The winner is forced to quit: "My body has had enough"

Monica Puig made history when she took Puerto Rico's first Olympic gold of all time after defeating German Angelique Kerber 2-1 in sets in the 2016 Olympic final in Rio de Janeiro.

Now she is forced to retire after a few injured seasons.

- The decision has not been easy to make because I wanted to quit on my own terms, Puig writes on Instagram.
