Leicestershire fail to thwart Swart
Group A leaders the Netherlands continued their outstanding start in the Clydesdale Bank 40 courtesy of Michael Swart's century against bottom-of-the-table Leicestershire at Grace Road.
Swart struck 102, Tom Cooper 68 and Cameron Borgas 61 not out as the visitors, who have now won five of their seven games in this year's competition, reached 304 for three.
Ramnaresh Sarwan struck an 89-ball 115 in response, only to be run out as the Netherlands eventually emerged victorious by 43 runs.
Ravi Bopara marked his return for Essex with a century that helped seal an eight-wicket triumph against Gloucestershire at Chelmsford - their first win in this year's competition.
Bopara has been missing due to a thigh injury in recent weeks yet - well supported by Tom Westley's 82 - came back in style with 120 not out.
Kane Williamson's 77 had earlier helped Gloucestershire to a total of 224 for five.
Tim Ambrose ensured Warwickshire recovered from a rocky start to overcome Derbyshire and move top of Group C.
The Bears lost three early wickets as Mark Turner impressed, but Ambrose made a defiant 77 not out in a score of 242 for six.
Derbyshire, chasing 243, faltered from the beginning of their reply, with Steffan Piolet's four wickets helping Warwickshire to a 105-run success at Derby.
In Group B, Michael Carberry continued his outstanding one-day form as second-placed Hampshire beat Scotland by six wickets at the Ageas Bowl.
Not content with scores of 60, 76, 103 not out and 54 in List A cricket this season, Carberry added a career-best unbeaten 148 after Hampshire had initially struggled in their chase.
Earlier, Scotland were indebted to Majid Haq's unbeaten 53 as they reached 230 for nine.
Basement club Somerset endured another afternoon of disappointment in being beaten by Nottinghamshire at Trent Bridge.
Last year's finalists have not won in this year's competition and left themselves with an uphill struggle by posting just 205 for eight.
Michael Lumb and Riki Wessels compiled 65 and 55 respectively as Nottinghamshire cruised home.
