Samoa fly-half Tusi Pisi kicked five penalties in his side's 15-0 victory over struggling Italy at Apia Park on Saturday.
The result follows the Azzurri's loss to Fiji last weekend to round off a poor year in Test rugby so far.
Pisi made them pay with five successful kicks as Samoa responded from their surprising 18-18 draw with Tonga last weekend.
The former Hurricanes number ten landed four of his penalties in the first half to leave the Italian chasing the scoreboard in tough conditions.
The win certainly isn't of character for Samoa given that this was their fifth victory over Italy in six meetings, but they would have expected a greater threat from their visitors.
Italy have now lost their last eight matches going back to last November, an unwanted record for Jacques Brunel heading into the Rugby World Cup.
