Even the best players in the world have at least one loss that haunts them, one they will never forget.
A number of today's stars suffered humbling losses in the 2013 Wimbledon tournament. It makes you wonder whether any of those defeats ranks as the toughest loss in that player's career.
We chose 10 current tennis stars and attempted to pinpoint the one loss that would be the most difficult to erase from their memory. It could have been the magnitude of the upset that makes it unforgettable, or it could have been other circumstances that keep the loss in mind.
The five men selected are the top five ranked male players. That includes the so-called Big Four of Roger Federer, Rafael Nadal, Andy Murray and Novak Djokovic, as well as No. 3-ranked David Ferrer, the only player outside the Big Four to reach the finals of one of the past 12 Grand Slam events.
Four of the five women chosen are the top four ranked players: Serena Williams, Maria Sharapova, Victoria Azarenka and Agnieszka Radwanska. The fifth is Venus Williams, whose ranking has slipped into the 30s because of health issues, but who remains a star and hopes to play in the upcoming U.S. Open.
