Hants draw with Glos; Derbyshire draw at Durham
Warwickshire 102-1 (target 256) v Essex
Image source, Rex FeaturesIt's all looking rather comfortable for Warwickshire's batsmen under sunny skies at Edgbaston.
Hanuma Vihari and Rob Yates' stand is now worth 91 with both approaching their half-centuries.
Essex need a spark from somewhere.
Warwickshire require another 154 runs for victory.
Hampshire 470 v Gloucestershire 320 & 106-4
Tom Lace and Ian Cockbain's 50 partnership had taken Gloucestershire over the 100-run mark in their second innings.
But Lace departs shortly after they reach the milestone, caught by Joe Weatherley off Brad Wheal's bowling.
He made 38 from 102 balls and Ryan Higgins now joins the action.
Stevens c Jones b Parkinson 0 (Kent 169 & 311-7 (f/o) v Lancashire 525)
Darren Stevens lasts only five balls before finding Rob Jones at cover off Matt Parkinson and Kent are in danger of collapsing.
They've lost three wickets in the last four overs, while scoring only six runs.
They still trail by 45 in the follow-on.
Warwickshire 77-1 (target 256) v Essex
Essex spinner Simon Harmer has rattled through nine overs, conceding just 11 runs.
But crucially for Warwickshire, no breakthroughs for the South African.
The Bears need another 179 in a minimum of 53 overs for victory.
Denly b Lamb 31 (Kent 169 & 311-6 v Lancashire 525)
After removing Heino Kuhn in his last over, Danny Lamb is back to take out Joe Denly in his next.
Denly made 31 from 92 balls, including three fours.
It's all looking a bit precarious for Kent now, who still need 45 to just draw level.
Image source, Rex FeaturesWorcs 436 v Notts 276 & 173-0 (f/o)
Notts opener Haseeb Hameed (78 not out) has now spent exactly 700 minutes batting in this match at New Road.
401 minutes in the first innings, and 299 in this.
Another 20 minutes in the middle and it'll be 12 hours. Epic.
Durham v Derbyshire 130-3 (target 384)
Matt Critchley and Wayne Madsen are looking good for Derbyshire after they lost Leus du Plooy shortly after lunch.
Critchley (20 not out) has just gone to 400 runs for the season at an average of exactly 80.
Kent 169 & 310-5 (f/o) v Lancashire 525
Image source, Rex FeaturesHeino Kuhn has gone.
The South African has fallen for 32, adjudged lbw to the bowling of Danny Lamb.
Joe Denly is joined in the middle by Ollie Robinson who wastes no time in hitting Lamb for four with his first ball.
A small measure of revenge.
Northants 364 & 87-2 (target 355) v Glamorgan 407 & 311-5
Two wickets in two overs for Glamorgan has changed the complexion of this one!
Ben Curran went lbw to Callum Taylor for 24, then Charlie Thurston lasted just three balls before being dismissed by James Weighell.
Northants had been motoring on very nicely but their momentum has just been checked.
Warwickshire 68-1 (target 256) v Essex
Image source, Rex FeaturesBoom! Where did that come from?
Warwickshire opener Rob Yates has been happy to nudge the singles so far, but he decides to take the attack to Essex spinner Simon Harmer and launches him over long-on for six.
Warwickshire need another 188 for victory.
Worcs 436 v Notts 276 & 162-0 (f/o)
Openers Haseeb Hameed and Ben Slater have gone a long way to saving the match for their side now as they take Notts into the lead.
Batting is looking very easy at the moment as both batsmen close in on tons.
Kent 169 & 292-4 (f/o) v Lancashire 525
Heino Kuhn and Joe Denly have reached the 50 partnership for Kent at Canterbury.
The duo have dug-in since Daniel Bell-Drummond, Zak Crawley and Jack Leaning were dismissed in quick succession during the morning session.

Northants 364 & 77-0 (target 355) v Glamorgan 407 & 311-5
Northants are in hot pursuit of Glamorgan's total and Ricardo Vasconcelos has made a run-a-ball half-century to help them along.
He did it in style too, with consecutive shots to the boundary.
They need 278 more for the victory.
Durham v Derbyshire 97-3 (target 384)
Durham have just picked up a third wicket at Chester-le-Street.
Ben Raine pinned Leus du Plooy lbw for 29.
Seven wickets to go.

Warwickshire 48-1 (target 256) v Essex
Image source, Rex FeaturesHanuma Vihari and Rob Yates resume batting for Warwickshire.
208 more needed, nine wickets in hand, two sessions remaining. Wonderfully poised.
How big a role will Essex's talisman Simon Harmer have to play this afternoon. Can he find some turn?
Our six remaining games are getting started after lunch. Big sessions coming up in all of them...
Lunch: Warwickshire 48-1 (target 256) v Essex

Warwickshire go to lunch on 48-1 needing 256 to win with a minimum further 67 overs available.
Essex's last wicket occupied a further 12 overs this morning before Jamie Porter was lbw to Briggs for 11 leaving Simon Harmer 82 not out.
Skipper Will Rhodes was caught behind off Sam Cook for 11 but Hanuma Vihari and Rob Yates saw Warwickshire reach 48-1 at the interval.
Lunch: Durham 475 & 175-2 dec v Derbyshire 267 & 87-2 (target 384)

I predicted this morning this would be a long hard day of cricket. And so far it has proved to be so.
Derbyshire used the heavy roller before play began. Durham found to their cost at Trent Bridge two weeks ago how difficult it can be to get all 10 wickets on the final day when the heavy roller has been used. Notts only lost five on that occasion and so far today Derbyshire have lost only two.
Luis Reece was in obstinate mood and eventually faced 110 balls before he was given out lbw to Scott Borthwick in the 32nd over. It was a breakthrough Durham needed and came about 20 minutes before lunch. He made 32.
Prior to that the only other wicket to fall was Tom Wood, who was unexpectedly bowled by Ben Raine in the 19th over. He lost his middle stump on 25 during a period of play in which nothing seemed to be troubling the batsmen.
There are 64 overs left and I still believe we will be here well after tea. Durham certainly have their work cut out if they are to take the remaining eight wickets. They will need to be patient and hope it pays off.
Lunch: Hampshire 47- v Gloucs 320 & 67-3 (f/o)

Hampshire started the day needing all 10 Gloucestershire second innings wickets, and in the process, hoping they wouldn't get too far ahead if at all.
The first 50 minutes were quiet, then 'bang, bang'
First of all Chris Dent went to a fine juggling catch at slip by Liam Dawson, then in the next over Kraigg Brathwaite holed out to mid-on off Dawson.
If you think I haven't mentioned the left arm spinner enough in this short piece, well, he had James Bracey caught at slip driving out of the rough.
Wickets are still hard to come by if batsmen are only focused on defense. But depending on who you suppor t- Gloucs are nowhere near safe yet, Hampshire may still run out of time.
