In the men's singles, British flagbearer Andy Murray was the defending champion from the London tournament at Wimbledon, while Novak Djokovic was the number one seed and aiming to complete the Career Golden Slam. However, he was defeated in the first round by Argentina's Juan Martín del Potro. Murray defended his title, defeating del Potro in the final, 7–5, 4–6, 6–2, 7–5. With the victory, Murray became the first player, male or female, to win singles gold at two consecutive Olympics and the first player to defend an Olympic title since Serena and Venus Willams won the women's doubles title in Beijing and London. This, combined with a second Wimbledon title, becoming the first-ever three-time BBC Sports Personality of the Year and ending the year as the #1-ranked player by the ATP after having led Great Britain to their first Davis Cup since 1936 in 2015, contributed to his being knighted in the New Year's Honours List.
