Somerset 130-4 - target 150
One of the more bizarre shots you'll see from Somerset's Tom Banton...
He plays the sweep off Jack Carson, misses it entirely but then catches the ball with the back of his bat on the way through as it swings round behind his body.
It flies into the off side and he's able to pick up a single.
Down to 20 needed for the hosts...
Somerset 126-4 - target 150
Somerset skipper Lewis Gregory has moved onto 70 but more importantly, the hosts are just 24 runs away from their second win of the season.
They should get this done tonight now you'd think.
Surrey 512 v Yorkshire 255 & 170-6 - trail by 87 runs
Surrey are convinced they've got another but the umpire is unmoved.
There's a big noise as Nathan Smith's delivery passes the bat of Matthew Revis on the way through to Ben Foakes.
Not sure if it was a nick, nor if it carried to Foakes.

You feel Sussex's bubble has probably burst.
It's a flat wicket, we should get over the line now.
The winning line is getting closer.
Hartley c and b Lloyd 2 (Lancs 458 & 137-6 v Derbys 314)
All happening late on at Old Trafford!
What a catch that is!!!!
Tom Hartley punches back down the ground and David Lloyd takes off cat-like to his left to take a wondrous one-handed catch with his left hand in front of non-striker Matty Hurst.
This game is getting intriguing. The lead is 281 and George Balderson joins the fray.
Durham 664 v Notts 407 & 48-1 - trail by 209
Woah! Codi Yusuf bangs in a short ball which takes off like a tennis ball over the head of Rob Lord and the slip cordon. Four wides.
Where did that come from? Five from the over.
Brydon Carse has been bang on the money and returns for his fourth over.
Ben Slater takes a single from the first ball and usher the nightwatchman through to do his job. He does.
Three overs to go.
Surrey 512 v Yorkshire 255 & 169-6 - trail by 88 runs
Matthew Revis defends the hat-trick ball from Tom Lawes but Yorkshire are on the ropes now.
Three wickets lost in three overs and from looking like a draw was a possibility, they now need to just try and survive the rest of day three.

Jordan Buckingham is looking at his bat as he walked off, a golden duck.
Things have changed very quickly indeed.
It was right on the money from Lawes.
ul Hassan c McManus B Sanderson 2 (Glamorgan 2-1 - target 66)
Zain ul Hassan is caught behind and Glamorgan have lost an early wicket!
It's a very low target but they won't want to make to too nervy by losing many more.
Buckingham lbw b Lawes 0 (Surrey 512 v Yorkshire 255 & 169-6 - trail by 88 runs)
Golden duck for Jordan Buckingham and Tom Lawes is on a hat-trick!
It's full, fast and straight and smashes Buckingham on the front pad plumb in front.
Somerset 117-4 - target 150

Lewis Gregory has held this together really well.
All these runs are crucial at this stage.
Bell c and b Morley 2 (Lancs 458 & 134-5 v Derbys 314)
George Bell cuts Jack Morley square for a single and Matty Hurst picks up one more to go to 40.
And then Bell chips a ball straight back to give Morley a simple catch and a third wicket! It's also his fifth of the match.
Tom Hartley joins Matty Hurst with the lead on 278. The game is moving quickly.
Nineteen balls to go.
Hill c Roy b Lawes 0 (Surrey 512 v Yorkshire 255 & 169-5 - trail by 88 runs)
How the tide can turn so quickly in a game of cricket...
Yorkshire have been making a real nuisance of themselves this evening but two wickets in less than 10 minutes have put Surrey well and truly in the driving seat.
Tom Lawes finds George Hill's outside edge and Jason Roy takes a sharp catch at first clip.
Big celebrations from Surrey.
Somerset 115-4 - target 150
Tom Banton and Lewis Gregory keep rotating the strike with singles for Somerset and it's frustrating for Sussex.
It's now just 35 runs needed for the hosts.
Durham 664 v Notts 407 & 41-1 - trail by 216
Brydon Carse so nearly has two in an over as he fizzes one past Rob Lord's outside edge.
Too good for thee.
Four overs remain.
Surrey 512 v Yorkshire 255 & 167-4
Mark Church
BBC Radio London commentator
It swung back very late, it looks like a bit of reverse, they've been working on that ball.
Wharton saw it and all of a sudden it hit the off stump - a lovely piece of bowling.
It was a good partnership, it took a great piece of bowling, he was looking very solid.
Hameed b Carse 13 (Durham 664 v Notts 407 & 41-1 - trail by 216)
A snorter from Brydon Carse as Durham make a big breakthrough.
Haseeb Hameed carried his bat for a double century first time around and has been on the pitch for almost three full days.
But he's beaten for pace as the England bowler knocks back the off stump and goes wheeling off in celebration.
Good luck Rob Lord.
Wharton b Fisher 67 (Surrey 512 v Yorkshire 255 & 167-4 - trail by 90 runs)
A well-deserved wicket for Matt Fisher who has toiled to no avail this afternoon... until now!
The ball has just started doing a bit in the past few overs and it's an excellent, full in-swinger from Fisher.
It has to be good to beat the solid defence of James Wharton today and it is.
Wharton goes for a very good 67 and it's a blow for Yorkshire.
Somerset 111-4 - target 150
Tom Banton is at the crease with Lewis Gregory for Somerset. He made an astonishing 371 in the opening game draw with Worcestershire.
He's not had too many knocks of note since then so he'll want to contribute to a potential victory here. He's onto four.
Wells b Morley 50 (Lancs 458 & 126-4 v Derbys 314)
Fifty and out!
Luke Wells goes for a big shot. And misses. Jack Morley turns one through the gate and the opener falls.
A second wicket for the spinner. George Bell is in with the lead at 270.
