Surrey 213 v Worcs 49-4
Surrey are roaring back into this game as Sean Abbott strikes in his first over.
Adam Hose is the fourth Worcestershire wicket to fall, driving on the up from the crease and edging to a crouching Dan Lawrence at slip, who takes it above head height.
Pears captain Brett D'Oliveira is in next.
Somerset 350-4 v Kent
More punishment for Marcus O'Riordan as Tom Banton is forward to drive the spinner over his head for six.
Four more runs driven on the front foot through cover.
The new ball is taken at the other end and James Rew gets a single off Beyers Swanepoel to take Somerset to 350 (and of course a third batting point) in the 80th over.
He's on 95.
Sussex 150 v Yorkshire 73-3
Joe Root has moved up to 25 off 32 balls without blinking.
How often do we see that from the England great?
Leics v Gloucs 316-1
Gloucestershire's first-wicket partnership ends at 316 as Ben Charlesworth is dismissed by Louis Kimber for 126, caught at long-off.
It's a maiden first-class century for the opener.
Lancashire 255-5 v Durham
Sam Drury
BBC Sport cricket writer at Stanley Park
After a six-over spell in the afternoon session, Ben Stokes is back.
The England Test captain is into his 13th over of the day and the good news is that his body seems to be holding up well.
There is none of the grimacing and clutching at his knee that we've seen when he's bowled over the last couple of years.
So far, so good then...
Notts 149-7 v Hants
Dave Bracegirdle
BBC Radio Nottingham commentator
It's been very much a day dominated by the bowlers.
It's been hard going for Notts with the bat, made even harder by the loss of all those wickets early on.
Surrey 213 v Worcs 45-3
An entertaining but all too brief an innings comes to an end.
That's three wickets for Dan Worrall.
Kashif Ali is caught on the crease, edging behind to keeper Ben Foakes, diving in front of first slip.
Adam Hose is in next.

Rob Jones drives Dan Worrall on the front foot through cover for four and Kashif Ali takes successive fours off Jordan Clark at the other end.
One is driven to long off and another is gracefully clipped through mid wicket.
Good counter-attacking spell here from the Pears.
Lancashire 255-5 v Durham
Well, Tom Bruce is still there but George Balderson is trudging off now...
Balderson doesn't really get his footwork right against Matthew Potts and feathers one behind to give the Durham seamer his second wicket.
Matty Hurst is the new man at the crease for Lancashire.
Somerset 331-4 v Kent

The field is brought in for Marcus O'Riordan...
Driven over the bowler's head, down the ground for four runs and that's his first ever red ball century at Taunton!
150 balls. 15 fours and one six.
He holds his arms aloft and takes a moment to soak in the applause.
Lancashire 251-4 v Durham
Martin Emmerson

The last time these two played in Blackpool was in 2007. It was over in two days and 18 wickets fell on day one.
Glen Chapple took seven wickets and Ottis Gibson took eight in an innings for Durham.
Lancashire 251-4 v Durham
Image source, Getty ImagesTom Bruce ensures that Lancashire have at least one bonus point safely stowed away, slashing Matthew Potts to the boundary and then adding three runs later in the over to take his side beyond the 250 mark.
Bruce, who recorded his maiden half-century for the Red Rose in their defeat at Trent Bridge last time out, looks well set to follow that up with another score here. He's 31 at the moment.
Somerset 322-4 v Kent
James Rew is on the back foot and punches Joey Evison to long on to take the fifth wicket partnership to 150 off 210 balls.
Surrey 213 v Worcs 26-2
Frank Watson
BBC Hereford & Worcester
Dan Worrall has hardly bowled a bad ball.
He's been magnificent in this spell.
Somerset 321-4 v Kent
Tom Banton moves seamlessly into the 90s with successive fours driven on the front foot through cover off the bowling of spinner Marcus O'Riordan.
Nine runs off the over in all.
Banton turns a ball from Joey Evison into mid wicket for one to move to 97...
Leics v Gloucs 302-0
This opening stand between Cameron Bancroft and Ben Charlesworth just goes on an on.
Gloucestershire's record first-wicket partnership in first-class cricket is 395.
Sussex 150 v Yorkshire 59-4 - tea, day four

Image source, Adrian Harms - BBC SportTea at Hove and hundreds of people allowed on the outfield, well done Sussex!
This game is back in the balance with George Hill out on the stroke of tea, Joe Root is battling away, but it’s not inconceivable that Sussex might bat again today.
Lancashire 236-4 v Durham
Bright start for Lancashire after tea, with Tom Bruce thumping the first delivery of the session from Callum Parkinson to the fence.
Bruce and George Balderson have taken 11 from the first two overs since the interval as the batting side advance towards their first bonus point of the game.
Surrey 213 v Worcs 26-2
Dan Worrall strikes again.
That ball moved in sharply, beating an attempted straight drive and knocking out off stump.
Jake Libby departs for a torturous 30-ball single and Rob Jones is in next.
Somerset 304-4 v Kent
James Rew drives Joey Evison and the ball is in the air for a while but just evades mid off and runs away for four.
Tom Banton moves back and drives Marcus O'Riordan into mid on for a single to get Somerset to 300 in the 74th over.
Four more runs to Rew, cut square from the crease.
