American Jack Sock and Canadian Vasek Pospisil upset the Bryan brothers in five long sets to win the men's doubles final at Wimbledon.
The scratch pair, who only signed up days before the draw, eventually triumphed 7-6 (7-5) 6-7 (3-7) 6-4 3-6 7-5 in just over three hours.
They are ranked 99 and 94 respectively in the world doubles rankings and claimed their first title together.
Bob and Mike Bryan, the top seeds, were seeking their 16th Grand Slam title.
Despite the disparity in rankings there was little to separate the two pairs in the opening two sets which were decided by tie-breaks.
There was just one break in the third set as Pospisil, 24, and Sock, 21, moved two sets-to-one ahead.
The Bryan brothers, seeking their 99th career title, hit back, converting one of their two break points in the next to take the match into a deciding fifth set.
But the youngsters kept their nerve to secure their first title as a pairing.
Sock, aged 21 years 285 days, is the third youngest man in the Open era to win both a Grand Slam men's doubles title and a Grand Slam mixed doubles title, having previously won the 2011 US Open mixed doubles title with fellow American Melanie Oudin.
