Munster missed a great chance to consolidate a spot in the top four
Leinster survived a late Munster onslaught to claim a crucial Pro12 victory that moves them top of the table following Connacht's loss last night.
Johnny Sexton scored all of Leinster's points and had them leading at the break thanks to a strike from the tee and then touching down with the game's opening try just before the interval.
Johnny Holland got Munster off the mark, with two penalties of his own in the first half.
The battle of the two Johnnys re-commenced after the break, with the Munster version striking first for a try soon after the restart to leave Munster three points to the good.
Sexton added two more penalties to reverse the deficit and hand Leinster the initiative before there was one more twist in the tale with Cian Healy being binned late in the game, with Munster applying serious pressure to the line in the dying stage, but to no avail as a knock-on cost them possession, and ultimately, the game.
