Anna Chakvetadze was out before she hit the ground.
In a frightening scene in Dubai, the Russian player crumpled to the court during her match against world No. 1 Caroline Wozniacki. She lay motionless for an instant before doctors and trainers attended to her, propped her up and checked her vital signs.
The 23-year-old rested for a few minutes before returning to play one point. She wisely retired before the next one.
Later, she was diagnosed with a gastrointestinal illness.
Chakvetadze had dropped the first set to Wozniacki but led 5-3 in the second when she collapsed. She appeared woozy for much of her win on Tuesday against Daniela Hantuchova and throughout the first two sets against Wozniacki.
It's hard to believe that medical officials at the tournament let her continue following her fainting spell. You can't blame the 51st-ranked Chakvetadze for trying. That's her job. It's the doctor's job to tell her she shouldn't.
With a win in her next match, Wozniacki will regain the No. 1 ranking she lost to Kim Clijsters this week.
