Alex Davies finds the ropes for the first time in an age as opens the face to glance George Balderson's wide delivery past the slips and down to the fence at third.

Might only squeeze more more over in before tea so a late finish in store... weather and light permitting, of course...

I would have thought that Somerset would set the their sights on five Durham wickets before close of play today.

They'd like more obviously but five would be a very good start.

Just two singles from the final three overs before tea at Wantage Road which arrives with Yorkshire having added 114 during the afternoon.

Northants will be very glad indeed to have seen off Adam Lyth for 109 but Shan Masood is well set on 46 not out and the home side will be very well aware of his propensity for big scores.

New partner James Wharton has a single to his name. Remember, no Joe Root or Harry Brook in this match.

A fine session for Sussex which brought 120 runs for the loss of just one wicket - James Coles who fell to a terrific catch from wicketkeeper Jack Davies.

Cheteshwar Pujara is still at the crease having moved to a patient unbeaten 60 off 142 balls while John Simpson reaches tea on 22.

Just 38 more runs required for the first batting point.

The visitors are clearly intent on trying to get through to tea with nine wickets in hand.

Five overs to negotiate, three of those likely to come from Nathan Lyon who is probing away like the wily old fox he is.

Alex Davies has 30 from 69 deliveries, Will Rhodes is on 13 from 58 balls.

No rush, whatsoever.

A change for Somerset with Jake Ball coming into their side to replace Migael Pretorius, who was struck on the helmet during his innings of 53 and will play no further part in the game.

It will be Craig Overton to lead their attack, though, and Alex Lees pushes the ball past mid-on and picks up three runs and get the scoreboard moving.

Dan Lawrence, all arms and legs, takes the final over before tea as Surrey look to spin to make the breakthrough.

A single apiece for Toby Albert and Fletcha Middleton. Lawrence builds a bit of pressure but Albert plays out for dots.

It's been astunning session for Hampshire and Kyle Abbott.

Surrey resumed at 99-4 after lunch, but were skittled for 127 as the South African completed a superb five-wicket haul.

Toby Albert (4) and Fletcha Middleton (18) then survived an awkward hour to reach tea unscathed 99 runs behind.

Can Hants press home their advantage after tea?

Four runs from the final over of the afternoon by Graeme van Buuren and that's been a highly satisfactory session for Derbyshire.

They have added exactly 150 and Matt Lamb and Brooke Gues are still together, their fourth-wicket stand now worth 207.

Lamb has hit 19 fours and is 109 not out and Guest is only six runs away from his first century of the season.

Alex Davies and Will Rhodes have knuckled down, just a leg bye and a single off the past four overs.

The run rate has dropped anchor, halving to just over two-and-a-half an over.

There were some eyebrows raised then they opted to bat first on a murky day with the opening session having been washed-out, but they have enjoyed the best of it, so far...

England skipper Ben Stokes has followed up his five-for at Blackpool on Sunday with a four-wicket haul today, as Durham made lightish work of the Somerset line-up.

Migael Pretorius was the man who held them up with 53 runs before he was eventually out, caught at second slip off Stokes by Colin Ackermann.

In an innings in which Somerset struggled from the off, he offered the only major resistance, putting on partnerships of 35 for both the seventh and eighth wickets with Tom Banton, who made 36, and Josh Davey, who made 10.

The ball has been seaming around but we also have a bit of sunshine now, so maybe batting will be a bit easier. One thing is for sure though. It was a good toss for Durham to win.

We are now at tea and 43 overs remain in the day.

Arafat Bhuiyan is trying his best to rope-a-dope Tom Westley, nagging away outside off-stump and going up and down in pace, trying to tempt him into chasing one which will see the back of him.

Joey Evison has really impressed this afternoon, even if he only has one wicket to show for it.

It's been Essex's day so far, but if Kent can make inroads in the 32 overs which remain then it will represent an impressive comeback, with lead bowler Wes Agar still off the field with a shoulder injury.

A big effort from Matt Lamb, this will mean a lot to him.

This is his first century as a Derbyshire player.

A terrific innings.

A great moment for Matthew Lamb as he puts away a low full toss from Ed Middleton and punches the air as he reaches three figures off 143 balls.

It's a been a fine innings, featuring 18 fours, and he has put on 193 so far with Brooke Guest.

Well batted, Adam Lyth, who completes his third century of the season, and 35th in first-class cricket, with a cover drive for four off Luke Procter.

It has taken him 193 balls and he has hit 10 fours in total. What a way to mark your 200th County Championship match.

Sussex are laying the foundations for a good first innings total here at Lord’s.

Henry Brookes almost prises out John Simpson who edges behind, but wicketkeeper Jack Davies cannot hold a tough, low chance.

Cheteshwar Pujara then glances a legside delivery from Ryan Higgins to the boundary as the visitors bring up 200 in the 58th over.

Not a million miles away from the gloves of Davies.
