A frustrating wait due to the heavy rain of yesterday, and the resulting wet outfield, meant only 10 overs were possible before lunch.

Leus du Plooy looked slightly unimpressed by his lbw as he walked off rubbing his back hip but showed no form of dissent.

It was a crucial breakthrough for the hosts just after the fourth-wicket partnership passed 150.

Kane Williamson (126 not out) looks in imperious form but Gloucestershire will still be rueing his drop early at slip.

The dull passage of play with the Kookaburra, which usually starts after 15 overs of the ball's life, has begun and is mercilessly only 18 overs from the end before the second new ball becomes available.

A dismal morning for Somerset, as they lost four wickets in adding just 58 to their overnight 338-4, sacrificing the initiative in the process.

The Notts seamers bowled well, but the pitch is as placid as ever, and the wickets were all down to batsman error.

Like Tom Abell before him, James Rew fell into the most obvious of traps, caught down the leg side trying to hook a short ball from Dillon Pennington, while Tom Banton and Archie Vaughan were both caught behind off loose shots.

Somerset seemed caught in two minds over whether to pile up the runs or chase batting bonus points, and ended up achieving neither.

Div One

Durham 153 v Surrey 322

Gloucestershire v Middlesex 275-4

Kent 18-0 v Leicestershire 471

Lancashire 34-1 v Glamorgan 261

Northants 48-1 v Derbyshire 377

Ethan Brookes bowls out a maiden and Worcs will be very happy with their morning's work having taken 4-67 in the opening session.

The slumped shoulders of yesterday, buoyed by two wickets last night, have risen with each celebration.

There is still a long way to go to win this match and plenty of bad weather forecast (particularly tomorrow which looks wet) but a decent effort from the hosts.

Charlie Allison (77) and Michael Pepper (33) have pushed on well towards lunch and it is already looking like Essex will not lose this game.

Taking wickets has proved difficult for the visitors on a good batting strip but with a decent line-up (albeit minus Simon Harmer) they look likely to have plenty to defend.

A curate's egg of a scorecard for Somerset, a bit similar to Leicestershire's even more remarkable first innings card last week.

From 0-2 to then a record breaking fourth-wicket-partnership (313) including a career-best for Tom Abell, and then a collapse this morning with barely any contribution from the other eight Somerset batters.

Third top score for Somerset so far is Craig Overton with 18*!

Notts have bowled well this morning, as they did at Taunton just a few weeks ago, showing why they have been challenging at the top of the table most of the season.

It was a slow full toss.

It's a big lead for Surrey, five wickets for Ben Raine and a good position for them.

They've added 182 this morning, it'll all be about Durham batting after lunch.

Two minutes before the risk of an extra half an hour being taken, Surrey's innings ends and Ben Raine gets a deserved five for 72 with five maidens.

Jordan Clark was even more aggressive with just number 11 Dan Worrall for company, a slower ball low full toss smashed to long off to end his top score of the match knock, 82 off just 76 balls.

Two clever cutters from Raine earning the last two of his michelle.

Gurinder Sandhu is in his deilvery stride at the start of his seventh over but Imam-ul-Haq pulls out at the last minute as a huge seagull flies right across his eyeline.

Don't know about distracting him that looked big enough to take him off as lunch. It settles menacingly over on the scoreboard on the leg side boundary.

I don't think he's hit it, it looks like it's come off the knee pad.

We're in the territory of delayed lunch now.

Jordan Clark is looking imperious.

Perhaps enjoying his proximity to his Cumbrian home and enjoying having his brother watching him bat from close proximity too.

He is 67* at more than a run a ball.

Well bowled Lyndon James and another good take from Joe Clarke.

Disappointing from Archie Vaughan, it was a nothing ball.

Martin Emmerson
BBC Radio Newcastle

It was a perfect delivery from Raine.

He strikes the off stump, it's been the story of this match.

I wonder if we will get into the territory of the new ball?

Finlay Bean's exit has brought Yorkshire's overseas signing Imam-ul Haq to the crease and he starts his innings with an on-drive four on his second ball.

The Pakistan international was due to start here at Scarborough against champions Surrey but was prevented from playing due to visa issues.

With those now resolved the stage is set for him to hit the ground running and he moves to 12 with a cover drive and square cut off Danny Lamb.
