In preparation for the 2012 Olympic Games in London, we're profiling 20 of the top medal contenders.

Andy Murray captivated a nation by snapping Britain’s 74-year drought for a men’s Wimbledon finalist. The fourth-ranked Scot will try to end another streak as he tries to become the first British man in 104 years to capture an Olympic singles medal.

Neil Broad and Tim Henman won the silver medal in doubles at the 1996 Atlanta Games, but the last time a British man won a singles medal was, fittingly, at the 1908 London Games, when the nation won two of the three medals.

Murray’s last Olympic appearance was brief: He was upset by 77th-ranked Yen-Hsun Lu in the 2008 Games in a loss he says was both painful and educational.

“I think maybe 10 years ago a Grand Slam was probably viewed as being bigger in tennis. But now all the top players are playing the Olympic Games,” Murray said. “So I think winning a medal for your country is a big achievement.”
