Here's the state of play in our five matches:

Sussex are closing in on their first championship win of the season against Durham.

They resumed at Chester-le-Street today on 144-3 - just 68 short of victory.

They're now just 38 short on 174-3.

Middlesex have a battle on their hands at Lord's, where they began day four on 68-2, trailing Lancashire by 94.

Sam Robson and nightwatchman James Harris have taken the hosts to 85-2.

Worcestershire remain in control at Grace Road, where Leicestershire are 140-7 a mini recovery after slumping to 31-3.

Harry Dearden and Lewis Hill both fell for ducks to Charlie Morris but Ackermann is still there on 46. The hosts remain 111 behind.

Derbyshire began day four of their match in Bristol on 97-2, a lead of 38 over Gloucestershire and are now 54 in front on 113-3.

A draw looks inevitable in Cardiff where Northants are 539-4 in reply to Glamorgan's 570-8 declared.

Five batsmen have made centuries in the match to date and Rob Keogh is now 83 not out.

This pitch is starting to play one or two tricks with the odd ball keeping low and a nasty lifter bowled by Harry Podmore.

Ambrose gets away with a nick that doesn't carry and runs away through the slips to third man for four.

He gets off strike with a single off the next ball and Milnes defends.

My team are actually starting their season this afternoon with a friendly, but sadly I can't don the whites myself for obvious reasons.

Anyone else out there preparing for their first run-out of the summer? If so, show us how your kit bag is looking after a winter tucked away in the garage.

New batsman Tom Milnes looks on at the non-striker's end as Tim Ambrose blocks out a Darren Stevens over.

The fifth ball drifts to leg and Ambrose pats it away for one.

Milnes leaves the last ball outside off.

Meanwhile, here's a bit of news from Kent CCC...

Sam Hain is also out of the blocks straight away as he drills a full length ball from Harry Podmore straight down the ground for four.

Meanwhile, here's an interesting bit of gossip at Warwickshire HQ:

Rory Burns and Mark Stoneman resume for Surrey in their second innings with a 15-run lead over Essex.

It all looked rather sedate in terms of the pitch for them last night, which suggests chances of a positive result there may hinge on some sort of deal between the skippers.

But, stranger things have happened...

A bit of a freebie first up from Darren Stevens, who greets Tim Ambrose with a full and friendly leg side ball whch the batsman pats away to square leg for four.

Five dots to end the over.

And we're off and running at the Ageas Bowl.

Yorkshire searching for five more wickets to wrap up a big innings win.

Duanne Olivier opening up to his countryman Rilee Rossouw at the start of the day....

Hampshire look like they might be on the receiving end of an innings defeat this week after they handed one out to Essex last week.

Yorkshire need just five more of their second innings wickets as the hosts are still 198 runs adrift of making them bat again.

But first-team manager Adrian Birrell knows his team must fight all the way...

This could be a very tense morning at HQ for Warwickshire.

The pitch has played well so far but Kent have piled on the pressure with a glut of runs on the board and good disciplined bowling.

Sam Hain and Tim Ambrose are at the crease.

Lancashire will fancy their chances of being able to force a win on the final day at Lord's against Middlesex.

A century on day three from Rob Jones (122) helped them register a first-innings lead of 162.

Late wickets from the bowlers as well helped that victory bid and Jones caught up with BBC Radio Lancashire at the close on Saturday...

I awoke to steel grey skies across the North East this morning and thought this could be a good day for the bowlers.

Although the track has flattened out a bit here in Chester-le-Street, Sussex can't use the heavy roller again. With cold conditions and the cloud cover this could well be a morning for the seamers.

If Durham can take a couple of early wickets, then it will be real test of the mental character of Sussex too. However, if Stiaan Van Zyl and Laurie Evans are able to settle down early and continue their partnership, the visitors will wrap this one up before lunch.

But I cast my mind back to August 2016. Durham, with five wickets in hand, returned on the third morning at Taunton needing 46 to win and lost! These things do happen.

Sussex are just 68 runs short of wrapping up a hard-fought win against Durham.

It's been a game of real grind for batsmen at Chester-le-Street but Stiaan van Zyl will resume on 66 not out for the visitors.

Earlier, David Wiese took 5-43 to set up the run chase and he spoke to BBC Sussex at the end of day three.

Bright, but not that warm has pretty much been the theme weather-wise throughout this round of fixtures.

And it looks set to continue that way for the last day according to our colleagues at the BBC Weather centre.

Chance of a shower further west later in the day I'm told....
