Saracens rebounded from an opening defeat to Racing 92 by hammering a depleted Ospreys side 44-3 in the European Champions Cup.
The holders have endured a miserable time of it lately after being hit with a mammoth £5.36million fine and 35-point Premiership deduction for breaching salary cap rules during the past three seasons.
But Elliot Daly impressed on his debut and England team-mates Mako Vunipola and George Kruis returned in a six-try showing.
Jack Singleton, Alex Lewington and Rotimi Segun (2) all touched down before a penalty try and a score from Richard Barrington put an Ospreys side devoid of Alun Wyn Jones, Justin Tipuric, Gareth Anscombe and George North to the sword.
