Ravi Bopara gets off the mark with a glorious clip off his toes to the boundary.

Too straight from Kyle Jarvis. The paceman then nips one past Bopara's bat with a beauty.

It's real nip and tuck out there at the moment.

Mike Barnett: It's not hindsight. The fashion to not enforce the follow-on makes no sense. Are the bowlers knackered in April?

Oohs and ahhs everywhere at the moment. It's a super spell from Stephen Parry after lunch and batting is suddenly looking very difficult.

And it's not about to get any easier - Kyle Jarvis is taking the new ball for Lancashire

Finally, the breakthrough for Lancashire after 41 overs today...

Ravi Bopara comes in at five for Essex.

Potentially a new ball to face in an over's time too. Lancashire will want him early.

Tom Westley and Dan Lawrence have now batted for almost 60 overs together.

I'm sure we'll get to see James Anderson soon - they new ball is two overs away.

Four more. 

Dan Lawrence cuts Jordan Clark to the point boundary to move into the 70s.

Poor bowling from the Lancashire all-rounder.

You've got to stop bowling there Jordan!

Jordan Clark bangs in another short one and Dan Lawrence helps it around the corner for his ninth boundary.

Lancashire look short of ideas.

Warwickshire bowling coach Alan Richardson told BBC WM:

"You just can't give sides the sort of start we gave them on the first couple of days.

"We're pleased we showed some fight after that, and Trotty was superb, but this game is a wake-up call for us.

"We bowled well on the second day, too, but overall we're disappointed. We have spoken about how we need to bounce back."

Tom Westley and Dan Lawrence are matching each other blow-for-blow.

Westley punches Liam Livingstone through the off-side to the boundary to move to 59. 

The pitch is offering absolutely nothing at the moment.

More reaction from Surrey skipper Gareth Batty.

"There are some seriously good teams in this division. We have now got the best domestic first-class cricket in the world. The cricket I've seen played in the last two or three years has been the best of my time in the game," he added to BBC London.

"Full credit to Trotty, who is still one of the best players in the country. It was a very good lesson for our bowlers to see how someone that good goes about his business."

Here's a bit of reaction from Surrey captain Gareth Batty after his side wrapped up victory over Warwickshire in less than an hour this morning.

"We're absolutely delighted. Both Mark Footitt and Mark Stoneman will deservedly get the plaudits for their first-innings performances, but we can get better. This is just one win," the 39-year-old told BBC London.

"The fact that we were able to leave out two England players (Jason Roy and Zafar Ansari) is a big statement. But we are not an 11-man team. It is all about the squad. It could be me sitting out the next game because people will need resting and we will always pick the right team for the surface."

The players are back out at Chelmsford.

Jordan Clark will get things under way with the ball - Dan Lawrence to face. Short. Four.

Tim Carlisle: Hameed & Lawrence - both born 1997, played 25 & 26 first-class games, both have four 100s, both average 43.94 #brightfuture

Dan Lawrence has now pushed his first-class average north of 45 with this unbeaten innings, but you're right Tim - both are highly exciting prospects.

Welcome back. Suitably refreshed?

I'm sure Tom Westley and Dan Lawrence will have enjoyed their lunch - their partnership has been magnificent so far.

I'm off to grab a bit to eat.

I'll be back in 30 minutes to take you through what promises to be a fascinating afternoon session at Chelmsford.

What's the betting on a James Anderson masterclass? See you soon.

An impressive display of watchful and disciplined batting from Tom Westley and Dan Lawerence has given Essex real hope of avoiding defeat.

Neither have been tempted into playing at anything wide of off stump and both have been immaculate in defence. 

James Anderson bowled unchanged for the opening hour, but only beat the bat on the odd occasion, and with the pitch looking increasingly flat the home side will be increasingly confident of securing a draw.

Tom Westley and Dan Lawrence get a standing ovation from the Essex crowd as they stroll off for lunch.

The pair added 71 runs in the morning session, but more crucially saw it through unscathed.
