The teams are back out in the middle at Headingley and Adam Lyth cracks Jacob Duffy's second delivery for four.

With two complete days left, we wonder what kind of lead Yorkshire might be thinking about before declaring.

But that is putting the cart before the horse - maybe Worcestershire will bowl them out in which case the question is irrelevant.

Well batted Tom Haines!

He reaches a century in some style as she sends a Jack Leach delivery back over the England bowler's head straight down the ground for four.

Wonderful stuff.

Four runs for Marcus Harris, waiting in the crease to guide a full, wide ball from Raphy Weatherall through point.

He's on 34 and now Calvin Harrison will bowl to Keaton Jennings on 49.

The lights are on at the Riverside and the umpires have had a preliminary chat.

Colin Ackermann sends down a maiden over. There are 15 more scheduled in the day after this one but will get all of them?

A silly mid on and a slip in for spinner Liam Dawson as Dom Sibley is forward to defend.

Immaculate block. Head right over the ball.

Sonny Baker is bowling at the other end and Ollie Pope gets a single driven into the off side.

One more for Sibley guided to deep backward square and he's on 40.

The answer to our question (5:23 entry) is no, Jonny Bairstow will not ask Worcestershire to bat again today..

Yorkshire will therefore begin their second innings with a 294-run lead and 19 overs to face this evening.

Calvin Harrison bowls to Marcus Harris and a quicker ball zips past the leg stump for four byes.

The next ball is driven firmly past Raphy Weatherall at extra cover for four runs.

He keeps the strike with a single down the ground.

Weatherall is back in the attack from the Statham End.

A big moment for Kai Smith as he steers Colin Ackermann for a couple and reached a maiden first-class 50 from 86 balls.

It's only his second Championship appearance so this has been a great effort for his team, who were 157-6 when the last wicket fell.

Sussex 294 & 204-1 v Somerset 201

Tom Haines moves on to 93, with Tom Clark on 11.

Sussex's lead moves near to 300 and we have about 11 overs remaining today.

An unusual way to bring up the 50 partnership for the third wicket between Keaton Jennings and Marcus Harris.

Harris pushes Liam Guthrie into the off side and the return throw from Luke Procter beats the on side field and runs away for four.

So five runs to Harris and the 50 partnership comes in 75 balls.

single to Jennings next ball and Harris gets four steered through backward point from the crease.

That's the Lancashire 100 in 35 overs.

Glamorgan's task at Bristol has gotten a bit harder.

Sam Northeast reached 50 but then edged Ajeet Singh Dale into the breadbasket of Cameron Bancroft in the slips.

The weather bubbling up in the south west might be Glamorgan's best hope of getting out of today without too much further damage at Gloucestershire.

No news from Kent is good news for Middlesex. Ben Geddes has 37 and his side lead by 173 in their second innings with five wickets remaining.

Martin Andersson is into the 70s for Derbyshire at Leicestershire but are still 60 shy of the follow-on target with three wickets remaining.

Durham 387 v Warwicks 208-6

Michael Booth edges a ball from Colin Ackermann, Matthew Potts dives at first slip but it just brushes the ends of his fingers.

Notts 347 v Essex 250-5

It's finely poised here with 20 overs remaining.

Essex trail by 97 and have five wickets in hand.

They've just picked up their first batting point and it's all to play for.

Single to Sibley pushed into the on side and Ollie Pope gets away with a flashing drive that scythes the ball wide of the two slips and away for four runs.

Pope gets one more run with a confident front foot drive through cover and Surrey continue to cruise along at a tad beyond four runs an over.

Warwickshire's total has passed 200 and Durham have reintroduced the off-spin of Colin Ackermann following his solitary over before tea.

A tidy one there from the former Leicestershire all-rounder. Kai Smith is 40 not out and Michael Booth has 11 - they have added 47 since the dismissal of Ed Barnard.

Liam Guthrie is in the attack once again and Keaton Jennings moves smoothly through the 40s with fours driven down the ground on the front foot and lashed through cover on the back.

Nine runs off that over and Jennings is on 47.

Good news England fans - look who's been doing a bit of practice bowling on the outfield at the Riverside.
