Top seed Caroline Wozniacki had no trouble defeating Elena Dementieva 6-1, 6-1 on the first day of play in theWTA Championships in Doha today. Dementieva, who was recently bothered by an inflamed foot, said that the heat and humidity made it difficult for her to play in Doha, and that she was "going for the wrong shots all the time." Also winning in the maroon group on day 1 was Sam Stosur, who defeated Francesca Schiavone 6-4, 6-4. Schiavone defeated Stosur on clay in the French Open final earlier this year.
In the white group, Vera Zvonareva (who is now number 2 in the world) defeated Jelena Jankovic 6-3, 6-0. Jankovic had problems with her movement--generally one of her greatest strengths--and she had repeated problems with her serve. Jankovic has been ill for several days, and she said she felt dizzy and felt some tingling during the match, and that she had difficulty breathing. These were the symptoms she experienced in Moscow last week. Jankovic received IV treatment following the match, and said that she plans to remain in the tournament.
Jankovic has a history of respiratory problems, and--though she had nasal surgery a few years ago--she continues to have problems breathing when she is active.
