Osaka had just rallied from losing the first set with a 6-1 victory in the second set to force a decisive third. Kenin took a 1-0 lead in the third when Osaka, who was reportedly flexing her left leg throughout the match, sat down to change her shoes.
Heavy tape on Osaka’s knee
With the second game of the set tied at 40-40, Osaka stopped play to receive treatment on her left knee, which trainers taped up.
U.S. Open status unclear
After several minutes, Osaka returned to finish the game that Kenin won before deciding to retire from the match.
The nature of Osaka’s injury is unclear, as is how it will affect her status for the upcoming U.S. Open.
Osaka said after the match that she’s never felt pain that before and that she hasn’t yet received a medical explanation. She’s hopeful of playing in the U.S. Open.
"Last year I won the U.S. Open, and this year I'm trying to play the U.S. Open."
