Rain puts Sussex joint top
Sussex moved level on points with Warwickshire at the top of Group C in the Clydesdale Bank 40 as their clash with Derbyshire at Horsham was rained off.
The hosts had reached 111 for five after 24 overs when the drizzle became too strong, and umpires Peter Hartley and Peter Willey later abandoned the match.
The result leaves the visitors second from bottom in the group and effectively ends their hopes of qualifying for the knockout stages.
Tim Groenewald took 3-30 from eight overs to reduce Sussex to 58 for four after Derbyshire elected to field.
Joe Gatting and Michael Yardy repaired some of the damage with a stand of 44 for the fifth wicket before Gatting was out for a top score of 34.
Matt Turner made the initial breakthrough in only the fourth over when Ed Joyce misjudged a drive and saw his off stump cartwheel out of the ground.
England all-rounder Luke Wright cracked three quick boundaries before perishing, going for a fourth, when he uppercut a delivery from Groenewald straight to David Wainwright at third man.
Chris Nash followed two balls later when a concerted lbw appeal from Groenewald was finally greeted with a raised finger to the disgust of the batsman.
Scott Styris looked rusty on his Sussex debut, having not seen any action in the recent Indian Premier League, and was next to go.
The New Zealand all-rounder grew frustrated and pulled a short ball from Groenewald down the throat of Alex Hughes at deep midwicket.
Gatting mounted a fightback by hitting Rana Naved-ul-Hasan - on his Derbyshire debut - for six over long-on and Hughes for another maximum.
His innings finally came to an end when he drove Wainwright firmly to short extra-cover where Wayne Madsen took a juggling catch at the third attempt.
Skipper Yardy had moved on to 22 and Ben Brown three when the rain - which had been falling all game - became heavier and the players were taken off.
After a further 90 minutes of solid rain the umpires decided to abandon the match.
