Indian Wells, California - Novak Djokovic insisted Friday that he has nothing to prove beyond trying to play his best tennis as he defends his title at the Indian Wells Masters.
Ranked third behind Rafael Nadal and Roger Federer, the Serb opens play after a bye as the month-long US spring hard-court season begins in the California desert.
"I'm not trying to defend anything," said the 2008 Australian Open champion, who lifted the Dubai trophy late last month. "I'm always trying to improve, so I don't pay too much attention to the rankings."
