Great Britain's Andy Murray defeated Switzerland's Roger Federer in the final, 6–2, 6–1, 6–4 to win the gold medal in men's singles tennis at the 2012 Summer Olympics. The final was a rematch of the Wimbledon final played at the same venue four weeks prior, in which Federer prevailed. Federer was attempting to become the third man to complete the career Golden Slam in singles. It was Federer's third consecutive Olympics as the singles world No. 1, but his silver finish remains his only Olympic medal in singles. In the bronze medal match, Argentina's Juan Martín del Potro defeated Serbia's Novak Djokovic, 7–5, 6–4. Murray's gold was Great Britain's first medal at the event since 1908, and the nation's record fourth overall. Federer's silver was Switzerland's first medal at the event since 1992. Del Potro's bronze was Argentina's first medal at the event overall.
