INDIAN WELLS, Calif. (AP) -- Third-seeded Victoria Azarenka tumbled out of the BNP Paribas Open on Friday night in her first match in more than a month, falling 6-0, 7-6 (2) to American Lauren Davis.
Azarenka, from Belarus, had been sidelined since the Australian Open because of a left foot injury that required her to wear a boot for several weeks.
The two-time Australian Open champion, hampered by nerve damage between her toes, limped visibly at times, had trouble serving, fell to her knees several times, broke a racket after double-faulting to fall behind 4-3 in the second set, and fought back tears.
Most of the other second-round matches were routine. Second-seeded Agnieszka Radwanska of Poland got it started by beating qualifier Heather Watson of Britain 6-4, 6-3. Later in the day session, No. 6 Simona Halep, No. 7 Jelana Jankovic, No. 9 Sara Errani and No. 10 Caroline Wozniacki were straight-set winners.
