Northants enforce follow-on after bowling out Gloucestershire for 268
Leus du Plooy hits century for Middlesex against Worcestershire
Lancs 143-2 - target 424
Lancashire keep scoring runs and this time it's Marcus Harris hitting Matt Parkinson for four.
Harris is five away from 50 and the home side now need 281 runs to win.
It's getting into doable territory.
Lancs 139-2 - target 424
Kent think they've got Keaton Jennings but the umpire doesn't agree.
Jennings tries to reverse sweep from Bertie Foreman and it's not clear whether it hits bat or pad.
It was mighty close to lbw if it was pad and the ball loops up for slip to take a catch, so if it was bat, it would have been out caught.
Durham 377 v Derbys 118 & 206-5
A flurry of fours at the Riverside, but not all of them convincingly played.
After Harry Came clips Matthew Potts through mid-wicket, Ben Raine sends one down which keeps very low but Martin Andersson manages to squeeze it down to third man off the outside edge.
Boorman c Vasconcelos b Weatherall 15 (Northants 465 v Gloucs 268 & 84-2 (f/o))
Northants move another step closer.
Raphy Weatherall gets a ball to seam away and catches the outside edge of Tommy Boorman's defensive push.
You can't fault the batter, he had to play at it. Good ball.
Miles Hammond joins Cameron Bancroft so plenty of experience out there for the visitors.
Middx 339 & 115-4 v Worcs 265
That one could be a key moment. Leus du Plooy, who scored 85 in the first innings, edges Ben Allison to slip.
It's a sharp chance for Ethan Brookes but he'll be disappointed not to have hung on.
Du Plooy is on 27 and Middlesex lead by 189.
Durham 377 v Derbys 118 & 198-5
So close.
Harry Came dangles the bat at a ball from Matthew Potts and adds four runs to fine leg via the inside edge.
He moves on to 94 not out.
Northants 465 v Gloucs 268 & 83-1 (f/o)
Image source, Getty ImagesThere are some things in life you can rely on and a Cameron Bancroft contribution often tends to be among them.
He plays Harry Conway through midwicket for a couple and that moves him to a 52nd career first-class half-century off a spritely 69 balls.
It’s been a lovely mix of anchoring the innings while putting the bad ball away.
The 33-year-old has a good knack of converting those scores, too - he has 33 red-ball hundreds.
How Gloucestershire could do with a 34th right now.
Lancs 134-2 - target 424
Keaton Jennings sweeps fine down the legside from Matt Parkinson and comes back for two to reach his 50 in 95 balls.
That's a fifth half-century of the County Championship season for Jennings.
Notts 193 v Somerset 310 & 185-5
Somerset score a run. Been a little while since we've said that.
It's Thomas Rew who gets it, nudging a single to mid-wicket from Lyndon James.
London buses and all that... Archie Vaughan then gets off the mark from his 23rd ball, flicking off his legs and the Somerset pair push for three.
And from the final ball of the over, Thomas Rew drives through the offside and it flies backward of square for four.
Sussex 521 v Glamorgan 155 & 145-2
Jaydev Unadkat is back for Sussex and that's a well-timed cover drive by Ben Kellaway, which brings him four runs and takes his score into double figures.
Yorkshire 469 & 69-3 v Warwickshire 263
Will Luxton is a batter in form. Having more than doubled his career best with 167 in the first innings, he's added a half century in the second.
He gets there pulling Hannon-Dalby and nearly holing out to Beau Webster.
Luxton's batted confidently having clearly been boosted by his earlier efforts and he's helped push Yorkshire's lead to 279.
They'll want that to rise to at least 400 before
Notts 193 v Somerset 310 & 177-5
Archie Vaughan bats out a maiden from Liam Patterson-White and is still yet to get off the mark after 22 balls.
Kelly lbw b Porter 19 (Leics 187 & 166-4 (f/o) Essex 401)
Another big blow for home hopes.
Nick Kelly plays around a Jamie Porter delivery which has a little extra nip and wraps him on the back pad.
It's bang in front, going on to hit middle and leg, and the first innings dangerman goes for 19.
Joey Evison joins Lewis Hill.
Lancs 129-2 - target 424
Matt Parkinson goes up for a very enthusiastic appeal after spinning it into Keaton Jennnigs and catching him on the pads but it's hitting a long way outside the line of the stumps.
Leics 187 & 166-3 (f/o) Essex 401
More width from Simon Harmer and Nick Kelly gets down low to cut him square for his first four. He's up to 13.
Kelly top scored in the first innings with 78 and steps down the wicket and whips th spinner wide of long on for a couple more.
The deficit is down below 50 - 48 more to make Essex bat again.
Lancs 127-2 - target 424
Not really a dropped catch but Marcus Harris is slightly lucky as he takes an edge off Bertie Foreman and it flies past slip for four.
Keith Dudgeon gets a fingertip to it but it would be harsh to call that a drop.
Durham 377 v Derbyshire 118 & 192-5
We enter a crucial passage of play at Chester-le-Street.
Derbyshire are still 73 behind as Ben Raine takes the new ball.
Undaunted, Harry Came steers behind point for four to enter the 90s.
Matthew Potts will presumably be called on at the other end, needing one more wicket for a five-for.
Wharton lbw Hannon-Dalby 5 (Yorkshire 469 & 67-3 v Warwickshire 263)
Olly Hannon-Dalby, who started his professional career at Yorkshire many moons ago, gets one to nip back at James Wharton and has him lbw.
Will Luxton (48 not out) is the only batter who's looked comfortable.
Yorkshire now lead by 273. At their current scoring rate they could be 400 ahead with about an hour to go today.
Notts 193 v Somerset 310 & 177-5
Archie Vaughan doesn't seem in a hurry to get off the mark. He's seen off 13 balls so far as Liam Patterson-White continues with spin for Notts.
Northants 465 v Gloucs 268 & 75-1 (f/o)
Tommy Boorman plays a classy shot for four through the offside to spoil Liam Guthrie's hopes of a maiden from his sixth over. It takes him to nine.
Cameron Bancroft then picks up a single off Harry Conway to move within a couple of his fifty.
