Ronan Watters was the star of the show as Leinster 'A' thrashed Ospreys Development to maintain their unbeaten start to the Celtic Cup season.
The visitors demolished their hosts in a ruthless first 40 minutes which saw them take a 26-0 lead into the interval. Impressive openside flanker Watters opened the scoring as he powered his way over from short range after Ospreys' Morgan Morris had been sent to the sin bin for a professional foul.
The hosts were then reduced to 13 men as Rhys Davies was also handed a yellow card for illegally slowing the ball down. Leinster piled on the pressure and Dan Sheehan touched down as a result of a well-worked driving lineout.
Adam La Grue crossed at the far right-hand corner after some neat handling to extend Leinster's lead before Watters grabbed his brace.
Tom Williams claimed a try back for the hosts in the early stages of the second half but their comeback was short-lived, as Leinster added two more tries, the sixth the pick of the bunch as Liam Turner burst through to run in unopposed. Joshua Moore managed to claw a try back for Ospreys but Leinster hit back through Paddy Paterson.
Leinster were over again courtesy of Gavin Mullin who showed great pace to touch down with full-back Rob Russell completing the scoring for the visitors. Kieran Williams and George Gasson had late consolation tries for the Welsh side.
