Leinster and Ireland scrum-half Tania Rosser scored a try in each half to seal the win, and Jackie Shiels added the extras. Jean Lonergan scored Munster's only try. The two sides are however still expected to meet again in this year's final, with both having only one game left each.
Ulster beat Connacht 14-0 with substitute winger, Christine Robb, grabbing a brace after coming on early in the first half. Rachel Reid converted both.
