UCC made history by winning the club's first AIB League play-off title with their second surprise result in the space of six days.
Last Sunday 'College beat Buccaneers in their first ever Division Two semi-final and this afternoon, in the decider at Donnybrook, they got the better of another promoted side.
The Cork side's pack was awesome in front of man-of-the-match-winning scrum-half Sam Cronin.
A try from Eoin Ryan and a Mark Connolly kept Munsters in contention but six penalty successes from Gavin Dunne won the day for 'College.
Scorers:
UCC: Pens: Gavin Dunne 6
Young Munster: Try: Eoin Ryan; Pen: Mark Connolly
