Lawrence c Cooke b Norton 8 (Glamorgan 358 v Surrey 16-3)
Brilliant from Tom Norton! Glamorgan are all over Surrey like a rash right now!
Beautiful line, perfect length, and Norton finds the outside edge of Dan Lawrence.
Centurion Chris Cooke takes a regulation catch behind the stumps. What a start for Glamorgan.
Ollie Pope walks out for Surrey. Dom Sibley then plays and misses at a delivery by Timm van der Gugten.
Leics 302-4 v Yorks 185
Dan Moriarty's radar has been awry most of the match and a legside ball gets what it deserved as Ben Cox sweeps for four to go to 15 off 17 balls.
Back-to-back boundaries bring up the second batting point for the Foxes in the 72nd over.
Sussex v Hants 41-5 (lead by 73)
There's not been a wicket in five overs at Sussex - not sure what the bowlers are playing at!
Tom Haines is into the attack for the home side, bowling around the wicket.
Ali Orr (20*) could be the key to this Hampshire innings now.
Somerset 208 v Warks 155-4
Beau Webster escapes again as he plays and misses wide of off-stump at a fired-up Alfie Ogborne.
The replacement for Migael Pretorius is having an impact. But he's now stretching out his leg as he walks a touch gingerly back to his mark.
He then hops uncomfortably at the end of his follow through and then falls on his front in the final ball of his over.
The replacement is now going off for treatment.
Somerset could well do without losing another bowler.
S Curran b Norton 0 (Glamorgan 358 v Surrey 6-2)
Sam Curran is bowled for a duck - Surrey look in huge trouble!
Around the wicket, Tom Norton completely beats Curran all ends up, taking middle and off rather comfortably. Two in the over!
Dan Lawrence and Dom Sibley have a huge job here to hold off this Glamorgan attack right now, they are bang up for this.
Durham 69-3 v Northants 450
Image source, Getty ImagesBen Stokes pulls a Ben Sanderson delivery to the square leg boundary to move to 25 not out.
Stokes and Will Rhodes are scoring nicely as they attempt to rebuild the early damage inflicted by the Northants attack.
Stokes then comes down the wicket to smack Sanderson down the ground - 29 to the England Test captain now.
Hain c Overton b Ogborne 68 (Somerset 208 v Warks 151-4)
Somerset chip out another.
Alfie Ogborne finds extra pace and bounce from the pitch which takes Sam Hain by surprise.
He tries to withdraw the bat, but it catches the edge and flies to Craig Overton who grabs a sharp chance at second slip.
Hain's 157-ball vigil is done.
Both set batters are now out as skip Ed Barnard joins Beau Webster, with the Bears still trailing by 57.
Burns run out Kellaway 6 (Glamorgan 358 v Surrey 6-1)
Incredible! Rory Burns is run out for 6!
Burns is just jogging and doesn't even put his bat down to the ground - what is he thinking here?
Lackadaisical doesn't even cover it. Ben Kellaway's quick direct hit gives him the shock of his life and Burns has to go.
Burns responded at the non-striker's end but barely put in a jog and was out by a mile.
To make matters worse, it looks like Burns is given words by a member of the crowd as he heads up towards the pavilion.
Sam Curran is in for Surrey.
Ahmed c Whiteman b Revis 128 (Leics 285-4 v Yorks 185)
Gone!
One big shot too many for Rehan Ahmed who shuffles back reluctantly to the pavilion after a brilliant 128 from 167 balls.
He looks to drive again but hits Matthew Revis straight to Sam Whiteman.
Ben Cox joins Nick Kelly with a 100-run lead to build on.
Somerset 208 v Warks 147-3
Incredibly harsh to call that a drop.
Sam Hain drives firmly into the air back down the ground and Jake Ball thrusts a hand up in his follow through.
It brushes his fingers and the paceman wrings his hand vigorously afterwards.
It would have been a worldie had it stuck. It saves four runs nonetheless.
Glamorgan 358 v Surrey 4-0
Openers Rory Burns and Dom Sibley walk out to the middle for Surrey.
Burns confidently leaves the first delivery of the innings by Timm van der Gugten.
That one was angling in menacingly but misses the outside of Burns' off stump.
The next delivery is beautifully straight-driven down the ground by Burns for four.
Essex 184 v Notts 250-6
Image source, ShutterstockNotts continue to take this game away from a tired looking Essex.
Jack Haynes (80*) and Lyndon James (21*) are playing positively.
The 250 is up and the lead goes to 66 runs.
Somerset 208 v Warks 146-3
The Somerset squad eschew the usual football warm-up by booting a rugby ball around before heading back on to the field.
A bit of fortune for Beau Webster to the fifth ball after the resumption as a thick outside edge off Alfie Ogborne runs for four down to third man.
The Australian then has to look sharp to jab his bat down and keep out a yorker.
Libby lbw b Williams 29 (Worcs 72-2 v Glos 289)
Will Williams goes bang, bang and Gloucestershire now have a real foothold in this Worcestershire innings.
No doubt whatsoever about this one as he misses Jake Libby's bat and thuds one into his shins.
Both openers gone in quick succession and the game becomes more of an arm wrestle once more.
Durham 50-3 v Northants 450
Ben Stokes edges for a single and up comes the Durham 50 but with a fair bit of damage along the way.
They trail by the small matter of 400 runs.
Essex 184 v Notts 244-5
A mixed first over with the new cherry from Jamie Porter.
His first two balls go for four when erring on leg stump before the fifth one also finds the rope but via a big edge from Lyndon James past the solitary slip.
Dal c Stanley b Anderson 41 (Derbyshire 364 v Lancashire 161)
With only Mohammad Abbas for company, it times to play some shots for Anuj Dal, but he only manages to pick out a fielder in the deep legside off Jimmy Anderson.
A second in quick succession for him but Dal ends with a more than useful 41 and Derbyshire have a lead of 203 runs at halfway.
Lancashire have A LOT of work to do with the bat in 10 minutes or so.
Leics 272-3 v Yorks 185
Dan Moriarty goes too full and Rehan Ahmed clears his leg and launches it for four.
He then gets down and scoops the next for back-to-back boundaries as the partnership moves to 147 and the lead to 87.
Ahmed goes to 125, 11 short of his highest first-class score.
Falconer b Hasan 9 (Kent 416 v Middlesex 47-4)
Hasan Mahmud does it again for Kent!
The Spitfires look like they have struck gold with the skiddy pace of this Bangladesh seamer and he gets one to keep low, skip past Caleb Falconer's defences and flatten off-stump.
Two wickets in four excellent overs for Hasan.
Haydon c Jennings b Stanley 0 (Derbyshire 360-9 v Lancashire 161)
Rory Haydon is not known for his batting and an attempted drive off his first ball goes straight to gully.
But it's a five-fer for Mitch Stanley - 5-80 - and he deserves that for the way he has kept running in hard with his extra pace.
