Munster posted the first try on 11 minutes, a score created by Anthony Horgan. The veteran winger hacked ahead inside his own half, gathered before laying off smartly to Neil Ronan who sprinted 35 metres unopposed to the line.
The extras were added by Paul Warwick, who was instrumental in setting up good field position in the build-up to the European Cup holder's second try. Awarded a five-metre scrum, Munster opted to pick and drive. Donnacha Ryan and John O'Sullivan made the hard yards before Frankie Sheahan picked form the base of ruck and drove over with Warwick making it 14-0.

It was close to 55 minutes before Irish returned to the red zone as Peter Stringer and Ronan O'Gara gave splendid direction behind a dominant pack. Earls then raised the roof on 61 minutes. O'Gara's distribution was quick and smart in the early phases, but it was the long and risky pass from Tipoki to the fleet-footed Earls that allowed the Limerick man take off close to the touchline. Earls chipped three Irish defenders before chasing and dotting down in the try zone.
O'Gara landed the difficult conversion and the Ireland out-half produced one of his trade mark cross-field kicks a minute from time for Earls who took a kind hop and crossed over in the corner. O'Gara closed a productive evening for the kings of Europe arcing a sublime touchline conversion.
