Roger Federer is the number one ranked man in tennis. He is coming off winning a silver medal in the London Olympics after losing to Andy Murray. Federer is looking to win his second grand slam of the year at the US Open this year, to add to his win at Wimbledon earlier this year. A win at the US Open would be Federer’s sixth, and his first since 2008. The 31 year old from Wollerau Switzerland in arguable the greatest men’s tennis player in history. He looks to further cement that by winning his 18th grand slam at the U.S. Open.
