    Family and friends in Puerto Rico cheered with pride as she gave the Caribbean island its first Olympic gold medal, a major morale boost for the U.S. territory currently facing a crippling debt crisis and a serious Zika outbreak.

    "I knew from the first moment the match started getting intense that I needed to give my all and I stayed there and I stayed focused and I did exactly what I needed to do," Puig said.

    "The whole match was just unbelievable high-quality tennis and it was just the moment of my life," Puig said.
