Durham 497-5 v Notts 407
Image source, Getty ImagesOllie Robinson cuts Mo Abbas through point for his sixth boundary and that's a first century of the season for Ollie Robinson.
He punches the air as he raises his bat to the stands.
The Durham wicketkeeper has reached three figures for the 10th time in his red-ball career. This effort has come off 141 untroubled balls.
Flat pitch, fill your boots.
Elgar c Roderick b Allison 22 (Worcs 358 & 134 v Essex 157 & 34-1)
Great ball and Worcs have the first breakthrough!
Ben Allison comes around the wicket and bangs one into the body of Dean Elgar who can only nudge it behind to Gareth Roderick to take the catch.
The ball beat him all ends up there and deserved a wicket.
Essex require another 302 with nine wickets in hand.
Bean c Foakes b Smith 7 (Surrey 512 v Yorkshire 255 & 19-1 - trail by 238 runs)
A wonderful delivery from Surrey seamer Nathan Smith.
He angles it in to Yorkshire opener Fin Bean from round the wicket and gets it to nip back away off the track.
It takes a thin nick and Ben Foakes makes an excellent catch behind the stumps.
Somerset 338 v Sussex 152 & 250-7 f/o - lead by 64 runs
Image source, Getty ImagesSussex have moved to 250 in their second innings.
More importantly, their lead is now 64 runs. Can they keep this going?
Guest b Bohannon 77 (Lancs 458 v Derbys 236-8)
The end looks nigh for Derbyshire's first knock.
Brooke Guest's impressive innings comes to an ungainly end as he aims a big drive at Josh Bohannon but drags it onto his stumps.
Guest chunters away to himself as he trudges off the pitch after a 154-ball innings.
Just a 14th first-class wicket for Bohannon.
Ben Aitchison joins Zak Chappell.
They need 73 more to avoid the follow-on.
Durham 482-5 v Notts 407
Image source, Getty ImagesGraham Clark swats a flighted ball from Liam Patterson-White into the legside for a single and that's fifty.
He becomes the fifth Durham batter to reach a half-century and it must be the quickest. It's come off just 56 balls
Durham 482-5 v Notts 407
Dave Bracegirdle
BBC Radio Nottingham commentator
39 runs from eight overs definitely shows some intent now.
Clark and Robinson are getting a gallop on and their partnership is building.
Notts have been spot on in the field in most of the innings, but there's been a few mis-fields since lunch.
Notts are just gifting them runs and opportunities.
Warwicks 88-3 - target 310
The captain is showing the way for the Bears.
Alex Davies pushes an easy single into the offside to bring up a brisk fifty off 66 balls.
He's struck 10 fours in that half-century - the 44th of his career.
Surrey 512 v Yorkshire 255 & 17-0 - trail by 240 runs
Fin Bean picks up his first boundary of the innings with a lovely on-drive off Nathan Smith. Much more of that required today for Yorkshire.
Somerset 338 v Sussex 152 & 246-7 f/o - lead by 60 runs
That's also a 50 partnership for John Simpson and Fynn Hudson-Prentice.
Captain Simpson is seven away from his 50 and Hudson-Prentice has moved onto 26.
A timely bit of digging in.
Warwicks 83-3 - target 310
Richard Wilford
BBC Radio WM commentator
It's an important innings this for the Bears.
Someone is going to have to go to three figures, the batting conditions haven't been the best.
Alex Davies' half-century will be key for the Bears.
Glos 466-8 v Kent 424
A half-century for Tom Price and maximum batting points for Gloucestershire.
They also lead by 43 so it's all going pretty well you'd have to say.
Somerset 338 v Sussex 152 & 246-7 f/o - lead by 60 runs
Well, you don't see this too often...
Fynn Hudson-Prentice inside edges one off Tom Lammonby and it flies past wicketkeeper James Rew and crashes into the helmet sat behind him for the short-leg and silly point fielders.
That's a five-run penalty for hitting the helmet and a welcome boost for the visitors.
Surrey 512 v Yorkshire 255 & 13-0 - trail by 244 runs
A first boundary of the innings for Yorkshire as Adam Lyth clips one off his legs from Nathan Smith for four before guiding one behind square on the off side for another three.
Surrey 512 v Yorkshire 255 & 10-0
Mark Church
BBC Radio London commentator
I think Yorkshire have to look at this and not worry about tomorrow but worry about today.
They need to keep this scoreboard moving.
Dal c Phillip b Hartley 19 (Lancs 458 v Derbys 219-7)
A tame end.
Anuj Dal looks to cut Tom Hartley but a thick outside edge finds Anderson Phillip at backward point.
Zak Chappell joins Brooke Guest. Derbyshire are back in a hole.
Hain lbw b Abbott 30 (Warwicks 78-3 - target 310)
Kyle Abbott gets a third!
Sam Hain shoulders arms to a ball which jags back in and hits him on the front pad. It would have gone on to hit middle and off.
A promising innings ends. Hants needed that.
Davies b van Beek 1 (Middlesex 232 & 85-6 - lead by 43 runs v Leics 274)
Image source, Rex FeaturesJack Davies is gone for Middlesex and it's looking bleak for the hosts now.
An excellent delivery by Leicestershire seamer Logan van Beek and he clean bowls Davies for just one.
This is turning into a collapse for Middlesex. From 51-0 to 85-6.
Durham 452-5 v Notts 407
Graham Clark drives Brett Hutton down the ground for a single to take Durham to their 450 in the 131st over of a mammoth first innings.
Ollie Robinson and Clark then trade singles to bring up the fifty partnership in 68 balls.
Clark has 33 of them.
Somerset 338 v Sussex 152 & 236-7 f/o
Annie Chave
BBC Somerset
It's interesting, Somerset have got Pretorius, Overton and Henry who haven't bowled yet.
Maybe they're just trying something different, but it's very interesting.
