Lancashire v Kent 260-5
James Anderson brings himself back into the attack at Blackpool.
He gets a bit of the inside of Ben Compton's bat but it deflects harmlessly away from the stumps.
Essex 296 v Hants 73-2
Well batted Fletcha Middleton.
Unperturbed by the two wickets to fall at the other end, the Hampshire opener moves to his half century with a delightful flick through midwicket.
Worcs 209 v Surrey 132-1
Dom Sibley's had enough of all this prodding and poking and belts Fateh Singh into the Basil D'Oliveira stand for a maximum.
Surrey are in complete control of this.
Warwickshire v Somerset 431-5

BBC Sport from Edgbaston
Knowing Tom Banton, he definitely still fancies the 450 here.
He won't back down even if he has to fall on his sword trying to get there.
And although Archie Vaughan has still been opening when playing for Taunton St Andrews CC occasionally or for Somerset 2s of late, he was pretty positive first time down the order when he had 80 at seven v Sussex at Taunton last month.
He is looking to run most balls.
Two overs left to get 19 runs now.
Notts 422-8 v Yorkshire
Liam Patterson-White has ticked along nicely today with Ishan Kishan and Dillon Pennington attacking from the other end.
He moves to 50 from 82 balls.
Nottinghamshire have now added 124 runs this morning, putting themselves in an excellent position.
Durham 38-0 v Sussex 361
We have got a pause in play while the ground staff repair a couple of the boundary sponges sporting those sponsor names at the Riverside.
Never had this sort of issue with a good old rope or, if you're a club cricketer, spacing out those wooden blocks painted white before play started.
I believe they call it progress...
Notts 416-8 v Yorkshire
Dillon Pennington defends the fifth ball of O'Rourke's over before swatting another huge six over square leg.
24 runs off the over and Pennington moves to 35 from just 17 balls.
Yorkshire are toiling.
Worcs 209 v Surrey 116-1
The first innings deficit is under three figures.
Dom Sibley has added 21 runs to his overnight 12 not out and he looks like he's settled in for a long stint at New Road.
Worcestershire lost two quick wickets just before lunch yesterday, they need Surrey to do likewise.
Lammonby c Davies b Bamber 133 (Warwickshire v Somerset 425-5)
In pursuit of this final batting bonus point Tom Lammonby perishes for his career best first-class score.
Hit clean but straight to skipper Alex Davies at mid off, who juggles of course glove-less today, but takes.
Warwickshire could get a second bowling point here now.
Notts 406-8 v Yorkshire
Dillon Pennington has come out with real intent for Nottinghamshire and he smashes Will O'Rourke for consecutive fours before heaving a mighty six over the leg side.
O'Rourke is being made to look very ordinary by the home side's number 10.
The fourth delivery of the over is also dispatched down the ground for four more.
Durham 34-0 v Sussex 361
The first runs off Jofra Archer come with a boundary punched off the back foot by Emilio Gay to the point fence.
Gay defends a couple and then flicks one away to the square leg rope for four more runs.
That's his third over bowled - he's been used to bowling four in the IPL.
Warwickshire v Somerset 424-4
This 450 might be on!
Tom Lammonby dabs Che Simmons through third man for four via an Ollie Hannon-Dalby misfield and a collision with Tom Banton as they thought they'd have to run.
Then pulls the Barbadian-born seamer for four between deep square and deep fine leg.
Two singles to finish, 10 off it. Four overs, 26 runs needed for the fifth batting point.

Durham 25-0 v Sussex 361
Sussex are going through their bowling options and we have the spin of Jack Carson.
Alex Lees smacks him straight down the ground for four with his first ball and to follow it up hits a six with the second delivery.
What were we saying about Sussex keeping it tight (12:23 BST)?
Durham 15-0 v Sussex 361
Successive maidens for Jofra Archer on his return - right on the mark.
It will be interesting to see how long John Simpson gives him for this opening burst.
Abell c Yates b Rocchiccioli 48 (Warwickshire v Somerset 407-4)
Tom Abell gets a little carried away though.
After 17 off the first five balls of the over (4, 1, 4, 4, 4) he tries to pull over Rob Yates at midwicket.
A man with 371 in his first first-class knock of the season comes in now!
Harry Came and skipper Wayne Madsen have brought up their 100 partnership for Derbyshire in Bristol, both notching 60no so far.
At 196-2, Derbyshire have already sauntered past Gloucestershire's first innings total of 187 and it looks a long way back for the hosts.
Northants, chasing Middlesex's imposing first-innings 413, are 46 without loss, with Luke Procter (32no) leading the way.
Durham 15-0 v Sussex 361
It has taken eight overs but Durham have the first boundary of their innings with Alex Lees controlling a shot well to guide it away for four runs.
This Sussex attack have bowled tightly and are giving very little away.
We do have sunshine in the North East now after a few spots of rain earlier this morning.
Warwickshire v Somerset 407-3
Tom Lammonby is unfurling his full repertoire now with Somerset cruising to that fourth batting bonus point.
Corey Rocchiccioli is reverse swept for four then takes a single, allowing Tom Abell to match him with consecutive boundaries off the overseas offie.
Lancashire v Kent 240-5
It's slow going in Blackpool where those two early James Anderson wickets seem a lifetime ago.
Kent have really parked the bus, to use a non-cricketing term - they scored just 17 runs from the first 13 overs this morning and while that rate is creeping up, it's still safety-first stuff.
Yet to claim a batting point as well, of course, although that is surely a formality with 250 not far off.
