The Ospreys suffered a chastening defeat in Scotland that hindered their chances of retaining the Welsh Shield.
Toby Booth headed to the Dam Health Stadium with a strong side - with 10 of his starting XV being Wales internationals. However, they were no match for Mike Blair's side - who marked the coach's final home match in charge in fitting fashion.
Ben Vellacott ran in the hosts' opening try before Dave Cherry added a second.
