Warwickshire 473-1 v Durham
Clive Eakin
BBC CWR Sport
A first double century of Alex Davies' career.
He's quite hard on himself, he feels he has underachieved a little bit for Warwickshire in terms of runs scoring in the two years that he's been here so far but what a start to this season.
Notts 303-6 v Worcs
Lyndon James and Calvin Harrison have raised a second batting point for the home side at Trent Bridge in a very good stand now worth 65.
And if they can negotiate these final couple of overs, it will be a pretty good day's work for Notts.
Essex 410-6 v Kent
After Dean Elgar's 120 earlier in the day, Matt Critchley has picked things up for Essex and goes to his eighth first-class century.
168 balls, four fours and a six.
Three overs left by the River Can.
Surrey 28-0 v Somerset 285
A second over for South Africa bowler Migael Pretorius on his Somerset debut.
He drops short and Sibley cracks it through the offside for four.
The Surrey members love that one as Sibley moves to 21.
Surrey 24-0 v Somerset 285
Eight overs into the Surrey reply and England spinner Shoaib Bashir is thrown the ball.
Somerset would love him to pick up a wicket before the close of play.
Glamorgan 237 all out v Derbyshire
Dave Fletcher
BBC Radio Derby Sport
Alex Thomson has seven wickets in the innings.
He's had a real day out here at Sophia Gardens, he gets the congratulations of all of his team mates.
It's been a terrific display from Thompson.
Career-best figures of 7-65 from 26 overs with seven maidens in there.
Hampshire 290-6 v Lancashire
A 50th 50 for Hampshire all-rounder Liam Dawson.
He ticks one into the legside off Jack Blatherwick to reach that landmark. It has taken 117 balls but it is a fourth 50 of this Hampshire innings.
Warwickshire 451-1 v Durham
Martin Emmerson

I never thought I would see the day when a side bagged maximum batting points on day one of a game - for the loss of just one wicket!
Warwickshire reached 450-1 after 89.2 overs, with Alex Davies scoring the first double century of his career.
It came in 249 balls on as one-sided a day as I can remember in 25 years of covering Durham.
Will Rhodes has also reached 50 runs, in a sedate 88 balls.
Warwickshire 454-1 v Durham
It is hard to grab attention when there has been a double ton and a 191 already in the innings, but Will Rhodes has 50.
It's come off a sedate-ish 88 balls, but has allowed the Bears to keep the foot on the pedal.
A second half-century of the season for the ex-captain.
Essex 400-6 v Kent
Simon Harmer has joined Matt Critchley they have brought up a fourth batting point.
And there's plenty of time for the maximum haul too.
Five more overs tonight.
Warwickshire 450-1 v Durham
Lovely shot from Will Rhodes gets him four runs off Brydon Carse. And it's a no-ball.
Those two extra runs take Warwickshire up to 450 and a fifth batting point.
This partnership for the second wicket is now worth 107 runs, too.
Warwickshire 444-1 v Durham
Five days into the season and we have a third double hundred!
Warwickshire captain Alex Davies nudges one off his legs and jogs through to reach the landmark for the first time in his career.
He follows Sam Northeast (335*) and Ryan Higgins (221) to achieve the feat in 2024.
Davies has faced 249 balls, hitting 23 fours and two sixes.
Essex 396-6 v Kent
It was a cracking little innings from Michael Pepper going to the cusp of a half-century in just 41 balls.
But he falls to Nathan Gilchrist with the second new ball.
He tries to glance a back-of-a-length ball outside off down to third man but gets too much club on it and carries it all the way to the fielder.
Kent strike with seven overs to the close.
Surrey 15-0 v Somerset 285
A real sign of intent as Craig Overton bangs one into the pitch and Dom Sibley gets behind it and pulls it away to the mid-wicket boundary.
That is not the type of shot with which most people associate with Sibley!
Overton responds with a cracker that goes past the outside edge and carries through nicely to the gloves.
Hampshire 271-6 v Lancashire
Scott Read
BBC Radio Lancashire
Lancashire have plugged away really well all day.
We've mentioned during the course of the day the challenges bowling with the Kookaburra ball, it's different when it's new like it is now.
But I think under those circumstances and what looks like a pretty good pitch, Lancashire will be pretty pleased with how they've gone about today.
We've had seven batters make centuries today and a couple more closing in. A tough day in the dirt for plenty of fielding sides...
Surrey 7-0 v Somerset 285
Surrey openers Rory Burns and Dom Sibley are at the crease to begin the innings.
Burns gets the first four of the innings when Lewis Gregory drifts onto the pads. That is meat-and-drink to the Surrey skipper.
Hampshire 268-6 v Lancashire
The new ball does the trick for the Red Rose.
Tight stuff from Tom Bailey and Will Williams and Williams has Ben Brown well caught at third slip.
The Hampshire wicketkeeper gets becalmed and falls victim when Williams offers a hint of width.
Warwickshire 413-1 v Durham
Just one ball after Alex Davies plays and misses at one from Matt Potts and he pulls a short one away to the fence for four.
Davies is now on 191, nine away from a maiden double century.
