There's a hush at Chester-le-Street. The home fans know this one is done and dusted.

Rawlins c & b Wood 42 (Sussex 98-3, target 141)
Brilliant pace bowling from Mark Wood.
The England man fires one in at the chin of Delray Rawlins and the young all-rounder can only fend it up into the air. Wood takes the simplest of catches.
Durham are just about clinging onto this game.

More punishment from the Sussex batsmen.
Ben Whitehead bowls a full toss and Laurie Evans belts the spinner through the leg-side for four.
The Sharks need less than a run a ball now. 56 required off 59. Oh, it's a no-ball as well.

So, a nice and simple equation at the halfway point - the Sharks need 60 off the last 10 overs.
It should be a piece of cake from here.

Notts and England bowler on BBC Radio 5 live sports extra"It was a chance you'd have expected him to take.
"It came at him quite flat, you'd take nine out of 10 of those and that was the one.
"But when you're defending a low score you have to take half chances and all the chanes you can."

Oh wow, Nathan Rimmington has shelled a great chance.
Delray Rawlins smacks Ben Whitehead towards long off where Rimmington spills it. It was a comfortable height but it bounced off the Aussie.
