Fergus O'Neill takes 5-51 for leaders Notts against Hampshire
Yorkshire's Jonny Bairstow and Adam Lyth out for 120 and 141 at Headingley
Olly Hannon-Dalby claims 5-53 for Warwickshire against Glamorgan
Tom Abell and Craig Overton hit centuries as Somerset declare on 526-8 against Sussex
Matthew Potts takes 6-92 for Durham against Kent; Emilio Gay out for nought in reply
Derbyshire's Ben Aitchison follows his five wickets with 112 for Derbyshire at Lord's
Matt Taylor takes 5-36 as Gloucestershire bowl out Northants for 127
Hants 202-9 v Notts
Liam Patterson-White is into the attack for Notts, and he has been dabbed for singles by both Sonny Baker and Brad Wheal in this over - that has seen Hampshire pass 200.
Considering Hants were 85-5 having lost Nick Gubbins yesterday, it has been an admirable effort, led by Felix Organ, to drag themselves up past this milestone.
Somerset 350-5 v Sussex
This may be another mini session. The nearby Quantocks are barely visible in the gloom as Tom Abell and Craig Overton return to the middle.
Tom Clark has four bowls left to complete his over.
Tom Abell on strike - and he's 81 not out.
What a tremendous example OHD is. Start of the season he was deemed surplus to requirements and went out on loan. With Woakes and Barker injured he was recalled. Back he came to take wickets. No speeches he just gets on with it like the true pro he is.
Chris, Hampshire
Hannon-Dalby is one of those highly-skilled, but unsung county pros. He very much deserves your praise, Chris.
I am very worried about Essex. Yesterday the bowling was the worst for ages, today the batting is looking as bad. What is going on?
Stuart, Woodbridge
Odd thing to say perhaps with 430+ on the board but it feels like Kent have thrown this away a bit? Certainly let Durham back in it...
Mark, Herne Bay
Middlesex 177 v Derbys 161-5
Eathan Bosch is leg side to Wayne Madsen, who helps the ball on its way down the slope for four.
He moves to 15 and is starting to move through the gears after a stodgy start.
Three more runs squirted past point, though that wasn't far from Ryan Higgins.
Four more runs tapped into the leg side as Bosch again loses his line.
11 off the over and Derbyshire trail by 16.
Any kind of lead will be handy on this slow, seaming surface.
Kent 450-7 v Durham
Oops. Keith Dudgeon plays too soon at a ball from Kasey Aldridge but it lobs over the head of the fielder at cover and Kent claim their fifth batting bonus point with five balls to spare.
Dudgeon seems to be enjoying himself out there, he carved Ben Stokes over backward point for four in the previous over and is 22 not out.
Yorkshire 429-6 v Surrey
A bit of housekeeping to inform you about - Jamie Smith is not wicket-keeping for Surrey in this morning's session.
Smith damaged his thumb late on yesterday and Josh Blake has taken the gloves today.
Blake is unable to prevent a loose delivery from Jordan Clark going down the leg side to the boundary for four byes.
Dom Bess then clips away very nicely off his pads to bring up the 50 partnership with George Hill.
Middlesex 177 v Derbys 150-5
Ryan Higgins strays to leg and Wayne Madsen picks up four with a clip through mid wicket.
A slight delay as the bowler is in conference with his captain, Leus du Plooy.
Over bowled and Navyaa Sharma (among the England Lions squad v South Africa A later this month) will resume from the Nursery End...
Ben Aitchison drives... and is dropped at cover.
He takes a single and moves on 20.
Madsen gets a single off the last ball of the over and that takes Derbyshire to 150 in 50 overs.
Organ c Veyrrenne b Stone 55 (Hampshire 199-9 v Notts)
Felix Organ's resistance is over.
He looks to play Olly Stone firmly into the off-side, but only succeeds in bottom-edging through to Kyle Veyrrenne behind. It is the first wicket of the innings for Stone.
Kent 439-7 v Durham
In case any of you were wondering about Ben Stokes' state of health after he felt unwell yesterday, he is out there in the field for Durham.
Keith Dudgeon drives Kasey Aldridge through mid-off for four to post a 50 partnership with Ekansh Singh - who is none the worse after his 'ding' on the helmet from Ben Raine - and now we will see Stokes with the ball for the first time this morning.
Yorkshire 416-6 v Surrey
Dan Worrall is back into the attack for Surrey and with the fourth ball of his 20th over he almost finds the outside edge of Dom Bess.
An airy-fairy waft from Bess who is lucky not to nick behind.
Two deliveries later, George Hill crunches a boundary just in front of square.
Hill has looked very assured since arriving at the crease approximately 40 minutes ago.
Glamorgan 360 v Warwickshire (yet to bat)
The innings break is likely to last more than a few minutes here, sadly.
In what are increasingly gloomy conditions, the floodlights are coming on - and so have the covers.
Those in attendance at Edgbaston have their brollies up.
Hadley b Hannon-Dalby 8 (Glamorgan 360 v Warwickshire)
A five-fer for Oliver Hannon-Dalby, who knocks over Aussie quick Ryan Hadley to collect his 14th five-wicket haul for Warwickshire - his first since 2024.
Glamorgan added 19 runs this morning before the conclusion of their innings.
Essex 43-4 v Leics 333
Following that wicket of Tom Westley, Ben Mike's next ball is short and wide outside off stump and Charlie Allison clatters it away for four.
Somerset 350-5 v Sussex
Weather permitting the above applies.
As it stands - seven overs lost.
Westley c Cox b Mike 2 (Essex 39-4 v Leics 333)
Image source, ShutterstockOh dear.
Ben Mike fires a delivery way down leg-side and in trying to glance it away, Essex skipper Tom Westley only succeeds in giving a catch to Ben Cox, diving away to his left.
Great athleticism and anticipation by the Leicestershire keeper.
Middlesex 177 v Derbys 142-5
The pressure is on the hosts somewhat to get into the Derbyshire tail for first innings parity.
Derbyshire captain Wayne Madsen is there but struggling a little with just the one run in near enough 15 minutes of batting.
Navyaa Sharma draws Madsen forward into a play and miss.
He connects this time though and drives for three.
Ben Aitchison is hit on the pad but high up and missing leg.
Good over from Sharma. Derbyshire 35 behind.
Yorkshire 407-6 v Surrey
A delightfully controlled shot from Dom Bess on the hook goes to the leg side boundary for four.
The wickets of Jonny Bairstow and Adam Lyth this morning don't seem to have stopped Yorkshire's rhythm.
Hampshire 193-8 v Notts
There is Felix Organ's half-century, a vital knock in difficult conditions for Hampshire.
He injected a lease of life into their innings in the evening session yesterday with a flurry of boundaries and has been careful and controlled so far this morning.
Hants will hope that Organ and what is left of their tail can eke as many runs as possible out of Notts' attacking before the change of innings.
Thus far Brad Wheal (8*) has looked to score, too.
Essex 39-3 v Leics 333
Image source, ShutterstockJamie Porter throws the bat at a widish one from Ben Green - it's aerial but flashes past the gully fielder and away for four.
Nightwatchman Porter advances to 21 not out and Leicestershire call up Ben Mike for his first bowl of the innings.
Kent 437-7 v Durham
Ouch.
Ben Raine strikes Ekansh Singh on the helmet and we'll have a break while the Kent physio is summoned.
Buoyed up by those three early wickets, Durham look like they 'mean it' this morning.
