Leinster made a winning return to the RDS with a comfortable victory over Cardiff in Dublin. Sam Prendergast was the standout performer of the night, catching the eye with his control of the tempo and his attacking instincts. The province looked comfortable for long stretches in their first outing back at the Ballsbridge venue. Cardiff, for their part, left with little to show for a difficult evening away from home. The exact margin and the full list of scorers were not spelled out in what has been made public so far. The result keeps Leinster's momentum moving in the right direction as the fixture list thickens. Prendergast's growing authority in the number 10 shirt is bound to be a talking point among supporters in the weeks ahead.
