Game on...
Hants 308 & 80-1 v Somerset 137
Fletcha Middleton has to go now though.
It's a beauty from Jack Brooks, nipping one back between bat and pad, and rearranging the stumps.
Nick Gubbins is in at three.
Hants 308 & 80-0 v Somerset 137
Fletcha Middleton powerfully hooks Jack Brooks to the backward square-leg fence to bring up his fifth half-century of the season.
It comes from 102 balls, with 10 fours.
Leics 204 v Gloucs 159 & 212
Image source, Rex FeaturesSo Leicestershire need 168 for what would be their third Championship win of the season.
Wiaan Mulder hits Luke Charlesworth on the rear pad and that is his second wicket of the morning, giving the South African figures of 4-61.
The One-Day Cup finalists have a game in hand on the top three in Division Two, so they are still very much in the promotion picture.
Essex 304 v Middlesex 8-2.
Joe Cracknell goes after four balls. Jamie Porter finds the edge and it's another smart low catch at second slip from Simon Harmer.
Two in five balls for Porter in a double-wicket maiden.
Sam Robson has yet to face a ball.
Jack Davies is the new batter.
Essex 304 v Middlesex 8-1
Smart low catch from Tall Paul Walter as Mark Stoneman flashes a slightly loose drive to backward point off Jamie Porter.
The hosts have the breakthrough.
Joe Cracknell is the new man, joining Sam Robson. Cracknell's only previous first-class match was more than two years ago, facing Leicestershire at Northwood in Division Two.
Durham 450-5 v Sussex
What a good acquision Bas de Leede has been by Durham.
A superb straight drive for four off Jaydev Unadkat is followed by an equally good one through the covers.
He is 90 not out as the total moves past 450 and in sight of a maiden first-class hundred.
Yorkshire 297 & 198-2 v Derbyshire 247
Shan Masood and James Wharton have both looked very comfortable in the Scarborough sunshine this morning, as they look to hammer home the Yorkshire advantage.
Masood punches through straight midwicket to bring up his half-century, made from just 53 balls, and raises his bat to warm applause.
His former side will be desperate to see the back of the Pakistan international - they know just how dangerous he can be.
Northants 232 v Lancs 417-8
Just 20 minutes gone but spinner Rob Keogh is thrown the ball for Northants, replacing Ben Sanderson.
George Balderson is on 93 with Tom Bailey on one at the other end.
Will they fall into the trap of playing expansively? Bailey might, he's swept the finger-spinner beautifully away for four runs and followed up with a straight punch to long on for another.
Gloucestershire have lost their ninth wicket at Grace Road, with Dom Goodman bowled by Wiaan Mulder for 15 a couple of overs ago.
The visitors are now 209-9 - 164 in front.
Worcs 284 & 142-9 v Glamorgan 170
James Harris tempts Brett D'Oliveira to have a prod at one outside off, and Sam Northeast takes a good catch down low at second slip.
The Worcestershire captain is furious with himself, swishing his bat in disgust as he drags himself from the middle.
Northants 232 v Lancs 406-8
Good hands from Emilio Gay to take a low catch at slip after a jaffa from Jack White who has 4-86 and 35 wickets for the season.
Tom Bailey is the new man, trying to prevent White collecting a fivefer.
Surrey 396 v Warwickshire 161 & 138
15 minutes and 24 balls is all it takes and Division One leaders Surrey have their eighth victory of the season.
Jordan Clark bowls Chris Rushworth with a full-length delivery for figures of 4-26, but it's Dan Worrall who takes the main bowling plaudits with 5-25 - and 8-59 in the game.
Time for a rest now as Surrey have no game next week before finishing the game against Northants at home and Hampshire away.
They now know that only Essex can deny them back-to-back titles.

Durham 439-5 v Sussex 266
No joy yet for Sussex at the Riverside.
Durham have added 17 to their overnight 422-5 with Graham Clark advancing to 107 and Bas de Leede on 79.
Essex 304 v Middlesex 0-0
Interestingly the visitors have requested the heavy roller to be used before they begin their reply.
Mark Stoneman and Sam Robson head out. Jamie Porter will take the opening over for Essex, who might feel their total was under-par.
We'll see what the pitch does.
Northants 232 v Lancs 406-7
A leg-side clip off the hips from George Balderson off Ben Sanderson is timed supremely and flashes away to the very short boundary rope, just 46 metres away.
The 22-year-old moves into the nineties.
Surrey 396 & 161 & 135-9
Nice shot.
Four slips in position, but Dan Worrall overpitches and Warwickshire number 11 Chris Rushworth clips it effortlessly away for four.
Surrey 396 v Warwicks 161 & 131-9
Almost there.
Dan Worrall finds the edge of Dan Mousley's bat and Ben Foakes takes a simple catch.
The Warwickshire batter departs for 61, made from 77 balls.
Hants 308 & 50-0 v Somerset 137
The play this morning has settled into a similar pattern to yesterday evening, with Hampshire content to plod along, and slowly but surely bat Somerset out of the game.
However, when Jack Brooks strays onto Fletcha Middleton's pads, the Hampshire opener whips him confidently through midwicket for the first boundary of the day.
Middleton moves on to 37, and the lead is now 221.
Essex 304 v Middlesex
Image source, Rex FeaturesEIGHT FOR JOSH DE CAIRES.
8-106 from 39.2 overs. He's holding on to that ball as the sides head off, and rightly so.
Sam Cook can only glance his lofted delivery to Ryan Higgins at slip and the Essex innings is over.
