Middlesex v Northants 89-3
Image source, Rex FeaturesGone! Justin Broad is stuck on the crease, out of position trying to clip Helm to the leg side.
Absolutely plumb.
Great start to the session for Middlesex - and a captain's innings is needed for new batter Luke Procter.
Durham v Glos 108-2
Hammond is off to a bright start this afternoon as he whips a leg side ball from Potts through ide mid-on for four runs.
Pretorius drops short and Dent pulls to square leg for two. One more pulled to leg off the fourth ball.
Kent 91-7 v Warwickshire
You can take Grant Stewart away from the white ball but you can't take the white ball away from Grant Stewart...
The big Aussie-born Italian international wallops Australian international Glenn Maxwell for a picture-perfect straight six. 10 off the over, following up a wicket-maiden.
Yorkshire 142-0 v Worcestershire
Just 20 balls into the afternoon session - and we're off for rain again.
This looks like a more extended break, following the short 10-minute morning interruption.
Middlesex v Northants 83-2
A tidy spell so far for De Caires, who has conceded only three off his first two overs.
Whiteman tries to pull the last ball of the over to square leg and misses.
Helm continues from the Benham End - and his second ball is driven through extra cover for four runs.
Four more flicked to fine leg - followed by a play and miss off a back foot drive.
Northants trying to go up a gear here.

That's his third Championship 50 of the season. 88 balls and five fours.

A wicket straight after lunch at Hove, with Tom Haines caught at first slip for 86 after pushing forward defensively to Alex Thomson.
Tom Alsop has now joined Tom Clark and Sussex are 150-1 after 30 overs against Derbyshire.
No such luck for Worcestershire, with Finlay Bean (57*) and Adam Lyth (69*) safely negotiating the latest Ben Gibbon over at New Road. Yorkshire are 134-0 after 28.
Kent 78-7 v Warwickshire
Big wicket for Warwickshire. Oliver Hannon-Dalby, recalled to the side, has his third scalp, getting Joey Evison to nick to the diving Michael Burgess to take a fine catch to his right.
Kent are up against it at Canterbury.
Hamid Qadri joins Grant Stewart with Kent still well short of three figures.
Middlesex v Northants 74-2
Almost a second wicket in the over for De Caires, as Whiteman inside edges his first ball just short of short leg - and then half an LBW shout as Whiteman is right back on the stumps trying to defend.
Just going over the top. Not an encouraging start for Northants.
Somerset 74-4 v Hampshire
Only seven balls were possible after lunch at Taunton before the rains returned... looks like an afternoon of dodging sharp showers in the west country.
Lancashire v Essex 12-1
You need to be the sunniest of optimists if you are at Stanley Park in Blackpool at the moment.
It is still raining and we're getting to the point now where we must wonder whether play will be able to resume today.
Just 4.1 overs bowled in the game so far. Tom Westley is eight not out for Essex and Alastair Cook has four.
Middlesex v Northants 71-2
Middlesex removed both openers before lunch, with Emilio Gay falling just before the break to off-spinner Josh de Caires.
Just two balls bowled by him so far, so he'll complete the over, bowling to new Northants batter Sam Whiteman.
Slip and short leg in place.
Surrey 74-4 v Notts
Lyndon James completes the over interrupted by lunch at The Oval and Will Jacks helps finds the boundary from the final delivery via a thick edge past the cordon.

Chris Dent resumes unbeaten on 49 with Miles Hammond.
Matt Potts to bowl to Dent.
Surrey 70-4 v Notts - lunch
Image source, Rex FeaturesThe pro-Ben Foakes lobby continue to act as social media 'boosters' for the Surrey wicketkeeper in the hope that he will be involved in the final two Ashes Tests.
The only gloves Foakes will be wearing this afternoon at The Oval are ones for batting and the Division One leaders need some runs from him after finding themselves in a sticky situation at lunch - and we're not talking treacle tart on the menu.
He was nought not out at the interval, having faced just five balls so far. A big score today will do his team and his England ambitions a power of good.
Glamorgan v Leicestershire - start delayed
The covers are still on at Sophia Gardens, so little prospect of an early start to the game this afternoon.
The umpires had hoped to be out there at 13:10 BST but the weather closed in again and so it's back to idly flicking through mobile messages etc for the players.
Sussex 15-0 v Derbyshire - lunch

Image source, BBC SportA good toss to lose for Sussex who having been put in have raced to 150 without loss this morning.
Tom Haines has led the charge hitting 15 boundaries his fourth half-century of the season, albeit with the benefit of a short boundary on one side
Tom Clark has been happy to play second fiddle, but passed 50 for the second time in 2023 just before lunch
Haines had a life on 64 when the normally reliable Wayne Madsen spilled a chance at first slip, but in reality its been a very poor morning for the visitors.
Somerset 74-4 v Hampshire - lunch

In 2019 he virtually single-handedly denied them the County Championship by taking 17 for 86 in their penultimate game at the Ageas Bowl, and this morning he increased his tally of Somerset wickets by another three to 56.
Abbott also diverted a Sean Dickson drive onto the stumps in his follow through to run out the unfortunate George Bartlett.
For a Somerset side missing several key players with T20 Blast Finals Day in mind, it was not a good morning.

One-way traffic this morning at Hove with Tom Haines and Tom Clark batting through the opening session to lay the foundation for a substantial Sussex score.
Haines has batted superbly for his 86 not out off 95 balls, including 15 boundaries, while Clark hit 11 of his own to reach 54 not out.
Derbyshire have tried six bowlers so far but are still waiting for their first breakthrough.
