Yorkshire gained their first Twenty20 Cup win of the season when they beat Durham by nine wickets with 13 balls to spare in a nine-over thrash at Headingley.
Rain prevented any play until two hours after the scheduled start and Durham could only manage 65 for nine after being put in to bat.
At one stage they lost five wickets for seven runs off nine deliveries, three of them falling to left-arm spinner David Wainwright, whose figures of three for six in two overs were Yorkshire's best in Twenty20 cricket.
The only Durham batsman to make an impact was opener Scott Styris, who struck 27 off 16 balls with two fours and two sixes, both of the big hits coming off consecutive balls from Anthony McGrath which sailed high over mid-wicket.
Wainwright joined the attack at 45 for two in five overs and his second delivery trapped Styris lbw as he attempted a reverse sweep. Two balls later he had Ottis Gibson caught at long-on by Andrew Gale and he picked up his third dismissal in his next over when three wickets fell, Gareth Breese slicing a catch to point and Garry Park and Paul Wiseman both being run out.
Craig White got the Yorkshire innings off to a perfect start by slapping Gibson's first ball over mid-wicket for six and with Gerard Brophy also picking up a boundary 14 runs came off the first over.
White was caught behind by Phil Mustard off Steve Harmison to make it 19 for one but Yorkshire romped home through an unbeaten second-wicket stand of 47 between Brophy and McGrath.
The biggest hit of the match came when McGrath pulled Harmison high into the West Stand for six and with both batsmen going well Yorkshire never looked in any danger of losing, Brophy finishing with 31 off 21 deliveries with five fours and McGrath 20 from 14 balls with one four and one six.
The Yorkshire victory was watched by a 4,229 crowd and the win moved the Tykes into fourth place in the north division table with three games remaining.
