Surrey 173 v Notts 231 & 198-8)
Mark Church
BBC Radio London commentator
I think Liam Patterson-White was trying to guide that down to third man and it's a sharp catch from Ollie Pope and Patterson-White's fantastic innings comes to an end on 58.
Patterson-White c Pope b Worrall 58 (Surrey 173 v Notts 231 & 198-8)
As is often the case, one wicket brings two.
Liam Patterson-White's excellent innings is over as he snicks a Dan Worrall delivery to Ollie Pope who takes a smart catch in the slips.
Josh Tongue is in.
Notts lead by 256 runs.
Leics 459-7 dec v Kent 2-0
Harry Finch flashes at a ball from Chris Wright and is fortunate to see it fly wide of the slips. An excellent stop on the third man boundary by Shan Masood keeps him to one.
Geddes c Jennings b Bailey 52 (Lancs v Middx 171-7)
Big flash at a wide short one from Tom Bailey and it flies high to Keaton Jennings at second slip.
Surrey 173 v Notts 231 & 196-7

Another five wicket haul for Matt Fisher. He's now got 10 in the match. What a time to get the wicket and what a game he's having.
Lyndon James is caught by the keeper for 47. If you look at the context, this partnership could be a match-winning one for Nottinghamshire.
Durham v Worcs 309-5
Dave Bradley
BBC Hereford & Worcester cricket commentator
It's been a very good 84 from the Worcestershire skipper.
So 170 is Worcestershire's highest fifth-wicket partnership against Durham.
Somerset 359-7 v Hants
That is a shocker.
Kasey Aldridge has gone for the sweep off Washington Sundar and it has popped up off his glove behind wicketkeeper Ben Brown for an easy grab.
Toby Albert and Fletcha Middleton, fielding at slip and leg slip, have both gone for it and then both left it and it falls safely.
Dear oh dear.
Surrey 173 v Notts 231 & 196-7
Brett Hutton pulls Matt Fisher to the fence.
Fisher repeats the short delivery two balls later and Hutton repeats the shot.
That brings up the 250 lead for Notts.
Hands up how many had them getting that far ahead when they were 89-6?
Thought not...
Coles c Revis b Hill 29 (Sussex 84-4 v Yorks 194)
Jonny Bairstow is standing up to the stumps for George Hill.
James Coles can't believe what he has just done as he chips a catch to Matthew Revis stationed at mid-wicket.
Yorkshire are bowling themselves right back into this game at Hove.
Leics 459-7 dec v Kent 0-0
No Ben Compton in the Kent side for this one - so it's another Ben, Dawkins, and Harry Finch to face the music at Grace Road.
Chris Wright has the new ball and he needs three wickets to reach 600 in first-class cricket before retiring at the end of the season.
Warwicks v Essex 306-5
Don Topley
BBC Essex
Essex have got 13 to score 50, that would be the ambition but tomorrow morning we're going to see another six before that bonus point is finished.
I doesn't matter if Essex give bowling points to Warwickshire, we're just worried about what we can achieve because to get batting points will help Essex's cause with those four other teams in relegation trouble.
Derbys v Glamorgan 250-9
Andy Gorvin edges a ball from Ben Aitchison past second slip for a couple and Glamorgan earn a batting point.
There is no further addition, though, before James Harris edges Luis Reece and keeper Brooke Guest dives to his right to take the catch and end his innings on 31.
D'Oliveira b Conners 84 (Durham v Worcs 309-5)
Brett D'Oliveira tries to jam down his bat on this late but it is through and already hitting his stumps.
Luke Procter has bowled Miles Hammond for one and Gloucestershire are 46-3 in the 21st over, having dismissed Northants for 206.
Glamorgan are just two runs away from a batting points against Derbyshire - they are 248-8, a good recovery after being reduced to 99-6 earlier on.
James c Foakes b Fisher 47 (Surrey 173 v Notts 231 & 180-7)
A 10-wicket match for Matt Fisher.
Surrey needed that.
Fisher gets Lyndon James edging to Ben Foakes.
Notts lead by 238 runs - a brilliant effort from James.
Brett Hutton is the new man to the wicket.
Warwicks v Essex 300-5
A second batting bonus point for Essex.
Michael Pepper has played well for his 42 so far.
It's been a tough day for the Warwickshire bowlers.
Somerset 350-7 v Hants
Kasey Aldridge skips down the wicket to take Washington Sundar on the full and clip a single towards mid on and Somerset have a third point in the match.
Cox c Stewart b Evison 93 (Leics 459-7 v Kent)
Ben Cox lofts Joey Evison down the ground, Grant Stewart takes a good catch and there is the declaration.
Cox hit 16 fours in his 85-ball innings and his team will have about 18 overs this evening to try and make inroads into the Kent top order.
Corey Flintoff ends his first bowling spell in Championship cricket with 0-91 from 15 overs, but he showed plenty of guts and effort against a confident home side.
Somerset 352-7 v Hants
Annie Chave
BBC Somerset
An excellent ball by Kyle Abbott, the bowling was just very impressive and a bit too tough for Ben Green to be facing the new ball.
Durham v Worcs 301-4
Brett D'Oliveira hits Shafiq Ghafari for three and the Pears have a second point in the match.
