A great unknown in the match, given we've not had a single over of spin, is what Farhan Ahmed might do if he gets a bit of a bowl after tea?

You don't know, it's been a seam dominated game and continues to be.

Glamorgan trail by 168 runs at the end of a session in which they lost just two wickets and they will be pretty happy with that.

Conversely Middlesex will be a little frustrated that a game they expected to tilt their way that session has refused to.

Nottinghamshire's bowling attack beginning to become a little ragged.

Lyndon James is pulled up for a no ball, which in truth could have also been a wide.

The hosts still trail by 229 runs, however.

We have spin from both ends now as Tom Prest comes on to bowl.

It's starting to look rather gloomy over The Utilita Bowl - and so far we've not seen a lot of turn on this pitch.

Somerset still trail by 67 runs with nine wickets remaining.

An absolute beauty from Kasun Rajitha beats Brett D'Oliveira.

Worcestershire move a fielder away from gully and D'Oliveira edges the next one through that exact gap and away for four.

Ollie Robinson will have a go with the second new ball in hand but not before Ben Foakes has faffed around a few minutes and changed his bat grip.

Dan Lawrence will face the new cherry on 95.

Brett D'Oliveira dabs Shane Snater down past the slips for four as Worcestershire's total passes 100.

Noah Thain will continue at the other end and there's another glorious cover drive from Kashif Ali which brings him a ninth boundary.

He is 48 not out and D'Oliveira has 13.

Relief for Worcestershire.

Noah Thain flattens Kashif Ali's leg stump - but it's a no-ball.

No-one for the bowler to blame there except himself.

To rub salt in the wound, Thain overpitches with the extra delivery at the end of the over and Ali cover drives for four.

That's a great stroke by Kashif Ali, who drives Shane Snater for four and briefly holds the pose in the follow through. He is 36 not out and Brett D'Oliveira has four.

Derbyshire have lost a wicket against Northants with David Lloyd chasing a wide ball from Dom Leech and carving a catch to Justin Broad. They are 44-1, 149 behind.

Gloucestershire are 106-2 in the 28th over of their second innings against Kent, with Ollie Price and Miles Hammond together, 185 in front.

A good ball from Liam Dawson in his second over goes straight on and deceives Tom Lammonby but it hits the edge of the bat, rolls down the slope, and goes for four unconvincing runs.

We have had a light meter reading after a few clouds gather over The Utilita Bowl but I'm happy to report that we play on for now.

The lights are on, it's been a cloudy grey old day but we're playing cricket that's the main thing and Surrey are making fairly rapid progress here.

Kashif Ali is just beginning to settle dare we say but I would just emphasise what we've been saying throughout.

When you think someone is in, they go and get out.

At the start of Yorkshire's second innings, Adam Lyth needed another 14 runs to reach 15,000 in First Class cricket and he got there with a four in the eighth over.

He and Finlay Bean have made a steady start in the afternoon sunshine of Chester-le-Street, but there's still a lot of work to do for Yorkshire to get back into this game.

Having said that, things were looking bleak this morning when Alex Lees and Emilio Gay put together a record second-wicket stand. But the new ball seemed to change things, with seven wickets falling in 23 overs after its introduction.

Certainly Durham's first innings lead of 120 runs was not as big as many would have expected in the first hour of the day.

A lovely cover drive from Warwickshire's Rob Yates goes for four - the only runs that come from the tenth over.

With no man back, Yates just stood back in his crease and admired his good work.
