As a result, Puig will become the first woman representing Puerto Rico to win an Olympic medal and has the chance to become the first athlete from Puerto Rico - man or woman - to win a gold medal.
#PicaPower, the world No.34's rallying cry on social media, became a worldwide trending topic on Twitter following her victory.
Entering the gold medal match, Puig has won a career-best 36 main draw matches in 2016, more than she won in the previous two seasons.
But perhaps most impressive? did Puig forecast her success in Rio back on July 27 when she shared with her Twitter following that she introduced "Rio Puig" to the Twitter-verse?
While Puig will become the first woman representing Puerto Rico to win an Olympic medal, Gigi Fernandez, born in San Juan, Puerto Rico, won two gold medals in doubles for the United States playing alongside Mary Joe Fernandez in 1992 and 1996. Gigi was quick to join in the celebration.
