It's going to be a late finish at Chester-le-Street as the players drift back on to the field.

We have lost no overs to the delay and still have 32 overs left in the day.

Ben Stokes is straight back into the action after his pre-break frustrations.

His line looks much improved and keeps Kashif Ali quiet - no mean feat. Maiden.

Jamie Porter pitches a bit too full and Jamie Smith is forward to clip the ball on the front foot through mid wicket for four.

Smith is purring into top gear and the next ball is lifted imperiously over square leg for six.

He's on 74.

It's century number four of the season for Keaton Jennings and the Lancashire captain again leading from the front for his side

He likes sunny Southport, he has a ton here again.

Good news at Chester-le-Street where play is rescheduled to start at 17:10 BST after our brief delay for bad light and rain.

Not great for batters Kashif Ali and Ben Jones who were rattling along nicely before the break and now have to reset.

Warwickshire are on the charge here, in marked contrast to the first hour of play when they lost four wickets.

Michael Burgess is once again down the track to spinner Jack Leach, lofting the ball over long on for six.

He goes the other way two balls later with a lofted drive over long off for four.

11 runs off that over in total and for Somerset, the new ball can't come soon enough.

It will be available in three overs.

Surrey reach 150 four down in the 46th over and also a fifth-wicket 50 partnership via a Sai Sudharsan back foot nudge to leg off the bowling of Paul Walter.

The stand comes in 76 balls.

It's becoming a really good battle between Michael Burgess and Jack Leach.

Somerset call upon the occasional left arm seam bowling of Tom Lammonby, who starts his spell with a maiden.

Michael Burgess misses with an attempted sweep to a ball outside off but then spoils an otherwise tidy Jack Leach over with six runs swiped over long on charging forward.

A lovely way to reach three figures for Keaton Jennings as he strokes Dillon Pennington through the offside for four.

It is a fourth century of the season and it has come off 179 deliveries with 16 fours and a six.

The England ship may have sailed now, but Jennings is an excellent Championship batter.

And a worry for Notts, Jennings' career-best 318 came at Southport in July 2022 against Somerset.

Hampshire wicketkeeper Ben Brown tucks away a single off Nathan Gilchrist and that helps him to reach a nice half-century.

It is the third time he has gone past that mark this season.

The game has moved on since tea in a way.

30 runs already in five overs and a wicket.

So it's lively old stuff.

Sai Sudharsan plays across the line to Shane Snater but the leading edge drops the ball safely into the off side.

Change of bowling as Jamie Porter returns from the Vauxhall End.

The second ball catches Jamie Smith on the crease, playing and missing with a loose defensive shot.

Maiden over. Testing times for Surrey.

A lovely drive straight down the ground from Keaton Jennings off Dane Paterson gets him four more runs as he moves within one of his century and bring up his side's 200.

But Paterson holds him up with three dots to end the over.

The picture at the top continues to swing the other way as leaders Sussex fight back in Northampton and Middlesex totter at Grace Road.

Ollie Robinson has picked up two wickets and Fynn Hudson-Prentice struck to dismiss Northants top scorer Privthi Shaw for 31 as Sussex reduce the hosts to 88-7, still 55 runs adrift.

At Leicester, Ben Green has followed Ben Mike's early wickets with three of his own to put Middlesex in trouble at 50-5.

Glamorgan have lost their top three as they slip to 66-3, 113 runs behind Gloucestershire's first innings total.

And at Queen's Park, Yorkshire have moved to 146-3, already 70 runs ahead of Derbyshire, with James Wharton unbeaten on 37.

Things are moving quickly in the second tier!

James Vince swivels on to the back foot and pulls Charlie Stobo down to deep square for a single.

He is now into the nineties like Keaton Jennings.

Chris Woakes picks up four runs with a lovely back foot drive through point off Kasey Aldridge.

Just three runs off Jack Leach at the other end as Somerset try to hustle through the last few overs before the second new ball is due.

Seven overs to bowl before that point.

Jamie Smith gets away with one in the 42nd over of the innings.

Shane Snater induces a big drive and the ball runs away wide of slip and past gully for four.

But his next scoring shot is a far more convincing back foot slap through cover point for four more.

Eathan Bosch is into his 13th over of the day and Sai Sudharsan defends down the ground.

Chris Woakes gets a bumper from Kasey Aldridge and the ball runs away to fine leg via the glove for four runs.

But they all count.

The Warwickshire 250 comes in the next over via a back foot cut through backward point for one by Michael Burgess off Jack Leach.

That's a first batting bonus point.

George Balderson has offered great support to Keaton Jennings and he shows why.

He skips down to Liam Patterson-White and hits a lovely lofted shot straight down the ground for six.

Mid-off stays up and Balderson launches the next ball straight down the ground with an even bigger shot for another maximum.

The Southport crowd love it!
