It's an emphatic 23-point win for Surrey in what could have been a tricky fixture.

But Durham haven't shown the best of themselves this week and are very well beaten.

Surrey are now guaranteed at least a 12-point advantage over Somerset ahead of their final game next week at Essex.

All eyes now turn to Old Trafford because a third successive Championship title will be sealed if Somerset don't chase down that big target against Lancashire.

Two overs to go until tea.

Liam Dawson is on for a bowl and has a silly mid-on to Jake Libby, but the batter gets that one away for four runs.

A thick edge from Rory Burns earns a streaky boundary to third man before Dom Sibley turns a single to deep square.

One hit away now for Surrey.

Then even closer as Chemar Holder oversteps.

And then Burns flicks through midwicket for two to see Surrey home.

It's taken them only five overs to mop up this little target and they win by 10 wickets.

It’s gettable. It’s not an out of sight target which perhaps it could have been.

It would need a monumental effort from the Pears but with plenty of time left in the match, we still have an intriguing contest on our hands.

Northamptonshire would have hoped to have the game wrapped up by now.

But they're out after tea with 137 to chase, which needs a little work.

33 overs left tonight, plus potentially eight more for the extra half hour.

So 3.34-an-over needed to get the job done tonight.

Can Leicestershire take a few with them?

Rory Burns and Dom Sibley run singles either side of the wicket before James Minto gives Sibley a leg stump half-volley that he clips between long leg and deep square for four.

Minto then sends a wide way outside off and edge from Burns to third man moves Surrey into double figures.

Burns then rocks back to pull Minto for four through midwicket and Surrey are halfway there already.

Hampshire will feel that (Roderick) is a very big wicket indeed.

Just a hint of movement there.

Roderick was basically on the Bakerloo when the ball was on the Central.

He rarely gives it away Roderick, he’s a gritty cricketer.

Anthony Gibson

"The immediate priority for Somerset is to get through to tea without any further damage."

Too much width from the pacey Anderson Phillip and Tom Abell is under way with four, cut away to the point boundary. Two overs till tea.

Archie Vaughan tries to pull a short one from Anderson Phillip and a thin edge flies away for four via his helmet.

The youngster must have a mandatory concussion check, but he's fine.

A little morsel for Surrey to take in after tea.

They will hope Rory Burns and Dom Sibley can see it away without loss.

Somerset 109-1 - target 393

Big moment for Archie Vaughan as a single off Luke Wells takes him to a maiden first-class 50 from 84 balls.

He's been beaten a few times, but this has been a highly promising innings by the 18-year-old.

Somerset will be hoping he can keep this going.

Somerset 106-1 - target 393

Anderson Phillip bounces Tom Lammonby and a top-edged pull flies over the keeper for four.

Lammonby and Archie Vaughan came together when Andy Umeed fell to the second ball of Somerset's innings and now have a century stand.

The boundary takes Lammonby to 48 not out and Vaughan has 49.

A maiden from George Hill and just 18 added in the last seven and a half overs since the departure of Colin Ingram.

No urgent need to do anything but hold on to your wicket for the hosts but Yorkshire will want another break before tea.

Jake Libby survives an lbw shout from Muhammad Abbas early in the Pears reply.

Abbas had a great opening spell in Worcestershire's first innings and is looking dangerous again.
