A goal in the 59th-minute from Lorcan Dolan proved crucial as 14-man Moate CS pipped Colaiste Eoin at Glenalbyn.
Eoin were largely on top in the opening half with Jude Mac Suibhne and Daniel O Caoimh both impressing to lead 1-3 to 1-1 at the break.
They stretched their lead with points from Conall O Neill and Grahame O Fogartaigh but a penalty from David McCormack had Moate within a point.
When Eamonn McCabe was sent off, Moate's chances were dealt a blow but Dolan delivered his late, decisive goal.
