Nottinghamshire remained unbeaten in the North Group as a record Lancashire opening stand between Stephen Moore and Tom Smith proved in vain in a rain-affected eight-wicket Friends Life t20 win.
Moore (80) and Smith (56) smashed 119 from the first 14 overs before acting skipper Steven Croft (31 not out) added late impetus to carry Lancashire to an imposing 178 for four.
A lengthy rain delay with Nottinghamshire seven for none after just one over of their reply left the hosts chasing 42 runs from four overs to reach a revised victory target of 49.
And once Yasir Arafat's over went for 18 - Riki Wessels (21 not out) striking three fours in four deliveries - the Outlaws were always going to get home, especially after Michael Lumb (22) had rattled the scoreboard along.
Sussex booked their place in the quarter-finals of the Friends Life t20 and ended Surrey's hopes in the process following an emphatic six-wicket South Group win at The Oval.
Surrey struggled to 106 for six before rain brought their innings to a premature end after 16.2 overs with Zander de Bruyn top scoring on 30 not out and Mike Yardy taking two for 15.
Sussex made light work of reaching a revised target of 109 off 15 overs with Luke Wright (32), Matt Prior (25) and Chris Nash (22) steering them home with 20 balls to spare despite the efforts of Gareth Batty (three for 11).
Glamorgan's clash with Worcestershire Royals was abandoned without a ball bowled at the Swalec Stadium because of rain.
The Royals clash is the fourth of the Welsh side's eight games to end up as a no result. It means their hopes of reaching the quarter-finals are now over.
But the Royals' point from the game keeps up their hopes of reaching the last eight with three of their games remaining in the group.
Rain looked like it had cleared up in Cardiff and the umpires - Steve Garratt and Jeff Evans - had been getting ready for a seven-over contest starting at 8.15pm.
But when more heavy rain arrived at the ground they had no other option but to call the match off.
