Word is that Keith Barker was warned for running down the wicket.

Rory Burns probably wished he hadn't after falling just two balls later.

Ollie Pope has a little nibble at the final ball of the over and almost gets an edge as it flies through to wicketkeeper Ben Brown.

Dom Sibley then takes a single from Felix Organ before Pope gets on the front foot and pushes through the covers for his first boundary. Classy shot.

He moves to eight.

Essex have had to work so hard for wickets today so this is a big let-off.

Harry Finch takes on the short ball from Aaron Beard and hits it straight down to deep square leg, but Matt Critchley shells it.

How costly will that prove to be?

Yorkshire are clearly targeting Rob Keogh.

James Wharton doesn't get to the pitch of that one but makes a clean enough contact to clear the long-off boundary.

There's a mix-up with Shan Masood later in the over as Wharton sets off for a second and has to get his skates on to avoid being run out after his partner says 'no, thanks.'

Spinner Felix Organ returns to the Hampshire attack in place of Kyle Abbott.

His fifth ball prompts a shout from the close-in fielders as a pad-bat from Ollie Pope almost reaches the man at short midwicket.

Pope then squeezes the final ball into the offside for a couple.

Leus du Plooy seems to be seeing it well early in his innings.

He flicks Ollie Robinson for four through mid-wicket and then chops Jack Carson to the backward point boundary in the next over.

He is 17 not out.

Keith Barker strays on to Dom Sibley's pads and the former England opener turns it fine round the corner to the fine leg boundary.

He moves to 14 off 58 balls.

A few batters to come before this is a consideration, but there are question marks over whether Ben Foakes will bat.

The England wicketkeeper injured his back while batting on day one. He's been off the field since his innings came to an end.

I think the key to this match could well be Dom Sibley. He has the potential to be the glue that holds this Surrey innings together.

If Hampshire can get Sibley early doors then I think they'll be cock-a-hoop.

Australian batter Marnus Labuschagne turns his arm over in tandem with Mason Crane.

Three singles and a leg bye is the result as Leicestershire close to within 69 runs of Glamorgan's first knock.

Matty Hurst tucks Rob Yates away into the legside for a single and that is Lancashire's first task achieved.

They avoid the follow-on at least, although they remain 149 runs behind with just three wickets remaining.

There's the second fifty of the match for Yorkshire's skipper.

He turns Ben Sanderson for two to reach his half-century off 72 balls.

But let-off follows as third slip Ricardo Vasconcelos dives across in front of Emilio Gay at second and neither can hang onto the catch.

In case you were wondering, pace bowler Jack White is not on the field for Northants. He's had injury problems since pre-season so we hope it's nothing serious.

Spinner Rob Keogh pulls one down short and Shan Masood has loads of time to pull it over mid-wicket for six.

Leus du Plooy is not what you might call a 'plodder' and provides an early show of intent as he sweeps Jack Carson for four. Partner Sam Robson is now 82 not out.

Unlucky.

Shan Masood gets away with a big inside edge which just misses the stumps and then hits the helmet behind keeper Lewis McManus.

You can probably imagine what bowler Siddarth Kaul makes of that.

Mason Crane is straight on after lunch in tandem with James Harris and keeps things tight with two maidens.

Scott Currie breaks the spinner's run of 14 dots by taking a couple and then scampers through for a rushed single to move to 25.

There will be a 15:00 BST inspection at Bristol, where the players have been off the field since rain arrived about 15 minutes before the scheduled lunch interval.

Graeme van Buuren and James Bracey both have unbeaten centuries.

New batter Tom Bailey gets off the mark from his first ball.

He has some immediate work to do as the Red Rose still need to pass the follow-on target of 135.

Rory Burns drives Keith Barker for four through the covers for a boundary and the first runs of the afternoon after back-to-back maidens.

Kyle Abbott is already causing problems here.

His eighth ball of the innings just clears the top of off-stump after Dom Sibley belatedly decides to leave.

Then the next brings a drop as Sibley plays forward and edges low to second slip.

Difficult chance but it's grassed. Another maiden from Abbott.
