Rafael Nadal is out of Wimbledon.  The reigning French Open and 12-time Grand Slam champion has been upset in his first-round match by 135th-ranked Steve Darcis of Belgium.  Nadal says he's not about to blame his knee problems for this loss. 

Nadal lost 7-6, 7-6, 6-4.  He's the first defending French Open champion to lose in the first round of Wimbledon since Gustavo Kuerten in 1997.  Nadal is now 34-and-1 all-time in the first round of a major.
