Nottinghamshire 10-0 v Lancashire
An early chance for Lancashire as Ben Slater edges Saqib Mahmood to second slip...
...dropped!
It was a tough chance to be fair. Although England's Mahmood is furious.
And we also have an early wicket in Division Two as Durham's Chris Rushworth pins Glamorgan's David Lloyd leg before.
It's 9-1 at Chester-le-Street.
Elsewhere, Gloucestershire are going steady at Chelmsford. They're 13-0 against Essex after four overs.

Abell c Duke b Fisher 2 (Yorkshire v Somerset 2-1)
Beauty from Matthew Fisher!
The Yorkshire paceman gets one to lift and nip away from Tom Abell and the Somerset captain can only snick it behind.
Nottinghamshire 5-0 v Lancashire
Nottinghamshire are unchanged from the side that beat Somerset last time out.
Batters Ben Slater and Ben Duckett have comfortably blocked out the first couple of overs.
Yorkshire v Somerset 2-0
The two Toms - Abell and Lammonby - are in the middle at Scarborough.
Yorkshire paceman Matthew Fisher has just got through his first over.
Warwickshire v Hampshire (start delayed)

As things stand there is no play at Edgbaston. And no news of when there'll be a likely start.
Well, that news from Edgbaston came out of the blue.
Thankfully we have cricket at the other seven grounds...
Warwickshire v Hampshire
No toss or team news coming out of Edgbaston.
Worryingly, we think this is the reason why...

A quick reminder of the format...
Six teams are still in with a shot of winning the title - Nottinghamshire, Lancashire, Warwickshire, Hampshire, Yorkshire and Somerset.
They're going head to head in a four-game shoot out for the crown and this is their second match.
The other 12 counties have been split into another two divisions and are playing for wins and pride, not silverware.
We'll keep a close eye on the Division One fixtures, and bring you the best from the rest.

Summer is set to make a return and we have four days of stonking domestic cricket to go with it.
Welcome...
