J Taylor c Sales b Guthrie 12 (Northants 465 v Gloucs 268 & 179-6 (f/o))
Liam Guthrie has a seventh wicket of the match as Gloucestershire suffer another blow.
The left-armer bangs one in short and Jack Taylor can't resist, falling into the trap as he pulls it straight to James Sales on the deep backward square boundary.
Gloucs six down still trailing by 18.
Sussex 521 v Glamorgan 155 & 240-6
Poor ball from Sean Hunt and Chris Cooke thumps it away over square leg for a maximum. The Glamorgan deficit comes down to 126.
Notts 193 v Somerset 310 & 327-7
Jack Leach has raced along to 20 off 15 balls, guiding a clever up and over the 'keeper off Mohammad Ali for four.
Notts 193 v Somerset 310 & 322-7
Hello, Thomas Rew, this time!
Rew pulls a massive six over mid-wicket from Mohammad Ali. First the new-ish ball and now the replacement new ball both taking a battering.
Maybe Somerset are having a couple more overs to pile on as many as possible before declaring.
Leics 187 & 267-5 (f/o) v Essex 401
Ben Cox overtakes his partner Lewis Hill as he hits Charlie Bennett square through the onside for his sixth boundary.
He is just four short of a very valuable half-century.
The partnership is up to 83 and the lead passes 50.
Notts 193 v Somerset 310 & 316-7
How much longer before Somerset declare? Surely they've got enough runs now? The lead is 433.
Sussex 521 v Glamorgan 155 & 236-6
What a great leaping catch by Jack Leaning (or was it a great leaning catch by Jack Leaping?).
It counts for nothing, though, as that was a no-ball from Sean Hunt to Chris Cooke.
Notts 193 v Somerset 310 & 314-7
Hello, Jack Leach!
Huge six off Dillon Pennington, smashing it through the legside and that's damaged the ball after smashing into a brick wall.
Somerset are 431 runs ahead.
Yorkshire 469 & 198-5 v Warwickshire 263
George Hill completes his third championship half century of the season.
While doing so he's helped take Yorkshire's lead beyond 400.
It's just a case of waiting to see when Jonny Bairstow declares.
Northants 465 v Gloucs 268 & 178-5 (f/o)
It's safety first for Gloucestershire but there's a rare attacking shot as James Bracey drives Liam Guthrie straight down the ground for four.
Lovely shot.
It moves the wicketkeeper to within six runs of his fifty and the deficit down to 19.
Moores c Benjamin b Mahmud 0 (Lancs 233-6 - target 424)
Hasan Mahmud has a five-for on debut and perhaps Kent are closing in on victory now!
Two wickets in three balls for the visitors as Joe Moores tries to tickle down the legside but is caught behind by Chris Benjamin.
Now the 189 runs Lancashire still need looks like an extremely tall order.
Sadly, Warwickshire haven't turned up for this match. They really lack consistency in their top 4 batsmen. Time for Ian Bell to come out retirement.
Prit, Harpenden
If you asked him, what do you think he'd say?
Yorkshire 469 & 192-5 v Warwickshire 263
Zen Malik has taken a couple of excellent catches at short leg but he had no chance with a full blooded blow straight at him from Jonny Bairstow.
After some treatment Malik is ready for the next ball,
Notts 193 v Somerset 310 & 301-7
Image source, ShutterstockA maiden first-class century for 18-year-old Thomas Rew in just his second County Championship match for Somerset!
Rew pushes towards the covers and there's a misfield, allowing him to race through for a single.
He gets there from 135 balls. Well done, young man.
Livingstone b Mahmud 47 (Lancs 233-5 - target 424)
Just how vital could that wicket prove to be for Kent?
Just three runs short of a 50, Liam Livingstone is bowled by Hasan Mahmud.
Livingstone tries to pull hard through the legside but bottom edges and drags onto his own stumps.
Mahmud has four wickets of the five in this innings and now seven in the match. Great debut for the Bangladesh seamer.
Notts 193 v Somerset 310 & 300-7
Thomas Rew is playing it calm still despite being on 99. He blocks a couple of length balls from Brett Hutton.
Notts 193 v Somerset 310 & 300-7
Jack Leach takes a very quick single to mid-off for Somerset off Brett Hutton and that brings up the 300.
The lead is 417.
Northants 465 v Gloucs 268 & 172-5 (f/o)
Liam Guthrie beseeches the umpire to give a wicket as he finds the front pad of James Bracey.
Nothing doing - it looked to be clearly going down the legside.
Quiet start after tea, Gloucestershire have added four runs after the break.
Notts 193 v Somerset 310 & 299-7
Thomas Rew moves to 99*, nudging a single to mid-wicket off Brett Hutton.
He's now just one away from that maiden first-class ton.
We'e already had one result, with Durham completing an innings and 22-run win over Derbyshire at the Riverside.
Matthew Potts took 8-66, for match figures of 10-97, and he said: "It’s been quite a frustrating year, so to do that and get the rewards out there for the hard work of the winter and pre-season is really rewarding.
"Our goal is to get back in Division One. We were probably sub-par last year and let ourselves down at the back end of the season.
"We’re well on the way. The job’s not done, but performances like that as a team stand you in good stead."
Head coach Ryan Campbell, meanwhile, confirmed there is a "75%" chance of Ben Stokes playing in their home game against Northants, which starts on Friday. "That’s going to be an interesting selection decision," he added.
