Ian Bell's fourth Clydesdale Bank 40 half-century of the season maintained Warwickshire's 100% record with a convincing six-wicket victory over Kent at Edgbaston.

The England batsman contributed a stylish 55 from 71 balls before the Group C leaders - unbeaten in 40-over cricket since August 2008 - wrapped up their fifth straight win in the competition.

The margin would have been greater but for a substantial Kent recovery after 6ft 8in pace bowler Boyd Rankin had taken three wickets in five balls in their collapse to 73 for seven after 19 overs.

Skipper Robert Key survived to reach 87 from 98 deliveries and eventually found substantial support when Rob Ferley made 52, his highest score in all forms of county cricket with Kent and Nottinghamshire.

Their partnership of 94 in 17 overs lifted the Spitfires to a more respectable 192 for nine - but this was nowhere near enough to stretch Warwickshire.

Stephen Moore returned to haunt his former county by hitting an undefeated century in Lancashire Lightning's crushing nine-wicket win over Worcestershire Royals in the match at New Road.

The 29-year-old made 105 not out and put on an unbeaten 191 in 31 overs with Paul Horton, who made an undefeated 78.

Their combined efforts enabled Lancashire to easily reach their 209-run victory target with 5.3 overs to spare.

It was their second Group A win of the season which leaves Worcestershire firmly anchored at the foot of the table following four successive defeats.

Half-centuries by captain Keith Parsons and Josh Knappett set up a famous 58-run victory for the Unicorns over Glamorgan at Dene Park in Bournemouth.

It was the part-timers' first victory in the competition at their fourth attempt as a good all-round effort sent the Welsh county to an embarrassing defeat.

The county side were bowled out for just 173 with five overs remaining in reply to the Unicorns' 231 for eight, which came after Glamorgan captain Jamie Dalrymple put them in to bat.

It leaves Glamorgan, who rested seamers James Harris and David Harrison, with just one win in the competition.

Samit Patel's second limited-overs hundred of his career propelled Nottinghamshire Outlaws to a 12-run victory over winless Hampshire Royals.

Former England one-day all-rounder Patel, 25, started slowly but accelerated in the later stages of the Nottinghamshire innings to finish unbeaten on 108, as the hosts posted a competitive total of 265 for eight, Alex Hales making 46.

Hampshire got off to a flying start but fell behind the required run-rate in the middle overs and despite a battling innings from Sean Ervine, who hit 96 from 88 balls, were unable to recover.

Scotland produced a stunning performance to send Leicestershire Foxes crashing to a four-wicket defeat in a nail-biting finish to their clash at Grace Road.

Chasing a victory target of 218 the Saltires reached it with two balls to spare, helped by half-centuries from George Bailey and Richie Berrington.

But it was Neil McCallum who clinched the victory for the Saltires in their opening game of the campaign, hitting 27 off 19 balls with two boundaries plus a massive six off Matthew Hoggard's final ball of the 39th over.

A fine innings by former England batsman Owais Shah counted for nothing when rain arrived at Lord's to wash out Middlesex Panthers' 40 clash with the Netherlands.

The elegant right-hander reached an unbeaten 74 from 89 balls with six fours and a brace of sixes when persistent rain arrived for a second

time with the Middlesex score on 185 for four after 32.3 overs.
