Matthew Waite finds the edge of Dan Lawrence's bat but the ball is squirted away harmlessly to backward point.

An inside-edged drive to fine leg brings two runs and takes Lawrence to 49.

Daniel Bell-Drummond is off the mark with a flashing drive that scythes the ball over the slip cordon and through third man for four.

Josh Davey bowls with a bit of width outside off stump and Ben Compton leaves the ball.

Maiden over.

The first time that Olly Stone has taken four wickets in an innings for Nottinghamshire. It's only his fifth game, a terrific effort from him.

But Keith Barker was at the crease for less than two hours with an innings that's transformed the game.

What a session - and a day - it's been for Tom Aspinwall!

The young Lancashire medium-pacer records his maiden first-class five-for, taking the final Durham wicket by trapping Callum Parkinson leg before.

Aspinwall finishes with 5-41 and Durham, despite Paul Coughlin's 17 not out, are dismissed for 236 after losing their last five wickets for 23.

Yadvinder Singh continues from the Vauxhall End and Dan Lawrence is forward, turning the ball through square leg for four.

Singh is close to taking the outside edge as Lawrence plays and misses.

Lawrence keeps the strike with a single to third man.

Andy P: Turned on the cricket to watch Barker in action and he was immediately out. Sorry

Ben Compton gets a leg side ball from Josh Davey and glances it neatly through mid wicket for four.

Compton gets away with an inside edge that just evades leg slip for a single.

An expensive over from Nathan Smith as the other Smith (Jamie) drives for four through mid off and gets four more with a swivel pull square off the next ball.

In the next over, Jamie Smith and Dan Lawrence celebrate a 100 partnership in 137 balls and a 300 lead as Lawrence is forward and squeezes an inside edge off Yadvinder Singh in front of square on the leg side for one.

A glorious extra cover drive on bended knee by Jamie Smith brings four more.

Daniel Bell-Drummond sees out the Craig Overton over and now Josh Davey will bowl to Ben Compton.

In theory we have 31 overs left tonight but the overheads are gloomy and the floodlights are on.

Matt Renshaw is in at forward short leg and three slips are in.

Ben Compton gets a single second ball and Bell-Drummond gets a couple of leg byes as the ball runs away fine.

Davey beats the outside edge but the Kent captain survives.

Daniel Bell-Drummond has one ball to face from Craiig Overton, who had his over disrupted by rain.

Ben Compton is eight not out at the other end.

Ben Raine gets himself all tangled up and Tom Aspinwall gets his third.

It's been some start to the evening session.

Tea has come at a shocking time for Durham, they were scoring so nicely, David Bedingham and Graham Clark.

Frustration for Nathan Smith who spears a ball down leg and Dan Lawrence gets a leg bye.

The 200 comes in the 58th over.

Jamie Smith moves to his half century in style with a flowing drive through mid off and a neat checked drive through cover point three balls later, played from the crease.

83 balls and nine fours.

That's his third 50 of the season and he also has one century, having made 155 in the last round here against Warwickshire.

Essex had looked to be relatively comfortable with that second wicket partnership between Jordan Cox and Simon Harmer just before the break.

The pair had put on 44 before Cox fatally missed a reverse sweep off Rob Yates and was bowled.

Simon Harmer resumes on seven not out and his new partner is Shane Snater, facing Rob Yates, who has two balls left in his over.

Lively start to the evening session, with Keith Barker clipping Olly Stone for a boundary and then misjudging the next ball as he tried to hook.

Barker gets a whack on the helmet, so he'll get that checked over - but will hopefully be fine to continue. He's the kind of warrior who would bat - and maybe bowl - on one leg if he had to!
