Brazil needed every second of a tense final against Argentina to successfully defend the Sudamericano Femenino de Sevens title at the Carrasco Polo Club in Montevideo on Saturday.

Argentina looked set to force the 13-time champions into extra-time, until Thalia da Silva Costa took the ball after a series of passes to first fend off and then outrun the Las Pumas defence to touch down. The try was converted and with time up Las Yaras were able to celebrate having preserved their record of winning all 14 Sudamericano Femenino de Sevens tournaments they have entered since it began in 2004.

It was the 11th time that Argentina have lost to Brazil in the final, although there was some consolation in that they will join their conquerors in the World Rugby Sevens Series 2020 qualifier in Hong Kong next April and the Pan American Games in Lima, Peru, next July.

Brazil, though, as champions will be the invitational team for the HSBC Canada Women's Sevens in Langford in May.

Las Yaras were comfortable winners against every team bar Argentina, with only Peru managing to score tries against them, on both the opening day and in the semi-final. Brazil beat Costa Rica 47-0, Peru 38-7 and Colombia 40-0 in the pool stages on Friday, Uruguay 31-0 in the quarter-final and again outscored the Peruvians 31-5 in the semi-final.

Argentina scored two tries and were at one stage leading in the final, but it wasn't enough to win their first title. Colombia claimed the bronze medal after beating Peru with the rankings completed by Chile, Paraguay, Uruguay and Costa Rica.
