Warks 27-0 - target 388
Warwickshire safely see out eight overs to tea through Rob Yates and Alex Davies.
There should now be another hour of gentle batting to do after the break until a draw can be declared.
Essex 582-6d v Surrey 365 & 164-3
Image source, Rex FeaturesSurrey go through the session without losing a wicket and without really looking like losing one.
Since edging the first ball of the day just out of the reach of slip Dom Dibley has done what Dom Sibley does which is occupy the crease and accumulate quietly.
Essex failed to remove Ben Foakes in the first innings and are having the same issue again.
It was always going to be a tall order to take 20 wickets on this surface and that's how it's proving.
Notts 579 v Durham 378 & 289
Martin Emmerson
BBC Radio Newcastle
It looked like this game may have been edging towards a draw by mid-afternoon, thanks to a gutsy partnership from Colin Ackermann and Graham Clark.
They put on 145 for the sixth wicket and appeared to have piloted their side to calmer waters, only for everything to go a bit Josh Tongue! (We have to thank a listener for that one).
Clark was on 62 when he was bowled at the start of the 80th over, and Tongue then through the rest of the Durham order. He took four wickets for four runs in two overs, including Ackermann for 124.
Durham lost 5-21 in six and a half overs and were all out to leave themselves with a lead of just 88 runs. Tongue finished with 5-66.
I said Durham needed to bat until well after tea to save this one. But they didn't.
Notts need 89 to beat Durham
At 268-5 and Colin Ackermann going very well with Graham Clark Durham were moving into safer territory.
But they were always vulnerable having conceded such a hefty first-innings lead.
And so it proved as Notts ripped out 5-21 in just 38 balls. Josh Tongue claiming 5-66.
The hosts should now mop up this small target to claim an opening round win.
Lancs 107-3 - target 309
Marcus Harris off-drives Zafar Gohar for four to get off the mark.
The Australian is using his feet to try and negate Gohar's spin and nudges the final one of the over to mid-on for a single.
Lancashire need 207 off 41 overs to win.
Somerset 670-7d v Worcs 154 & 407-7 - trail by 109 runs
Ooh, Matthew Waite edges Archie Vaughan just wide of Lewis Gregory at slip and away for four runs.
We've got eight minutes until tea which would be another landmark for the visitors.
Hands-up who had this one going to the final session of the fourth day after Tom Banton's antics?
Put your hand down, I don't believe you!
Lancs 102-3 - target 309

As swinging yorkers go, that was an absolute belter.
Jones b Roland-Jones 44 (Lancs 102-3 - target 309)
That is as good an inswinger as you will see anywhere.
TRJ produces a brilliant delivery which dips in late and finds the substantial gap left between bat and pad by Michael Jones.
Suddenly the Lancashire run-chase is unravelling and Middlesex may now be fancying their chances.
Matty Hurst comes out to join Marcus Harris - three wickets have gone down for nine runs.
Potts c & b O'Neill 1 (Notts 579 v Durham 378 & 289)
Fergus O'Neill with the final wicket and Notts have created mayhem in the last half hour.
Matty Potts pushed forward too keenly and nudges sharp chance back to the bowler's chest and he clings on well.
It leaves Notts just 89 to win after tea.
Somerset 670-7d v Worcs 154 & 401-7 - trail by 115 runs
How many times might a side get 400 in their second go and face losing by an innings?
It's a rhetorical question folks, please do not respond as you may still be charged.
Essex 582-6d v Surrey 365 & 159-3
Meanwhile, back at Chelmsford Noah Thain is the latest man to be handed the ball in a game of bowling pass-the-parcel.
Ben Foakes nudges a single followed by Dom Sibley unfurling a straight drive for four runs.
It's not happening for Essex.
Lancs 102-2 - target 309
Zafar Gohar turns one enough to find the edge of Michael Jones' bat.
Blake Cullen dives full length to prevent the boundary, but Jones adds three to move to 44 not out.

The run rate will naturally now slow down (after those two wickets).
D'Oliveira lbw b Vaughan 121 Somerset 670-7d v Worcs 154 & 398-7 - trail by 118 runs
Finally!
Brett D'Oliveira's long vigil is over and he may count himself unfortunate.
The Worcestershire skipper leans a long way forward to Archie Vaughan, is struck on the pad and up goes the finger.
The ball had a long way to travel but he's out after facing 340 balls in 407 minutes.
Ben Allison is in - will this one end quickly now or do the visitors still have more resistance in them?
Somerset 670-7d v Worcs 154 & 398-6 - trail by 118 runs
Image source, Rex FeaturesThat's an eighth 50 in first-class cricket for Matthew Waite.
It's come up off 195 balls in a stubborn rearguard action with his captain Brett D'Oliveira with six fours.
Will it be a match-saver?

Jones and Jennings were cruising along but things have changed. That was an excellent over in what is a really good spell of bowling (by Zafar Gohar).
Bohannon b Gohar 0 (Lancs 98-2 - target 309)
Big error of judgement by Josh Bohannon.
He stays back to a good-length arm ball from left-arm spinner Zafar Gohar, which scuttles on off the pitch and cleans him up.
Australian Marcus Harris - a centurion in the first innings - is the new Lancashire batsman.
Somerset 670-7d v Worcs 154 & 395-6 - trail by 121 runs
We have now had 150 overs in this Worcestershire second innings.
That's more than we had when Somerset were piling-up 670 in their first dig.
The visiting skipper Brett D'Oliveira has been out there for the best part of seven hours.
Ackermann lbw b Tongue 124 (Notts Notts 579 v Durham 378 & 279-9)
And another for Notts!
Josh Tongue gets his fifth to bookend the over with wickets.
This time it's Colin Ackermann, who's resistance finally comes to an end.
Full and straight again and Ackermann is beaten for pace, his drive is too late and is plumb lbw.
What a return for Tongue!
Surely nothing stopping Notts now.
Essex 582-6d v Surrey 365 & 150-3
It's a milestone for Surrey but the only number which really matters is that of 37.3 overs remaining in the day.
A handshake at 5:00pm is beginning to look more and more likely.
