Roger Federer and both Williams sisters have been knocked out of the Olympics. Federer was upset by American James Blake, while Venus Williams was stunned by Li Na of China and sister Serena was eliminated by Elena Dementieva. So which do you think was the biggest upset? As stunning as Blake earning his first win over Federer was, I've got to go with Venus. Who the heck is Li Na???

Federer.
Funny, this happens often in the Olympics with professional players - they rule the pro world and then they come into this competition and they tank-just witness Team canada's hockey loss last games. Mind you, Nadal is still hot.
The Olympics is a whole different arena.
