Nine fixtures in round four of the County Championship
Teams split into three groups of six
Warwickshire, Hants & Lancashire top of groups
Hants bowled out for 92 at Surrey; Clark takes 6-21
Warwickshire skittled for 87 at Durham having been 30-8
Essex opener Alastair Cook scores 68th first-class century
Lancs v Sussex 110-1
Tom Haines has found some good early runs for Sussex.
He passes fifty for a fourth time in 2021 - all of them in the first innings too when it matters most.
This effort is in 68 balls with seven fours.
Smart morning's cricket that for Sussex.
Durham v Warwickshire 21-3
Warwickshire are really struggling at Chester-le-Street.
After Mark Wood removed Rob Yates in his second over, Ben Raine has now dismissed Hanuma Vihari and Bears captain Will Rhodes.
Tough batting conditions.
Glam v Kent 97-4
Michael Hogan has a fourth wicket of the morning for Glamorgan.
Jack Leaning is a little squared up and nicks behind for just 2.
Kent have lost 3-5 in 20 balls and the opening session has been transformed.
One glimmer of hope is that England batsman Zak Crawley is still there on 26.
Derbys v Notts 111-2
Notts opener Ben Slater follows his match-saving century at New Road with a fifty at Derbyshire.
His stand of 80 with Joe Clarke has helped Notts recover from 31-2.
Surrey v Hants 53-7
Hampshire's disastrous morning session has just got worse at The Oval.
Teenage all-rounder Scott Currie, in just his second first-class game, has edged Kemar Roach behind.
Hampshire are 53-7 as Kyle Abbott comes in.
Worcs v Essex 62-0
Image source, Rex FeaturesIt's now almost five sessions without a wicket for Worcestershire's bowlers at New Road.
Nick Browne (22 not out) and Alastair Cook (34 not out) have almost taken Essex to lunch unbroken.
Last time out, Notts openers Haseeb Hameed and Ben Slater batted for four sessions to save the game.
Definitely a decent early-season track for the batsmen at Worcester!
Glam v Kent 88-3
Two in the space of five balls for Glamorgan seamer David Lloyd.
First Jordan Cox feathers a catch behind and then Joe Denly is trapped lbw for a duck.
That has transformed the complexion of the morning in Cardiff.
Somerset v Middlesex 68-1
It's turning into a decent morning for Middlesex at Taunton after the early loss of Sam Robson.
Opener Max Holden and Nick Gubbins are blunting Somerset's excellent attack.
Derbys v Notts 92-2
Ben Slater and Joe Clarke are beginning to build a really useful partnership for Notts at their East Midlands rivals Derbyshire.
Clarke has hit a couple of sixes in his 32, while Slater has 37 as he looks to continue his fine form.
Their stand is worth 61.
Lancs v Sussex 102-1
Excellent start for Sussex and Stiaan van Zyl who goes to a half-century in 81 balls, seven boundaries and a six.
The maximum was planted over long-on off Matt Parkinson's leg spin.
Yorks 67-2 v Northants
It's been a bit gloomy at Headingley all morning and now it's started raining to take the players off.
Surrey v Hants 44-6
Hampshire have been piling on the runs this season.
In their four innings so far they've made 612-5, 319, 290-4 and 470.
Now they're 44-6 at The Oval. Shows anything can happen in this great game.

Incredible.

What is going on?!

Captain James Vince goes third ball as he edges Jordan Clark behind.
It's two wickets in the over for the Surrey all-rounder to put his side in command.
Surrey v Hants 44-3
Hampshire have just lost their third wicket of the morning at The Oval as Sam Northeast edged Jordan Clark to slip for four.
Tom Alsop and Joe Weatherley are also the men back in the pavilion.
Tough start for the Group Two leaders.
Glos v Leics 57-1
Dom Goodman has been a nice little early story of the season.
He's just finished his first year at the University of Exeter but Gloucestershire handed him a debut at Taunton two weeks ago and he did a tidy job with the ball.
That continued last week against Hampshire but it was his batting that made the headlines with a tremendous last-wicket stand with Josh Shaw that survived for over an hour to save the game.
He's now making his home debut and a rare loose delivery has been driven for four by Marcus Harris to raise Leicestershire's fifty.
Yates b Wood 1 (Durham v Warwickshire 6-1)
Mark Wood gets a wicket with just his seventh delivery!
Rob Yates, century scorer and match-winner in Warwickshire's last match, makes just one today as he's bowled by the England paceman.
It's a quick delivery and the 21-year-old was simply too late on it.
Great start for Wood and Durham.
