D2 leaders Notts beat Leicestershire on day three
Yorks 0-0 (target 302 v Lancs)
The pressure now on Yorkshire debutant Fin Bean.
He made a good impression in the first innings and he will face Will Williams at the start of the second over.
Three slips are in place.
Durham 13-0 (target 298) v Derbyshire
A lively start to Durham's second innings, with Michael Jones crashing three boundaries from Nick Potts' first over.
In theory, no reason why Durham shouldn't have a tilt at this target, with 85 overs still to be bowled - but it's Derbyshire whose need for victory is more urgent as they bid to boost their promotion chances.
Yorks 0-0 (target 302 v Lancs)
Would you believe it.
Tom Bailey finds the edge of Adam Lyth's bat with his first delivery, but Josh Bohannon drops the catch.
Lancashire can't afford many of those if they are to win the game.
Somerset 5-0 (target 375 v Gloucs)
We are back in business at Taunton and Imam ul-Haq cover drives a swinging half-volley for four in David Payne's opening over.
Remember these teams are the bottom two in Division One so a win is vital - but especially so for Gloucestershire, given the number of points they have to make up.
Glamorgan 295 v Worcs 454-9
Well, it looks as though the contest at Cardiff is still alive as Glamorgan fall short of the follow-on target.
Michael Hogan is last man out, slapping a Dillon Pennington full toss to short midwicket where Jack Haynes takes a diving catch.
Chris Cooke finishes unbeaten on 51 and, to nobody's surprise, Worcestershire have asked the home side to bat again, 159 behind.
Glamorgan 293-9 v Worcs 454-9 dec
Never mind two batting points - Glamorgan are now eyeing a third, with Chris Cooke and Michael Hogan rattling along nicely.
Cooke has just carved Ben Gibbon to the boundary to bring up his fifth half-century of the season from 96 balls, while Hogan straight-drove the same bowler for six.
The home side need another 12 to avoid the follow-on and that, you feel, would seal this game's fate as a draw.
Lancs 276 & 280-5 v Yorks 255
Only ones and twos from Jonny Tattersall's over but Lancashire decide that with the lead now over 300, it's time to call a halt.
Steven Croft is left five runs short of 50, while Dom Bess' final figures for Yorkshire are 3-84.
5 Live commentator Kevin Howells says Yorkshire's over rate at the time of the declaration was -1, so that may cost them a point.
The White Rose will need to score 302 to win.
Lancs 276 & 274-5 v Yorks 255
A cute reverse sweep by Steven Croft, deliberately played fine, brings him another four off Dom Bess.
He is 41 not out and Lancashire lead by 295.
Derbyshire 306 & 214-9 v Durham 223
Image source, Getty ImagesBen Raine finishes with 5-43 as Nick Potts swings one into the hands of third man - and that's the end of the Derbyshire innings, with the declaration following immediately.
That means Durham will need 298 to win, with 87 overs scheduled.
Lancs 276 & 260-5 v Yorks 255
George Lavelle's innings last just three deliveries.
He tries to hit 'demon' spinner Jonny Tattersall over the top, but doesn't get hold of it and Will Fraine takes a good catch moving backwards at long-on.
The Lancashire lead is 281.

Lancs 276 & 259-4 v Yorks 255
Steven Croft sweeps Jonny Tattersall for one to post a 50 partnership with Dane Vilas.
But it comes to an end on 57 as Vilas makes room to try and cut, but it's too close to him for the shot and he is bowled.
Derbyshire 306 & 212-8 v Durham 223
First success of the morning for Durham as Ben Raine rips out Anuj Dal's off stump and Derbyshire are eight down.
The question is how long the home side will continue batting? Their overall lead is 295. And the weather forecast later is not promising...
Somerset 248 v Gloucs 343 & 279-7 dec
Only four overs bowled by Somerset this morning before Gloucestershire declare, setting the home side a target of 375.
David Payne finishes 17 not out, with Tom Price on eight.
Sajid Khan has the best figures of the home side's second innings, 2-69.
Lancs 245 & 254-3 v Yorks 255
Dane Vilas finds the backward point boundary from the final ball of the latest Dom Bess over.
Jonny Tattersall brings himself on and his opening delivery is a full toss which is put away by Steven Croft.
Croft is 30 not out, Vilas has 25.
Somerset 248 v Gloucs 343 & 278-7
Another maximum by David Payne, who holds the pose after lifting Jack Brooks over mid-wicket.
Gloucestershire now 373 in front.
Glamorgan 268-9 v Worcs 454-9 dec
Worcestershire collect their third bowling point and Ben Gibbon snares his fourth wicket, with Ajaz Patel caught behind.
Good catch by Ben Cox, diving away in front of first slip, and last man Michael Hogan arrives at the crease to join Chris Cooke. Still 37 needed to avoid the follow-on.
Lancs 276 & 238-3 v Yorks 255
Steven Croft swats Ben Coad through mid-wicket for four.
Yorkshire then drop Dane Vilas before the Lancashire skipper collects the second boundary of the over by crashing the ball over mid-on..
The lead is 259.
Kent 164 & 137-8 v Essex 573
Promising news for Essex fans... there's a pitch inspection planned for 11.30.
The visitors need just two wickets to wrap up an innings victory over Kent.
Somerset 248 v Gloucs 343 & 269-7
Gloucestershire's lead is now over 350.
And David Payne adds six more by hoisting Josh Davey back over his head for a towering six.
Davey tries a yorker but it's wide of off stump and Payne is able to edge it away to third man for four.
