SINCE the USA Sevens tournament first became a regular fixture on the IRB's Sevens World Series nine years ago, it has produced its fair share of surprise results.
New Zealand seem to have put their stamp on the lion's share of tournaments and venues down the years, but in the US they have won only two of nine Cup battles waged, the most recent back in 2008.
Samoa have also won the title twice, including last year in a heart-stopping final against the kiwis, and the only other side to have won on US soil more than once is Argentina.
The Pumas have only two IRB Sevens Cup successes to their name, in 2004 and 2009, and both of them were won in the US.
"In 2004 it was hugely important for Argentina, because it was our first tournament victory," said current coach Andres Romagnoli, who was part of that victorious side in Carson, Los Angeles.
It's always nice to come back to the US because this is where we have had our success stories — in LA and then in San Diego in 2009. And now we want to win here in Las Vegas. In 2004 we played some very good Sevens, we beat New Zealand for the first time (in the Cup final) and really played for each other."
