The defending champion has already been eliminated from the French Open, as world No. 1 Serena Williams fell victim to a shocking upset on Wednesday morning. The younger Williams sister was defeated by Garbine Muguruza, the 35th-ranked player in the world, in the second round.

The 20-year-old Muguruza needed just 64 minutes to defeat Williams in straight sets. Williams won just four games, making the loss the worst of Serena’s career at a major tournament.
