Serena Williams loses to Jankovic

Jankovic has been playing in rising through the rankings, she has never reached the final of a Grand Slam, while Williams seemed to be close to the form that she once used to dominate women's tennis.Suddenly, stunningly, gone were Williams' chances of defending her title. Gone were images of her spryly sprinting on the court in her first four matches, clearly leaner and fitter than last year, raising questions whether anyone could beat her.Instead, the last memories will be of Williams struggling, smashing her racket - bashing it twice when, like on so many points this day, she just didn't put enough power to finish it off the first time.
