Victoria Azarenka was forced to retired in her match against Gisela Dulko earlier today in her first round match at the US Open after she collapsed on court. She was later rushed off in a wheelchair.
The weather isn't that bad today with 90 degree and only 40% of humidity. So it can't be a heat stroke but from what it seems, maybe that is what she suffered.
Fans were on their feet as well as Dulko herself because they did not know what was happening to Azarenka.
“I was scared,” said Dulko, who advanced to the third round. “She went to the floor. I was worried for her. I went to see her, brought some ice, did whatever I could do to help.”
Usually the danger of the heat is when the humidity is high, but maybe with the sun shining down on the court, it was tougher than it looks.
“It’s tough to play out there,” Dulko said. “It’s really hot, really humid. You sweat so much, sometimes it’s impossible to hold the racquet.”
