Yorkshire have been bowled out for 326 at Gloucestershire - a fine recovery from 90-5, led by 140 from Shan Masood.

Earlier Joe Root fell for two, and England team-mate Harry Brook made 26.

Gloucestershire's first innings has just got under way.

Derbyshire spinner Alex Thomson is enjoying an excellent day with the ball against Glamorgan. He has 6-54, with the hosts stumbling to 220-8 in Cardiff.

Northants are in a really strong position against Middlesex on 261-2 - Emilio Gay is 146 not out.

Leicestershire are closing in on 300 against Sussex - they're 291-6 with Liam Trevaskis unbeaten on 67.

Cameron Steel ends with 4-50 with his leg-breaks.

That follows on from his career-best 5-25 v Lancashire last week.

Nine wickets for 75 runs is a super start to the season and gives Surrey yet another option with the ball.

Michel Pepper has come out and gone swiftly up to 27 from 23 balls.

He's swept Jack Leaning for four, lofted him over long-off for six - holding the pose - and then swept Matt Parkinson for four more to raise a third batting point for Essex.

After seeing Nathan Lyon send down 29 overs of off-spin, Lancashire captain Keaton Jennings changes tack by taking the new ball.

400 runs in a day and still 16 overs to go!

Alex Davies reaches the landmark in style, down on one knee Caribbean style as he launches Colin Ackermann for a straight six.

Davies is now on 184.

Worcestershire have the new ball at Trent Bridge and will be hoping it can see off the Notts lower order.

Lyndon James going well on 27 for the hosts with Calvin Harrison on 6.

Nathan Lyon has got through 28 overs today.

He has looked good, there's no doubt about it, this pitch is giving him absolutely nothing but he's probed away, lots of guile, changes of pace, changes of line, trying to put a little more revs on the ball from time to time.

He's always kept the pressure on where he can.

A terrific battling knock from the Somerset captain.

Lewis Gregory hits his third big six off Cameron Steel to move to 49 and then walks through for the single he needs to reach his half century.

He is shepherding this Somerset innings expertly with Shoaib Bashir.

Kent have been quite good in the field today, they've committed themselves well.

Alex Davies has reached his highest total in first-class cricket today. It's been an excellent innings and he's now on 174.

His previous best was 147 for Lancashire against Northants in 2019.

He was rattling along earlier, hitting 20 boundaries in his 150, but has slowed down a bit since then. As things stand there's no reason to think he won't see the day out intact.

A change of bowling, John Simpson has the midas touch and Ben Cox is on his way.

I think he'll be really annoyed with himself, it was a half volley, I'm fairly certain he dragged that on but Tom Clark won't worry about that.

Sussex will be delighted with the new ball not that far away.

An easy single for Alex Davies and that is a 50-run partnership between him and Will Rhodes.

The day cannot end quickly enough for Durham.

This last wicket stand is starting to develop a nuisance factor.

It is worth 31 and last man Shoaib Bashir has contributed a big fat zero.

But Lewis Gregory, who has been dropped by Jamie Smith, is doing a great job of getting runs and farming the strike.

The skipper has 42.

Tom Prest brings up the 250 and his side's first batting point but he is almost on his way back to the dressing room.

He comes down the wicket and lofts Luke Wells over the top. Tom Bruce chases after it from mid-on, and almost gets there but the ball doesn't stick and runs away for four.

Prest moves on to 81.

Notts trying to go again with Lyndon James and Calvin Harrison in the middle.

They've moved their side to a first batting point but Notts need a partnership to take this final session.

Essex continue to make excellent progress at a tick over four-an-over.

Matt Critchley is leading them in this final session, he's onto 67.

But it's Paul Walter at the other end who has brought up a second batting point as he swings Jack Leaning down the ground for six.

It was actually a bit of a leading edge that had the Kent fielders interested for a moment but there was enough club to clear the long-off fence.

Warwickshire continue to tick along nicely at well five runs an over.

But Colin Ackermann produces a maiden over for the visitors. Just a fifth of the innings.
