The USA booked their place at the Olympics in Rio in both the men's and women's Sevens this weekend.
The men's team beat Canada 21-5 in the final of the NACRA qualifying in North Carolina, while the women hammered Mexico 88-0.
In London last month, Mike Friday's team had become the first American side to win a World Rugby Sevens Series event, and they carried that form to the tournament in Cary.
After cruising into the final, they were able to race into a 21-0 half-time lead thanks to tries from Perry Baker, Danny Barrett and Maka Unufe, which were all converted by Madison Hughes.
The second half proved more difficult, with Canada coming back into it thanks to a Harry Jones try, while the USA lost Folau Niua and Chris Wyles to yellow cards.
However the Americans held on and join Fiji, New Zealand, South Africa, Great Britain, Argentina and Brazil in qualifying for Rio, while Canada will now enter the repechage tournament for a final chance to qualify.
In the women's tournament, Canada had already qualified on the World Sevens Series circuit, so the Americans cruised through the competition, culminating in a thumping win over Mexico in the final.
Mexico and Trinidad and Tobago will enter the repechage tournament.
