Warwickshire still need 177 runs to make Essex bat again.
Hampshire 419 v Middlesex 150 & 40-1

The reply is underway with Emilio Gay and Ricardo Vasconcelos setting out for a long stint in the middle. They need another 374 to make Kent bat again.
For added context, Daniel Bell-Drummond's first-innings total of 300 would be worth two batting bonus points - as many as Northants and Middlesex have mustered between them all season...
Essex 457 v Warwickshire 158 & 115-3
A beauty from Simon Harmer!
The South Africa spinner pitches on or around leg stump, but gets the ball to spin away from Rob Yates' bat and tickle the edge.
After so much hard work, the Bears opener is undone by a superb piece of spin bowling.
Hampshire 419 v Middlesex 150 & 27-0
Just the 10 scoring shots in the opening 11 overs as Middlesex seek to dig-in at Southampton, though five of them were fours.
Sam Robson has 11 and Mark Stoneman has 16.
The visitors remain 242 behind but Liam Dawson has just been brought on to bowl.
Somerset 163 & 320-5 v Nottinghamshire 186
Bowled him!
George Bartlett's superb knock is over as Dane Paterson crashes one into middle and off-stumps.
However, Bartlett's 265-ball stay at the crease has helped to set the game up for his team as they lead by 297 with five wickers left.
Northants 237 v Kent 621
Since Thursday night Daniel Bell-Drummond averages 480 in professional cricket for Kent.
He made 69 not out at Chelmsford in the Blast, followed it up the next night with 111 against Middlesex at Canterbury and has now amassed 300* in the County Championship.
That's also the biggest score since his old pal Sam Northeast made 410* for Glamorgan at Leicester 11 months ago this week.
Essex 457 v Warwickshire 158 &115-3
New Zealand bowler Doug Bracewell is thrown the ball for Essex and Jacob Bethell greets him with a lovely cover drive.
The bowler then produces an absolute pearler which squares up Bethell and watches as it flies between Sir Alastair Cook and Simon Harmer at first and second slip and races down to the boundary.
Northants 237 v Kent 621
Daniel Bell-Drummond finishes unbeaten on 300 after Arshdeep holes out to Saif Zaib to give Alex Russell his sixth-wicket - 6-175
What a half-an hour that was.
Once all is said and done Kent lead by 384 and have five-plus sessions in which to bowl Northants out.
Northants 237 v Kent 621-9
History for Daniel Bell-Drummond. The third man to make 300 for Kent. The fourth highest individual total for the club. The first opposition player to score a triple at Wantage Road.
He flips Alex Russell down the leg side for a single to reach the .milestone in 530 minutes, from 439 balls with one six and 26 fours.
Yorkshire 550-9 dec v Gloucestershire 232-5
The covers remain on and the clouds are very grey and the scene at Headingley is a depressing one.
With that being the case, lunch is being taken at 12:40 BST with an inspection to take place after that if the rain relents.
Lancashire 274 & 151-5, Surrey 360
Let-off for Lancashire as Phil Salt is dropped on 1 at extra cover by Jamie Smith.
Dan Worrall is the disappointed bowler.
Nightwatchman Will Williams is still there, looking useful.
Northants 237 v Kent 613-9
Leslie Ames is in the rear-view mirror. Daniel Bell-Drummond moves to 296*. The tensest 613-9 you could possibly imagine, this...
Only two Kent players have scored triple-centuries.
Essex 457 v Warwickshire 158 & 105-2
Breakthrough for Essex!
Jamie Porter induces an edge from Warwickshire captain Will Rhodes, but it's put down by William Buttleman.
Will they live to regret that drop? No.
Very next ball, Rhodes is cut in half by Porter and it takes the inside edge and it's safely in Buttleman's hands.
Porter is ecstatic and so are the Essex fielders as that ends a second-wicket stand of 97.
Somerset 163 & 314-4, Nottinghamshire 186
A lovely first hour for Somerset where George Bartlett and James Rew have added 46 to their overnight score.
The floodlights are on at Taunton where it looks a bit grey, so their advantage of 291 runs is starting to feel imposing.
Essex 457 v Warwickshire 158 & 100-1
Almost a slight mix-up between Rob Yates and Will Rhodes but Yates gets in for a single to bring up the century in this innings.
The Bears trail by 199, so LOADS of batting still to do.
Northants 237 v Kent 604-9
Golden duck for Matt Quinn. Jack White pins him infront. Daniel Bell-Drummond is on 293, two shy of Leslie Ames' fourth highest score in club history. Can last man Arshdeep Singh help him get there?
Northants 237 v Kent 603-8
That's a maiden five-wicket haul for Alex Russell who draws Wes Agar forward only to be adjudged to nick to Lewis McManus who takes a smart catch behind the timbers. 5-165 for Russell who has bowled 36 overs.
Matt Quinn joins Daniel Bell-Drummond who is on 292.
Glamorgan 242 & 70-1 v Sussex 203
A fairly serene first hour at Sophia Gardens where Glamorgan have lost opener Andrew Salter to spinner Ari Karvelas for 22.
The hosts lead by 109 with nine wickets in hand.
Lancashire 274 & 145-5, Surrey 360
A stunning overhead catch by Rory Burns - and Surrey at last have a breakthrough at The Oval.
After 45 minutes of Lancashire resisntance - and 32 runs - Daryl Mitchell toe ends a straightish drive back off Dan Worrall and Burns takes two steps back before fully extending himself to execute a great grab.
Nightwatchman Will Williams remains on 18, as Phil Salt arrives at the crease.
Lancashire lead by only 59 runs with half their men gone. Key stage in the game this.
