Barbieri struck five minutes before half-time when he powered over from a scrum, ensuring his team were rewarded for their dominant set-piece, and as the final quarter arrived Esposito crossed to leave Edinburgh with too much to do.

Ian McKinley contributed three penalties, while all the visitors could muster in response were six points from the boot of Jason Tovey.

Treviso finished the stronger team and wing Luca Sperandio almost added a third try at the death.
