Jordan Cox scores 204 in Essex's 401 all out against Leicestershire
Somerset bowl out D1 leaders Notts for 193 to lead by 117 on first innings
James Coles hits 224 not out for Sussex as they build huge lead against Glamorgan
Jonny Bairstow scores 68 in Yorkshire's 469 all out against Warwickshire
Kent paceman Keith Dudgeon takes 6-21 as they bowl out Lancashire for 87
Kasey Aldridge takes 5-19 as Durham enforce follow-on against Derbyshire
Leaning c Tribe b Hadley 21 (Sussex 143-2 v Glamorgan 155)
Breakthrough.
Little sign of movement for Ryan Hadley, but he finds the edge of Jack Leaning's bat and that's a fairly comfortable catch for Asa Tribe at second slip.
That should lift Glamorgan's spirits for a while.
Notts v Somerset 308-8
Archie Vaughan perhaps sensing that with Notts pushing into the tail, it's now time to get on with it a bit.
Vaughan slaps a back foot drive for four through extra cover off Mohammad Ali.
Thain lbw b Ahmed 2 (Leics v Essex 347-7)
Googly and not picked, or at least, not picked until too late as Noah Thain tries to flick into leg side after it has struck his pad.
A good start for Leics continues and Rehan Ahmed now has 4-85.
Yorkshire 402-6 v Warwickshire
Two more boundaries in an over from Jonny Bairstow takes Yorkshire to a fourth batting point.
There's plenty of time for them to get to maximum batting points for the first time this season.
That will be secondary in Bairstow's mind. His aim is to pile the runs on quickly and put scoreboard pressure on Warwickshire.
Sussex 139-2 v Glamorgan 155
Glamorgan are certainly 'on it' this morning. Just three runs added in three overs so far and Daniel Hughes has yet to add to his overnight 48 not out.
Leach c James b O'Neill 21 (Notts v Somerset 304-8)
Jack Leach cannot add to his overnight score of 21 for Somerset.
Leach smashes a short one from Fergus O'Neill hard and high through mid-wicket.
It's heading for six but for the buckets of Lyndon James on the boundary who stretches out to his right to make a decent grab.
And now O'Neill has four wickets.
Northants 393-7 v Glocs
James Sales clips Matt Taylor through widish midwicket for four and he has his half century in 101 balls, a mini-milestone achieved with nine boundaries.
Middx 300-9 v Worcs
Middlesex number 11 Tom Helm secures the second batting point with a nice drive for four.
300 looks like a decent score on this New Road pitch.
Martin Emmerson

Image source, BBC SportHe might not be in the England squad for the second Test against New Zealand, but that hasn't stopped Ben Stokes preparing for his next game, whenever that may be.
He's at The Riverside this morning and has gone for a net session with Durham batting coach Dale Benkenstein. There's also talk in one national newspaper that Stokes may well play for Durham next week.
That would be against Northants in the County Championship. If it happens, no doubt the media centre will be a lot busier than usual.
Lancs 17-2 v Kent 178
Second over of the day from Matt Milnes for Kent. Second maiden of the day.
Notts v Somerset 304-7
Archie Vaughan is ticking along nicely this morning, moving from 51 to 60*.
His latest couple of runs coming via a lovely cut shot off Mohammad Ali, which is cut off on the boundary but he still picks up two.
Jack Leach will now face his first ball of the day. Fergus O'Neill is running in to try and withdraw the number nine.
Roland-Jones lbw Swanepoel 4 (Middx 296-9 v Worcs)
South African Beyers Swanepoel gets his first wicket with one that nips back and keeps low and traps Toby Roland-Jones.
Worcestershire have their third bowling point. Middlesex need four more runs for their second batting point.
Durham 308-7 v Derbys
Ben Aitchison has his sights set on another five-for this morning, with four wickets already taken on day one.
He is slightly too full, though, and Matthew Potts drives back past the stumps for the day's first boundary.
Yorkshire 392-6 v Warwickshire
Jonny Bairstow reaches 50 for the 110th time in his first class career off the second ball of the day.
The Yorkshire captain turns Ethan Bamber onto the leg side for two to reach the landmark at quicker than a run a ball. He then adds his seventh four off the next ball. (He also has a six).
Yorkshire are getting on with straight away this morning.
Lancs 17-2 v Kent 178
Keith Dudgeon picked up two wickets for Kent in a very tricky nine-over session for Lancashire last night and will hope to carry on where he left off.
There's a big appeal as Dudgeon whistles one past nightwatchman Tom Bailey, who is resuming for Lancashire this morning, but it brushed his whites rather than the bat on the way through to wicketkeeper Chris Benjamin.
And so ends a maiden over to get us started.
Notts v Somerset 300-7
Somerset secure their second batting point.
Archie Vaughan takes a thick edge off Fergus O'Neill and it runs away for four down to third man.
Then Vaughan takes a very quick single to mid-wicket to bring up the 300, getting home safely as Jack Haynes attempted the run out at the non-striker's end but missed the stumps with his throw.
Allison c Kelly b Rehan 2 (Leics v Essex 343-6)
Jordan Cox nudges the first single of the day to amble through for a single and two balls later Rehan Ahmed has a breakthrough to give Leics a bit of hope.
Charlie Allison will be kicking himself here because that was not a particularly good ball, pitched too short and not turning noticeably.
But he has top edged high it to mid-on/midwicket where Nick Kelly takes a simple catch.
Just the start the Foxes were after even if it not quite the batsman they had in mind for the first wicket.
Sussex 136-2 v Glamorgan 155
First order of business for Sussex today - to pass Glamorgan's modest total without losing any wickets. Shouldn't take too long.
Australian Daniel Hughes is 48 not out and partner Jack Leaning has 18. The latter will face Timm van der Gugten first up.
Notts v Somerset 295-7
Fergus O'Neill gets us under way at Trent Bridge to bowl the first over of the day.
Archie Vaughan is on strike.
Time for some cricket.
