Leinster secured second place in the BKT URC table with a facile 68-14 victory over Ospreys at Aviva Stadium.
The Welsh outfit were already out of contention and Leo Cullen’s side raced into a 28-7 first-half lead.
The hosts, for whom wing Tommy O’Brien was a late withdrawal, added another six tries after the break to overtake Stormers, who lost to Cardiff on Friday night.
The defending champions scored 10 tries in total, including a hat-trick from Joe McCarthy.
The home side made a strong start with two tries inside the opening seven minutes.
McCarthy barged over under the posts from close range before Max Deegan (above) went through following a drive from a line-out, and Harry Byrne successfully landed both conversions for a 14-0 lead.
Leinster continued their momentum as flanker Josh van der Flier touched down after being picked out on the overlap by Jack Conan before Jimmy O’Brien then ran clear to secure a bonus-point try in the 23rd minute.
Ospreys finally stemmed the flow just after the half-hour mark when Huw Sutton crashed over from Rhys Davies’ offload, but the Irish province still took a comfortable 28-7 lead into half-time.
Leinster then took the game away from the Ospreys with a ruthless second half. Garry Ringrose ran in, winger Jordan Larmour then chasing down a kick through before McCarthy powered across in the 56th minute.
Larmour added another try just before the hour, running in from his own half, with McCarthy completing his hat-trick and James Lowe scoring from wide for his 69th Leinster try to tie the club record.
Ospreys got a late scant consolation try from Dan Edwards.
Attention now turns to next Saturday’s Champions Cup final where Leinster take on holders Bordeaux-Begles in Bilbao.
