Mayo seeking lucky 13 for place in Connacht history books
It started with the closest of calls against London four years ago and is now poised to take Mayo into uncharted territory.
If Mayo record a 13th successive win in the Connacht championship on Sunday, they will secure a provincial five-in-a-row for the first time - Galway (1956-60) are the only county to achieve that feat in Connacht.
Mayo experienced their last defeat in Connacht in 2010 when Sligo - whom they play in the decider on Sunday - beat them by four points in the semi-final.
The following is the tale of woe for all Mayo's Connacht rivals since then.
The margin was down to four points this year, but it was still painful for Galway, who suffered their fifth successive championship defeat against Mayo, a fate not endured for over 100 years.
Galway have lost four times to Mayo (2011, '13, '14, '15) in the latter's historic run, the most overwhelming being a 17-point defeat in Pearse Stadium in 2013.
They have lost three times to Mayo in the last four years, two by narrow margins (one point in 2014 and two points in 2011. Mayo won by 12 points in 2013.
Despite coming so close to unhinging James Horan's management in his first Championship outing in 2011, taking Mayo to extra-time, few would have thought that the next clash between the teams would be in the Connacht final.
However, London's best ever Connacht Championship yielded wins over Sligo and Leitrim in 2013 before Mayo intervened and handed out a 16-point thrashing.
They have had only one collision with the Mayo juggernaut and came away feeling sore, losing the 2012 Connacht semi-final 4-20 to 0-10.
A sign of things to come next Sunday? They set themselves up defensively in the 2012 Connacht final, restricting Mayo to 0-12. It wasn't good enough, however, as Sligo only mustered 0-10 themselves.
They lost to Mayo by 4-18 to 0-8 last year.
