Ospreys ran in nine tries to secure a bonus-point win against French side Grenoble in the European Challenge Cup.
Kieron Fonotia scored his first try for the Ospreys before Sam Parry crossed to extend their lead, but Clement Gelin forced his way over for the hosts.
Alun Wyn Jones restored Ospreys’ 14-point advantage, and Josh Matavesi touched down just before the break.
Dafydd Howells and Keelan Giles both scored twice, and Dan Biggar’s late try capped his 19-point contribution.
The game had been scheduled to take place on Thursday at 19:45 GMT but was postponed by nearly 24 hours because of a frozen pitch at Stade des Alpes.
Ospreys’ victory was only their second in France, their first a 31-13 win against Lyon in the first round of Challenge Cup matches in October.
