Somerset 670-7 dec v Worcs 154 & 274-4
We may be just a few minutes away from the close but Brett D'Oliveira still looks fresh and in good nick.
After dispatching Craig Overton's second ball for four, two balls later he unfurls a beautiful cover drive for another boundary to go to 70.
Essex 582-6d v Surrey 365 & 4-0
Jamie Porter's fourth delivery thuds into Rory Burns' pads and the LBW shout might be heard back at The Oval.
It's struck the Surrey skipper outside the line of off-stump - not out.
Warks 454 v Sussex 528 & 94-2

We did say it was going to be an interesting final session today and it's proving to be that.
The scoring has dried up a little bit and I'm not quite sure what that's telling us yet about how the game is might play out, but it's very interesting.
Warks 454 v Sussex 528 & 94-2
We've still got the best part of 11 overs to go at Edgbaston and now there is a pause while James Coles has some attention.
The players take a drink as well.
The Sussex physio has a bobble hat on!
Somerset 670-7 dec v Worcs 154 & 266-4
Kasey Aldridge is hitting the pitch hard and Brett D'Oliveira has to be on his toes to turn a rising delivery around the corner for a single.
It brings up the 150 for the fifth-wicket stand with Adam Hose, off 276 balls.
They came together with Worcestershire in real jeopardy of a quick defeat and are seeing off the new ball nicely.
Essex 582-6d v Surrey 365 & 0-0
Off we go again at Chelmsford.
The Essex attack have already bowled 129.5 overs between them.
We will have a further six overs before the close of day three.
The deficit is 217 runs.
Carlson c sub b Mike 113 (Glamorgan 229 & 232-8 v Leics 427)
Image source, Rex FeaturesOne over to go before the new ball and Kiran Carlson tries to hook a short delivery from Ben Mike.
It takes the top edge and Liam Trevaskis dives forward at fine leg to take an excellent catch and end Carlson's 214-ball innings.
Carlson put on 99 for the eighth wicket with Andy Gorvin, who has now been joined by Shoaib Bashir.
Glamorgan are 34 ahead.
Somerset 670-7 dec v Worcs 154 & 263-4
Brett D'Oliveira plays out six dots to Kasey Aldridge's first over back and then Adam Hose does likewise to Craig Overton.
Five to go at Taunton.
If this pair can hang on to the close, it will be a superb effort. Sorry to jinx it, but would the Pears have hope?
Essex 582-6d v Surrey 365 & 0-0
Essex have enforced the follow-on and Surrey will restart in a few minutes.
Somerset 670-7 dec v Worcs 154 & 263-4

Worcestershire's fifth wicket pair of Brett D’Oliveira and Adam Hose are showing proper application as the Pears try to save the game against Somerset after Tom Banton’s heroics.
There’s still a very long way to go but after being outplayed for most of the match, the visitors are at least demonstrating true grit.
Notts 579 v Durham 378 & 53-2
Ben McKinney has had a tricky start but is perhaps now finding his feet.
He claims his third boundary of the second knock, and then takes a single off Fergus O'Neill to bring up the Durham 50.
It has not come without cost.
Century-maker Lyndon James is thrown the ball for his first over. He'll replace Dillon Pennington from the Stuart Broad End.
Middx 260 & 261-4 v Lancs 359
Lancashire skipper Keaton Jennings wastes no time in calling up Tom Bailey for a burst with the unsullied cherry before stumps.
There are 11 overs left in the day and the Red Rose will be hoping for a positive finish after earlier having Middlesex 7-3 in their second innings.
Somerset 670-7 dec v Worcs 154 & 263-4
An eventful over as Craig Overton attempts to get the new ball talking.
Adam Hose pats the third ball back and Overton picks up and shapes to hurl it straight through the Pears batter. He wisely hangs on to the ball.
The Somerset man then strays down leg and Hose cashes in, flicks it off his pad down to the boundary in front of the Colin Atkinson Pavilion.
Six from the over and the visitors have now more than halved the 516-run first-innings deficit.
Kasey Aldridge will share the new ball.
Roach LBW b Critchley 1 (Essex 582-6d v Surrey 365)
Matt Critchley is back on at the Graham Gooch End and has a huge LBW appeal against Kemar Roach - not out.
Two balls later there's another appeal and the finger goes up.
Surrey all out and Ben Foakes is left stranded 92 not out.
The deficit is 217 runs.
Hampshire beat Yorkshire by five wickets
Jonathan Doidge
BBC Radio Leeds cricket commentator
There's no question about which side that deserved to win, so no problem with that. I'm sure I'll be speaking with Anthony McGrath who will feel like his side have had their chances to really push for something here and they haven't been good enough, both in the field and with the bat on day one.
But I think he'll be very encouraged by some good stuff during this match and they've not been completely overrun by any stretch of the imagination by a team who finished second in Division One last year.
I think there are some wins ahead for Yorkshire but when you're playing at this level, it doesn't matter what the names on the team sheets say, you have to play well and you can't afford to let things slip as they did on the opening day with the bat.
There are definite strong lessons to be learnt and they'll be able to show us whether or not they are putting those into practice when they welcome Worcestershire to Headingley on Friday.
Middx 260 & 261-4 v Lancs 359
Middlesex move past their first-innings score but the new ball will shortly be available to Lancashire.
They need a wicket or two with the home side now 162 ahead and the partnership between Max Holden and Ben Geddes worth 148.
Holden is 126 not out and Geddes has 68.
Haines LBW b Yates 34 (Warks 454 v Sussex 528 & 92-2)
Tom Haines plays all around the spin of Rob Yates and is trapped in front of all three stumps.
The lead is 166 runs.
James Coles is in ahead of the unwell Tom Alsop.
Notts 579 v Durham 378 & 46-2
Colin Ackermann drives down the ground and then twice edges down to third man as Dillon Pennington begins his seventh over by leaking three successive boundaries.
Perhaps time for a change.
Essex 582-6d v Surrey 363-9
Seems a bit harsh but Matt Critchley's reward for breaking that Surrey ninth wicket stand is to be replaced by Simon Harmer.
The South African is on the verge of a 58th first-class 5-fer.
Ben Foeaks hits him for four and enters the nineties.
Somerset 670-7 dec v Worcs 154 & 257-4
Jack Leach whirls away again for his 30th over.
Adam Hose sweeps the second ball to the rope for his 11th boundary and then picks up another couple of runs to go to 76.
A single completes the scoring in the 80th over.
New ball please! Craig Overton will have first use of it, with eight overs left in the day.
