Britain’s Andy Murray became the first tennis player to win two Olympic singles titles by beating Argentina’s Juan Martin del Potro in Rio.
An emotional Murray, 29, secured a thrilling 7-5 4-6 6-2 7-5 victory to make it GB’s most successful day at an overseas Games with five gold medals.
The see-saw match featured 14 breaks of serve in front of a raucous crowd.
Murray’s win comes five weeks after he claimed his second Wimbledon title and four years after London 2012 success.
Both men looked exhausted in the fourth set of a gruelling four-hour contest, and Murray broke down in tears when he finished off a gritty and determined Del Potro.
The crowd on Centre Court were boisterous throughout, with plenty of Argentine support for Del Potro, although emotions did spill over near the climax when two fans were ejected.
Murray said the final was one of the toughest he had played in, and cast doubt on the possibility of him winning a third gold in Tokyo in four years’ time.
“The fact it’s not been done before shows it’s very hard so I’m proud to have done that,” he said of retaining the title.
“Four years is a long time and so many things can change. A lot has changed since 2012, I’m happy here competing for the biggest events.
“Who knows about Tokyo in four years. At 33, I’m not sure I’ll be at the same level.”
