Surrey 323-8 v Notts
Impatience costs Sean Abbott a half-century for Surrey.

Yorkshire 154-0 v Worcestershire
In fact that is it for the day at New Road.
Adam Lyth (77) and Fin Bean (69) return to the pavilion unparted.
Another chance to build on this in the morning. But the weather forecast is not great.
Somerset 196-5 v Hampshire
No!
Madness. The players reach the square, take a look up, look at the umpires, and they all agree to trudge back off again. Not a ball was bowled.
Mohammad Abbas has a face like thunder, you suspect he's been made to rush a biscuit or pour a perfectly good cuppa away in order to dash back out there for the aborted-resumption.
Anyway, as you were. Covers coming back on.

Helm bangs in a short ball and Sanderson scythes the ball away through gully for a single.

Six more hooked behind square!

No idea how, but they're back out in the middle inbetween the sharp summer showers.
We had a seven-ball session after lunch..... will this be any longer?
Durham v Glos 280-6
As expected, the elements have forced an early close in this Durham-Gloucestershire contest.

Somerset 196-5 v Hampshire
It was forecast. In theory there are 19 overs remaining but not sure how many of them we will see.
James Rew (77) and Kasey Aldridge (55) have added 116 in 27 overs together to haul Somerset back into this game.
James Vince is all smiles walking off... probably until someone reminds him of the horror drop of Aldridge on eight.
Surrey 292-6 v Notts
Image source, Rex FeaturesWhat an under-rated cricketer Jordan Clark is.
