In the end, it was Kieran Marmion's finishing touch at the end of a superbly-worked team try which separated the sides at the Sportsground.
It finished 7-6, but it was a titanic 'Munster Schools Senior Cup' type of 7-6 rather than a negative spectacle. With the win, Connacht extend their lead at the top of the Guinness PRO 12 table to four points, with Leinster picking up a bonus point for their troubles.
An incredible rearguard effort by the men from the wesht was enough to hold Leinster out, with bodies being thrown on the line quite literally; the final five minutes was played almost exclusively on Connacht's tryline.
A miracle turnover by Eoin McKeown after a sustained spell of Leinster pressure sparked jubilant scenes, and when the final whistle blew in Galway, all hell broke loose.
