Sussex booked their place in the quarter-finals of the Friends Life t20 after claiming a convincing six-wicket win over Surrey at the Kia Oval.
Surrey, who own hopes of a spot in the last eight were ended with the defeat, could only struggle to 106-6 before rain brought their innings to a premature end after 16.2 overs.
Sussex were given a revised target of 109 from 15 overs, a score they chased down with 20 balls to spare despite Gareth Batty's figures of 3-11.
The hosts were put in to bat and although they made a positive start, a flurry of wickets put the brakes on their hopes of setting a big target.
Steven Davies had shown some promise at the top of the innings but was dismissed for 21 when he carved a wide ball from Chris Liddle straight to Murray Goodwin.
The only other Surrey batsmen to make it into double figures were Zander de Bruyn, who made an unbeaten 30, and Rory Burns, who scored 23 before falling one ball prior to the rain intervened.
Michael Yardy finished as the pick of the bowlers with 2-15 while Will Beer got rid of Kevin Pietersen, who followed his duck against Hampshire the previous night by being caught on the boundary for eight.
Chris Nash set the tone for Sussex's reply as he blasted 22 off the first two overs before top-edging a catch to Davies off the bowling of Stuart Meaker.
Matt Prior plundered 25 off just 10 balls, including a big six off Dirk Nannes, only to be caught on the boundary, while Luke Wright made 32 off 21 balls when he offered a return catch to Batty. But the visitors still eased across the line.
