Serena crashes, Djokovic cruises at French Open

Defending champion and world number one Serena Williams was knocked out of the French Open by Spain's Garbine Muguruza on Wednesday as the American star stumbled to her second worst Grand Slam defeat.
      
The top seed lost 6-2, 6-2 in the second round to the world number 35 with her defeat coming just an hour after sister Venus also went out, 2-6, 6-3, 6-4 to Slovak teenager Anna Schmiedlova.
      
It was the earliest exit for a defending champion at Roland Garros since 2005 when Anastasia Myskina of Russia went out in the first round.
      
With Li Na losing in the first round on Tuesday, Serena's defeat marks the first time in the Open Era that the top two seeds had failed to get to the third round at a major.
      
Wednesday's defeat was Serena's worst at a Grand Slam in terms of games won and was only the second time she had been beaten at a major in the round of 64.
      
The last time that happened was on her debut at the 1998 Australian Open.
      
"Nothing worked today," said 17-time major winner Serena who hit just eight winners and a huge 29 unforced errors with five double faults.
      
"I just couldn't serve. But you can't be on form every day. I hate to be off at a Grand Slam but it happens, it's not the end of the world.
      
"I will have to work five times as hard to make sure it doesn't happen again," added the 32-year-old American who suffered her only Grand Slam first round loss in Paris in 2012.
      
Muguruza, 20, immediately won praise for her performance.
      
"Shocker at the French - Serena loses to Garbine Muguruza. Garbine is here to stay, that's for sure...
