Keaton Jennings begins again after tea with a three out into the offside off Kyle Abbott.

He is up to 40 as George Balderson plays out the rest of the over, although there is a good touch of shape from Abbott's deliveries.

A Migael Pretorius no-ball is followed by Ben Foakes pulling the next ball to the fence.

Those runs push Surrey into a first-innings advantage.

With 25 overs left tonight, they really could push towards a 100-plus lead by the close of play.

And in the very next over, Ben Compton makes it to his half-century, driving Simon Harmer off the back foot for four.

Compton's 50 comes from 147 balls and the opener has spent almost three hours at the crease - though of course he's crafted a reputation from compiling far lengthier innings than this one!

The three figures are reached for Durham. Only trailing by 598 now...

David Bedingham steers wide to a deep point area and those four runs bring up the 100.

The South Africa batter is on 26.

A welcome milestone for Kent as Ben Compton pulls Matt Critchley for a single to take his partnership with Daniel Bell-Drummond into three figures.

Compton is now three short of his half-century, while Bell-Drummond has 69 to his name and Essex are short of ideas on where a wicket might come from.

A slightly lucky way to get to 50 with a four to the vacant third from somewhat of an edge to Craig Overton.

But Jamie Smith has played lots of lovely strokes on the way to his half-century.

The floodlights are on, there are dark clouds overhead.

It just makes us wonder if we might get through to the end but if we do there are 32 overs remaining

Hampshire have built up pressure really well this afternoon. With Liam Dawson securing down the hotel end of the ground, captain James Vince has rotated his seamers from the pavilion end.

James Fuller's spell up to tea was excellent, he should have had two wickets with Keaton Jennings put down my Nick Gubbins at point. He did find the bottom edge of Josh Bohannon's bat who played onto his stumps, Fuller and before that Kyle Abbott managed to make it feel difficult for the batter, not easy on a very good pitch and with an aging ball.

It’s been a torrid afternoon for Derbyshire’s batters as their innings followed a similar pattern to Glamorgan’s, falling away against the old Kookaburra ball.

Wayne Madsen was the key wicket, making 63 before driving Dan Douthwaite to cover where sub Asa Tribe leapt and clung on at the second attempt.

While one Glamorgan old boy, David Lloyd, enjoyed his return with a punchy 60, Aneurin Donald fell for just seven as he was caught down the leg-side off Douthwaite.

Seamer James Harris has been tight, taking 3-28 in 19 overs, and leg-spinner Mason Crane has been ripping the ball on a helpful pitch, cleaning up the tail with a rank full-toss, a fine googly and a conventional leg-break.

Only a few big blows from Zak Chappell reduced the home lead to 39, which could still be significant.

A very good fightback from after the openers had taken the Lancashire score to 87-0.

Keaton Jennings survives that drop to make tea on 37 and he is the key Red Rose wicket.

As with the first four sessions, probably honours just about even in this one.

Glamorgan have bowled out Derbyshire for 198 in Cardiff - Mason Crane finishing with 4-60. Derbyshire's last seven wickets fell for 68, handing Glamorgan a first-innings lead of 39.

Yorkshire part-timer Adam Lyth picked up a Gloucestershire wicket just before tea, getting James Bracey. Gloucestershire are now 207-6 and trailing by 119 as the evening session gets under way.

Middlesex have started well replying to Northants' 552-6 declared. They're 26-0.

And Sussex are handily placed at Leicestershire on 206-3 at tea - that's a deficit of 132.

That is a big moment.

James Fuller gets Keaon Jennings into a very false shot as the ball bounces on him outside off, but a diving Nick Gubbins can't hold on at point.

That should have been taken.

Nottinghamshire will have to settle for three wickets in that afternoon session, although Calvin Harrison gave Adam Hose a scare with a ball that turned and looped up, perhaps with a mixture of bat and pad, before falling to safety.

The final over of the session was delayed for several minutes while Ben Slater, fielding close in, was checked and given the all-clear after being struck by a full-blooded pull from Worcestershire's Rob Jones, who goes to tea on 38 not out.

Let's hope the light improves when we come back for the final session.

Having declared on a massive 698-3, it wasn't long before Warwickshire were among the wickets.

The Durham skipper Scott Borthwick couldn't get out of the way of a rising delivery from Oliver Hanon-Dalby and was caught behind on 16. That was in the 14th over with Durham on 42.

On a wicket made for runs, it was rather surprising to see Colin Ackermann then get a fourth ball duck moments later, adjudged caught behind off Craig Miles. He seemed surprised to be given out, suggesting he may have hit his bat against his pad.

So, having seen Durham manage just three wickets in four and a bit sessions of play, it was suddenly like buses, with two coming along at once.

But Alex Lees, last season's top scorer in England, has steadied the ship with David Bedingham. Lees has 53 and Bedingham 21. And it still looks like there are many more runs to be had on this flat track. Especially with a 50-yard boundary on the west side of the ground.

A brilliantly dull session from a Kent perspective. Skipper Daniel Bell-Drummond has followed up his unbeaten century on the final day against Somerset on Monday with another 63* here, putting on 90 from 222 balls with the stoic Ben Compton, who is 43 not out.

They have rotated the strike, put away the bad balls and a touch chance for Jordan Cox at slip to oust his old teammate Compton off the bowling of Simon Harmer early in the session was the only real moment to raise the heart-rate.

The 413 run deficit does not matter, the most important digit in today's remaining 32 overs will be the number of wickets to fall.

If they can keep it to one tonight then Kent will have gone a long way to ensuring a share of the spoils at a sun-drenched Chelmsford.

Two overs left until the tea interval and Nottinghamshire would love to prise out another Worcestershire wicket during that time.

Rob Jones is the man they'd particularly like to remove - he's looking well set on 37 as the Pears battle to make inroads on that Notts total of 399.

Hampshire have done an excellent job of reeling Lancashire back in, just as Josh Bohannon and Keaton Jennings were getting going.

George Balderson is in at number four, after scoring two centuries last year at seven.

A word of caution for Red Rose supporters. They were 150-2 v Surrey last week and collapsed in a heap to 202 all out.

That was quite a dramatic dismissal in the end as the leg stump comes flying out of the ground.

Hampshire with two wickets now and from their point of view will be hopefully seeing this as a chance to maybe sneak in a few more?

Potentially in the evening session when it gets a little bit cooler, they'll keep persisting with their lengths then wickets will eventually fall. You just have to be patient.
