The Brazilian pair, unbeaten in all six matches they played in the Florida sunshine, took home a $40,000 (£29,000/€32,500) prize after defeating qualifiers and compatriots Taiana de Souza Lima and Carolina Horta Máximo.

There was also cause for home celebration as the United States won a first bronze medal on home sand on the World Tour thanks to Brooke Sweat and Summer Ross, who earned a 21-17, 21-13 win over Germans Victoria Bieneck and Isabel Schneider.

However, the final was all about Brazil as the packed Lauderdale Beach Park Center Court crowd were treated to a beach volleyball masterclass in this five-star tournament.

Seixas, the 30-year-old 2016 Olympic silver medalilst, and Alves, 32, won in straight sets 21-16, 21-13.

It was the winners’ second title on the World Tour as a team since they joined forces after Rio 2016, and their first on the Major Series together.

"My partner was on fire and so was I," said Seixas.

"I think we learned that we should never give up and focus on every single point.

"It’s why I feel so passionate about the sport.

"It’s why I yell and scream and shout – I’m really happy."

For Lima and Horta, who was playing in her first final, their journey from the country quota ended with a silver medal in their 10th match of the tournament.

"We gave all we had left, but they played better," said the 33-year-old Lima.

"Either way, it has been an incredible week for us.

"When Carol called me and we decided to play this tournament together, we had no idea of what could happen and here we are.

"It has been special for us.

"To me, this silver is like gold - I will always have this week in my memory."

Horta, 25, who stepped in at the last minute following an injury to Elize Maia Secomandi days before the competition started, said: "I always feel disappointed when I lose, but we are happy about the second place.

"Competing for the gold medal after six days of tough matches meant a lot for us."

Ross and Sweat’s success in the bronze medal match came a year after they lost the bronze medal match in the same event.

"It means a lot to do this here in Florida," said Sweat afterwards. 

"Especially after the heart-wrenching loss in the semis."

The men’s medals are due to be contested tomorrow.
