Surrey lead by 197 and Cameron Steel is the new batter.
Derbyshire 167 & 53-0 v Leicestershire 574-7 dec
Harry Came has looked the most fluent of Derbyshire openers against the Leicestershire attack so far in Derby and is unbeaten on 33 from 56 balls.
Derbyshire still trail by 354 runs, though.
Kent 244 v Surrey 434-4
Wow.
Jas Singh comes in, Jamie Smith is down the track and swings it away over one of the longest boundaries on the Spitfire Ground.
It's the third maximum of his innings.
Worcs 184 & 140-6 v Durham 244 & 397-5 dec
50 and out for Jake Libby.
He hits Ben Raine for four to reach another fine half-century but he's gone the next ball as the bowler sends down a short, slower ball and Libby doesn't pick it up, spooning the ball up in the air to give Paul Coughlin an easy take.
Libby has one century and two half-centuries in three matches and is batting at an average of 63.
Kent 244 v Surrey 427-4
Where's the ball?
Jamie Smith lofts Matty Parkinson over mid-wicket for six and it takes several moments to locate the ball.
Smith sweeps the next for a single and goes to a 49-ball 50.
The Surrey lead is 184.
Hampshire 267-5 v Warwickshire 455
Pakistan seamer Hasan Ali can scarcely believe he has not got Liam Dawson lbw after he strikes the Hampshire batter on the toe with a full delivery.
He appeals excitedly then, in the manner of Paolo di Canio, puts his hands together and prays to the umpire to change his mind.
Somerset 454 v Notts 193 & 225-2
Image source, Getty ImagesStill only the one breakthrough for Somerset at Taunton today and that seems an awfully long time ago for the hosts now.
Notts were 48-2 when Haseeb Hameed was bowled by Craig Overton early on but Joe Clarke and Will Young have proved immoveable objects since then.
The visitors are 36 behind and any designs Somerset may have had on winning within three days are disappearing quickly.
Northants 551-5 v Glamorgan 271
Karun Nair is certainly looking to get on with it now.
A slog sweep for six off Mason Crane is followed by an audacious lift over the keeper's head for four off Dan Douthwaite.
Three balls later he crashes the pacemen through the covers for another and moves to 170 not out.
Middx 77-3 - target 158
He's been out there for 32 overs for his 35 but Max Holden's vigil is now over.
Jonny Tattersall is standing up to the stumps and he grabs a nick at the second attempt as Ben Coad claims his sixth wicket of the match.
This one could go either way now.
Sussex 428-7 v Gloucestershire 417

BBC Sussex
For the second week in a row John Simpson and Danny Lamb share a 100 partnership as Sussex ease into a lead at Hove.
The run rate has also increased since lunch as Sussex look to establish a lead and hope their spinners can come into play on the final day.
Worcs 184 & 126-5 v Durham 244 & 397-5 dec
Matthew Potts grabs his second wicket, dismissing Jason Holder for four.
A bit like he did in the first innings, Jake Libby is staying put while watching lots of his team-mates depart.
Libby got 61 in the first innings and is approaching another half-century here.
Somerset 454 v Notts 193 & 216-2
Joe Clarke is unbeaten on 106 which is now his highest score of the season.
Only Alex Davies (441) of Warwickshire has more runs than his 374 in the County Championship this season.
Northants 522-5 v Glamorgan 271
Image source, Rex FeaturesA controlled hook from a short ball by Dan Douthwaite brings Karun Nair one to long and and he reaches 150 from 220 faced.
The 32-year-old has a Test triple century to his credit so it's no surprise that he is making the most of a docile pitch.
The Northants lead is now 251.
Middx 74-2 - target 158
Leus du Plooy tries the pull shot which brought about the downfall of Nathan Fernandes, but he gets more bat on it and it sails beyond the rope for six.
The former Derbyshire batter nudges George Hill fine for four in the next over and Middlesex now need 84 more.
Derbyshire 167 & 37-0 v Leicestershire 574-7 dec
Steady going in Derby thus far.
Derbyshire openers Harry Came and Luis Reece both playing fairly watchfully as they bid to avoid an innings defeat to Leicestershire.
Somerset 454 v Notts 193 & 210-2
Anthony Gibson
BBC Radio Somerset
Even though this is a Somerset crowd, they appreciate the skill and batsmanship of Joe Clarke.
A third century in three games from 136 deliveries with 12 fours and a six. A very good innings.
Hampshire 261-5 v Warwickshire 455
Hampshire have lost four wickets for 31 runs as Warwickshire's Hasan Ali picks up his first County Championship wicket of the season.
It's a testing delivery from the Pakistan seamer, just back of a length, which Tom Prest fends to second slip where Rob Yates gobbles up the catch.
This match looked to be drifting towards a draw but has come alive all of a sudden.
Kent 244 v Surrey 398-4
It's hard to be critical when Surrey are looking to push on but Ben Foakes swishes outside off stump without moving his feet and edges George Garrett to the wicketkeeper.
Ryan Patel is next man up for the visitors.
Middx 58-2 - target 158
Nathan Fernandes tries to pull a ball from Jordan Thompson but top edges to George Hill, who is stationed at long leg.
Exactly 100 more needed by Middlesex as Leus du Plooy comes to the crease.
Earlier on, Essex beat Lancashire by an innings and 124 runs.
