A productive first over takes Surrey's second-innings total past 200 at The Oval. After a leg bye from Tom Bailey's opening delivery, Sam Curran plays him away for three runs before Ben Foakes takes two from the next delivery. Graham Onions will open up at the other end.

It's almost time for action at The Oval where Division One leaders Surrey are 161 runs ahead with six wickets standing. Sam Curran and Ben Foakes are the not out batsmen.

This game is very much in the balance and a good first session by the Lancashire bowlers could undermine Surrey's hopes of a seventh win of the season.

We brought you news of Glamorgan's defeat by Durham earlier, and there was further disappointment for the Welsh county yesterday when batsman Aneurin Donald's decision to leave for Hampshire was confirmed. Here's what chief executive Hugh Morris had to say about it.

Ben Cox eases Josh Poysden backwards of square for one.

Moeen Ali drives to mid on for three.

Two slips in place now for the leggie and Cox gets a single through point.

Moeen Ali defends and the players walk off for lunch. He's 190 not out after a record breaking second-wicket stand for the Pears against Yorkshire. Might he be a contender for England if Jonny Bairstow can't play at Southampton?

The lead is 263.

Surrey spinner Amar Virdi is relishing the learning experience of a day-night match against Lancashire at The Oval, where the Division One leaders will resume with a 161-run lead in about quarter of an hour.

The off-spinner took 2-54 in Lancashire's first innings and admits he is still adjusting to bowling with a pink ball.

"I think the only thing it is comparable to is bowling with a white ball. I mean obviously it’s a Kookaburra so the seam is slightly different from the Dukes, but it’s not too different, it just goes a bit soft so in the hand it can feel a bit bigger at times," he told BBC Radio London.

"I think we’re in quite a good place. (We want to) Try and bat for as long as we possibly can and then take the game from there. We want to be controlling it like we are now."

Somerset avoid further loss in the final five overs of the morning session at Taunton and remain in a good position despite the loss of four wickets during the morning session. They are 260 ahead and any lead over 300 will mean Essex have to bat very well to win this game. Tom Abell is 16 not out, with partner Steven Davies on five.

The seagulls are in full voice here in Scarborough as Adam Lyth gets one to turn and Ben Cox knocks it past short leg for one.

Is that lunch? No, one more over.

Declaration just before tea maybe?

Maiden over.

Luke Fletcher bowls to Gareth Berg, who shuffles across the line and is struck on the pad.

Big appeal from the bowler but the umpire says no.

Berg edges to square leg for one.

Well bowled! Fletcher beats Liam Dawson's defensive prod.
