Hampshire 231 v Nottinghamshire 185 & 142-6
Steven Mullaney gets one through the legside to the fence and moves into double figures.
It is a rare triumph as Kyle Abbott has him next ball!
Abbott gets one in the right place and hits the Notts skipper on the pads.
Mullaney lasted 63 balls whereas it's now 4-27 for Abbott.
Somerset 241-8 v Warwickshire
Jack Davey is out - to end his 105-run stand with skipper Lewis Gregory.
A second wicket in the day for the relentless Oliver Hannon-Dalby as the new ball does the trick for the Bears.
Jack 'The Nut' Leach, scorer of arguably the most famous single in cricket history, is the new man in.
Yorkshire 517, Leicestershire 185-4
Big breakthrough for Yorkshire as Matt Milnes has Colin Ackermann caught and bowled.
Wiaan Mulder is the new man in.
Seven overs left in the day.
Hampshire 231 v Nottinghamshire 185 & 136-5
Kyle Abbott is thrown the ball again for Hampshire.
Notts skipper Steven Mullaney has dropped anchor with eight off 55 balls. Can he keep the South Africa bowler out?
Yorkshire 517, Leicestershire 180-3
Peter Handscomb follows Colin Ackermann to his 50.
Their stand reaches 121. Good combined overseas effort this.
Kent 222 v Northants 117 & 15-1
Image source, Alex Hoad - BBC SportThe shadows are lengthening at Canterbury.
Around 15 overs remaining in the day and Northants are taking their second innings very steadily since opener Ricardo Vasconcelos' departure, inching along to 15-1.
Lancashire 222-8 v Surrey 442
Lancashire number 10 Will Williams is holding Surrey up a bit.
He doesn't have too many shots, but his defence is good and he has kept Colin de Grandhomme company for 40 minutes even if the scoreboard is not moving very quickly.
Somerset 229-7 v Warwickshire
Somerset have finally found two men to stay together and form a decent partnership.
Jack Davey (41) has proved the ideal companion for half-centurion Gregory, who has played a real captain's innings for his 51.
Glamorgan 352-7 v Gloucestershire 165
Glamorgan have just lost their seventh wicket against Gloucestershire with Dan Douthwaite caught by Marcus Harris.
But the hosts already have three batting points in the bag in Cardiff and will be seeking a fourth. They also have a large first-innings lead, having more than doubled their visitors' tally with wickets still in hand.
Kiran Carlson hit 106 earlier and Billy Root is close to joining him in the century club, having compiled 85 so far.
Middlesex 131-5 v Essex 266
Earlier today, everything was going right for Essex. Now, nothing is.
Sam Cook sends in a cracker of a ball that somehow evades all three of Ryan Higgins, wicketkeeper Adam Rossington and the stumps - and runs away for four byes.

Sussex have a second batting point and Nathan McAndrew has struck 31 to go with his earlier five wickets, although they have just lost Jack Carson.
Hampshire 231 v Nottinghamshire 185 & 131-5
What a disappointment for Ben Slater!
He had grafted so hard for his 43 and had just hit Keith Barker for four.
But he attempts a big shot on one knee outside off and is caught at deep cover.
The lead is only 85 and half of Notts' wickets have gone.
Yorkshire 517, Leicestershire 168-3
Colin Ackermann and Peter Handscomb's key fourth-wicket stand has now gone to three figures.
Ackermann is on 61 and Handscomb is just three short of a first 50.
13 overs to go in the day.
Kent 222 v Northants 117 & 6-1
Big early breakthrough for Kent.
It's been an incredibly nervy start from Northants, surviving a couple of hearty lbw appeals and also almost gifting Kent a run-out opportunity.
But their luck runs out as Ricardo Vasconcelos chips one up and Ben Compton takes an excellent if unorthodox catch.
Middlesex 120-5 v Essex 266
This game looked over early in the Middlesex innings when the hosts slumped to 4-4 and 20-5.
But Ryan Higgins (64no) and John Simpson (40no) have dragged them right back into it.
A vital century stand.

Northamptonshire are still afloat in this match thanks to the efforts of Chris Tremain - on his County Championship debut - and Jack White, who shared nine wickets to restrict Kent's lead to 105.
But with 23 overs remaining on the second day, the home side could take big strides towards wrapping up victory if they can dismantle Northamptonshire's top order in the final session.
Tremain must have a liking for Canterbury - in his only other first-class appearance in England, also on this ground, he picked up 4-70 for an Australia XI against England Lions in 2019.
Kent's strong position owed much to Zak Crawley who fought hard in testing conditions to make 91 in nearly five hours at the crease.
Hampshire 231 v Nottinghamshire 185 & 118-4
Kevan James
BBC Radio Solent commentator
The game has got a bit nervy again after that quick three-wicket burst from Kyle Abbott.
Notts started bright and breezy in their second innings as Mo Abbas and Keith Barker weren’t quite their usual miserly selves.
Whilst Abbott took the plaudits for his wickets he was well backed up by James Fuller whose eight- over spell cost just ten runs and he had a very good shout for an LBW decision turned down against Mullaney.

The defending champions Surrey are in total control here.
Lancashire skipper Keaton Jennings added 76 before being bowled by Jordan Clark to spark a dramatic collapse of four wickets for 15 runs.
We should get a full day's play here too. The sun is still shining and players' shadows are starting to lengthen.
The crowd has followed the sun and moved from the left of the pavilion to the right.

Durham are into the Sussex tail after removing Cheteshwar Pujara and George Garton.
Pujara made 115 and Garton 28, but Durham will fancy getting a good first-innings advantage now.
Hampshire 231 v Nottinghamshire 185 & 108-4
Ben Slater and Steven Mullaney are really digging in for the team.
They have added 22 and are trying to take the sting out of the Hampshire attack, as the lead nudges up to 62.
