It's been a typical Dom Sibley innings.

He was very impressive taking on the second new ball last night and just pushing it on but he isn't just going to stop there I don't think today.

A lovely innings, he's having a terrific summer.

Not only did that burst of three quick wickets earn Yorkshire an extra point, it also prevented Essex from picking up one of their own.

Jordan Cox's dismissal was probably the key one in terms of putting Essex off trying to dash for 300 before the cut-off point. Now they're looking to regroup and post a strong total - but it might be a lot lower than looked probably overnight.

Michael Pepper has just leg-glanced Ben Coad for four, but at the moment it's all about trying to keep their remaining wickets intact for the visitors.

Kent skipper Daniel Bell-Drummond is nearing a century against Northants - he is 93 not out in their 392-5. He has so far put on 54 for the sixth wicket with Harry Finch since the dismissal of Joey Evison.

Middlesex are continuing to pile on the runs at Grace Road, where they are 399-6, with Ben Geddes now 66 not out.

Jimmy Anderson's opening spell is over, he's off to have a drink, towel off and cool down in the field.

2-19 from his opening seven overs is a fine return, though he'd have loved to have seen the back of Wayne Madsen before coming off, the Derbyshire skipper is 21* with Brooke Guest content to block at the other end.

Glamorgan v Glos 331-9

James Bracey reaches his third hundred of the season from 170 balls with a push for one off spinner Mason Cranwe, who he hoised for six in his previous over.

When you consider how much of this innings Bracey has been batting with the tail, that is a magnificent effort for his side.

Dom Sibley has reached 200. He was nearly run out getting there as well.

His next target is 245 and a career-best score. His highest total to date is 244 in a draw against Kent in 2019.

Sibley's also added 209 with Dan Lawrence, who has 102.

Surrey's highest fourth wicket stand against Durham is 222, by Darren Bicknell and Ali Brown, in Darlington, in 1994. Expect all records to be broken today.

Chris Rushworth takes the new ball for Bears, with Daniel Hughes on strike and Tom Haines lurking at the other end.

Attacking field set by the visitors... they want early inroads, but the first ball is overpitched and cracked to the boundary by Hughes for four.

A big landmark for Dom Sibley as he pushes George Drissell for a scampered single on the leg side to reach his double hundred - the second time he's done it for Surrey.

Sibley reaches 200 from 356 balls - and next in his sights must be the 244 he posted as a Warwickshire player almost six years ago.

If ever there was a day to beat that, it's probably today against the Kookaburra ball and with the bowlers tiring in the heat.

It's been a lovely innings from Dan Lawrence, he has played some gorgeous shots.

That's the second 100 of the summer for him. He made 100 against Sussex down at Hove. He'll want to go on from here, though.

110 overs are up, no second bowling point for Hampshire.

Jake Libby and Gareth Roderick have added 17 runs in nine-and-a-bit overs to deny them a sixth wicket.

We enter a new phase of the game... how many do the Pears want, and how quickly do they want them?

Jake Libby likes playing on the South Coast. He gets a lot of runs at Sussex and he's got runs here today.

A good innings. He was the foil to Adam Hose yesterday. Hose played more shots but he was there all day, a long day in the heat.

Well batted.

Liam Patterson-White pins Craig Overton on the back foot at the end of his latest over, but it's just missing leg stump.

Three from that one for Tom Banton - who is 81 not out - but both teams will have to settle for two bonus points from this innings.

Surrey 479-3 v Durham

It looked inevitable - and it was. Dan Lawrence registers his second hundred of the season, from 99 balls.

A 19th first-class ton overall for the Surrey batter.

It feels like everything has just clicked in so many ways for Notts (this season).

Of course that's why they are at the top of the table but they've got a really well-rounded side.

They've got a captain who is in the form of his life in Haseeb Hameed and they've got a really strong bowling attack as well led very much by Mohammad Abbas.

Gloucestershire are making Glamorgan wait for this final wicket.

... brought up with a glorious straight six off Liam Dawson, back over his head.

He'd faced 297 previous deliveries, hit 13 of them to the rope, and none of them over it, until now.

Adam Hose will claim the plaudits for this total but Libby has been immense, unruffled and especially good with anything on his legs.

Mohammad Abbas' bouncer can take batsmen by surprise, but not Tom Banton on this occasion.

A meaty pull shot brings him four to backward square and the right-hander moves on to 72.
