Oh my word, that's HUGE from Peter Trego.

Middled!
Steven Davies gets down on one knee and slog sweeps Samit Patel over mid wicket for a big six.
He finishes the over by ramping him down to the fine-leg boundary.
Davies is motoring.
Somerset 47-2published at 7 overs
Davies 28, Trego 15
Hello Peter!
Ish Sodhi drops one short and Trego flat bats it for six over the leg side.
Oh, that's a chance though. Next ball Trego punches it back at the New Zealand spinner but he can't cling on with his left hand.
It was only a half chance to be fair.
'No margin for error'published at 18:56 British Summer Time 24 August 2017
Somerset 37-2 (6 overs)
Stephen Moore
Former Lancashire opener on BBC Radio 5 live Sports Extra"There's really no margin for error on this pitch. Harry Gurney barely strayed off his line in that over and Peter Trego was able to pick him off easily for a four down to fine leg.
"Notts will be very happy with that powerplay though if this game goes the way people think it will in terms of being very high scoring."

Davies 25, Trego 8
That eases a bit of pressure on Peter Trego.
Harry Gurney sends one onto his pads and the experienced all-rounder clips him behind square for four.
Somerset have only scored 37 in the Powerplay though - someone is going to have to play the innings of their life here to give the visitors a chance.
200 is about a par score at Trent Bridge.

TrentBridgeTally: Jake Ball's 1st ever T20 maiden for Notts - the1st this season and only the 17th all time
Lovely stats there. Thanks!
Somerset 29-2published at 5 overs
Davies 23, Trego 2
That's a gorgeous cover drive from Steven Davies.
Jake Ball strays slightly in his line and Davies cracks him to the fence.
Somerset are finding a boundary an over, but not much else at the moment.
That will need to change shortly.

Davies 18, Trego 1
While Steven Davies is still there, Somerset are in with a chance of a big score.
The left-hander cuts Dan Christian's first ball away to the point boundary - super shot.
But it's another tight one from Notts, just six come from it.

Davies 13, Trego 0
What an over first up from Jake Ball - a double-wicket maiden.
He finishes it off by firing down the stumps, but Peter Trego has made his ground.
Notts are rampant.

Peter Trego confidently plays Jake Ball's hat-trick ball to the off side.
As you were.
'Perfect start from Ball'published at 18:41 British Summer Time 24 August 2017
Somerset 17-2 (2.3 overs)
Jack Brooks
Yorkshire seam bowler on BBC Radio 5 live Sports Extra"No feet movement at all there from Johann Myburgh and a perfect start here for Jake Ball and Notts.
"You try not to lose more than three wickets in the powerplay as a rule and to lose two in two balls is pretty concerning."
WICKET Myburgh (c Moores b Ball) 0published at 2.3 overs
Somerset 17-2
And another! Johann Myburgh chops his first ball behind. Jake Ball is on a hat-trick!
It's a terrible shot first up from the Somerset number three, but a good low catch from Tom Moores behind the stumps.
Peter Trego will face the hat-trick ball...
WICKET Gregory (b Ball) 3published at 2.2 overs
Somerset 17-1
Gone! Lewis Gregory's middle stump is rocked back by England paceman Jake Ball.
The stand-in Somerset skipper tries to give the bowler the charge, but misses. Ball doesn't.
Terrific bowling from the 26-year-old.
'He didn't hit that that hard'published at 18:38 British Summer Time 24 August 2017
Somerset 17-0 (2 overs)
Jack Brooks
Yorkshire seam bowler on BBC Radio 5 live Sports Extra"Beautiful pick-up there from Steven Davies. He didn't even try to hit that shot that hard and it ended up 12 rows back in the stands.
"The results between these two sides historically, the highest score's been 180-odd, so it's amazing there's not been a 200+ plus score between them. Hopefully tonight's the difference."

Gregory 3, Davies 13
You can't bowl there at Trent Bridge.
Left-armer Harry Gurney strays onto Steven Davies' pads and the opener flicks him over mid-wicket for a maximum.
There was also a flick to the fine-leg boundary - 14 off the over.
Somerset 3-0published at 1 over
Gregory 2, Davies 1
As so often happens in T20 cricket, the spinner keeps things tight in the first over.
Samit Patel concedes just three singles.
Great set of six from the big lad.
