Roland Suniula and Taylor Mokate both scored tries to help the USA Eagles beat Georgia 36-20 on Saturday.
Mike Petri and James Paterson also scored tries for the United States, coming off a 28-25 loss to Canada.
The Americans dominated at the high-altitude venue in the hotbed of US rugby after inserting Mokate at number six and Suniula at fly-half, where he played for the Eagles at the 2011 World Cup.
Suniula, born in Samoa and raised in New Zealand, gave the Americans an 8-0 lead with his try and produced a line break to set up Petri's try on the way to a 28-8 half-time lead.
Mokate scored his try in the first half and Paterson added his to produce the final points of the game after two Georgia tries pulled the visitors, who never led, back to 31-20.
The Americans will entertain Italy next Saturday at Houston, Texas, while Georgia play Canada next weekend.
