Germany’s Andrea Petkovic blew out American Jamie Loeb 6-1, 6-1, and Russia’s Svetlana Kuznetsova eased past American Kristie Ahn 6-2, 6-1.

Hungary’s Fanny Stollar defeated Japan’s Mayo Hibi 6-1, 7-6 (6). The last match of the evening was suspended due to rain with sixth-seeded Belinda Bencic of Switzerland leading Great Britain’s Harriet Dart 7-5, 4-1.
