Erm...
Leicestershire v Derbyshire - day one abandoned, rain
Richard Rae

A dry period at noon, during which the ground staff managed to remove much of the standing water, raised hopes of at least a few overs play late in the day at the Fischer County Ground.
But the return of the rain 30 minutes later confirmed the inevitable, and umpires Michael Gough and Jeff Evans have duly made the call after the usual outstanding lunch - now generally acknowledged to be the best on the county circuit.
During lunch, umpire Evans let slip he had spent a couple of weeks of his winter in Kenya, during which he visited the Masai Mara reserve. "Saw everything", he vouchsafed, meaning the full panoply of magnificent African wildlife. "Could have seen most of them in Wales, of course, but not quite the same, is it?"
Middlesex 34-2 v Glamorgan
Bowled 'im!
Big Aussie seamer Michael Hogan nips one back in to Sam Robson and the Middlesex opener is bowled through the gate.
England's Dawid Malan is the new man in.
Middlesex 34-1 v Glamorgan
Stevie Eskinazi is into attacking mode straight away for Middlesex with a couple of fours.
I'm afraid to say the weather appears to be closing in again at Lord's - but for now they carry on.
Hampshire 41-0 v Essex
Nick Gledhill
BBC Essex
Hampshire will be pleased with their start in the hour's play possible after an uncontested toss.
Jimmy Adams could be in his final season but has looked in fine form with some confident cover drives. Joe Weatherley is looking to stake his claim for a regular spot at the top of the order and needs to take this opportunity after a good start.
The Essex bowlers have found some movement with opening bowler Sam not the only Cook returning to the Essex side at a ground where he impressed last season.

The rain has now arrived at Hove and they're off.

Breakthrough for Glamorgan!

Stevie Eskinazi joins Sam Robson in the middle.

Phil Salt is really enjoying himself at Hove!
The Sussex opener smashes Matt Taylor for a six and a four to move to his half-century off just 59 balls.
Sussex are flying.
Hampshire 41-0 v Essex
Doh, it's now raining at the Ageas Bowl and off they come.
So frustrating.

It's off at Leicestershire for the day.

Hampshire 41-0 v Essex
Shot!
Jamie Porter strays onto Joe Weatherley's legs and the 21-year-old clips him to the boundary.
This is now an excellent start for Hampshire.
Sussex 66-0 v Gloucestershire
A day for the bowlers? Nonsense.
Phil Salt and Luke Wells continue on their merry way for Sussex - Salt on 38, Wells on 21.
No wickets in any of our three games.
Middlesex 6-0 v Glamorgan
Play has indeed got under way again between Middlesex and Glamorgan.
Max Holden and Sam Robson are at the crease for the hosts.
Hampshire 36-0 v Essex
And a third boundary behind point off Sam Cook's over - this time by Jimmy Adams.
13 off the over.
Hampshire 31-0 v Essex
Too short from Sam Cook.
Joe Weatherley flays the seamer down to the third-man boundary before slashing him through point for another four.
Essex will surely be frustrated they are yet to find the breakthrough.
Leicestershire v Derbyshire - match delayed, rain
Dave Fletcher
BBC Radio Derby Sport
There was no play before lunch after a morning deluge at Leicester with standing water forming on the outfield.
Groundstaff started working to tidy up the covers as an early lunch was taken, but the forecast for the rest of the day is not good.
Hampshire 23-0 v Essex
Australian paceman Peter Siddle comes into the attack for defending champions Essex and starts with a maiden.
It's tough for the batsmen out there, but Joe Weatherley and Jimmy Adams are doing a sterling job.
Middlesex 6-0 v Glamorgan - play to resume at 12:15 BST
I'm hearing reports that the sun is out at Lord's. Surely not?
