Andy Murray narrowly failed to make it a golden double as he and Laura Robson were beaten by Max Mirnyi and Victoria Azarenka of Belarus in the Olympic final of the mixed tennis doubles.
Murray returned to Centre Court only 45 minutes after thrashing Roger Federer to win singles gold, and it looked like he would be celebrating again when the British pair raced through the first set.
But Mirnyi and Azarenka, the women's world number one, hit back to take the second and it was the Belarussians who prevailed in a close match tie-break to win 2-6 6-3 10-8.
"I'd like to thank Andy for playing with me. It's been one of the best weeks of my life, for sure," Robson told BBC1.
"They're top seeds for a reason. I was just happy to be in the final, but it's definitely tough to lose."
Murray added: "We would have signed up for that at the start of the event. It's just annoying to lose. We were so close and played so well in the first set."
