Andrew Conway’s try put Munster ahead but Cian Healy’s score levelled the game before Garry Ringrose’s touchdown left Leinster 17-13 up at the break.

Hanrahan landed a superb conversion from the left touchline but after Byrne’s 70th-minute penalty had extended Leinster’s lead to seven, the Munster fly-half couldn’t repeat the dose as he missed with the extras following Conway’s second touchdown.
