United States have claimed their first tournament win of the 2018/19 series after thumping Samoa 27-0 in the final to win the Las Vegas 7s on Monday morning (AEDT).

After finishing runners-up in the four previous tournaments, the defending champions made it back-to-back titles and moved to the top of the standings with four more tournaments to play out.

After breezing through pool play unbeaten, Australia title hopes were ended by Samoa in the quarter-finals before England claimed their fifth-place semi-final 33-14 on Monday (AEDT).

Australia led 14-7 with two minutes remaining in the first half after Henry Hutchinson iced a break by Simon Kennewell, but England then piled on 26 unanswered points to advance to the fifth-place final with Fiji.

Will Edwards levelled the scores on half-time before a Will Muir double secured the win.

Muir nailed his second with a 60-metre break, capitalising on Australia playing a man down after Jesse Parahi was yellow carded for a dangerous tackle.

Ryan Olowofela completed the rout when he scythed past Ben O'Donnell to notch England's fifth try.

Australia were edged 21-20 by Samoa on Sunday, who advanced to the Cup final by beating Argentina 33-19.
