Notts 81-4 v Somerset 310
This has been a profitable 40 minutes with the ball since lunch for Somerset.
The visitors have taken two wickets for 31 runs.
Durham 377 v Derbys 26-3
What's that saying about an old dog and new tricks?
Wayne Madsen is unwilling to let Ben Raine just plonk them down on a length and uses his feet to come down the pitch before whipping it away to the mid-wicket boundary for his second four.
Worcestershire 60-2 v Yorkshire 469
Brett D'Oliveira starts to get in the act now. Shortly after being nearly run out he hits his first boundary,
The third wicket pair then bring up the 50 partnership for which they've had to work hard.
Leics 20-2 v Essex 401
Image source, ShutterstockSheridon Gumbs (right) is making his first class debut
It is proving slow going for Sheridon Gumbs on debut but, to be fair to the former Surrey academy player, he will not face a tighter opening attack than Essex.
Gumbs has 6 from 33 deliveries which is not exactly flying but he is still there and does look quite assured at the crease.
The 22-year-old left hander, full name Sheridon Sohan Emmanuel Gumbs, scored 79 not out in a T20 for the Leics 2nd XI against Notts 2nd XI last time out but this is a very different test and pace.
Price c Cooke b van der Gugten 4 (Sussex 289-6 v Glamorgan 155
They delayed it for two overs but Glamorgan have now taken the new ball, which is in the hands of Timm van der Gugten.
Tom Price is squared up by one which keeps a little low, but manages to jab the bat down on it in time.
He's gone to the next, though, feathering a catch to keeper Chris Cooke.
Clarke b Gregory 36 (Notts 81-4 v Somerset 310)
Image source, ShutterstockThat could be a big wicket for Somerset.
It's well wide of off stump from Lewis Gregory but Joe Clarke can only succeed in chopping it on as he tries to cut it away.
Clarke scored 92 for Notts against Somerset at Taunton but struggled early on here and goes for 36.
Lancs 87 v Kent 178 & 31-1
A carbon copy from a couple of overs ago as George Balderson sends one down wide of off stump and Sam Northeast obliges by swatting it away for four through backward point again.
Four more to the total for Kent, who now lead Lancashire by 122.
Mousley b Ali 2 (Warwickshire 38-2 v Yorkshire 469)
Dan Mousley plays on, off an inside edge against Hassan Ali prompting a typically flamboyant celebration from the Pakistan bowler.
A blow for Warwickshire who had been trying to dig in after lunch.
Ali then greets Sam Hain with a glorious delivery which beats the bat.
Worcs 50-2 v Middx 339
Gareth Roderick is beginning to reap the rewards of his earlier watchfulness.
One boundary has been followed by two more as Worcestershire fight back.
Lancs 87 v Kent 178 & 25-1
Big shout for lbw from the Lancashire field as George Balderson strikes Sam Northeast's front pad but that looked to be hitting well outside the line of off stump.
And then Northeast rocks back to cut away for four through backward point to keep the scoreboard ticking for Kent.
Bit much asking Rehan (Ahmed) to bowl 23 overs and then sending him out at three. Are we to take it that he won't be balancing the England side in Stokes's absence?

Montgomery b Raine 5 (Durham 377 v Derbys 16-3)
Ben Raine angles one in at Matthew Montgomery, who inexplicably offers no shot and his off stump is knocked out of the ground.
The pressure really on Derbyshire now as captain Wayne Madsen walks to the crease.
Worcs 39-1 v Middx 339
The locals applaud enthusiastically as Worcestershire finally score a boundary in the 19th over of their innings.
Gareth Roderick cover drives Sebastian Morgan for four.
Simpson b ul Hassan 34 (Sussex 274-5 v Glamorgan 155)
Image source, Adrian Harms/BBC SussexBonus wicket for Glamorgan with the old ball as John Simpson plays down the wrong line to Zain ul Hassan and loses his off stump.
Boosted by that dismissal, Glamorgan delay taking the new ball as spinner Mason Crane continues.
Crane sends down a full toss which James Coles hammers over long-on for six.
Ahmed lbw b Snater 5 (Leics 11-2 v Essex 401)
Shane Snater gets his man and the Foxes are looking a little hunted.
England all-rounder Rehan Ahmed is a touch unlucky as that grubs its way through on the low side, but there is little doubt it was in line.
Essex may have been a touch disappointed with their batting this morning but the bowlers are at the party.
Warwickshire 29-1 v Yorkshire 469
Attritional from Warwickshire since lunch with just two runs added in the first five overs of the session.
Yorkshire were also cautious at the start of their innings before going on to score at an impressive rate.
Former Yorkshire player Jordan Thompson, who's now with Warwickshire but not playing in this game, has suggested while guesting in the commentary box that the home side may have been too attacking arguing that they missed a chance to make 550 plus.
McCann c Rew b Leach 33 (Notts 69-3 v Somerset 310)
Image source, ShutterstockThe spin of Jack Leach has done the trick for Somerset.
Freddie McCann is given out caught behind by wicketkeeper James Rew and proceeds to storm off very quickly.
McCann doesn't appear to think he feathered that but the Somerset field and umpire certainly think he did.
Either way, Notts are now three down, still trailing by 241 runs. In comes Jack Haynes for the hosts.
Reece b Potts 9 (Durham 377 v Derbys 16-2)
Luis Reece - what have you done.
He moves across his stumps to try and flick Matthew Potts away to backward square and is bowled behind his legs.
Caleb Jewell will replace him in the middle.
Phillips c Vasconcelos b Proctor 9 (Northants 465 v Glocs 20-1)
And the skipper has the breakthrough.
Luke Proctor had a big (and surely very close) shout for an lbw turned down a couple of balls before but there is no doubt about this.
Shaping away from the bat late, Joe Phillips has tried to play it down into the off side but edged it behind.
Ricardo Vasconcelos, deputising with the gloves, dives low to his right in front of first slip to take the catch – and a very good grab it is too.
First blood of the afternoon to the hosts.
Sussex 268-4 v Glamorgan 155
Mason Crane and Zain ul Hassan continue for Glamorgan, who are looking to the second new ball in four overs' time.
John Simpson square drives ul Hassan for four as the Sussex lead increases to 113.
