Tribe c Simpson b Unadkat 6 (Sussex v Glamorgan 11-2)
Not the greatest of shots by Asa Tribe who flashes at one outside off stump from Jaydev Unadkat and is caught behind by John Simpson.
"He didn't need to play at that," is the shared opinion of BBC radio commentators Adrian Harms and Nick Webb.
Yorkshire 12-0 v Warwickshire
Yorkshire managed just six runs in the first five overs after being put into bat at Scarborough.
Will Luxton does get things going a bit in the sixth over with a two and a four off successive balls from Ethan Bamber.
Nottinghamshire v Somerset 2-0
Brett Hutton opens from the other end for Notts, so we will have to wait a little longer to see Pakistan international Mohammad Ali bowl on his County Championship debut for the defending champions.
A tidy over from Hutton and just a couple off it for Jordan Hermann, tickling the final ball down to fine leg for two.
Northants 19-1 v Glos
It's an all-Kiwi attack for Gloucestershire at the start of this game, with Will Williams and Kristian Clarke both getting the ball to move around in helpful overhead conditions.
Williams has been tidy so far, sending down 11 dot balls - the exception being thumped over extra cover for four by Calvin Harrison.
Harrison has nine to his name, with home captain Luke Procter yet to get off the mark.
Nottinghamshire v Somerset 1-0
Fergus O'Neill ends the first over with a length delivery outside off and Josh Thomas tucks his bat in to let it pass through to Joe Clarke behind the stumps for Notts.
Somerset survive the first six balls at a very gloomy Trent Bridge.
Geddes c Libby b Taylor 5 (Middlesex 13-1 v Worcestershire)
Jake Libby takes an excellent low catch at third slip and Ben Geddes is gone for 5 with Tom Taylor taking the wicket.
Worcestershire will be relieved as some wayward bowling had seen them concede early boundaries.
Durham 6-0 v Derbys
As you might expect, there aren't many freebies being handed out at the Riverside.
In-form Ben Aitchison's first couple of overs with the new ball have yielded just three runs and Mo Abbas is typically right on the money at the other end.
Nottinghamshire v Somerset 1-0
Slightly delayed start, on, off and now back on again at Trent Bridge.
The players are coming back out after a brief rain shower halted proceedings.
Fergus O'Neill has one ball remaining in the opening over and it's Josh Thomas who will face it.
Leics v Essex (start delayed)
There's been some mopping up going on at Grace Road after overnight rain and showers this morning and the umpires have had a look at the pitch, but decided it's not yet playable.
They'll return for a second inspection at 11:30 BST - so let's hope they'll be in a position to give the green light then.

Wow, the picture at 11.05... are you sure that's not the Grace Road outfield? Even my military medium would stand a chance on that... if I could pitch it!
Mark, Herne Bay
That photo of the pitch at Grace Road is hilarious. I was planning to go and watch tomorrow but fear all 40 wickets might fall today!
Tad, Leicester
Just to remind you what Mark and Tad are referring to, this is the track at Grace Road for Leicestershire's match with Essex, where the start has been delayed because of adverse weather conditions...

Nottinghamshire v Somerset 1-0
Well, that was short-lived. The umpires are taking the players off after just five balls from Fergus O'Neill.
Yorkshire 2-0 v Warwickshire
There was a minutes silence before play started at Scarborough and the players are wearing black armbands in memory of former Warwickshire wicket keeper Keith Piper.
A key player during the Bears multi trophy winning team of the mid 90s Piper died at the age of 56.
Nottinghamshire v Somerset 1-0
Image source, ShutterstockAustralian bowler Fergus O'Neill gets play under way for Nottinghamshire and South African opening bat Jordan Hermann nudges into the legside for a single to get off the mark with the first ball of the game.
O'Neill then finds the edge of Josh Thomas' bat three balls in a row but to no avail.
The first and third don't carry to second slip, while the second loops up to safety.
Middlesex 4-0 v Worcestershire
Impressive start from former England batter Sam Robson as he flicks the first ball of the match, bowled by Tom Taylor, through the leg-side for four.
It's sunny at New Road with the cathedral looking imperious across the river from the ground.
ul Hassan c Simpson b Hunt 5 (Sussex v Glam 5-1)
Having uppercut Jaydev Unadkat over the slips for four in the first over, Zain ul Hassan is surprised by some extra bounce for Sean Hunt as he slashes outside off stump again and edges through to the keeper.
What a start for Hunt - a wicket with his opening delivery in his first red-ball appearance of the season.
Vasconcelos b Clarke 2 (Northants 8-1 v Glos)
That's more what Gloucestershire had in mind when they signed Kristian Clarke!
The final ball of Clarke's opening over swings back late and rips out the middle stump and Ricardo Vasconcelos is on his way.
Calvin Harrison makes his way out to the middle to join Luke Procter.

Nottinghamshire v Somerset
We've got an ever so slight delay to the start of play at Trent Bridge, but nothing major we're told.
It's gloomy overhead but it's not raining at the moment. The umpires have wondered out and given the two sets of players the thumbs up to get going.
Probably a perfect time to tell you that Pakistan international pace bowler Mohammad Ali is making his County Championship debut for Nottinghamshire today.
We may see the 33-year-old in red-ball action for the first time in English cricket very soon.
Northants 4-0 v Glos
New Zealand seamer Kristian Clarke, making his Gloucestershire debut, has the ball in hand straight away - and it's an inauspicious start as his first delivery sails away from Ricardo Vasconcelos and to the rope for four byes.
Vasconcelos is opening up with Northamptonshire skipper Luke Procter and will also keep wicket, with Lewis McManus nursing a toe injury.
