Ben McKinney stretches to slap a short, loose ball from Jacob Duffy over the covers to the ropes.

Will Rhodes had picked up three from the opening delivery of the over to another one offering width.

Not what the Worcestershire doctor ordered.

92 needed to win. Nine wickets needed to win.

26 behind. Fergus O'Neill has the ball and will see us through to tea.

Single to Tom Haines, nudging the ball leg side.

James Coles plays down the wrong line at one point but the ball dribbles away safely into backward point.

Single to Coles through the off side but that's a very tight and perhaps even non-existent run as Farhan Ahmed picks up sharply from backward point. Coles gets away with it.

That's tea. An encouraging start from Sussex who started 131 behind but Notts have fought back with 3-11, two of them to the off psion of Ahmed and one to Fergus O'Neill.

25 behind now.

Will Rhodes times a drive beautifully to find the rope for a valuable boundary off Tom Taylor, who responds by squaring him up in successive deliveries.

Huge pressure on the Pears bowlers not to deliver any loose balls, as Taylor did first-up with a wide half-volley.

It's a most extraordinary game of cricket on a pitch which has offered bowlers plenty of assistance with lots of lateral movement.

Runs have been very hard to come by and it's probably the slowest outfield I have ever seen.

James Coles is squared up a bit as he defends down the track to see out the Fergus O'Neill over, a maiden.

Farhan Ahmed is into his 11th over with a slip and a silly mid off and Tom Haines is in forward block mode.

The fourth ball is a bit shorter and cut away for one.

Two more to Coles, working the ball to fine leg.

The game is very open, if Somerset can come back after tea and grab a few wickets if will be very interesting.

It would disrupt the Surrey batsmen if they can just find another.

Four runs to Jamie Smith, back and across to flay Jack Leach through wide long off.

Tom Lammonby will bowl the last over before tea and Jamie Smith nearly gets himself in trouble going down the track and the ball beats the outside edge.

He's well forward again to flay through the off side for two to reach 47.

Thick edge over backward point.

Another play and a miss as Smith seems keen to drive at everything.

Tea. A few little alarm bells for Surrey there but the gap is down to 65.

Ben Foakes is 17 not out and Smith remains on 47.

Three wickets lost in the session. Honours even?

Alex Lees taps a single off the final ball of the first over to retain strike.

Tom Taylor will bowl the second over to him.

Alex Lees and Ben McKinney are first in the firing line for Durham as Jacob Duffy tries to make an early breakthrough for the Pears.

We have had an early tea at Worcester so this one is going the distance today, one way or other.

In theory Durham only need 0.46 an over to win it, if they want to use the next two days.

Ben Cox's brave knock comes to a close as he is bowled for 53 by Ajeet Singh Dale and we have a thriller on the cards at Bristol.

Leicestershire lead by 10 on first innings, with both sides showing immense grit to secure a batting bonus point after losing a glut of early wickets.

This one should be fascinating across the next 24 hours.

Tom Lammonby is on for another spell of left arm medium pace and a Ben Foakes cut is picked up at cover point for no run.

Maiden from left arm spinner Jack Leach at the other end.

Tom Alsop is off the mark with four runs driven to long on off the bowling of off spinner Farhan Ahmed, who has taken both Sussex wickets to fall in this innings.

Nice shot, waiting for the flight on the ball to dip and pushing through the line.

32 behind.

Martin Emmerson

I suggested a little earlier Worcestershire should declare because they could well have more than enough runs on this track.

30 wickets have fallen in five sessions for 379 runs. But, they were bowled out in 23.5 overs for just 81 runs. It's their lowest total against Durham and the sixth lowest score by a county side against them as well.

The target is 108 runs, which doesn't sound much, but on this strip that's the equivalent to 300. I don't think this game is over by any stretch of the imagination.

I did suggest on air - this morning - the match would end today and I stand by that one. Unless bad light proves me wrong later.

Melinda Farrell
Sports broadcaster/journalist on BBC Hereford & Worcestershire

I just don't know what's going to happen... if one Durham player comes out, gets one or two partnerships of 25-30 runs...

But in that first innings they weren't able to last out there as long as Worcestershire did.

The pitch has been getting harder to bat on, it seems.

it's very difficult to tell and make predictions.

Runs for Ben Foakes, showing the full face of the bat to drive Migael Pretorius down the ground for his first four.

Jamie Smith gets Surrey to 200, driving left arm spinner Jack Leach to long off for a single.

Adrian Harms

It was a little ambitious trying to sweep him away on the leg-side.

Sussex are still 38 behind now, I think Tom would admit that it wasn't the best shot to play in the circumstances.

He's now picked up two lbw dismissals, the game's got a completely different complexion on it now.

Notts 300 v Sussex 169 & 93-1

Tom Haines has been hit on the head by a Josh Tongue bumper and we have a pause in play while he's checked over by the physio.

The good news is he didn't flinch and he looks reasonably calm.

He's going to bat on. Thank goodness for helmets.
