Paris, France - Mallory Swanson scored the winning goal as the US edged Brazil 1-0 in the Olympic women's soccer final on Saturday to claim the gold medal for a record-extending fifth time.

Brazil fought hard on a hot afternoon at the Parc des Princes, but the USA struck just before the hour mark when Swanson – on her 100th cap – ran through to finish past goalkeeper Lorena.

It is the first time the Americans have taken the Olympic title in 12 years, their gold in Paris adding to those won in 1996, 2004, 2008, and 2012.

"I am just in awe of how hard everyone has worked to get here," said the winger Trinity Rodman.

"I believed the entire time, but to finally be able to hold (the gold medal) is so amazing."

The USA has now beaten Brazil in three of those Olympic finals, with the South Americans again having to settle for silver here, just as they did in Athens in 2004 and Beijing four years later.

It was not quite the ending that legendary captain Marta was hoping for, as she bowed out of her sixth and last Olympics aged 38 with a third silver medal.

"We surpassed ourselves throughout the competition to get to the final. That was our main objective, to come away with a medal," Marta said.

Brazil were never expected to get this far, while the USA's victory confirms their renaissance under new English coach Emma Hayes.

She only arrived from Chelsea in late May but has worked wonders with a team that a year ago was sent packing from the World Cup in the last 16.

"I am very emotional. It has been a dream of mine to be in this position," Hayes told broadcaster Eurosport.

She described her team as "tremendous people and players and role models, I love them."

The USA beat Japan and Germany in the knockout rounds to get to the Olympic final.

Brazil, meanwhile, scraped through their group as one of the best third-placed teams, before wins against hosts France in the quarter-finals and World Cup holders Spain in the last four, both achieved without Marta.

Brazil's direct approach posed problems to the USA defense in the first half and actually had the ball in the net on 16 minutes.

Ludmila turned Naomi Girma inside out in the box before finishing, but the goal was disallowed for offside.

Swanson was denied at the other end by Lorena after bursting into the box, yet it was Brazil who had the best chance of the opening half.

Captain Adriana crossed in stoppage time for Gabi Portilho to divert the ball towards goal, but Alyssa Naeher saved well.

The Americans boasted the more dangerous attack, though, and they went ahead on 57 minutes when Korbin Albert released Swanson to advance and finish expertly for her fourth goal of the tournament.

Brazil sent on Marta for the final half hour, but it never seriously looked like equalizing.

The veteran sent a free-kick over the bar, before Naeher kept out Adriana's header in stoppage time as the USA secured a third straight 1-0 win to take the title.
