeals from Somerset and two wickets.

Northants will not want to lose a third wicket in the powerplay.

Another huge appeal as Craig Overton strikes Nathan McSweeney in front. Somerset huddle quickly together and are reviewing the not out decision again.

It was really close when looking at it because you could see a little bit of the off-stump exposed.

Nathan McSweeney is in and his first ball from Riley Meredith thuds into his pads.

Northants scamper through for a quick two before McSweeney nudges a single to mid-wicket. A good over for Somerset with the wicket of Ricardo Vasconcelos.

Chris Lynn still hasn't faced a ball yet.

Australian pace bowler Riley Meredith with the second over for Somerset and his first ball is flashed away hard by Ricardo Vasconcelos behind square on the offside for four.

Then a big appeal as Vasconcelos attempts the ramp and is caught at leg slip. Did it hit the bat or was it lbw? Somerset are asking the question.

Nice start for Northants from the first ball as Ricardo Vasconcelos flicks Craig Overton off his legs for four. That should settle any early nerves.

Vasconcelos then walks down the track to the fourth ball and flicks into the legside again to pick up another two.

And then a beautiful stroke for the second boundary of the innings, Vasconcelos pushing through extra cover on the up and it races away for four.

A quick single to end the first over and the Steelbacks will take that.

The pyro show greets the two sets of players as they take to the field and now away we go at Edgbaston for the highly anticipated T20 Blast Finals Day.

Northamptonshire Steelbacks, who have the most wins in the competition so far, against Finals Day regulars Somerset. This should be good.

Somerset's Headingley hero Craig Overton will bowl the first over for Somerset. Ricardo Vasconcelos and Chris Lynn opening up for Northants.
