Williams booked a second-round match against wold number 10 Victoria Azarenka of Belarus at the US Open tuneup event.

Serbian fifth seed Ana Ivanovic ousted Germany’s Sabine Lisicki 7-6 (7/2), 6-1.

Next up for Ivanovic will be Canada’s Carol Zhao, who advanced when leading 6-2, 1-0 after Belgian Yanina Wickmayer retired.

Puerto Rico’s Monica Puig eliminated seventh seed Carla Suarez Navarro of Spain 6-3, 7-5.

Also falling was sixth seed Dominika Cibulkova of Slovakia, who lost to Spain’s Garbine Muguruza 6-2, 4-6, 6-2.
