It's pouring it down.
Lancs 158-8 (require 25 from five balls)
This game is a ball away from being up for Lancs.
Migael Pretorius has the ball in hand and has given up a four with his first delivery.
Hartley c Kohler-Cadmore b Green 0 (Lancs 152-8 require 31 from 10 balls)
And that is what happens when you try to be too clever by half.
Tom Hartley is subbed in for George Balderson and then goes first ball, straight down long off's throat.
Lancs 152-7 v Somerset 182-7
Michael Carberry
Former England batter on BBC Radio 5 Sports Extra
I can't understand that decision.
And I feel sorry for Balderson. He was doing fine and had a chance to win a game for his club.

It's gone so dark. Are they going to finish this innings before the heavens open?
Balderson retired out 7 (Lancs152-7 require 31 in 11 balls)
George Balderson has been subbed (retired out) with Tom Hartley coming on for the final hits.
Not sure about that.

As if Lancs didn't have it tough anyway with half a team missing, then you get a decision like that. Some finals day. Farce.
Tim
Lancs 151-6 (require 32 from 12 balls)
Jake Ball has bowled a very good over with pace off very much on the menu.
He has mixed it up and George Balderson can't quite time anything perfectly with just seven off it.
Michael Jones is on strike and this, you feel, is the match.
Lancashire need 183 to win
Mark Davis
Former Somerset seamer on BBC Radio Somerset
Somerset are still not in control because of that no-ball six and the free-hit six. The wicket is important but so is the dot ball and it brings a new batter in. It's not easy for a new guy to come in and strike straight away.

Michael Carberry
Former England batter on BBC Radio 5 Sports Extra
If anyone is going to get Lancashire up here, Michael Jones has to be the man now.

Just to add to the drama... it's about to rain at Edgbaston.
Blatherwick c Overton b Pretorius 15 (Lancs 142-6, require 41 from 20 balls)
Looked like a six when it left his bat but he has not timed that.
It was a low full toss but Jack Blatherwick has not quite got hold of it and it goes high to midwicket where Craig Overton makes a big shout and takes the catch.
Somerset are back in control.
Lancs 141-5 (require 42 from 22 balls)
Michael Jones hits a big one over long off and, better news still, it is a no ball and a free hit.
And what do you know... the free hit sails for a second six over backward square leg.
Is that the momentum shifter?
Lancs 126-5 (require 57 from 24 balls)
Michael Jones and Jack Blatherwick have a huge task on against a hugely experienced Somerset death bowling attack.
Jake Ball fires a loose, wide full toss but Blatherwick can't quite get enough elevation on the cut towards the point boundary.
Just a single and the buzz is going from the crowd.

You can just see the start of a spike in the frame before the ball passes the bat. Quite clearly the spike after was too large to just be pad. Really poor decision from the third umpire
Richard
To say the contact with the inside edge is between frames is not good enough. That could be crucial in this game and the tech should be good enough to make sure the decision is definitely right.
Andy in Warrington
I don't agree with the third umpire's logic that there was a definite gap between bat and ball. But ultimately it was the right decision - there isn't conclusive evidence either way to overturn the decision.
Jack
Lancs 119-5 (require 64 in 30 balls)
That is more like it.
Jack Blatherwick has swung at one in the slot from Ben Green and heaved it over wide midwicket for six.
A few more would be handy.
Lancs 110-5 v Somerset 182-7
Michael Carberry
Former England batter on BBC Radio 5 Sports Extra
Keaton Jennings and Liam Livingstone are the only two batsman to get the pace of this pitch for Lancashire.
But Somerset have been outstanding in the field so far.
Shetty c Gregory b Green 6 (Lancs 110-5 Target: 183)
Arav Shetty reaches for a widish ball and dobs Ben Green to cover where Lewis Gregory takes a tumbling catch to his left.
The oomph is leaving this Lancs reply and the run rate is climbing. They need over 13 per six now.

The ball also changes direction slightly after the ball passes the bat. Livingstone has every right to be upset. That's an absolute horrendous decision.
Seb, Winchester
DRS showing there why I’ve always thought Hotspot is the more reliable technology… UltraEdge is just far too unreliable and subjective.
Russ, Upton
Sat in front of Lancs dressing room. Massive smash as Livingstone went into the dressing room! A few ‘choice’ words too…
