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.
