Durham 296 v Derbys 283 & 398-8
Hilton Cartwright finishes with 71 not out as Billy Godleman decides to call his troops in at Chester-le-Street.
It means Chris Rushworth (4-62) misses out on the chance of a five-for, but the Durham seamer will hope he can put his feet up for the rest of the day.

Sussex 588-9 dec v Leics 607-4
Sean Hunt drops short and Colin Ackermann helps it on its way for four to reach the first double century of his career off 315 balls.

Flat pitch at Hove it may be, but this is still an innings of real substance, demanding skill and concentration.
The partnership with Wiaan Mulder is now worth 328.

Well, that's a disappointment. Hope this won't be a long interruption.
Renshaw c & b Morley 12 (Lancs 642-9 dec v Somerset 446 & 23-1)
Breakthrough for Lancashire - and it's left-arm spinner Jack Morley who achieves it!
Morley, who was asked to complete Will Williams' over when the seamer cut his finger, has stayed on and persuades Matt Renshaw to come down the pitch and drive one straight back into his hands.
Tom Lammonby heads to the wicket with Somerset still trailing by 155...
Yorks 521 & 80-3 v Surrey 515

Kent 335 v Northants 303 & 317-6
If Kent thought that early wicket would open the door to bowling the visitors out quickly, they've been mistaken.
Luke Procter announced his arrival with a series of boundaries to reach 22 not out, but he's now dropped anchor somewhat, while Ryan Rickelton has moved on to 111 at the other end.
Northamptonshire now lead by 285.
Briggs c Brown b Abbott 25 (Hants 370-9 dec v Warwicks 217 & 243)

Danny Briggs tries to take his bat away from Abbott's fifth delivery but a thin edge is taken by keeper Ben Brown.
Hampshire will need to score 91 to win the game.

Sussex 588-9 v Leics 581-4
Image source, Rex FeaturesWiaan Mulder comes down the pitch and hits Steven Finn back over his head for four.
Not satisfied with that, he repeats the shot and this time it brings him six and takes him to 150 off 201 balls.
A square cut for four follows in the next over, bowled by Delray Rawlins, and Mulder and Colin Ackermann now have a 300 partnership
Notts 40-2 - target 455
Two successive half-volleys from James Harris, two fours for Ben Slater. Easy pickings for the Notts opener, who is now 26 not out at Sophia Gardens.

Hampshire 470-9 dec v Warwicks 217 & 237-9
Warwickshire can't just survive at the Ageas Bowl, they have to score runs as well and there are four of them as Danny Briggs produces a nicely-played sweep off Liam Dawson. The lead is now 84.
Lancs 624-9 dec v Somerset 446 & 16-0
A steady start for Somerset's opening pair Matt Renshaw and Steve Davies as they look to bat out the draw.
At the moment, their concentration has been interrupted, with Lancashire seamer Will Williams receiving treatment after somehow cutting his finger midway through his third over.
Not sure about the updated list of substances that aren't permitted on the ball, but blood could well be among them!
Hill lbw Overton 38 (Yorks 521 & 73-3 v Surrey 515)
Image source, Rex FeaturesGreat bowling by Jamie Overton, who produces an inswinging, yorker-length delivery and George Hill can't get the bat down in time.
That's 3-10 from eight overs now - do the Division One leaders scent a possible victory, with Yorkshire only 79 in front?
Notts 28-2 - target 455
Nice shot by Joe Clarke, who greets a half-volley from James Harris with a well-timed, well-placed cover drive for four. Ben Slater is 18 not out at the other end.
Hants 370-9 dec v Warwicks 217 & 221-9
Keith Barker to George Garrett. Will the Hampshire all-rounder complete a five-for and finish off the innings?
Not in this over.
Garrett takes a single to escape the strike and three dot balls to Danny Briggs bring it to an end.
An extension of the England and Wales Cricket Board's broadcast partnership with Sky Sports means The Hundred will be played until at least 2028.
