Claremorris turned on the style in Concannon Park on Sunday to record an eight goals to one victory over luckless Kilmore in their final home league game of a remarkable season.
Brian Gallagher was the star of the show, scoring four of the goals and claiming one assist in a fine overall display.
But there were others to catch the eye in what was a dominant display over the Erris men.
Kilmore travelled with the bare 11 players as the squad was depleted due to injury and other commitments.
They shut the home side out for just over 10 minutes before Gallagher opened the scoring, lobbing the ball over the out-rushing Kilmore 'keeper Gary Keane and into the net.
Soon it was 2-0, the lanky striker with a simple side-footed finish after he rounded Keane to give the perfect conclusion to Danny Broderick's superb through ball.
Gallagher had secured his hat trick by the 20th minute when he took down Andrew Shally's excellent cross-field delivery, turned his marker and shot confidently past Keane to make it 3-0.
The striker had another before half time, but not before Jan Rada had made it 4-0 in the 36th minute. The ball went in past Keane at the near post as Czech midfielder Rada got a touch to Kevin Costello's cross from the right wing.
On the stroke of half time Gallagher rose majestically to head in Broderick's corner, ensuring the home side of a 5-0 lead at the break.
Kilmore found some energy for the start of the second half and after Darren Keane forced Clarmorris 'keeper Shane Macken into a save in the very first minute, they pulled a goal back when Tommy Murphy finished well when he latched on to a long through ball.
However, the goal only served to reawaken Claremorris. After a number of missed chances, Danny Broderick restored the five-goal lead in the 61st minute when he finished with aplomb to the bottom right corner of the Kilmore goal from Gallagher's low delivery from the left.
There were two more goals for the home side to celebrate before the end, Andrew Shally and substitute Fergal O'Connor drilling in shots from the edge of the area, the former going high and the latter going low but both with the same result.
It capped a fine season for the south Mayo club, and captain Niall Kitching was presented with the Premier Division trophy after the game by Mayo League chairman, Padraig McHale.
