Clark b Patterson-White 121 (Durham 633-8 v Notts 407)
Graham Clark goes off to a warm ovation after his three-hour stay comes to an end.
He looks to rock back and cut Liam Patterson-White but chops on. Super knock from the Cumbrian.
Declaration time? Not a bit of it.
Ben Raine joins George Drissell. The lead is 226.

Warwicks 175-7 - target 310
Ethan Bamber lines up James Fuller and pulls a short ball for six over the forward square leg boundary.
Heart may have been in mouth for a second as it just evades Brad Wheal's leap on the rope. 135 needed.

Somerset 36-3 - target 150
Hard to believe we've only had seven-and-a-half overs of Somerset's run chase and it's already 36-3.

Caught by Simpson really well - he went leaping across to claim the catch.

Rew c Simpson b McAndrew 6 (Somerset 30-3 - target 150)
Image source, Getty ImagesWhat is happening?!
Sussex are really making Somerset work for this and they've got another big wicket!
James Rew has been one of their standout performers with the bat this season but he's gone for just six, wafting at one well outside off stump from Nathan McAndrew and nicking through to wicketkeeper John Simpson.

Warwicks 167-7 - target 310
James Fuller to get what is likely to be final session of the match under way.
Che Simmons to face.
Fuller took three wickets for three runs in 12 balls in a marvellous spell this afternoon.
His 11th over costs just the single from Simmons.

Somerset 30-2 - target 150
Every single run will be very valuable indeed for Somerset and skipper Lewis Gregory won't care that this boundary was via a thick edge off Nathan McAndrew.
It flies down to the rope at third man and Gregory then plays a square cut into the off side for another single.
Now Somerset need 120 more runs to beat Sussex.

Surrey 512 v Yorkshire 255 & 69-2 - trail by 188 runs
Play has resumed at The Oval following the tea break and Yorkshire will continue their quest of trying to bat, bat and bat a bit more to take this game as far into day four as they can.

Durham 602-7 lead Notts by 195
Martin Emmerson
BBC Radio NewcastleThat's centuries in back-to-back innings for Durham's Graham Clark.
Two weeks ago he made his highest score, 160, in a draw at Hampshire.
Today he got to three figures with a risky single on 99. It took 144 balls, 9x4s and 1x6.
It's the third time Durham have had at least three centurions in an innings v Notts.
The total has just reached 602-7 which is the ninth time they have reached the 600 mark in FC cricket.
Their highest score is 648-5d , which was against Notts, here, in an innings win in 2009. The week they retained their county title.

Somerset 22-2 - target 150
Some light relief for Somerset as James Rew forces three off Ollie Robinson before Lewis Gregory grabs another single and then the hosts pick up a leg bye.
Robinson has figures of 2-10 from his first two-and-a-bit overs.

Durham 611-7 v Notts 407
Graham Clark takes Lyndon James for two boundaries in three balls to move Durham past 600.
Notts continue with the old ball.
George Drissell decides to free his arms and wallops Liam Patterson-White back over his head for a big six. And that takes the lead beyond 200.
And on they bat.
WICKETpublished at 16:17 BST 18 May
Budinger b Paterson 25 (Leics 30-1 - target 102)
Middlesex at least have a wicket here.
It's full outside off stump from Dane Paterson and Sol Budinger, who has been trying to get a shift on, drags on.
Still another 72 runs needed to win for Leicestershire. The hosts need a few more quick wickets to cause a scare.

Somerset 13-2 - target 150
Ollie Robinson with another beauty to James Rew first ball but he manages to get it away. What a first three overs we've had in this second innings.
Exciting stuff now.

BBC Radio SomersetSomerset are in trouble.
An lbw without scoring - still 139 short of their target.
This is certainly not going to be straightforward.

Lammonby lbw b Robinson 0 (Somerset 11-2 - target 150)
Wow!
It's another beautiful looping in-swinger from Ollie Robinson and this time he has got Tom Lammonby lbw!
Sussex have got their tails up. Somerset might have thought 150 was going to be a fairly easy target to knock off. They might have to think again.
We do have a game on indeed.
100 for Graham Clarkpublished at 16:12 BST 18 May
Durham 593-7 v Notts 407
Image source, Getty ImagesI wonder how Graham Clark enjoyed his interval cuppa while stuck on 99 not out.
George Drissell takes a single off Liam Patterson-White to bring Clark on strike.
And there it is! He pushes his first ball after tea down the ground and scampers a quick single to bring up back-to-back centuries.
His sixth first-class ton has come off a brisk 144 balls with nine fours and a six.
Well batted.

Worcs 358 & 134 v Essex 157 & 89-6 - Essex require 247
A good session for the hosts and Matthew Waite in particular who took 3-10 from six overs.
Noah Thain is providing a little resistance for the visitors, he's on 23, with Simon Harmer on six.
The Pears remember are looking for their first win of the season.
