Jacques Rudolph's century propelled Yorkshire to a handy 339 for 6 against leaders Somerset at Taunton, although he was nipped out just before the close for 155, one of a trio for Ian Blackwell. Rudolph and Gerard Brophy shared a fourth-wicket stand worth 130 before falling within 15 runs of each other. Somerset welcomed back Andy Caddick after his shoulder injury but he finished with 0 for 70 off 16 overs.

Callum Thorp's 5 for 64 was the highlight of a bowler's day for Durham at Chester-le-Street, his third first-class five-for in 27 matches. The Harmison brothers cleaned up the other five between them, Stephen with two and Ben with 3 for 25. Michael Carberry and Sean Ervine both made fifties to push Hampshire's total to 239 but they should have done much better as their last eight wickets contributed only 80. Durham lost Mark Stoneman in reaching 59 for 2 and could have been in even more trouble had Michael Di Venuto not survived a claim for a catch at slip when he had made 6.

The opening day of Kent's tussle with Sussex was lost to the rain at Canterbury. Having had to shift the FP Trophy quarter-final away from the ground on Wednesday, it was still not fit for play on Friday after steady drizzle throughout the morning. Play was abandoned at 3pm.

Charl Langeveldt and Graham Wagg took four wickets each as Derbyshire bowled out Worcestershire for a lowly 151 at Chesterfield. The visitors, who won the toss, were indebted to No. 10 Steve Magoffin's 33 for lifting them from 101 for 9 to something slightly less paltry. Langeveldt claimed the key wicket of Vikram Solanki, superbly caught at second slip, then Graeme Hick dragged Jonathan Clare into his stumps. Clare could have had another, but spilled a tough return catch off Ben Smith, although wickets were never far away.

Stand-in captain Ian Westwood batted all day to make an unbeaten 139 as Warwickshire reached 278 for 4 against Glamorgan at Cardiff. He and Navdeep Poonia (37) put on 119 for the first wicket and though Michael Powell fell on the same score, Westwood, drop by Robert Croft at first slip off Alex Wharf when on 70, remained resolute.

Fifties from Marcus North and Alex Gidman lifted Gloucestershire from a stumbling 77 for 2 to a sturdier 258 for 4 against Northamptonshire at Northampton, with North still unbeaten on 84, after reaching his fifty off 88 balls following an indifferent run of form. The Kolpak pair of Johan wan der Wath and Andrew Hall did the damage alongside Johann Louw. It needed a team effort to remove Hamish Marshall, who edged to second slip only for David Sales to fumble the chance. However, Hall was alert at first slip to take the rebound.
