Leinster closed out the round-robin phase of the IRFU Women's Interprovincial Championship with a 20-13 win over Munster at Irish Independent Park.
Ben Armstrong’s unbeaten side are now seeded first and will play fourth-placed Ulster in their semi-final on September 14th.
Connacht’s 20-19 defeat of Ulster at Queen’s University means they will play Munster in the other semi-final.
Leinster’s multi-phase attack teed them up for their first try as a tip-on pass from Jeamie Deacon helped put Megan Williams over in the corner.
Fiona Reidy responded with Munster’s only score of the first half.
Assured kicking from Hannah O'Connor and a Juliet Short try pushed the visitors further clear before Munster rallied with a try from pacy winger Laura Sheehan.
O’Connor’s 10-point haul keeps her at the top of the points-scoring charts in this year’s championship.
Connacht’s campaign sprung into life with a win in Belfast.
Ulster started the better side and looked on course after a brace of tries from hooker Stacey-Lea Kennedy helped them to a 12-8 half-time lead.
Full-back Mairead Coyne formed an impressive back-three for Connacht with Aoibheann Reilly and Alison Miller and it was Coyne who scored their first try of the championship.
Reilly was next to cross before Laura Feely’s try and a conversion from Méabh Deely pushed them eight points clear.
Lauren Maginnes’ try came in the last minute.
Ulster captain Neve Jones is glad there are more games to come in the reformatted competition.
"Having the five games this year is going to improve women’s rugby across the whole island," she said.
"It gives girls more of a chance to play at a higher level. It’s not just three games and then you’re done for the year. The semi-finals and finals give girls something to work towards."
