Notts 487 & 64-0 v Yorkshire 510
The players could shake hands now at Trent Bridge.
Ben Slater and Haseeb Hameed are cruising along at more than five an over on this flat pitch.
Warwickshire 56-2 (target 377) v Somerset
Two slips and a short leg in for Archie Vaughan who causes problems straight away.
The spin twins in tandem now just 15 overs into this fourth innings.
Warwickshire 52-2 (target 377) v Somerset
Sam Hain is playing far more positively in this innings interestingly.
I am not sure yet whether the chase is on so to speak, but it is odd that he did not do this to get what could have been easy batting bonus points in the first innings.
He shuffles and hits Jack Leach for six straight.
Archie Vaughan to bowl from the City End now.
Sussex 218-4, lead Durham by 252

Unmitigated levels of excitement may break out as the new ball has just been taken in CLS.
The old one has been unceremoniously booted off the field. And good riddance to it. It's been utterly dull today. Credit to the batters, who have not lost a wicket, but this is enough to get cricket done away with.
The Kookaburra gives the bowlers about a 15-over window when it's new and that's about it. 20 overs if lucky. And if it gets wet you've had it.
I hope this experiment is abandoned next year, when we have whatever structure to the county season they decide. Sadly there's still three rounds of games to go with it this season.
Ben Raine had a big appeal for LBW against Danial Ibrahim (75) with the first delivery of the new ball, but it was not given. John Simpson has 63. Batting has been extremely straightforward though, on a slow, flat track.
Not sure what will come first? A wicket, or me falling asleep!
Warwickshire 44-2 (target 377) v Somerset
Jack Leach appeals, he is giving Sam Hain pain with his arm balls particularly, but not given.
Hain sweeps for four next ball as Leach gets too full and onto his pads.
Warwickshire 40-2 (target 377) v Somerset
Craig Overton is not at all happy with Sam Hain's time wasting.
Neither are the crowd, with many Somerset fans still here after the short trip up the M5 Sunday morning.
Oohs and aahs from the crowd are ignored by Hain who just tickles one off his hip and Overton neglects the chance to bump nor sledge him as Hain runs past him.
Essex 296 & 234-5 v Hants 453
Michael Pepper and Tom Westley continue to accumulate nicely for Essex, frustrating the Hampshire bowlers and increasing the probability of a draw.
Essex lead by 77, with Westley on 87 and Pepper on 71.
Durham 327 v Sussex 361 & 214-4
A final throw of the dice from Durham as they take the new ball.
Sussex lead by 248 runs.
Ben Raine hits the pads of Danial Ibrahim with his first ball with the new cherry - not out.
Lancs 639-9d v Kent 374 & 90-5
Chris Green (4-32) is bowling with seven fielders around the bat plus wicketkeeper Matthew Hurst.
If Joey Evison or Jaydn Denly fancy a chat then they won't be short of company.
Evison sweeps for four runs.
Kent trail by 175 runs.
Lancs 639-9d v Kent 374 & 86-5
Chris Green's hat-trick ball at the start of his next over is safely negotiated by Joey Evison.
Two batsmen are going to have to play very well to deny Lancashire a first red-ball win of the season.
Warwickshire 30-2 (target 377) v Somerset
Craig Overton brings himself on to replace Matt Henry after five overs.
Jack Leach may be plugged in for the session from the Pavilion End whilst Somerset seamers rotate from the City End.
Lancs 639-9d v Kent 374 & 84-5
Oh, almost another wicket with the first ball of the very next over.
Jaydn Denly fends at one off Mitchell Stanley and it falls just short of the man at gully.
Kent are wobbling.
Leaning c Wells Green 0 (Lancs 639-9d v Kent 374 & 84-5)
Chris Green takes two in two balls.
He gets Jack Leaning caught at bat-pad by Luke Wells and Kent are crumbling.
Green has four wickets but will have to wait for his hat-trick ball until his next over.
Joey Evison is next in - Kent still trail by 181 runs.
Warwickshire 24-2 (target 377) v Somerset
Sam Hain is taking his sweet time between balls, already irritating the Somerset fielders, there could be a fair amount of gamesmanship across the rest of this match this afternoon.
61 overs to go, Henry and Leach the only bowlers used thus far.
Muyeye c Jenning b Green 3 (Lancs 639-9d v Kent 374 & 84-4)
Same combination, same result.
Tawanda Muyeye goes forward to Chris Green and Keaton Jennings takes a fine catch by getting his fingers under the ball just off the ground.
Three wickets for Green now.
Kent trail by 181 runs.
Durham 327 v Sussex 361 & 202-4
A nice job done by Danial Ibrahim and his captain John Simpson.
They came together at 111-4 when the game could have rapidly gone south for Sussex but they're now batting their side towards a well-earned draw.
Sussex lead by 236 runs.
Lancs 639-9d v Kent 374 & 82-3
Lancashire want the wicket of Tawanda Muyeye as he tries to pull a ball from Mitchell Stanley.
It keeps low and goes through to Matthew Hurst.
Was there a touch? No sir.
Nervy moments for Kent just as with the early stages this morning.
Kent trail by 183 runs
Yates b Leach 13 (Warwickshire 16-2, target 377 v Somerset)
Jack Leach has Somerset a second inside six overs here!
Rob Yates bowled by an absolute peach flicking his off bail.
Sam Hain in far earlier than he would have wanted, but at least he is right handed, so the footmarks should be less of an issue for him.
Hain had 78 off 170 balls in the first dig, will he be more positive in this innings to attempt the chase or will they try and shut up for the draw early?
Gloucestershire declared their second innings at lunch on 526-6, setting Derbyshire 316 for victory. They've got off to a flier - 26-0 off three overs.
Glamorgan are almost level with Leicestershire as Sam Northeast and Colin Ingram's fourth-wicket stand continues to grow. They've put on 183 to take Glamorgan to 219-3, and they trail by just four runs.
Northants, chasing 311 to beat Middlesex, have lost opener Ricardo Vasconcelos to Toby Roland-Jones. The hosts are 27-1 at Wantage Road.
Notts 487 & 17-0 v Yorkshire 510
Yorkshire don't look particularly like running through Nottinghamshire's batting line-up in this second innings.
Jack White starts with a few wayward deliveries down the leg side, one of which skips away for four byes and leaves Jonny Bairstow with a sore hand.
Dan Moriarty takes the new ball from the other end and is carved to the fence twice by Haseeb Hameed.
