DOON appeared in their seven successive Limerick Premier U21 hurling championship final on Sunday.
They endured four defeats but are now basking in the glory of three straight county title wins.
Joint captains Jack Ryan and Chris Berkery accepted the winning trophy from Limerick GAA treasurer Liam Bourke.
The duo will be the only players from the starting team overage next season.
Ryan scored two goals in the 3-19 to 1-14 final win over Na Piarsaigh and afterwards spoke about the importance of turning underage success into senior silverware.
