Alesana Tuilagi scored a hat-trick as Samoa stormed to a dominant 49-12 bonus-point victory over Namibia in Rotorua.
Making their first appearance of the World Cup, Samoa – fielding the same starting 15 that stunned Tri Nations champions Australia in July – showed threats across the field that will ensure pool D opponents South Africa and Wales take notice.
High on those sides' agenda will be preventing opportunities to Tuilagi, the 119kg powerhouse that caused nightmares for the Namibian defence throughout the encounter.
Adding to Tuilagi's efforts were a try to scrum-half Kahn Fotuali'i only 49 seconds into Samoa's 2011 campaign, while fullback Paul Williams returned from the sin bin to also cross over.
The Samoans, running with the breeze in the first half, led 25-0 thanks to two of Tuilagi's tries and Fotuali'i's first-minute individual effort.
Fielding a poor Namibia clearance, Fotuali'i tip-toed down the right touch, beat two defenders and sent the large Samoan contingent in the crowd into raptures.
Tuilagi had plenty of help with his five-pointers coming through fine hands to put him into space, in each case by the impressive George Stowers.
The opening 40 minutes, utterly dominated by Samoa with 73 percent of territory, ended with fullback Paul Williams being unfairly judged to have made a dangerous hit on Namibia fly-half Theuns Kotze and sent to the sin bin for 10 minutes.
Tuilagi sealed his hat-trick midway through the second half, again with a simple path to the left corner for a bonus point.
And Williams came back on to stride by three defenders and record his side's fifth.
Namibia never stopped working and were duly rewarded with the best try of the match – a 70 metre build-up where wing Llewellyn Winkler chipped for himself, gathered and fed centre Danie van Wyk to run in.
Samoa were not finished, however, gaining a penalty try thanks to their dominant scrum.
The final say went to Kotze, who dummied and went over in the 79th minute to show he has a try-scoring verve to match his drop-goal spree in the opening loss to Fiji.
In what is essentially a quarter-final qualifier, Samoa will face Wales in Hamilton on Sunday, while Namibia's arduous task of playing four matches in 16 days continues against the might of South Africa in eight days' time.
