RIO DE JANEIRO — Rafael Nadal added a second Olympic tennis gold medal to all those Grand Slam trophies, teaming with Marc Lopez to win the men's doubles championship for Spain in the final Friday.
Nadal and Lopez beat Florin Mergea and Horia Tecau of Romania 6-2, 3-6, 6-4. Nadal, a 14-time major champion, also won an Olympic title in singles at the 2008 Games. This is the first medal for Lopez.
The bronze went to Americans Steve Johnson and Jack Sock, who beat Canada's Daniel Nestor and Vasek Pospisil 6-2, 6-4.
Nadal also advanced to the singles semifinals to face Juan Martin del Potro. Johnson was ousted by 2012 gold medalist Andy Murray, who meets Kei Nishikori.
American Madison Keys lost in the women's singles semifinals to Germany's Angelique Kerber 6-3, 7-5.
"She stepped up her game every time I had an opportunity," said the seventh-seeded Keys, 21, who faces two-time Wimbledon champion Petra Kvitova today for bronze.
Puerto Rico's Monica Puig, ranked 34th in the world, faces Kerber in Sunday's final after her back-and-forth 6-4, 1-6, 6-3 victory over Kvitova.
Puig, 22, can become Puerto Rico's first gold medalist in any sport.
Beach volleyball: Americans Kerri Walsh Jennings and April Ross advanced to the women's quarterfinals with a 21-10, 21-16 win over Italy's Marta Menegatti and Laura Giombini.
