Muckamore secured their 12th win of the league campaign to move 12 points clear at the top of Section One after a bizarre win at home to Donacloney Mill.
Batting first DM were skittled for just 39, losing 8 wickets for 17 runs having been 22 for 2 at one stage.
Sathish Suresh took 4 for 2, while there were two wickets apiece for Shane Henderson and skipper Neil Gill - including the big one of overseas player Peet Pienaar.
When the home side reply reached 22 for 0, it seemed a straightforward task, but three wickets for Robin Sinton and two for Aaron Kennedy saw them spluttering at 31 for 5, before sanity resumed, eventually sealing the 5-wicket win in the 7th over.
