Ian Madigan kicked six penalties as Leinster beat Bath 18-15 in their European Champions Cup quarter-final in Dublin.
Bath scored the only two tries of the match, with George Ford diving over in the first half and then creating Stuart Hooper's try early in the second.
The English club did well to get back within three points of their opponents, but were made to pay for their indiscipline, especially at scrum time, by the boot of Madigan.
