INDIAN WELLS, Calif -- Americans Madison Brengle, Louisa Chirico, and Kayla Day moved to the second round at BNP Paribas Open on Wednesday.
Chirico defeated 2010 French Open champ Francesca Schiavone in two sets 6-3, 6-3. Teenager Day beat Kurumi Nara 6-3, 6-4.
Brengle passed past her good friend Tatjana Maria in straight sets 6-4, 6-2.
"It's really difficult to play your friends for sure," said Brengle. "The ball can fly a little bit hear so sometimes if I struck the ball a little around sometimes I felt it could fly on me. And the way she plays the slice is a little tricky and so sometimes having to generate your own pace.
"I tried to use a lot of the court so whenever I can attack with my backhand I then tried to move her around opening up the court with my forehand," said the 26-year-old.
Despite spending much of her off-season relearning how to serve due to nerve damage, Brengle was able to pull out an extraordinary upset in the beginning of the year as she beat Serena Williams in the second round of ASB Classics in Auckland.
"It was a little surreal when it happened. I definitely did not see that coming but it was exciting. "But I had to go out the next day and play but it was difficult to sleep the night before because there's so much emotions going on.
"So I felt like I got to enjoy it for about half a day and then you're onto the next match and I lost. It was cool it's something that I kind of keep in my pocket for my entire career and something I can tell my grand kids."
