Surrey 118-4 v Notts 231
Roland Butcher
Former England batter on BBC Radio Surrey
He's got another wicket and I think he deserves it.
It was a good delivery and Ben Foakes staying on the back foot because of the movement from the previous delivery.
Lyndon James gets the outside edge and a good catch taken.
Warwicks v Essex 74-1
Mike Taylor
BBC WM commentator
Ethan Bamber has had a fine season. He's won a lot of new friends and admirers here among his team mates and Warwickshire supporters.
He's the leading wicket taker for Warwickshire in the Championship this season with 38. He'll need a big finish to get up to 50.
Somerset 43-3 v Hants
Annie Chave
BBC Somerset
The bowlers have been going for the edge and have been getting close so it was only really a matter of time.
Archie Vaughan will be very dissapointed with that, out for 19. An excellent bit of bowling from Kyle Abbott.
Warwicks v Essex 74-1
Michael Booth nips one away from the bat of Tom Westley.
The Essex skipper goes down to prod at the offending part of the pitch.
There is a fair bit out there for the bowlers with both swing and seam.
Derbys v Glamorgan 47-2
Impressive stuff from Derbyshire's new-ball pair, who are now taking a breather. Ben Aitchison took 1-17 from his initial seven-over spell and Luis Reece 1-23 - but they have now been relieved by Zak Chappell and Rory Haydon.
Vaughan c Brown b Abbott 19 (Somerset 43-3 v Hants)
Archie Vaughan is out pushing at an outswinger from Kyle Abbott and Somerset are in a spot of bother three down.
Foakes c Verreynne b James 10 (Surrey 118-4 v Notts 231)
Is this one swinging towards Notts?
Lyndon James serves up another half volley for Ben Foakes to clip to the mid-wicket fence.
James bends his back a bit and goes past the outside edge and then finds the edge to get rid of Foakes.
Three wickets have fallen for 15 runs.
Dan Lawrence strides out.

Bright sunshine here at the moment.
There are a number of grey clouds in the sky which could unfortunately bring a shower but at the moment it's looking really bright and hopefully we'll get a full day's play because yesterday was so frustrating.
Sussex v Yorks 61-0
Sussex hand the ball to Fynn Hudson-Prentice for the first time this morning and he is whipped to the left of mid-on for four runs by Finlay Bean, who is 26 not out, one fewer than partner Adam Lyth.
Durham v Worcs 65-2
Did we say that Matthew Potts was bowling well?
Well he is... but 19-year-old South Africa batter Daniel Lategan has stroked him for four on three consecutive drives to go with the last ball of Potts' previous over.
He has raced to 16 in no time at all and looks a prospect.
Holland b Garrett 18 (Leics 111-2 v Kent)
Image source, Getty ImagesThat is by some distance the best ball bowled by Kent this morning.
George Garrett sends one down which holds its line and clips the top of off stump.
Ian Holland is gone after adding 62 with Rishi Patel, who has now been joined by Lewis Hill.
Surrey 112-3 v Notts 231
Ben Foakes picks up his first boundary of the morning as he whips a Lyndon James' half volley to the mid-wicket fence.
Surrey just looking to steady the ship after the loss of those two quick wickets.
Warwicks v Essex 70-1
Warwickshire have actually bowled quite well this morning with a few play and misses.
But the home side only have that wicket of Paul Walter to show for their efforts.
Surrey 107-3 v Notts 231
Roland Butcher
Former England batter on BBC Radio Surrey
It was a miscalculation by Rory Burns for his wicket. He went too far across his stumps, he planted his front foot right down he middle of the pitch then having to play around it.
He'll be dissapointed because he's battled away so well but Notts will be ever so pleased that they've picked up two wickets in quick succession.
Glamorgan are trying to regroup following the loss of their openers and are 33-2 in the 13th over against Derbyshire, with Sam Northeast and Kiran Carlson now out in the middle together.
Matt Taylor has made a double breakthrough for Gloucestershire, dismissing Luke Procter (21) and Calvin Harrison (4) to leave Northants on 53-2 in the 18th.
James Anderson has won the toss at Old Trafford and put Middlesex in - play will start at mid-day and Arav Shetty will make his first Championship appearance for the Red Rose.
Sussex v Yorks 50-0
Spinner Jack Carson is already into action for Sussex and Finlay Bean whips him away to mid-wicket. They come back for three and that is a 50 partnership with Adam Lyth, which has taken them 18 overs.
Leics 103-1 v Kent
So four boundaries in that Michael Cohen over as Rishi Patel cover drives the final delivery and Leicestershire's total reaches three figures.
