Munster’s bid for a third Interprovincial Championship victory in four years was crushed decisively by Leinster’s young guns on the Sandy Hills at Rosapenna Hotel and Golf Resort in Donegal.

Tullamore’s Stuart Grehan was declared the winner after torrential rain and southerly winds forecast to gust over 100kph saw the CityNorth Hotel sponsored East of Ireland Amateur Open reduced to 54 holes for the first time in its 75-year history.
