"The union of this group identifies us as a team," said Argentina player Ivana Eliges.

"It gives us strength.

"We have fun and know each other a lot on and off the field.

"It is our essence – that which makes us overcome every obstacle that is presented to us to move forward and achieve the objectives."

The bronze medal match saw Paraguay overcome Venezuela 14-11, 10-9.

Despite having to settle for the silver medal in the women’s event, Brazil went all the way in the men’s competition.

The reigning world champions beat Uruguay 24-14, 10-16, 6-4 in the final following an 18-10, 33-18 victory over Chile in the penultimate round.
