3x3 basketball in Puerto Rico

In order to promote the popularity of the sport, FIBA decided to organize tournaments based on the streetball variant of 3-on-3 in 2010, mainly due to its predominance even in countries without basketball tradition, creating a division named FIBA 3x3. Team San Juan, based on the municipality of the same name, was the champion of the first edition of the FIBA 3x3 World Tour. The Puerto Rico men's national 3x3 team has won medals in the Pan American and Central American and Caribbean Games.
