Somerset 73-4 v Surrey
Image source, Rex FeaturesJamie (left) and Craig Overton
Jamie Overton is thrown the ball for the first time this morning to bowl against his old county.
With brother Craig in the Somerset team, which brother will come out on top?
In the recent T20 Blast semi-final, Jamie was caught in the deep by Craig as Somerset won by 24 runs.
Hampshire 72-5 v Essex
Hampshire are in real trouble now.
Jamie Porter is back for his second spell, switching ends, and immediately collects his third wicket as Nick Gubbins drives and is caught behind off a thick edge.
Felix Organ emerges to join Liam Dawson and they'll be desperate to at least make sure they get through until lunch.
Warwickshire 60-9 v Middlesex
Oliver Hannon-Dalby now into double figures with a guided four through first slip.
Lancashire v Northamptonshire 60-3
Northants captain Luke Procter is struck a painful blow on the arm as a delivery from Will Williams gets up more than he anticipated.
The physio comes on to treat him because that looks a sore one.
Somerset 66-4 v Surrey
We have an intriguing battle here with Will Jacks bowling to Tom Kohler-Cadmore.
TKC has hit one six off the spinner but any aggression will have to be controlled with Somerset in a spot of bother.
Hampshire 68-4 v Essex
That's a great catch by Simon Harmer!
He flings himself to his left at second slip and pouches the edge from Ben Brown one-handed, just above the turf.
Deserved wicket for Sam Cook, who's bowled extremely consistently this morning and Essex are on top.
Lancashire v Northamptonshire 59-3
The spinner strikes!
Jack Morley has a wicket in his second over, but goodness me, Sam Whiteman!
Being positive is one thing, but Whiteman launches a pre-meditated charge down the crease, misses the ball and is stumped by miles.
That is poor, poor cricket.
Warwickshire 50-9 v Middlesex
Ironic cheers in Brum as Oliver Hannon-Dalby brings up the 50, with a miscued steer for two down to third man.
200 more to go for a first batting point.
Notts 76-1 v Kent
Image source, Getty ImagesBen Slater completes his third half-century of the campaign, drilling Matt Quinn to the cover fence and then adding three with a straight drive to reach the landmark from 70 balls.
Good knock from the Notts left-hander, who shared that opening stand of 65 with Haseeb Hameed.
Somerset 57-4 v Surrey
The fall of George Bartlett has seen James Rew walk to the crease.
Rew has been the star batter of 2023 with 974 runs, including five centuries.
The wicketkeeper-batter is still only 19, but what a prospect he looks.
Warwickshire 48-9 v Middlesex
Ryan Higgins takes just five balls to get in on the act.
Henry Brookes is the latest to offer catching practice - and Tom Helm takes it safely in the cordon.
Also, at nine down now, this technically delays lunch by half an hour!!!
Warwickshire 48-8 v Middlesex
Both the new-ball attack have now been seen off by Warwickshire's ninth-wicket pair.
After seven overs of Toby Roand-Jones, Tom Helm came on - and now Ryan Higgins has ended Ethan Bamber's nine-over stint.
Lancashire v Northamptonshire 53-2
With two spinners in the side, Keaton Jennings has little option but to turn to them.
Jack Morley is the first to bowl and a short loosener is cracked to the boundary by Sam Whiteman.
That brings up the 50 in the 20th over of the innings.
Hampshire 59-3 v Essex
Essex have come back well here since the blow of losing Shane Snater to injury.
Sam Cook is back on, bowling a tight line to stem the flow of runs, and left-armer Paul Walter has now picked up the visitors' third wicket of the morning.
Walter slants the ball across Hampshire captain James Vince, who has a nibble and Adam Rossington snaps it up behind the stumps.
Notts 65-1 v Kent
Former Notts all-rounder Joey Evison is back at Trent Bridge with Kent and bowling his first over of the match.
Evison's first delivery is a full toss that Haseeb Hameed clouts for four - but he responds three balls later by trapping the opener leg before as he shuffles across.
Will Young comes to the crease to join Ben Slater.
Somerset 57-4 v Surrey
This is turning into a dream morning for Tom Lawes and Surrey.
Lawes puts the ball in the right spot again, tempting the drive and George Bartlett's edge flies to third slip.
Bartlett never looked comfortable and he has been put out of his misery.
Notts 47-0 v Kent
Ben Slater has certainly stepped it up a gear after those first nine meagre overs, when Nottinghamshire managed just nine runs.
The left-hander has advanced to 36 not out, although he just survived an appeal for caught behind off an inside edge against Matt Quinn.
Haseeb Hameed is alongside Slater, with nine to his name.
Somerset 40-3 v Surrey
After seeing Somerset win the toss and deciding to bat, Surrey must be thrilled with this position.
They have two batters on nought and a string of close catchers.
Warwickshire 43-8 v Middlesex
Image source, Rex FeaturesFive wickets for Ethan Bamber, for the third time in his career - and four of them have have hit the stumps!
Ed Barnard goes too as the ball moves away and nips the outside of the off stump.
Oliver Hannon-Dalby is the new man in, ahead of Mir Hamza in the order. Not sure what that says about either.
But if either of them are still there at lunchtime, then the Bears will have done well.
The Bears’ lowest total against Middlesex is 55 at Lord's in 1955, when they were bowled out inside 26 overs by Alan Moss and JJ Warr. it would actually be a bit of a comparative triumph now getting past that!
Somerset 40-3 v Surrey
The leaders are in big business here!
Sean Dickson had hit the previous two balls for four, but when Tom Lawes produces a bit more bounce, it takes the edge of Dickson's bat.
It flies to second slip where Tom Latham takes it expertly over his head as that was travelling.
