Roger Federer has been holding court at the London Olympics, and he delivered up a secret: He can't play tennis "at all" with his left hand.
Other tidbits from the winner of 17 tennis majors at an entertaining news conference:
* He is not a huge autograph hunter.
* He is looking forward to chatting with other Olympians — "It doesn't matter if they are famous or not."
* And he is in two minds about being able to wear colored kit at Wimbledon, where the usual etiquette requiring that players wear white is relaxed for the Olympics.
"I feel a bit awkward playing in a red shirt out at Wimbledon," he said. "But I don't dislike it."
Federer, 31 next month, wouldn't rule out another Olympic appearance — it would be his fifth — at the Rio de Janeiro Games in 2016. "There's definitely a chance," he said.
