Geraint Jones struck his second Championship hundred of the season, joining Martin van Jaarsveld and Yasir Arafat who also struck centuries, as Kent declared on a sizeable 550 for 9 on the second day at at Canterbury. van Jaarsveld received good support from Neil Dexter, with whom he put on 172 for the fifth wicket, before Jones and Arafat took the initiative from Warwickshire with confident tons. Kent's bowlers then made good their batsmen's grind with two quick wickets; Darren Maddy falling for 23 and James Tredwell removing Ian Westwood, leaving Warwickshire stumbling on 43 for 2.

There were only two overs possible at Headingley between Surrey and Yorkshire, the hosts moving to 212 for 8.

Durham's second day against Hampshire at Chester-le-Street was washed out.

Cameron White took 4 for 28 to help Somerset dismiss Essex for 282 on the second day at Taunton. Essex lost Grant Flower, shortly followed by James Foster, but Mark Pettini, their mainstay yesterday, dropped anchor to defy the Somerset bowlers. However when White bowled him for 73 the Essex lower-middle order offered little of substance, especially against White's turn. Essex hit back - Tony Palladino trapped Neil Edwards leg-before - before rain curtailed the day's play with Somerset on 28 for 1.

Derbyshire's second day against Glamorgan at Derby was also washed out.

Leicestershire's match against Middlesex at Grace Road still has yet to get underway due to rain.
