WIMBLEDON, England -- Mike and Bob Bryan are assured of at least a silver medal at the Olympics.

The top-seeded American pair defeated Julien Benneteau and Richard Gasquet of France 6-4, 6-4 in the semifinals of the men's doubles at Wimbledon on Friday.

"We're leaving the Olympics with a medal, which is awesome," said Mike Bryan, who won bronze with his twin brother in Beijing in 2008. "To play for a gold medal, it's special. It's going to be fun. We're going to go out there and give it everything we've got."

On Saturday, the Bryans play the winner of the other semifinal between David Ferrer and Feliciano Lopez of Spain and Michael Llodra and Jo-Wilfried Tsonga of France.

"Tomorrow's going to be pretty insane," Bob Bryan said. "It could be our last shot at Olympic glory. I'm very happy that we do have a medal because semifinals is no guarantee that you're leaving with the hardware."

The pair have 11 Grand Slam titles, but rate an Olympic medal as the ultimate achievement.

"Every sports fan in the world knows what an Olympic medal is," Bob Bryan said. "Not necessarily do they know what a Wimbledon title is. I think that would be the front of the trophy case for sure."

The 34-year-old Bryans said they have talked about extending their career until the 2016 Rio de Janeiro Olympics.
