Five points were the difference in the victory.
O'Dempsey's got their Laois Senior Football Championship underway with a win in Portlaoise last night.
At half time there was just a point between last year's beaten finalists and Graiguecullen.
However O'Dempsey's pulled away in the second period to win on a final scoreline of 1-11 to 1-6.
Peter O'Leary is part of the O'Dempsey's management team - he says their scores just before half-time dealt a psychological blow to their opponents:
