Women's second-round play began Friday with the seeded players playing for the first time. Third-seeded Victoria Azarenka was the highest seeded player to lose, falling to American Lauren Davis, 6-0, 7-6 (1), despite leading 3-0 in the second set.
Azarenka was playing for the first time since suffering a foot injury in the Australian Open in January and the injury flared up again early in the match.
"I wanted to give my best shot," Azarenka said. "I think it's pretty good considering what I have been through. I just tried to fight."
The victory was Davis' first over a Top 10 opponent after four losses.
"It means so much to me," said Davis, who is 66th on the Women's Tennis Association rankings. "My first Top 10 win and just being in the third round of Indian Wells really boosts my confidence.
"(The crowd) was awesome, really, really supportive. I think that really helped me a lot."
Second-seeded Agnieszka Radwanska of Poland was the highest seeded player to play Friday, defeating qualifier Heather Watson of Great Britain, 6- 4, 6-3, on the Stadium 1 court.
"I'm just very happy I could play quite well today and win in two sets," said Radwanska, who won the final two games of the first set and first two of the second.
"Today was very windy and we were both struggling with the serve, so I'm happy I could make it through today.
This was the third time Radwanska has faced Watson and the third time Radwanska won in straight sets.
Three other Americans also played Friday, with Varvara Lepchenko the lone winner, defeating 29th-seeded Daniela Hantuchova of Slovakia, 6-3, 6-2.
