Adam Lyth edges Luke Procter on a flashing drive, but the ball goes well wide of third slip for four runs.

Lyth pushes the last ball through the covers for no run and that's lunch.

Yorkshire continue to tighten their grip on the second promotion spot but will no doubt hope nothing extraordinary happens with their promotion rivals Middlesex, who have just started their match against Sussex at Hove.

Josh Bohannon and Rocky Flintoff survive until the interval, but they'll have a good deal of work to do this afternoon to keep alive Lancashire's hopes of staying up.

Very much Worcestershire's morning, having added another 61 to their total before removing both Lancashire openers cheaply.

80 overs in the day's play.

Sussex bring in Fynn Hudson-Prentice for Bertie Foreman since the last round.

Just the one change for Middlesex too, with Tom Helm coming in for Noah Cornwell.

Mark Stoneman and Ethan Bamber will be making their final appearances as Middlesex players.

Bamber will join Warwickshire next season. Nothing definite for Stoneman yet but he's surely too good a player not to return to first team cricket next summer.

Sam Robson and Mark Stoneman will open the innings.

Robson will face Ollie Robinson.

Shoaib Bashir gets off the mark with a chipped push just past Felix Organ, Somerset do last the over so we will now play until the final wicket falls or 13:10 BST.

Not a great start from Luke Procter.

His third ball is full outside off and driven through cover for four and four more runs come off the fifth ball, driven through the same region.

That takes Yorkshire to 50 in 12.5 overs.

Ben Sanderson thought he had James Wharton out but that ball appeared to bounced off the boot and it landed short of Gus Miller in the slips.

Just the one over from Justin Broad at the other end and now Northants captain Luke Procter will have a bowl before lunch.

Technically Lancashire could pick up 22 points from this game, rather than the full 24, and stay up. That equates to a first-innings score of 350 inside 110 overs, and then beating Worcestershire.

But they'll need Warwickshire to make less than 250 (zero batting bonus points) in their first innings at Notts and then lose, thus sending the Bears down.

You with us?!

Nottinghamshire have opted not to have a tilt at maximum batting points, concentrating instead on denying the Bears another point for bowling.

It's job done in that regard, with the Bears putting four men around the bat for the 110th over from Danny Briggs but Farhan Ahmed plays him sensibly and Warwickshire will have to settle for just two bowling points.

Sussex have won the toss and chosen to bowl first.

We have a minimum of 80 overs in the day's play.

Middlesex need a big score to stand any real chance of beating Yorkshire to the final promotion spot.

Jack White has already had bad luck with injuries this season, in which he has played only four Championship matches (including this one) following a succession of painful setbacks.

Sadly, he will not be able to complete the eighth over of the innings and will leave the field.

Justin Broad completes the over and Wharton defends the ball into the off side.

Yorks 32-1 v Northants 147

James Wharton works a ball from Jack White into the on side for a couple of runs to move to six.

An attempted straight drive hits White on one of his legs in his follow through.

We might be pausing for a while.

Ben Sanderson finds a bit of extra bounce and James Wharton blocks almost with the splice of the bat to see out the over.

More shape back into the left-handed Adam Lyth, facing Jack White.

But the third ball is too full outside off and driven expertly through extra cover for four.

Four more driven with an emphatic flow of the bat through cover.

He'll keep the strike with a leg glance for one.

Four slips in for Sanderson and Lyth bottom edges a forcing back foot drive past his stumps for a single.

Shot! Wharton picks up four, driving down the ground with perfect balance. That's a stylish way to get off the mark.

A lovely touch at New Road, as the Worcestershire players line up in a guard of honour for Pears stalwart Joe Leach.

Leach is playing his final first-class match before retirement and, given the state of the game, this might well be the last time he opens the bowling for Worcestershire.

Lancashire have 83 overs left today - and they need as many runs as they can get in that time.

50 for Somerset skipper Lewis Gregorypublished at 12:04 British Summer Time

Somerset 136 & 149-7 v Hants 196

Double change for Hampshire with James Fuller and Felix Organ into the attack for the first time this innings.

Organ's first ball is a little short, and with five men on the rope, Lewis Gregory eases a single for a crucial 50 in this low scoring thriller.

Eight fours and a six for Gregory, just 38 balls needed for his half century.
