Hi °C | Lo °C 
A late David Kearney try finally broke battling Aironi's resistance as Leinster secured an uninspiring 21-16 victory at the RDS.
Nick Williams' 35th-minute try gave the Italians a 10-3 half-time advantage and had them dreaming of their first ever Magners League win.
But second-half touchdowns by Niall Morris and Kearney, allied to 11 points from man-of-the-match Isa Nacewa, saw a youthful Leinster grind out the victory.
Bottom side Aironi at least took something from the match, with Paolo Buso's last-minute penalty securing them their first league point earned outside Italy.
