Bayonne signed off their Amlin Challenge Cup campaign in some style with a comprehensive victory over Italian side Rugby Mogliano at the Stadio Maurizio Quaggia.
London Wasps had already qualified for the quarter-finals from this pool and Bayonne had nothing to play for but pride but they secured a bonus-point try victory before half-time against the Italian part-timers.
Fly-half Jaques Louis Potgieter ended the game with a personal tally of 15 points, including a try, as the French Top 14 side kept their hosts scoreless.
Wings Bastien Fuster and Marvin O'Connor, Potgieter, full-back Sam Gerber and scrum-half Mike Phillips all crossed for tries in the first half to make it 33-0 at the break.
Wing Fuster claimed his second try in the second half, while centre Gabi Lovobalavu and replacement centre Thibault Lacroix crossed for two more tries for the French side.
