Yusuf run out 7 (Durham 664 v Notts 407)
Codi Yusuf hits Freddie McCann straight to midwicket and sets off for a run.
His partner George Drissell disagrees and sends him back. Joe Clarke completes a routine run out.
Durham take a 257-run lead on first innings.
Warwicks 189-7 - target 310
This is a super effort from Warwickshire's eighth-wicket pair as they chip away at the chase.
Things looked pretty hopeless when Che Simmons joined Ethan Bamber with the score on 157-7.
But they have batted sensibly and have got through 15 overs unscathed, adding 32 runs and bringing the deficit down to 121.
Simmons has 13 from 49 balls and Bamber is within 16 runs of his fifty.
Ahmed c Davies b Sharma 20 (Leics 79-3 - target 102)
Another consolation wicket for Middlesex as Rehan Ahmed goes.
He's caught behind by wicketkeeper Jack Davies off 19-year-old Naavya Sharma who picks up a second wicket of the match on debut.
Surrey 512 v Yorkshire 255 & 100-3 - trail by 157 runs
Jonny Bairstow is his usual attacking self. He's on 11 from just seven balls and trying to help Yorkshire get the scoreboard ticking.
James Wharton moves onto 43 with a single to bring up the 100 for the visitors.
Durham 651-9 v Notts 407
Dave Bracegirdle
BBC Radio Nottingham commentator
Good catch by Rob Lord, it was skied up into the air.
It's Patterson's sixth five-wicket haul, his best figures were 5-41.
He's through 50 overs, he toiled through today.
Worcs 358 & 134 v Essex 157
Frank Watson

Image source, Rex FeaturesGareth Roderick equals the Worcestershire record (held jointly by Steve Rhodes and Ben Cox) for most dismissals in a match picking up his ninth catch in this game (five in the first innings)
Can he claim the record by picking up one of the last two wickets?
Leics 69-2 - target 102
Middlesex youngster Naavya Sharma goes for six runs off his third over and Leicestershire move onto 69-2 and now need just another 33 runs for victory.
Raine c Lord b Patterson-White 10 (Durham 651-9 v Notts 407)
Image source, Getty ImagesLiam Pattterson-White's toil and persistence gets its rewards as he completes the sixth five-wicket haul of his career.
Ben Raine top edges the spinner down to Rob Lord in the deep who takes a steepler.
Codi Yusuf comes to the middle.
Surrey 512 v Yorkshire 255 & 83-3
Mark Church
BBC Radio London commentator
The interesting thing here is that Clark is not overly attacking.
It was enticing for Tattersall, a very good catch from Sibley.
Bairstow will not just allow Surrey to bowl at him, it will be interesting to see how he does this.
Jennings c Andersson b Tickner 35 (Lancs 458 & 62-1 v Derbys 314)
Blair Tickner makes the breakthrough.
Keaton Jennings' 43-ball knock comes to an end as he lifts Tickner down to third man where Martin Andersson takes the catch.
Josh Bohannon joins Luke Wells and the lead is 207.
Glamorgan 424 v Northants 185 & 250-8 - Northants lead by 11
Northants are in front of Glamorgan's first innings total so the Welsh side will have to bat again in Cardiff.
Just two wickets to get for the hosts though so how long they will have to bat for is debatable.
Durham 650-8 v Notts 407
Liam Patterson-White in for his 48th (yes 48th) over. He looks understandably weary.
You'd forgive a bit of boredom even. Five singles bring Durham within three of their highest-ever first-class score.
Mohammad Abbas in and Ben Raine eases his second ball into the offside for an easy single, and George Drissell plays a single into the legside.
And there it is. Ben Raine is the man to make history with an umpteenth single.
One more takes us to 650 in the 171st over.
On we go.
Warwicks 186-7 - target 310
Kevin James
Former Middlesex & Hampshire cricketer on BBC Radio Solent
Ethan Bamber is keeping the game interesting.
Ben Brown will be pondering how to break this partnership.
Tattersall c Sibley b Clark 12 (Surrey 512 v Yorkshire 255 & 83-3 - trail by 174 runs)
Jonny Tattersall pushes at one outside his off stump from Jordan Clark and it catches the outside edge.
It goes to Dom Sibley at second slip who takes a good catch to bring and to this stubborn partnership between Tattersall and James Wharton.
That brings Yorkshire skipper Jonny Bairstow to the crease. A reminder he made 89 in the first innings.
Snater c Brookes b Waite 1 (Worcs 358 & 134 v Essex 157 & 93-8)
Eight down and Worcs on the verge of victory - a first of the season.
Matthew Waite has 4-10 with six maidens in 8.3 overs.
Shane Snater his latest victim.
Thain c Roderick b Taylor 23 (Worcs 358 & 134 v Essex 157 & 92-7)
Seven wickets down and a club record-equalling ninth catch for Gareth Roderick!
And no sooner have I finished writing that...
Durham 641-8 v Notts 407
Durham could well be gunning for their highest first-class total - 648-5dec - which also came against Nottinghamshire.
They need just eight more.
Patel c Holden b Gohar (Leics 51-2 - target 102)
Rishi Patel smashes one straight up in the air off Zafar Gohar and Max Holden composes himself well to take the catch.
Very, very faint glimmer of hope for Middlesex. Not much more than that at this stage.
Durham 633-8 v Notts 407
Melinda Farrell
Sports broadcaster/journalist on BBC Hereford & Worcestershire
Clark gave himself some room and allowed the ball to skid onto his stumps.
What an innings from him, it was exactly what Durham needed.
He's in very fine form at the moment.
Leics 51-1 - target 102
Leicestershire move past 50 in the 12th over of this run chase and they're halfway there.
Another 51 runs will see them over the line for their fourth win of the season.
