Leinster secured their fourth Guinness pro14 title in a row with a 16-6 victory over Munster in the RDS.
Munster were second best throughout as they 10-year trophy less drought continues while Leinster continue to build their domination.
Ross Byrne sent over two penalties in the fourth and 12th minute with Joey Carberry restoring parity for Munster with 14th and 40th minutes penalties leaving the score 6-6 at half-time.
However Leinster totally controlled the second-half with the first second-half scrum resulting in the game’s only try.
Seven second-half minutes had elapsed as Porter collected from the try, setting up another barrage on the Munster line as Jack Conan getting the ball down.
Ross Byrne added the two points.
It was Byrne who put the game beyond the Munster men, who were penalised for offside, with Byrne calmly stepping up to seal the victory and another Pro14 title.
