Are there the odd signs of frustration creeping into the body language of Lancs fielders? Maybe just a touch.

James Sales and George Bartlett continue to row against the tide of this match with the latter 41 from 44 balls and Sales 24 with the partnership now 67.

The ball is a couple of overs shy of raising its bat at 50 and batting is looking easier for the set pair.

Double teapot from Ben Raine as he thinks he's trapped Zak Crawley infront but his huge and concerted appeal is turned down.

The England man gets the benefit of the doubt, was it a touch high? Raine certainly doesn't think so, and it looks like a stroke of luck for the Kent opener.

Ben Raine is into the attack for the first time but his first delivery is cut away by Sam Northeast to the cover-point boundary.

Zak Crawley moved to 18* at the end of the previous over from Matty Potts with a textbook cover drive.

16 from 20 balls between these two. If they just can keep that going for another 45 overs we'll have ourselves a finish...

Ben Slater has put the pressure behind him and produced a gorgeous back-foot cut to the backward point boundary off Alfie Ogborne and now a lovely pull to the rope off Craig Overton at the start of he next over.

Overton replies by beating the edge as Slater comes down in defence.

Absorbing stuff five overs into the final innings.

Exactly the start Yorkshire would have been hoping for after Glamorgan declared at lunch.

Adam Lyth cover drives Timm van der Gugtan for four and then square cuts the next ball to the point boundary.

He is 41 not out and Finlay Bean has 21.

Alfie Ogborne has been a coat of varnish away from the breakthrough three times in this over.

Ben Slater is not having a very comfortable time at all.

Haseeb Hameed picked up the first boundary of the innings with an inside edge which flashed past his own stumps and away to the fine leg rope.

That's old-school Zak Crawley, leaning confidently on a widish one from Kemar Roach and galloping three runs with Sam Northeast as the ball is stopped just inside the rope.

Northeast gets off the mark from his seventh ball with a nice cut to the backward point boundary two balls later but survives an almighty scare from the next ball as the ball flicks off his pad just outside the line.

Sussex start the summer with a win at Grace Road as Ben Green pulls a short ball from Henry Crocombe and Fynn Hudson-Prentice takes the catch safely at square leg.

Pace bowler Crocombe finishes with 4-36 and career-best match figures of 9-69 after the visitors had been held up during the morning by a stand of 103 between Ben Cox (60) and Stevie Eskinazi (54)

Sussex skipper Ollie Robinson chose not to bowl himself on the final day, but in the end was not needed.

Having begun the season on -12 points because of their financial issues, they move into the black at the first attempt.

Haseeb Hameed and Ben Slater are under the pump here.

The openers have played and missed at Alfie Ogborne and Craig Overton several times in the opening two overs.

Tense stuff at sun-soaked Taunton.

James Sales had a lucky escape a couple of overs back when a late defensive block saw the ball dribble back towards the stumps from a delivery from Tom Bailey.

Fortunately for him it missed and now he is up to 16 and his partnership with George Bartlett up to 48.

In losing situations like this it is important that sides try to take every single positive they can with next week's round two in mind and the way these two have batted since lunch in one such plus.

Haseeb Hameed and Ben Slater open up for the Champions, with Craig Overton sending down the first over.

A hair under seven an over required. Surely they'll be content to bat time and not worry about the nominal target?

Pretty suffocating stuff from Matty Potts, who has allowed just one run from his first three overs.

Zak Crawley and Ben Compton are, understandably, playing it safe.

Warwickshire have taken the new ball and having been frustrated all day so far this is surely their last chance to make something happen.

Smith and Lawrence have now put on 151 for the fourth wicket
