Ireland’s defence of their Six Nations crown remains alive but only just after a laboured bonus-point win over Italy.
Quinn Roux, Jacob Stockdale, Keith Earls and Conor Murray scored the tries as the champions held on for victory.
Italy led at half-time with tries from Edoardo Padovani and Luca Morisi but were unable to score after the break.
Replacement Ian McKinley missed a stoppage-time penalty as Italy could not even salvage the losing bonus point their efforts deserved.
