Hampshire hit the summit
Hampshire moved to the top of Group B in the Clydesdale Bank 40 after Neil McKenzie produced a brilliant innings in their 107-run win over the Welsh Dragons.
McKenzie’s 88 from 89 balls helped the Royals, who lost the toss, post 226 all out at the SWALEC Stadium.
In reply Chris Wood recorded career-best figures of 5-22 and Danny Briggs took 4-32 as the Dragons were completely outclassed.
The hosts could only make 120 all out with 7.1 overs unused, ending their realistic hopes of reaching the semi-finals.
Hampshire had reached 27 without loss in four overs but were pegged back when Jimmy Adams and Simon Katich fell in quick succession.
James Vince looked certain to go to his 50 but was run out by wicketkeeper Mark Wallace two runs short of the milestone.
The exit of Vince and some disciplined bowling, especially from Jim Allenby, slowed the run rate and Hampshire reached the halfway stage on 102 for three.
That became 108 for four in the next over when Sean Ervine was brilliantly stumped by Wallace, and 109 for five when Allenby trapped Liam Dawson lbw.
Allenby, who finished with 1-21 from eight overs with two maidens, had an assist when Michael Bates was run out in a mix-up with McKenzie attempting a third run.
South African McKenzie reached his half-century from 59 balls and - although Hamza Riazuddin holed out to mid-on - Chris Wood helped take 15 off an over from Glover.
Wood was well caught by Marcus North one-handed at midwicket but Danny Briggs struck Graham Wagg for two sixes in between losing McKenzie, who holed out off the expensive Simon Jones seven balls from the end of the innings.
The Dragons were not helped by being penalised six runs for not bowling their overs in the time allotted.
They were soon on the back foot in their reply when they were reduced to 21 for three in six overs by Wood; Wallace was caught mistiming a pull, Chris Cooke fell to a good catch by Dawson at short midwicket and Gareth Rees was bowled.
Allenby and North did their best to get the hosts back on course but David Griffiths had the latter caught behind attempting to drive.
Briggs then had Allenby caught on the long-on boundary and the batting powerplay was subsequently taken with the Dragons needing 135 off the final 14 overs.
Such a stiff target was always likely to prove impossible and Wagg, Ben Wright and John Glover were bowled by Briggs before Wood returned to clean up Cosker and Jones with consecutive balls.
