New York :Victoria Azarenka collapsed and had to be taken off the court in a wheelchair half an hour into her second-round match against Gisela Dulko at the U.S. Open.
It was 90 degrees (32 Celsius) with 42 percent humidity when the 10th-seeded Azarenka took to the court Wednesday morning for a second straight steamy day of play at Flushing Meadows.
Azarenka was trailing 5-1 in the first set and not moving well when she fell to the ground, not appearing to twist or strain anything.
Medical personnel rushed out and yelled to the sideline to bring water. After a few minutes on the ground, Azarenka was helped into the wheelchair and moved off the court, with a trainer placing his hand on her neck to check her pulse.
There was no immediate update on her condition.
