Fiji avenged their defeat at the hands of Samoa last weekend to beat their fellow islanders 38-24 in the final and take the Cup title at the Steinlager USA Sevens.
The victory means that the four IRB Sevens World Series Cup titles so far this season have each gone to a different team with the Fijians joining South Africa, New Zealand and Samoa as Cup winners. The Fijians now join New Zealand at the top of the Series standings on 60 points, four ahead of South Africa on 56.
Fiji were rampant in the final, Semisi Naevo and William Ryder again in irresistible form to guide Waisale Serevi's men home.
Two first half tries by the fantastic William Ryder, plus efforts by Nasoni Roko and Etonia Naba to Samoa's sole score by Uale Mai took Fiji to a 26-7 lead at the break.
Although the Samoans hit back in the second half with tries by Timoteo Iosua and Jerry Meafou, scores for Semisi Naevo and Lepani Nabuliwaqa took the Fijian total out to an unassailable 38-24.
South Africa take Plate title
The Boks of South Africa had to come from behind in the penultimate match at PETCO Park but did so to beat Scotland 28-19 and take the Plate trophy. In doing so they also take eight valuable points for the IRB Sevens World Series to lie four points behind leaders New Zealand and Fiji.
Gcobani Bobo gave Paul Treu's side an early lead in the final but Scotland hit back through Mike Adamson and then Mark Robertson, following good work from wing Thom Evans, to lead 14-17 at the break.
South Africa dominated the second half with three tries from Mpho Mbiyozo, Howard Noble and captain Jonathan Mokuena to Scotland's one, scored by Lee Kibble, although Scottish coach Stephen Gemmell will be heartened by his side's considerable improvement since the start of the season.
France earlier made a first semi final of the season after a dramatic late try by Farid Sid saw off Australia. Fiji beat New Zealand for the second consecutive week to reach the finale.
On the same weekend that their senior XV a side team qualified for the Rugby World Cup in France this year the Tongan Sevens team beat Argentina 22-17 to take the Bowl title in San Diego and two points for the 2006/07 Series. Argentina went up through Alfredo Lalanne but Tonga hit back with two tries from Siale Lolohea. The islanders then built on their half time lead with a score from Sione Langatau only for Argentina to storm back to parity with tries by Lalanne and Amelong to take the game into extra time. Tomasi Funaki went over for the sudden death try.
Dana Teagarden took charge of the match becoming the first woman to referee a senior men's competition final.
Home favourites the USA fought off the challenge of series core side Portugal to build on a 14-5 half time lead and run out 26-5 winners. The Eagles went ahead through forward Todd Clever, Pedro Leal pulled one back for Tomaz Morais' side before Takudzwa Ngwenya scorched home for the 14-5 lead at the break. The second half saw Al Caravelli's side maintain their stranglehold and delight the crowd with further tries for Naqica and Osborne to hammer home their authority.
Earlier the USA overcame the West indies 17-0 to reach the final, while Portugal were too strong for Chile and ran out 42-10 winners, the impressive Pedro Leal grabbing a hat trick.
