Somerset 454 v Notts 193 & 20-1
New Zealand batter Will Young has joined Haseeb Hameed at the crease and he gets off the mark with a juicy half-volley from Josh Davey that is sent to the fence.
Davey is too full again later in the over and Young hits it straight for four more.
Another six overs to go this evening.
Harmer lbw b Wells 9
And Luke Wells duly wraps up the Essex innings.
Similar dismissal to the one that got Shane Snater in his previous over, as he skids one into Simon Harmer's pads.
But Essex go off with a very big halfway lead of 231.
Essex 374-9 v Lancashire 146
Shane Snater goes to whip one from Luke Wells through the legside, but he misses and is hit on the pads.
It may have been a little high, but it's given out.
Worcs 184 v Durham 244 & 266-4

He went for one too many but it's been a fine, fine innings from David Bedingham.
Worcestershire are delighted that they have finally struck but he's done plenty of damage.
He departs for 138 off 98 and the crowd really have been entertained by a magnificent innings.
He just went to carve that one away over the off side, didn't get all of it and it was a terrific catch in the end.
Hampshire 134-1 v Warwickshire 455
Hampshire have started to speed up as we head towards the close of day two.
It's helped by things like getting 12 off an OHD over - a rare occurence indeed.
Fletcha Middleton and Nick Gubbins are both in the sixties and they have taken their partnership to 117.
Worcs 184 v Durham 244 & 265-5
Relief for Worcestershire as David Bedingham slices a catch to Adam Hose, having pulled Nathan Smith for six earlier in the over.
He hit eight sixes and 13 fours in a dazzling 99-ball exhibition which has laid the platform for a Durham push for victory.
They lead by 326 with 15 over remaining.
Middx 246 v Yorks 159 & 124-6
Another one gone at Lord's as Tom Helm bowls Jonny Tattersall.
Just four wickets left for Yorkshire and they are only 37 in front.
Derbys 1-1 v Leics 574-7 dec
That's what an extended spell in the field can do.
Just three balls into Derbyshire's first innings and Harry Came is leg before to Tom Scriven.
Skipper David Lloyd scored the first run but the next 16 overs could be very testing for the home side.
Somerset 454 v Notts 193 & 8-1
There is the first wicket for the hosts!
We said it would be a tricky spell for Notts and Ben Slater is on his way back.
He goes to pull Josh Davey, but the ball gets big on him and it goes high up in the air, but it still needs a terrific catch from Sean Dickson running back from midwicket to complete the dismissal.
Somerset will fancy one or two more wickets before the close.
Kent 244 v Surrey 133-0
Runs coming too easily for Surrey now.
Dom Sibley tucks Matty Parkinson away to mid-wicket and the fielder in the deep can't make up the ground to prevent a boundary.
Must have been very good timing because Sibley just placed that one.
Worcs 184 v Durham 244 & 254-4
Paul Coughlin tries to cut a ball from Adam Finch which doesn't bounce as much as was expecting and an under-edge is safely taken by wicketkeeper Gareth Roderick.
David Bedingham is still there for Durham on 128 and has been joined by the dangerous Ollie Robinson.
They lead by 314.

Richard Clarkson: Took the boys to their (and my!) first @CountyChamp, external match today as @WorcsCCC, external are playing just up the road from us in Kidderminster. A session and a half in the cold was enough for the 7yo but we had a great time! #bbccricket, external
Lovely to hear that, Richard.
Northants have lost Luke Procter for 65, caught off Mason Crane, but they are 221-2 and just 50 behind Glamorgan's first-innings total, with Ricardo Vasconcelos now 122 not out.
Cheteshwar Pujara has reached 50 off 84 balls for Sussex against Gloucestershire at Hove. They are 215-3 and 202 behind with 17 overs to go.
Essex 365-8 v Lancashire 146
Tom Westley loves playing to leg, but comes with a risk, especially to an off-spinner and there is no doubt that he is out to Nathan Lyon as the ball raps him on the pads.
The Essex captain goes 19 short of a ton, but with his side in a wonderful position.
Somerset 454 v Notts 193 & 0-0
Notts have just lost the Somerset tail wag in a big way, but now they have an uncomfortable period to bat.
The sun is out but the home bowlers will be buoyed by their runs as they target Ben Slater and Haseeb Hameed.
Middx 246 v Yorks 159 & 109-5
It's tense stuff at the home of cricket following the dismissal of Joe Root.
George Hill and Jonny Tattersall are batting with care, but there are 21 overs to come and the Yorkshire lead is only 22.
Hampshire 112-1 v Warwickshire 455
After two half-centuries last week against Lancashire, Nick Gubbins has another one against the Bears.
Three fours in a Craig Miles over help him to the landmark, this coming off 104 balls.
But he has loads of batting to do with Hampshire still 343 runs adrift.
Derbys v Leics 574-7 dec
That seems just a little cruel.
With Ben Mike 49 not out off 41 balls, Leicestershire skipper Lewis Hill decided they have enough runs on the board.
It is the club's second-highest total in a Championship game against Derbyshire - they made 619 all out on the same ground in 2017.
Hats off to Marcus Harris, who anchored the innings with a superb 214.
Kent 244 v Surrey 118-0
Dom Sibley is not renowned as a carefree stroke-maker but he responds to reaching 50 by lofting Matty Parkinson down the ground for a maximum.
He repeats the shot to end the over, but this time it falls just inside the rope and it's four.
How are Kent going to separate the Surrey opening pair?
