MONTREAL (AP) - Jo-Wilfried Tsonga upset Roger Federer in the Rogers Cup on Friday, making a dramatic comeback from 5-1 down in the third set to beat the world's top-ranked player 7-6 (5), 1-6, 7-6 (3).
The Frenchman broke Federer's serve twice in front of a frenzied crowd at Uniprix Stadium. Federer hung on to force a tiebreaker, but Tsonga used two aces to take the lead and Federer double-faulted on match point.
The surprise 2008 Australian Open finalist ended Federer's 22-match winning streak and earned a spot in the semifinals against Andy Murray.
Tsonga has won two of three career meetings with Murray, who earlier advanced 6-2, 6-4 over Nikolay Davydenko.
Federer, who outlasted Andy Roddick in a marathon Wimbledon final in June, took a break while his wife gave birth to twin girls.
He looked sharp against Tsonga, the world's No. 7 player, until his first serve appeared to desert him late in the third set and he sent several groundstrokes wild.
Murray, who has yet to drop a set in the tournament, made the semis for the third time in four years.
It is Murray's third trip to the Rogers Cup semifinals. Last year in Toronto, he lost to eventual champion Rafael Nadal. He was also in the semis in 2006.
In Friday's evening matches, No. 4 seed Novak Djokovic was set to face No. 5 Roddick and No. 2 Nadal plays No. 6 Juan Martin Del Potro.
