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.

With Nottinghamshire continuing to accumulate runs here, it's the visitors who might just be getting a tad nervous if Lancashire bat strongly at New Road.

Warwickshire have picked up two bonus points with the ball so far, but they've only got five overs left to take two more wickets and make it a full complement.

If that doesn't happen, the Bears might need a few points when they bat to make absolutely sure they can't be caught by Lancashire.

Ben Sanderson is bowling round the wicket to the left-handed Finlay Bean, who leaves the ball outside off stump.

Bean picks up a single to fine leg off a thick inside edge going forward to defend.

Sanderson switches to over the wicket and beats Adam Lyth outside off stump.

Finlay Bean miscues an attempted glance to leg and gets a thick edge off Jack White to deep third and runs three.

White adjusts his line slightly and Lyth blocks into the off side.

Single to Lyth to square leg.

The last ball of the over is played to deep third and Saif Zaib beats the ball to the rope. Three runs.

Well, well!

With little riding on this Division Two match and the forecast not looking great in Cardiff on Sunday, both captains have had a chat and decided to make a game of it.

Glamorgan declare their first innings on 381-4, both sides then forfeit an innings, meaning Gloucestershire will chase 382 to win.

Love it!

Lewis Gregory is living a bit of a charmed life, fortune favours the brave as they say.

He slashes Mo Abbas just between second slip and fourth slip again for four having chipped one just between long off and deep extra cover off Liam Dawson previously.

Somerset now past their first innings total, just.

Adam Lyth is forward to Ben Sanderson, pushing into the off side.

He's off the mark second ball, tucking a leg side ball fine for one.

Finlay Bean leaves outside off at first and then runs his second ball behind backward point on the front foot for two.

Jack White will share the new ball from the Howard Stand End and immediately gets the ball to jag in sharply from the seam.

Lyth almost overbalances as he digs the ball out into the off side.

An LBW shout is turned down later in the over. Adjacent but probably seaming a bit too much down leg.

The last ball of the over is full and tucked round the corner for two.

Logan van Beek misses out on a half-century, falling for 48 as George Balderson bowls him with one that kept low.

That's the end of the Pears' first innings, but they'll be pleased with their efforts this morning. Teenager Jack Home finishes unbeaten on 13, having helped Van Beek to add 26 for the last wicket.

For Lancashire, it's now time to strap on their pads and go hard with the bat if they're to have any chance of saving themselves from relegation.

Brett Hutton secures a fourth batting bonus point for his side, steering Ed Barnard to the cover boundary - and then pulls the next ball for four more.

With nine overs remaining until the cut-off for bonus points, Nottinghamshire might feel it's worth their while to throw the bat and try to reach 450.

Notts are already in a position where it'd take some doing for them to lose this game - and a draw keeps them up, whatever Lancashire do at New Road.

Century for Tom Westleypublished at 11:43 British Summer Time

This has been an incredible innings by Essex captain Tom Westley.

The former England batter goes to his century with a 22nd four!

102 not out, 88 of which have come in boundaries.

That must be up there with the most fours scored in a hundred?!

More frustration for Lancashire as the Pears' tail continues to wag, with Logan van Beek and Jack Home thwarting their hopes of a quick finish to the innings.

Their efforts with the bat are eating up valuable time for the visitors, who badly need to get out there and score quick runs as soon as they can.

Yorkshire have already extended their lead over third-placed Middlesex to 18 points and of course their promotion rivals are still unable to take the field at a damp Hove.

They're unlikely to do so till around 13:00 BST at the earliest, following a planned early lunch and inspection at midday.

Adam Lyth and Finlay Ben will open the innings for the hosts.

Lyth already has over 1000 runs to his name this season and will take strike first, facing Ben Sanderson.
