The USA made history at Twickenham as they won the final leg of the 2014-2015 HSBC Sevens World Series on the day Fiji won the overall title.

While Fiji won the war but not the battle as they were dumped out in the semi-final stage by Australia, it was the USA who emerged from London taking the final tournament title of the year thanks to a 45-22 win over Australia.

In the week the USA were given the 2018 Sevens World Cup, Sunday saw another huge milestone for American rugby as coach Mike Friday's side secured their first ever tournament win. It was a feat which surpassed their previous best finish of runners-up when they reached the final of the Adelaide Sevens in 2010.

Australia could not match the USA's immense power but they did draw first blood when Nicholas Malouf dodged around the outside to score in the early seconds of the match. Australia's joy proved to be short-lived as Madison Hughes, who had excelled throughout the whole tournament, and Danny Barrett crossed in quick succession.

The USA then scored a third through Barrett, who crossed in the same corner as his first, as Friday's men edged into a 14-point lead. But in a see-saw of a match, Australia pinned them back with Lewis Holland crossing soon after only for Maka Unufe to re-establish the USA's lead with a powerful score.

America went into the break with a 26-10 advantage and they soon stretched that margin with the remarkable Perry Baker scoring a superb solo effort. Australia cut the deficit with Lucas scoring but Unufe danced his way through the Australia defence to keep the USA out in front. Australia's Sam Myers scored a late consolation score but it was Saracens' Thretton Palama who had the final say when he powered away for another American try. 

In reaching the final, America had dumped England out of the tournament at the semi-final stage with Madison Hughes (two), Perry Baker (two), Andrew Durutalo and Carlin Isles (two) all crossing as they stunned the hosts with a ruthless display to win 43-12.

Australia secured their passage to the final thanks to a 33-7 win over Series champions Fiji in the semis. They clocked up five tries in total with Pama Fou, Ed Jenkins (two), Lucas and Malouf all scoring.

Hosts England faced Fiji in the third-fourth play-off and it was the series champions who prevailed 26-12 despite spending the first two minutes of the second-half with six men. England went into the break 12-7 to the good thanks to scores from Tom Bowen and Richard de Carpentier - with Fiji's score coming from Aisake Katonibau - but it was the Islanders who pulled away in the second-half. Osea Kolinisau scored first with Savenaca Rawaca and Josaia Wini then getting in the act.

New Zealand, who lost in the quarter-finals to England, ended up winning the plate as they saw off South Africa 26-14 in that specific final. Kenya ended up taking the bowl thanks to a 26-12 win over Argentina and Japan took the Shield final as the beat France 21-19.
