Tom Haines gets a bit stuck in the crease as he tries to cut Mahipal Lomror away and misses.
In theory there are still more than 40 overs left in the game so the draw is not a certainty just yet.
Durham v Middlesex 246-8 - target 424
Lovely thumping pull shot from Tom Helm gets him four more off Kasey Aldridge.
Helm has a bit of recent previous against Durham.
Only last month Helm came in at number nine and helped Luke Hollman add 79 as Middlesex turned around a seemingly-lost cause to beat Durham and reach the One-Day Cup final.
That match will take place at Trent Bridge on 20 September against Leicestershire.

Durham v Middlesex 232-8 - target 424
That is a delivery to catch your attention!
Super lifter from Kasey Aldridge to Tom Helm that just about misses bat and face.
Then he goes fuller next ball and strikes the pads. Not out, probably sliding down leg or over the top.
Helm then works one away for a couple through leg.
And Helm follows up with a fine off-drive off the back foot. Four runs.
Sussex 393 & 98-1 v Surrey 321 - lead by 170
Some turn and bounce for Mahipal Lomror but his fourth ball is too wide and dabbed away by Charlie Tear for one.

Singh c Andersson b Randell 59 (Derbys v Kent 129-6 - target: 434)
Image source, Getty ImagesWhere did that come from?
Kent were just beginning to score more fluently and had run a number of threes because of the slow outfield. Ekansh Singh did then find the rope, but in the same over he has now departed.
This ball from Brett Randell popped up off the surface and got up on the all-rounder, who ends up helping it to Martin Andersson at backward square leg - it is a good catch. Singh is gutted.
Derbyshire need four more wickets for victory and are now into the tail.
Sussex 393 & 96-1 v Surrey 321 - lead by 168

Sussex 393 & 96-1 v Surrey 321 - lead by 168
Still one slip in for Rahul Chahar, who continues from the Sea End as a chorus of gulls can be heard cooing over the ground.
Plenty of width and Charlie Tear safely shoulders arms.
Tear plays and misses with a forward defensive and the ball fizzes through to keeper Ben Foakes, who whips off the bails.
Tear was in his crease.
Another maiden over for Chahar.
Durham v Middlesex 225-8 - target 424
BBC Radio Newcastle's Martin Emmerson has been predicting a 2pm finish today at the Riverside.
Good effort Martin, but we still have a bit more cricket left.

Durham v Middlesex 225-8

No, it's over the ropes for six.
Duke goes for another pull shot off the final ball of the over but knocks it into himself. Luckily, it drops straight to the ground with no damage to ball, bat or wickets.
Sussex 393 & 96-1 v Surrey 321 - lead by 168

The second wicket partnership is worth 82.
Rahul Chahar's turn to try and break it. Tom Haines is forward, glancing to leg but doesn't get the ball away this time.

A single driven through wide mid off to end the over.
83 partnership now.
Durham v Middlesex 219-8 - target 424
Callum Parkinson whizzes through a maiden over to Tom Helm.
He has figures of 3-20 from 11 overs and captain Alex Lees may do well to get the ball out of his left-arm spinner's hand.

Division One's bottom club were bowled out for 123 in an extended morning session, chasing a target of 178, as Olly Stone took 6-28 for the home side.
"We have moments in games when we're really quite good but not often enough. We just have to face that and front up," Domingo said.
"At the end now we need a bit of a miracle to stay up so we have to play better cricket. Things can look dark but we can definitely compete again."
Notts moved back into second place with 22 points and Stone said: "We all knew coming in that this week was massive and the way the crowd got behind us was outstanding."
Hampshire must fear losing some of their top young talent with relegation now almost a certainty...who will Surrey come calling for?
