Durham 150-3 v Sussex 361
They have lost three wickets since lunch but Ollie Robinson and Colin Ackermann bring up the 150 for the home side.
Essex 296 v Hants 176-4
I would imagine Hampshire head off for the tea break fairly happy with where they are in the game.
Tilak Varma has batted well for his 56 with Liam Dawson on six.
The visitors trail Essex by 112 runs and will fancy a decent first-innings lead.
Warwickshire 37-1 v Somerset 498
Craig Overton eventually gives himself a bowl from the City End after 12 overs.
Three slips and a gully in place, he knows Somerset have to attack early to take wickets to win this match, even if they leak boundaries.
Parkinson c Bailey b Wells 11 (Lancashire v Kent 352-9)
The end is nigh for the Kent innings.
Lancashire are the only team of the 18 in action yet to bat but they won't have to wait long.
Matt Parkinson skies one and it's an easy catch for Tom Bailey.
Durham 133-3 v Sussex 361
Ollie Robinson chips one back in the air but it's just out of the reach of Fynn Hudson-Prentice on his follow through.
Robinson has hit two sumptuous boundaries but his heart would have skipped a beat there.
He and Colin Ackermann like to score quickly so Sussex need to part these two.
Essex 296 v Hants 176-4
Tilak Varma has batted within himself for the most part today, but he unfurls a magnificent reverse sweep to Matt Critchley's leg-spin which flies away for six.
Patel c Cooke b ul Hasan 70 (Leicestershire 201-2 v Glamorgan 353 AO)
Rishi Patel hit four off the first ball of Zain ul Hasan's tenth over to get past 200, but fourth ball the Glamorgan all-rounder earns an inside edge caught behind.
Lewis Hill joins Rehan Ahmed.
Yates c Rew b Pretorius 17 (Warwickshire 33-1 v Somerset 498)
First wicket for Somerset.
Strangled down the legside the first legal delivery (no ball first up) from Miggy Pretorius who had just come on as the first change from the Pavilion End after Josh Davey's 4-2-7-0.
Tom Latham at three, I said on record yesterday he could get 300 v the kookaburra ball on this pitch when he also knows the main opposition strike bowler pretty well too...
We shall see, I am sure Matt Henry will fancy at least one more over to have a go at his team-mate anyway!
Worcs 214 v Surrey 225-6
Surrey move into the lead after the earlier carnage of the afternoon.
Could those five penalty runs come back to haunt them though?
Dan Lawrence moves ominously onto 30 from 52 deliveries with four fours.
Notts 487 v Yorkshire 33-1
James Wharton defends a straight delivery back to bowler Dillon Pennington, who tamely throws the ball back in the batter's direction.
It's nowhere hitting Wharton and it wasn't malicious, but the umpires decide it merits five penalty runs.
Wharton defends the next ball and Pennington points out to the umpires that he's stood outside of his crease.
Rhodes c Hughes b Hudson-Prentice 24 (Durham 115-3 v Sussex 361)
That's a really soft dismissal.
Fynn Hudson-Prentice angles one in on middle and leg and Will Rhodes just chips it straight to Daniel Hughes at mid wicket.
Sussex needed that and Hudson-Prentice has 2-6 in his eighth over.
Budinger c Northeast b ul Hassan 118 (Leicestershire 180-1 v Glamorgan 353 AO
Zain ul Hasan takes the first wicket for Glamorgan.
He is hit for four by Sol Budinger first ball, then sliced into the air to cover-point second ball.
102 balls for his 118, his maiden first-class hundred he will not forget.
Rehan Ahmed in at three.
Essex 296 v Hants 163-3
Kevan James
BBC Radio Solent commentator
Tilak Varma looks a very good player indeed.
Unfazed by accurate bowling, he gives as much attention to his defensive shots as he does his attacking ones.
He reminds me of Sai Sudharsan (currently playing at Headingley) when he first appeared for Surrey two seasons ago.
So correct in technique.
The 22-year-old is available to Hampshire for four championship matches. With their batting not pulling up any trees yet this summer, Varma is a major addition.
Brown c Elgar b Critchley 42 (Essex 296 v Hants 164-4)
Hampshire looked completely at ease with Tilak Varma and Ben Brown in the middle, but Brown has to go after chopping a shortish delivery from Matt Critchley to point.
Essex 296 v Hants 163-3
It should have been a wicket, but instead it's 50 for Hampshire's Tilak Varma.
He defends into the off side and sets off for a single that isn't there. The shy at the stumps misses though and Ben Brown survives.
A flurry of wickets falling in two Division Two games.
Derbyshire have slipped from 301-2 to 309-5 as centurions Wayne Madsen (123) and Harry Came (103) both fell in quick succession at Gloucestershire.
Their lead is already more than 120 though.
Northants are down to 138-4 after Middlesex's earlier 413, with Luke Procter (62) becoming Zafar Gohar's third victim of the afternoon.
Leicestershire 164-0 v Glamorgan 353 AO
Sol Budinger reached 95 by pulling Timm van der Gugten for six.
He then gets to the landmark in similar style smashing Mason Crane over long for six too.
His third six, plus 14 fours.
His maiden first-class century and in quick time, just 92 balls.
Dramatically he is nearly bowled/stumped/caught behind the following delivery to a Crane googly!
Worcs 214 v Surrey 202-6
The 200 is up for Surrey as Jordan Clark drives the ball away for four.
The noise levels have gone up at New Road.
Just going back to the Mitchell Santner decision, on replay it looks a rough one but not only did he point to his bat at the umpire but also slammed it into the turf as he made his way off.
It's certainly livened things up and Worcestershire are right in this game having looked all but gone at lunch.
Durham 104-2 v Sussex 361
Jofra Archer's second spell is six overs where he took 1-8 and bowled three maidens as well.
He's got that lovely, relaxed approach to the crease and certainly troubled the batsmen with the reward of the wicket of Emilio Gay.
Worcs 214 v Surrey 198-6
You may have noticed the Worcestershire score has been changed to 214.
They have been awarded five penalty runs because of Mitchell Santner's reaction to being given out.,
Basically it's a five-run penalty for dissent so they now have 214 rather than 209.
It's all happening at New Road.
