Leinster produced a dominant display to win 68-14 against the Ospreys.
Leinster warmed up for next weekend's Champions Cup final in style with a 10-try victory over Ospreys in Dublin.
The bonus-point win secured second place in the United Rugby Championships table and a home quarter-final against the Lions.
James Lowe marked his return from injury with a try, while Jordan Larmour scored twice on his first appearance since December.
The result gives Leo Cullen's side plenty of momentum as they prepare to face Bordeaux in the Champions Cup final weekend.
