LONDON -- Vasek Pospisil had a bad back. He and partner Jack Sock had never played doubles together before. And they were facing the most successful doubles tandem in Grand Slam history in Americans Bob and Mike Bryan.
The formula for the newest Wimbledon champions?
"Close your eyes," said Pospisil, "[and] hope you play the best tennis of your life."
Evidently, it worked for Sock and Pospisil, who broke the Bryans' serve in the final game and won in dramatic fashion on their fifth match point Saturday 7-6 (5), 6-7 (3), 6-4, 3-6, 7-5.
"As kids we grew up watching this tournament," Sock said. "This is what we kind of dreamed of doing. To be able to go out there and play the best doubles team of all time and to get a win was pretty incredible."
Sock, ranked 77th in singles, adds the Wimbledon doubles title to his 2011 US Open mixed title with American partner Melanie Oudin.
"He's having fun. He's winning the close matches. The singles, I think, will come for him," said Bob Bryan after his brother called Sock's forehand "one of the biggest in the game."
"He's shown that he can win a big match. He just has to string it together like he has in this tournament in doubles. He's got some artillery that's going to translate anywhere. So it's just a matter of time before he puts it together in the big moment on the singles court."
Italy's Sara Errani and Roberta Vinci became the fifth women's doubles team to complete a career Grand Slam with their first Wimbledon title Saturday after a 6-1, 6-3 victory over Timea Babos and Kristina Mladenovic.
"Unbelievable," Errani said. "No words to tell you what it is for us. ... We were thinking about [winning the Grand Slam] all day, all morning."
"I honestly can't grasp the fact that we've been able to accomplish all of this," Vinci said. "I think I'll realize it all after we finish playing. I'll say, 'Wow, we did all of that.'"
Rubin, 18, is the first U.S. champion since Donald Young in 2007. The last time two American men played in the Wimbledon final was 1999, when Pete Sampras defeated Andre Agassi, and the last All-American boys' final was in 1977, when Van Winitsky beat Eliot Teltscher.
Rubin, who trains at John McEnroe's Academy in New York, had to win two qualifying matches to get into the main draw.
"Nothing said I couldn't be here," Rubin said. "I believe in my competitiveness, my mental capability and speed. I don't see why not. But I wasn't thinking ahead to this. ... It was just point-by-point, match-by-match. Eight matches later, this is where I am."
Kozlov, 16, brought an American flag, and the two did a celebratory lap around Court 1 together.
"At the end when we were holding the American flag," Rubin said, "I was like, 'This is pretty special. Hopefully we'll keep rising together and none of us will fall off, and as a group get to the top and show the results America wants.'"
