AS well as Ireland's seniors, the Irish Women's and Clubs sides registered weekend successes, too.
Indeed, the only blot on the otherwise perfect landscape was Ireland Under-20s' 16-0 defeat by Wales in dreadful conditions on Friday night at Dubarry Park.
Ireland's performance, too, was abject and having done the hard part of the job in restricting wind-assisted Wales to a 3-0 lead – an Ethan Davies penalty – they shipped 13 post-interval points.
Welsh centre Steffan Hughes scored the night's only try, with Davies adding the 63rd minute conversion to complement his three penalties.
No such problems for Ireland Women who added Wales' scalp to that of Scotland, making it two out of two in their defence of the Grand Slam.
Having whipped Scotland 59-0, Friday night's match at Ashbourne was altogether closer. It finished 14-6.
With elements behind her, Welsh centre Robyn Wilkins kicked two first-half penalties.
But the second-half story was one of almost total Irish domination with Munster full-back Niamh Briggs landing a hat-trick of goals and her provincial colleague Heather O'Brien forcing her way over from close range for the only try.
The Irish Clubs' International XV won the Dalriada Cup by beating their Scottish conterparts 28-3 on Friday night at a sodden Temple Hill where Old Belvedere full-back Danny Riordan bagged two first-half tries.
Captain Gerry Hurley (Cork Con) added a third and replacement Declan Lavery (Old Belvedere) a fourth in the second period, with David Joyce (Clontarf) kicking two penalties and a conversion.
