It's a double change by Yorkshire and it's time for spin, courtesy of Dom Bess. Nothing particularly threatening there, but it's a maiden to Will Rhodes.

First change of the morning by Yorkshire and here comes Matthew Revis.

It's a decent start but Will Rhodes helps himself to a single and is 23 not out - partner Sam Hain has 35.

Here's the Jamie Porter wicket which sealed Essex's innings victory over Lancashire earlier this morning.

The result sees Essex move up to fourth, and Lancashire drop a place to third having been overtaken by Hampshire who were mightily impressive against Somerset yesterday.

Great take by Harry Duke who is standing up to the stumps but manages to cling onto a Steven Patterson bouncer.

Probably not the sort of delivery you want to have to deal with when you're a keeper.

Following that soporific start, Northants have roused themselves with a couple of quick boundaries.

A poor ball from spinner George Linde was flicked away fine by Gareth Berg and Lewis McManus ran Matt Quinn down to third man at the start of the next over.

A steady opening half-an-hour for Notts.

Haseeb Hameed has just sent an Alex Thomson delivery to the ropes to move on to 17, while his batting partner Ben Slater is on 16.

They require another 129 for victory and Derbyshire need to get a wicket soon if they are to have any chance of stopping them.

No joy yet for Yorkshire, but it's another tidy over by Steven Patterson, which costs him only a single. Warwickshire now 125 behind.

From Loser92: "#bbccricket, external - Essex are having a strange season. They’ve just beaten third placed Lancs by an innings but they got hammered themselves by Warwickshire in April (by 10 wickets)."

We don't think they'll be too far from the top come the end of the season.

Sam Hain clips Jordan Thompson away through square leg for four and raises a 50 partnership with Will Rhodes. It has taken them 190 balls following yesterday's exercise in self-denial.

Hain is 30 not out and Rhodes is on 19.

We could be in for a long day at Wantage Road.

Five overs bowled this morning, not a single run scored by Northants.

Ben Stokes will have the pads on in the Durham dressing room, we assume. For now, though, it is still Scott Borthwick and nightwatchman Matt Salisbury out there in the middle.

Borthwick ends Tim Murtagh's latest over by square cutting for four and he has made a positive start to the day.

Ben Slater (9*) and Haseeb Hameed (5*) are finding their feet, adding 12 to the overnight total so far.

They require another 142 runs to seal a win over Derbyshire in what has been a hard-fought contest.

A boundary at Headingley as Jordan Thompson strays onto Will Rhodes' pads and the left-hander flicks it away.

He is now 15 not out and Sam Hain has 20.

Jimmy Anderson - nineteen years on from his England Test debut (see 10:37 BST post) - feels his way in before hitting Simon Harmer to the boundary on the fourth delivery of the over.

Lots of boundaries to get us started at Old Trafford.

Avoiding the follow-on is the first order of business for Northants.

Darren Stevens opens up with a maiden to Lewis McManus, who remains on 29 not out.

Matt Quinn has the ball at the other end and there's nothing doing from his first over of the day either.

As you were - Northants are 172 in arrears.

Luke Wood and James Anderson have an unenviable task ahead of them this morning as they face Essex opening bowler Sam Cook.

But Wood has gone straight on the offensive - 10 from the first over!

Not the length to bowl.

Toby Roland-Jones' second delivery is short and Scott Borthwick has all the time in the world to swivel and pull it away for four.

Just 32 runs added by Sam Hain and Will Rhodes in the final 27 overs of play on day three. How will the two Warwickshire batters approach it this morning?

Jordan Thompson opens up for Yorkshire and there is a single for Hain to get the Headingley scoreboard moving - 147 more needed to clear the deficit.
