Leinster have almost certainly secured a a home semi-final in the Rabo Pro 12, after winning 22-20 away to Ulster last night.
Nearly 17,000 people showed up for the official opening of the redeveloped Ravenhill, but the Boys in blue ruined the part by taking the points.
The turning point came in the 17th minute, as Tom Court was sent off for a spear tackle on Devin Toner.
Leinster went in at the break 9-8 in front through three kicks from Ian Madigan.
The extra man begin to show in the second half, as Shane Jennings ran in Leinster's only try after an hour.
Jimmy Goperth added another three points with ten minutes remaining, to lead 22-14.
Paddy Jackson converted twice to cut Leinster's lead to two points with two minutes remaining, but the Ulstermen just couldn't take the lead.
The losing bonus point for Ulster almost guarantee's them a spot in the semi finals, and a likely meeting with Leinster at the RDS in the final four.
