Clontarf remain in contention for the Premier title after beating third placed North County in a rain affected contest at Castle Avenue.
Conor Kelly's unbeaten 47 saw Clontarf make 95 for 1 in 11 overs - the contest having originally been reduced from 20 to 15 due to rain.
Kelly hit 5 fours and a six in his 32-ball knock, adding 68 for the first wicket with Bill Coghlan (25).
DLS adjusted the North County target upwards to 107, and they were dealt what proved to be two decisive blows by Kelly (2-18), who dismissed Jamie Grassi in the first over and then overseas professional Malcolm Nofal.
Safdar Ali top scored with 35 as County finished 24 runs adrift on 83 for 1.
Clontarf are now 12 points behind leaders Merrion with two games to play.
The teams are scheduled to meet at Anglesea Road in the final match of the season on September 8th in what is likely to be a title decider.
Merrion take on The Hills this Saturday, while Clontarf's scheduled game with YMCA having to be refixed due to their involvement in the All-Ireland T20 finals day.
