Hampshire followed up their success at t20 finals day by booking themselves a Clydesdale Bank 40 final date against Warwickshire with a comprehensive eight-wicket victory over Sussex at Hove.
Openers Michael Carberry (68) and James Vince (58) launched a blistering assault before Simon Katich (47 not out) and Jimmy Adams (44no) completed the job as Hampshire chased down Sussex's total of 219 for eight with 42 balls to spare.
Luke Wright had made a brilliant 122 for Sussex but they collapsed from 195 for three to 199 for eight as Sean Ervine took three for 36 and Danny Briggs two for 32.
Hampshire will now play at Lord's in a fortnight hoping to complete a limited-overs double having lifted the Friends Life t20 trophy at Cardiff last weekend.
Varun Chopra's century proved crucial for Warwickshire Bears as they clinched a second final appearance in three years with a resounding semi-final win by 23 runs over Lancashire Lightning at Old Trafford.
A candidate to be England's new Test opener, Chopra anchored the 2010 winners' score of 250 for six with 110 off 124 balls, including nine fours and a six.
Lancashire then crumbled to 90 for five in reply as they went on to lose for the first time in seven matches at Old Trafford this season, setting up a Lord's final between Warwickshire and Hampshire on September 15.
This was also Lancashire's 11th semi-final defeat in the last 12 in all forms of limited-overs cricket as they were bowled out for 227 with two balls left.
New ball bowler Neil Carter excelled with four for 38, while Paul Horton top-scored for the hosts with 78 off 63 balls.
