Andy Murray of Great Britain becomes the first ever player to win two straight men’s tennis singles in the history of Olympics as his second in Rio after having won his first in London 2012.
An emotional Murray, 29, secured a thrilling 7-5 4-6 6-2 7-5 victory after beating Del Potro in men’s tennis singles in Rio on Sunday.
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, with Murray breaking down in tears after finishing off his gritty opponent.
Murray said the final was one of the toughest he had played in and cast doubt on the chances of winning a third gold in Tokyo in 2020.
Del Potro’s silver medal signifies his continued return to form, with his past three seasons disrupted by a wrist injury.
The 27-year-old beat world number one Novak Djokovic in the first round despite being stuck in a lift for 40 minutes before the match.
