"There are always things that could have been done better, but I think I had a pretty solid start," said Azarenka, who drew the short straw among the top women's seeds when she was put on a path to a possible third-round clash with Williams.
Williams is seeded just 28 here, after a rankings slide due to her nearly year-long absence with a series of health problems. Williams has nevertheless stamped herself a favorite with two hardcourt victories in the build-up to the Open, and her potential third-round clash with Azarenka was the talk of the draw last week.
Azarenka insisted she wasn't worrying about Williams just yet.
"I'm not interested about that before I go out there," she said. "We'll talk about it later maybe."
In other early matches, Spanish fifth seed David Ferrer rallied to reach the second round with a 2-6, 6-3, 6-0, 6-4 victory over Russian Igor Andreev.

Wimbledon semi-finalist Sabine Lisicki of Germany romped to a 6-3, 6-3 victory over Alona Bondarenko in just 70 minutes.
Lisicki, who arrived in New York fresh from a WTA triumph in Dallas on Saturday, booked a second-round clash with two-time US Open champion Venus Williams.
