Summary Victoria Azarenka and Agnieszka Radwanska cruised into third round of the Qatar Open.
Fresh off winning a second consecutive Australian Open, top-ranked Victoria Azarenka breezed into the third round of the Qatar Open with a 6-2, 6-3 victory over Romina Oprandi on Wednesday.
The defending champion was joined by fourth-ranked Agnieszka Radwanska and former No. 1 Caroline Wozniacki. Radwanska beat Australian qualifier Anastasia Rodionova 6-3, 6-2, and Wozniacki downed Sorana Cirstea of Romania 7-6 (7), 6-0.
American Sloane Stephens, who upset Serena Williams in the Australian Open quarterfinals, lost to Klara Zakopalova 4-6, 7-6 (5), 7-6 (5).
Stephens pulled out of Fed Cup against Italy last week after aggravating an abdominal muscle injury and suffering from a stomach virus.
Azarenka will retain her top ranking if she reaches the final and Williams fails to reach the semifinals. She made a nervous start, dropping serve to fall 2-0 behind. But the Belarusian recovered to break three times and win the first set.
Azarenka then took a 3-0 lead in the second set.
Radwanska had little trouble with the 131st-ranked Rodionova, breaking to go up 3-1 on the way to winning the first set.
The second set was even more one-sided, with the Pole breaking twice on the way to victory in which she said "the wind changed every couple of minutes. It was very tricky.
Radwanska has started the season well, winning in Sydney and Auckland and reaching the quarterfinals of the Australian Open. Having reached the Wimbledon final last year, she feels ready to challenge for the No. 1 ranking.
Several seeded players lost, including the 16th-seeded Stephens. Marion Bartoli, seeded ninth, lost to Svetlana Kuznetsova 6-4, 6-4, while No. 17 Lucie Safarova of the Czech Republic was beaten 6-4, 6-2 by Christina McHale of the United States. Urszula Radwanska, the sister of Agnieszka, upset 15th-seeded Roberta Vinci of Italy 6-2, 5-7, 6-0.
Wozniacki saved four set points in the tiebreaker before going up 1-0 when Cirstea hit a crosscourt backhand wide. The second set was a procession with the Dane breaking three times.
