The visitors got off to a bright start and the opening try of the evening came after two minutes when fly-half Jonathan Sexton capitalised on some excellent work by the pack to touch down in the corner. The St. Mary's man missed the conversion but made amends in the 16th minute when he slotted home after Felix Jones sprinted clear to score.

Devin Toner was the instigator in that move by snatching a lineout and feeding scrum-half Chris Keane who distributed the sweetest of passes to Sexton. Brian O'Driscoll then released Jones on the flank and the former Ireland Under-20 winger completed the move in the corner.

Leinster took that 12-0 advantage into the interval but Treviso, to their credit, fought back with converted tries on 43 and 50 minutes.

The visitors pressed to regain the lead and it was substitute Rob Kearney who gathered a well-worked kick and chase to race clear of the Italian defence. Felipe Contepomi added the points to conclude a positive week's work for the Celtic League champions in front of an animated home crowd.
