Madigan stars for Leinster
Half-time replacement Ian Madigan sparked Leinster into life as they came from behind to record a 26-7 bonus point victory over Aironi at the RDS.
The 22-year-old came off the bench and was instrumental in Leinster's best attacking play, scoring the first of their four tries in the 48th minute.
The province had been in a sticky situation after Nick Williams' converted try earned a surprise half-time lead for the Italians, who have yet to win an away game in the RaboDirect PRO12. But Leinster knuckled down in the second half and a last-minute try from stand-in captain Rhys Ruddock was the reward for the persistence shown in difficult wet conditions.
