EFFIN completed a rollercoaster journey to the title before a huge crowd in Newcastle West, where they beat Kerry senior champions Ballyduff to claim the title.
A superb display at centre-back by Limerick senior goalkeeper Nicky Quaid inspired this latest triumph for a club who won their local junior championship just 12 months ago.
Ballyduff, the red-hot favourites, set a cracking pace with three points without reply by Pat Joe Connolly inside seven minutes.
Three points by Nicky Quaid helped tie it up at 0-4 each before Ballyduff went three clear again through Mike Boyle, Barry O'Grady and Aidan Boyle.
Two frees, this time by Tommy Quaid, and one from play by Damian Moloney left a point between them at half-time, 0-8 to 0-7 in favour of the Kerry side.
A Tommy Quaid free levelled things again and Effin led for the first time thanks to a point by Timmy Rea.
Substitute Enda Kelly and a free by Tommy Quaid had Effin three in front before Mike Boyle had Ballyduff's first point of the half 10 minutes from the end and Aidan Boyle had another to leave only one between them.
Two more points by Timmy Rea and another by Moloney wrapped it up for Effin. The Quaid brothers, Nicky and Tommy, John Dillon, Mike and Timmy Rea and Damian Moloney starred for Effin with Jason Bowler, Ally O'Connor, Padraig O'Grady, Bobby O'Sullivan and Pat Joe Connolly shining for a Ballyduff side attempting to become the first Kerry team to win a Munster hurling title.
