Nottinghamshire maintained their unbeaten record in the Friends Life t20 with an eight-wicket Duckworth/Lewis victory over Lancashire at Trent Bridge.
Stephen Moore (80) and Tom Smith (56) smashed an opening stand of 119 for Lancashire as the visitors posted an imposing total of 178-4.
However, a lengthy rain delay then commenced with the Outlaws on 7-0 after just one over of their reply and when play restarted, Nottinghamshire were given a revised target of 49 from five overs.
And once Yasir Arafat's over went for 18 the Lightning were always on the back foot as Riki Wessels (21 not out) and Michael Lumb (22) helped the home side across the line with ease.
The outcome could be considered harsh on Lancashire, who had batted well over the course of their 20 overs after being put in to bat.
After a start delayed by 35 minutes Nottinghamshire, who went top of the North Group with victory, bucked their usual trend of batting first and took to the field under floodlights.
The ball moved around early on for Harry Gurney and Smith was fortunate to escape when on eight when Hales dropped a high ball off the left-armer's bowling.
Smith slog-swept Samit Patel over the ropes and also skied the same bowler up over mid-wicket to go with his six fours from 41 balls until Steven Mullaney bowled him.
After Moore survived a botched stumping chance on 47 he took up the attack as he was joined by Steven Croft, who added a further 41 in four overs that seemed likely to take Lancashire past 200.
But after paddling Andy Carter for his eighth boundary, the opener tried to repeat the trick and found the hands of Gurney at short fine leg, before Croft (31 not out) hit 10 off the final five balls.
