The Frenchwoman, who won Wimbledon just seven weeks ago and ranked seventh in the world, dropped the bombshell after the 3-6, 6-4, 6-1 loss.
The announcement comes two weeks before she was due to compete in the US Open on August 26th.
“I’ve had a lot of injuries since the beginning of the year. I’ve been in the game for so long, and I really forced myself and gave it my all at Wimbledon,” she said at a press conference.
“I feel felt like I had lost all the remaining energy in my body. I achieved my dream and that will stay with me forever, but now my body can’t take it anymore.”
