try Leinster overpowered Glasgow Warriors to oust the reigning champions and cruise into their first United Rugby Championship final.
They will host the Bulls next Saturday at Croke Park, after Jake s men outgunned South African rivals, the Sharks, 13.
Glasgow responded to conceding a try to Dan Sheehan after only three minutes by scoring at the other end immediately through George Horne.
But Leinster added three to a greater extent of their own through Jamie Osborne, Thomas Clarkson and Sheehan by time
half tries from Osborne and Ciaran Frawley extinguished hopes of an unlikely comeback before consolations from Jamie Dobie and Sione Tuipulotu.
It means Leinster, who had endured three straight URC final defeats, and wrenching losses in the latter stages of the Champions Cup, head into next s final, which kicks off at 00 BST, still on course for a ninth title but first in this format of the competition.
The Irish additional started as favourites after ending the regular season top of the table and having thrashed Warriors 0 in the Champions Cup final eight weeks ago.
s standards had dropped since their own defeat by Northampton in the European semis, with a shadow Glasgow supplementary proving tougher opponents when going down 5 in the URC three weeks ago.
The hosts, though, were immediately in the ascendency and Jamison Park floated a pass for hooker Sheehan to exploit a gap and touch down under the posts.
Sam Prendergast added the extras, but Glasgow responded instantly. Tuipulotu sent Kyle Rowe racing down the left wing and his kick inside sent Horne diving over the line unchallenged.
The half missed a fairly simple conversion, but the try had Glasgow dreaming of a first win by a Scottish team club or national at the Aviva Stadium.
However, despite Prendergast having one try ruled out for crossing, the Leinster half was soon adding to the scoreline as the hosts were given a penalty in front of the posts.
After a crunching tackle halted s Tom Jordan, Leinster exploited the space behind and Osborne raced through under the posts only for s pass to be ruled forward.
Osborne did not have to wait long for his try, the centre racing down the left wing to touch down in the corner from James s offload.
