Paul Collingwood made light of his England disappointment by smacking six sixes in an unbeaten 78, as he and Shivnarine Chanderpaul carried Durham to a thumping seven-wicket victory against Middlesex at Uxbridge. The pair produced an unbroken stand of 132 for the fourth wicket as Durham sailed past their target of 201 with 22 balls to spare. Chanderpaul made 58 from 61 balls with five fours and a solitary maximum, to help his side recover from a relative wobble at 70 for 3. Earlier Owais Shah was the mainstay of Middlesex's innings with 73 from 58 balls, but he was unable to find any worthy partners, thanks in no small part to the hostility of Steve Harmison. He finished with 4 for 31 in eight overs.

Matt Prior blasted a brilliant 137 from 123 balls, as Sussex chased down an imposing 243 to win with two balls to spare against Somerset at Arundel. Prior belted 12 fours and three sixes in his innings, and dominated stands of 99 for the second wicket with Luke Wright (40 from 46) and 75 for the fourth with Chris Adams (36 from 36). Though he was bowled by Alfonso Thomas with four runs still needed, Sussex's job had already been done. His efforts overshadowed another fine innings from Marcus Trescothick, who made 91 from 94 balls, and was aided in his target-setting by Zander de Bruyn, who made 70 from 87.

Adam Voges made a run-a-ball 85 to put Nottinghamshire beyond the reach of a subdued Hampshire at Trent Bridge, as they eased to a comfortable 31-run victory. Not even the redoubtable six-hitting talents of Hampshire's captain, Dimitri Mascarenhas, could rescue his side. He smacked four maximums in a 35-ball half-century to ease the margin of defeat, but apart from Michael Lumb, with 63 from 66 balls at the top of the order, no-one else in the line-up passed 30. Voges, on the other hand, was joined by Bilal Shafayat who made 45 from 56 balls in a 93-run stand for the fifth wicket. Chris Tremlett, overlooked by England this week, responded with three wickets, but Nottinghamshire's total of 231 for 9 always looked sufficient, especially when John Crawley fell third-ball for a duck.

A brilliant 99 from just 66 balls from Ryan ten Doeschate nearly took Essex to a remarkable win over Leicestershire at Grace Road, the match ending in a thrilling tie. Chasing 256, Essex looked set for defeat with 16 needed from the final over, but Dillon du Preez was hit for a huge six followed by another four with three needed from the final ball. He could only grab two from the last delivery, levelling the scores, but it represented a wonderful comeback for Essex who had slipped to 99 for 5 at the halfway point. Leicestershire's innings was set-up by fifties from Boeta Dippenaar, Paul Nixon and Matthew Boyce, who cracked a career-best 59 from 65.

Dan Birch paced Derbyshire's reply to perfection with eight fours and four sixes in a 59-ball 76, as Northamptonshire's stiff target of 223 was overhauled with disdainful ease at Wantage Road. Birch added 111 for the third wicket with Wavell Hinds, who made 45 from 36 balls, and by the time he was run out with 69 runs still needed, the back of the run-chase had been broken. Greg Smith wrapped up the contest with 26 balls to spare, to overshadow a valiant rescue act from Northants' David Sales. He made 96 not out from 109 balls to rescue his team from the depths of 51 for 5, with his captain, Nicky Boje, chipping in with a vital 59 from 40 balls. Ian Hunter was the pick of Derbyshire's attack with 3 for 18 in eight overs.

Jonathan Trott batted from first ball to last to record a brilliant 91 not out from 102 balls, but Warwickshire still fell 22 runs short of their target of 229 against Kent at Edgbaston. Instead the honours went to Kent's captain, Rob Key, whose 80 from 83 balls proved the decisive innings of the day. After losing Joe Denly for a duck, Key added 83 for the second wicket with the form batsman of the moment, Martin van Jaarsveld, then found another doughty ally in Matt Walker, who made a run-a-ball 43. Trott, by contrast found no-one to stay with him - Darren Maddy made 28 and Tim Groenewald a brisk 33, but no-one else in the Warwickshire line-up passed 11.

Yorkshire's bowlers held their nerve against the big-hitting of Jade Dernbach to record an 11-run win over Surrey at Guildford. Yorkshire's 230 for 7 was set up by Andrew Gale's 40-ball 44 and a useful 33 from 34 balls by Adil Rashid, with contributions from all but two of their batsmen. Chasing 231, Surrey slipped to 25 for 3 before Chris Schofield smacked 58 from 44 balls to give them hope. But he fell to Darren Gough (2 for 62), and though Jonathan Batty (24 from 20) and Dernbach (19 from 7) took them close, the failure of Surrey's top-order cost them dear.
