Munster took a giant step towards winning the Magners League title as they clinically despatched their arch-rivals Leinster in front of a capacity Thomond Park crowd.
Second-half tries from Keith Earls and Denis Fogarty helped the European champions storm to a deserved 22-5 victory but this so-called 'Battle of Ireland' really was definitely a tale of two number 10s.
Leinster's Felipe Contepomi, who is leaving for Toulon in the summer, had a nightmare outing, missing four kicks at goal and struggling throughout to direct his team's attacks.
In contrast, Munster playmaker Ronan O'Gara marshalled his side superbly and his 12-point kicking contribution laid the foundations for a win which has Tony McGahan's men seven points clear at the league's summit.
England Under-18 head coach John Fletcher insists his young side will be better for the experience after beating Italy in the bronze final to round out their 2015 Rugby Europe U18 Championship campaign in style.
