Gareth Roderick is going along nicely for the Pears.

He's just struck his fourth four and is going at a run-a-ball 28.

The sun has made an appearance again but Lancashire are in a bit of bother.

The deficit is still there, a long, long way to go.

Just the one wicket for Somerset so far this morning as Notts batters Will Young and Joe Clarke approach a 50 partnership.

That wicket was a cracker from Craig Overton to remove Haseeb Hameed but there's not much happening for Lewis Gregory and Shoaib Bashir with the the ball at present.

The hosts still have a big lead of 166.

Yorkshire are certainly not serving up free runs at Lord's.

Middlesex are having to settle for ones and twos at the moment in pursuit of a three-day victory over the White Rose.

Nathan Fernandes is 10 not out and Max Holden has eight.

Interesting shot.

Matty Parkinson floats one up well outside off stump and Dan Lawrence opts to sweep through square leg for four.

That certainly suggests the Surrey batters are in very confident mood.

It's not so long ago that Dom Sibley was opening the batting for England. He has two hundreds already this season but do you see any way back into the Test side for him in the Bazball era?

Spin from both ends now at Canterbury as Matty Parkinson joins Jack leaning in the attack.

Two runs and a couple of singles from leaning's latest over - Dom Sibley is now 121 not out and Dan Lawrence has 67.

Still one-way traffic in this match.

Gloucestershire's Zafar Gohar picks up his third wicket of the Sussex first innings at Hove as James Bracey stumps Fynn Hudson-Prentice for 18. The home side are 314-7, 103 in arrears.

Glamorgan have broken tthrough again at Northampton with James Sales lbw to James Harris, but Karun Nair is still there on 71.

Aneurin Donald and Anuj Dal have posted a 50 partnership for Derbyshire, who are 131-6 against Leicestershire, but still facing the prospect of having to follow-on.

Nick Gubbins is patiently edging closer to his first County Championship century of the season as bat continues to dominate ball at Southampton.

Hampshire batter Gubbins has moved on to 88 off 200 balls having just seen off a maiden from Warwickshire left-arm spinner Danny Briggs.

Hampshire trail by 275 runs.

Worcestershire have been set 458 runs to win which is an unlikely target given that the forecast is not very good for tomorrow and the length of time left in the game would mean that even if the forecast was good they'd have to bat for a very, very long time.

The pitch might turn, it appears to have flattened out, it doesn't appear to have any demons in it.

I think we'll get a good steer on the way things are going to go in the first hour of this innings if they can get through that without too much damage then I think they might start to think that they can save it.

It's going to be a tough ask and Durham have done everything right so far. They won the toss and chose to bat, they got a decent first innings lead and they've capitalised on that. Excellent stuff from them.

Worcestershire's second innings is under way at Chester Road in Kidderminster.

They face a gargantuan task but for now, their focus is just on surviving until lunch with all 10 wickets intact.

Pears opener Gareth Roderick enjoys confidence boosting consecutive fours off Matthew Potts.

They'll need plenty more of that.

Max Holden clips Jordan Thompson away for four - the first boundary of Middlesex's modest run-chase.

There's a lot of pressure on youngster Nathan Fernandes, who has only a single from 11 balls faced, but he then forces Ben Coad away to third man for four.

Graham Clark brought up his 50 right on the stroke of 11.50am and Durham promptly declared, giving themselves an hour to have a go at the Worcestershire batsmen before lunch.

Clark and Ollie Robinson put on 132 for the sixth wicket, with Robinson making 67. He's scored four half centuries in a row so far this season.

There are 83 overs left in the day and Durham are going to have to hope they can bowl Worcestershire out in that time because the weather forecast looks awful tomorrow.

In the last two weeks The Pears have been in good positions to win games going into the final day, only to be thwarted by the elements. Unless they pull off an incredible run-chase here, the elements may be saving them this week.

Dom Sibley dabs a single off Jack Leaning as he and Dan Lawrence post a century stand for Surrey's second wicket.

This is looking ominous for Kent. Where can they find the inspiration to separate these two?

Derbyshire are clinging on against Leicestershire and are now 103-6, replying to the massive 574-7 declared by the visitors.

Glamorgan have taken another wicket at Wantage Road with George Bartlett falling to Brad Wheal for three. Karun Nair is 71 not out and Northants are 349-4 - a lead of 78.

Sussex have a second batting point at Hove - they are 307-6, but still 110 behind Gloucestershire's first innings score.

We're going to see what Worcestershire are going to do.

They're going to have to bat extremely well, it's a tough ask for them today.

Graham Clark reaching his 50 is the signal for Durham to declare on 457.

They have added almost 80 runs in under an hour this morning, with Ollie Robinson shining, finishing unbeaten on 67.

That couldn't have gone much better for the visitors as they now have time before lunch to get into the Pears top order.

The forecast isn't wonderful for tomorrow so that may have been a factor in their early declaration. They want to make sure of victory today.
