Division One

Sussex are closing in on a crushing victory at Horsham, after piling on the runs in the first innings and then reducing Durham in their second innings to 108 for 6. Durham now trail by a significant 200, with four wickets in hand. Four wickets apiece for Liam Plunkett and Paul Wiseman were scant consolation as Sussex, led by Chris Adams' 193, racked up 517. Sussex now have two more days to close out the match, but they will be confident of doing so on the third.

Anthony McGrath's 24th first-class century helped Yorkshire to a solid position against Warwickshire at Edgbaston, after losing the first day to rain. McGrath was unbeaten on 142 at stumps, and he was well supported by Younis Khan's 49 - together they put on 87 for the third wicket - and particularly so by Jacques Rudolph. The pair added 177 for the fourth wicket.

Division Two

Weighty contributions from Somerset's top order, including Marcus Trescothick's 146, consolidated a promising position at Taunton. Neil Edwards missed out on a fourth first-class hundred, when he fell for 96, while Justin Langer added 83 as Somerset battered their way past Northamptonshire's 221, to take a first-innings lead of 238. When Northants batted again, they lost Chris Rogers and Stephen Peters almost immediately, courtesy of the inevitable Andrew Caddick and Charl Willoughby, but Usman Afzaal (46) and David Sales (12*) began to repair some of the damage. Nevertheless, Somerset are very much in the box seat.

David Hussey's century gave Nottinghamshire a steady platform against Gloucestershire after play finally got underway at Trent Bridge following a first-day washout. Notts eased to 259 for 4, with Hussey unbeaten on 114. The early loss of Stephen Fleming for 1 did not hamper the home side, Jason Gallian making 45 and then Mark Wagh easing to 74.
