Somerset score 151-6
Jake Ball tells Sky Sports about his stunning catch:
"Alex Hales came up to me and said 'he's [Peter Trego] is very unlucky to be out there!
"Looking at the scores throughout the year it's 200 par. To keep them to 150, we're really happy with that.
"Hopefully our batters can chase them down."
Van der Merwe 27, Overton 15
Well, Somerset will have something to defend, but is it enough?
They only hit four boundaries in the last eight overs - that says it all really.
Harry Gurney finishes the innings by conceding just five.
If Alex Hales tees off for Notts, this could be done and dusted pretty quickly.

"That last shot slightly blights Jake Ball's over, but still tremendous figures from the England seamer.
"Depending on how this game pans out, that could be the match-winning spell."
Ball finished with 2-21 off his four overs.

Roelof van der Merwe and Craig Overton are striking it well but can't find the boundary off Jake Ball.
Eventually Van Der Merwe skews it away for four and ends up on his backside.
Somerset are going to end up with a below-par score here. They'll need to bowl out of their skins to make Finals Day.
Van der Merwe 18, C Overton 9
Wow, that's an absolute stinker from Harry Gurney.
The seamer bowls a high full toss at Roelof van der Merwe which he skews high into the air and is caught by the wicketkeeper. But it's a blatant no ball.
Van der Merwe misses the free hit. Somerset need to go big in these final couple of overs.

Somerset have to keep going for their shots. 140 or 150 is unlikely to be enough on this ground.
Paceman Jake Ball returns and keeps it tight. No boundaries.

"You have to feel Somerset are setting themselves up here rather than Notts taking the game away from them.
"There's been a series of poorly executed cricket shots from the batsmen."

Somerset 118-6
Somerset are in real strife now.
Michael Leask dances down the track but can only swipe Samit Patel into the big mitts of Steven Mullaney at long on.
Craig Overton comes to the crease. He can hit a long ball.
Van der Merwe 8, Leask 0
Michael Leask is the new man in for Somerset.
He averages 12.5 with the bat in T20 cricket. Somerset have a pretty long tail, so that wicket is even more of a concern.

Jack Brooks
Yorkshire seam bowler on BBC Radio 5 live Sports Extra
"He tried to work it over the boundary there and didn't get enough on the ball.
"Stephen Davies and Peter Trego have given Somerset a platform, but after losing three quick wickets, it's hard to see where they'll go from here.
"They need to get up to 150-160 at least."
Somerset 114-5
Oh no, what have you done Steve?!
Steven Davies steps across his stumps and flicks Dan Christian into the leg side, but straight into the hands of Alex Hales on the rope.
That could well be the game changer.
Davies 59, Van der Merwe 2
It's all going on out there.
Steven Davies tries to go for a single, slips in the middle of the wicket, but just about makes his ground.
He finishes Samit Patel's over with a lovely reverse sweep for four. Davies is the key here.

Image source, Rex Features"Hell of a catch from Jake Ball there in the previous over. Taken on the move with a bit of a dive.
"Notts needed that wicket of Peter Trego desperately. James Hildreth failing to get all his bat on the ball the following over and it's a leading edge right back to Samit Patel."
Somerset 102-4
James Hildreth is gone first ball. It's a huge blow for Somerset.
He tries to clip Samit Patel into the leg side, but gets a leading edge straight back to the spinner.
It's an easy chance and Patel gobbles it up. The visitors have lost two in two.
Davies 50, Trego 38
Image source, Rex FeaturesHere they go.
Peter Trego rocks back and swipes Steven Mullaney to the rope.
14 from the over. Somerset are on course for a good score.
Somerset 88-2
Image source, Rex FeaturesThe Somerset opener moves to his half-century off 33 balls, the delivery after smashing Steven Mullaney for a big six into the leg side.
It's been a brilliant innings so far from the former Surrey man.
Davies 43, Trego 32
Image source, Rex FeaturesDan Christian has bowled a super over there.
The Australian mixes up his lines and pace and concedes five from it with no boundaries.
Notts needed that.
Davies 41, Trego 30
Image source, Rex FeaturesOh, that's a horrendous misfield from Brendan Taylor.
Peter Trego cuts Steven Mullaney away and it goes right through the Zimbabwean.
Good over from the medium pacer mind - just six from it.
Somerset 69-2 (9 overs)
Stephen Moore
Former Lancashire opener on BBC Radio 5 live Sports Extra
"There's a nice little partnership here for Somerset that's setting the foundation for them.
"You really feel that one of these two has to go deep in the innings to give them a great chance of going through to the Finals."
Image source, Rex FeaturesDavies 40, Trego 25
That six from Peter Trego was 96 metres by the way.
Ish Sodhi fights back well for the rest of the over however, conceding a couple of singles and a two.
Trego is ticking.
