New Irish international Ian Madigan helped himself to all 22 points as he steered Amlin Challenge Cup quarter-finalists back to the top of the RaboDirect PRO12 with a narrow home win over Glasgow Warriors.
Madigan's vital 10 point contribution in the closing 10 minutes at the RDS enabled the reigning Heineken Cup champions to overtake their Scottish rivals at leapfrog them into first place in the PRO12 table to lead by a point with four games left to play.
Even though the Warriors outscored their hosts by two tries to one, it was Madigan's boot, in the continued injury absence of Jonny Sexton, that initially kept Leinster in the game. In all, he struck five penalties and converted his own try in the 22-17 triumph.
Leinster complete their build up to their European quarter-final clash with London Wasps at Adams park on Friday, 5 April with another home game on Saturday against Ulster - a repeat of last season's Heineken Cup Final at Twickenham Stadium when Leinster became only the second side to successfully retain the trophy.
As well as clinching the victory, and moving back to the top of the table, Leinster head coach Joe Schmidt will have been pleased to see Irish centre Gordon D'Arcy complete the full 80 minutes and Isa Nacewa and Kevin McLaughlin also return to action.
The directors of ERC voted unanimously at a Board meeting to postpone all decisions including the release of further instalments of ERC's distributable central revenues to the six shareholder countries until 19 February next when the Board will meet again to reconsider the issue.
