Hampshire beat Nottinghamshire by 122 runs to go top of Division One
Lancashire earlier beat Somerset by 10 wickets at Taunton to move into second place
Play abandoned for day at Headingley where Yorkshire need 224 to beat Warwickshire
Division Two: Glam v Gloucs only match to see play
No play possible in all three Division Three fixtures
We only saw action from a few of our fixtures today but boy did they deliver.
This is why we love red-ball cricket. Anything can happen at any moment.
Stay with us for what looks likely to be a much drier one tomorrow. Plenty more twists and terms to come as the penultimate round concludes.

Image source, .So Hampshire and Lancashire sit first and second after their wins today.
But that table will change of course before next week's final round once we know the result between Yorkshire and Warwickshire on Wednesday.
Should Yorkshire get the 174 more runs they need it would put them second and a point behind Hampshire.
A Warwickshire win would put them in second place - half a point ahead of Lancashire and three-and-a-half behind Hampshire.
Mouth-watering stuff.

They would go above Lancashire, who went top earlier on after beating Somerset.
There would be just four points between the two sides who meet in next week's final round at Aigburth.
Exciting stuff.
