Tennis player Monica Puig is one victory away from Puerto Rico's first gold medal in Olympic history.
Puig continued her surprising run at the Rio Games by reaching the women's singles final, eliminating two-time Wimbledon champion Petra Kvitova of the Czech Republic 6-4, 1-6, 6-3 on Friday.
Puig is ranked 34th and unseeded, but her win over No. 11 seed Kvitova follows victories against No. 3 Garbine Mguruza and No. 14 Anastasia Pavlyuchenkova.
Puig is guaranteed to leave Brazil with no worse than a silver. She faces Angelique Kerber of Germany or Madison Keys of the U.S. in Saturday's final.
Puerto Rico has won two silvers and six bronzes at past Olympics.
Kvitova will meet the loser of Kerber vs. Keys to decide the bronze.
