The game of the day was at Headingley where Yorkshire held their nerve for a thrilling one-run win over Leicestershire. A century for Jacques Rudolph boosted the home side to an impressive 303 for 4, only for Dillon du Preez to respond with a ton of his own, this one unbeaten, but in an ultimately losing cause as they ended up on 302 for 7. du Preez needed to hit a six off the final ball, but could only manage a four. Rudolph's 120 came from 97 balls, while du Preez's 107 came from a mere 65 as he set about lifting his side from true danger at 198 for 6. He nearly pulled off the heist thanks to a seventh-wicket stand of 94 with Claude Henderson, who made 30, but Darren Gough bowled Henderson and then the visitors couldn't quite scrape home.
Mark Ramprakash capped a good weekend with a fifty as Surrey beat Derbyshireby 13 runs at Chesterfield. Scott Newman also made a half-century before he fell to former Surrey team-mate Nayan Doshi. Another ex-Surrey man, Rikki Clarke, posed a few problems for his old club, putting on 95 with Chris Rogers, but they both fell in quick succession and Derbyshire were from then on playing catch-up. Jade Dernbach ended with 5 for 31 and Usman Afzaal also played his part with 4 for 49.
Azhar Mahmood proved Kent's star turn in their 59-run Duckworth-Lewis win against Glamorgan at Canterbury. He top-scored with 68 to lift them to 202 for 9 and then he took 3 for 14 from six overs to prevent Glamorgan getting a hold in their innings. Chasing 191 from 30.2 overs, they pulled up well short on 131 for 9, Ben Wright the sole batting light with a fifty.
Essex easily sank Northamptonshire at Garon Park after bowling them out for 61 and then cantering to their 61-run target from 37 overs, requiring only 14.5 overs to do so. The pitch had aided bowlers in the Championship match last week and continued to do so with the white ball. There were three wickets each for Graham Napier, David Masters and Chris Wright, while the opener Jason Gallian remained unbeaten on 20 as a simple chase was completed with ease.
Nottinghamshire's 208 for 8 proved enough to pull off a nine-run win by the D-L method when Gloucestershire responded with 92 for 4 from a revised 19 overs at Cheltenham. The visitors' innings was built around Samit Patel's 65, while Chris Read gave them a late boost with 33 after they had slipped to 166 for 6. Mark Ealham's 3 for 10 from four overs then put the skids on Gloucestershire and earned the win, keeping Nottinghamshire top of the table.
Lancashire reached 210 for 8 from a rain-affected 39 overs and Hampshire had reached 14 without loss from five overs when the match was washed out at Southampton. Francois du Plessis and Steven Croft both brought up their fifties, sharing a rescuing stand of 118 for the fifth wicket, while Billy Taylor took four wickets.
There was no result either between Sussex and Worcestershire at Horsham. Worcestershire reached 244 for 9 from their full complement of overs and Sussex had replied with 52 for 2 from 9.3 overs when the rains came. The in-form Vikram Solanki's half-century, then, came to nought, as did Daryl Mitchell's while Luke Wright claimed four wickets the day before England's one-day squad is named.
