Over 1,500 spectators witnessed a low-key encounter in Tipperary Town as the champions, after pulling clear to lead 0-8 to 0-5 at half-time, were rarely troubled by an Éire Óg outfit over-reliant on midfielder Pádraic O’Dwyer.
Fiachra O’Keeffe’s goal six minutes after half-time put Clonoulty-Rossmore in the driving seat as they led by eight points, 1-11 to 0-6.
Kev Fox hauled Éire Óg back into contention with a goal midway through the second half and when 47-year-old John Quinn drilled over a 49th minute point, the Annacarty outfit were within four points.
But Clonoulty-Rossmore comfortably held their opponents at bay until the finish.
Éire Óg finished with 14 players after sub Brian Ryan received a straight red card in the final minute.
Clonoulty-Rossmore added real gloss to the final scoreline when sub Conor Ryan netted deep in stoppage time before top scorer Tom Butler scored his sixth and final point.
