Katerina Siniakova stormed to a 6-0 6-2 win against Donna Vekic, while Lesia Tsurenko eliminated Christina McHale in straight sets and will take on another American, CoCo Vandeweghe next.
At the Luxembourg Open, Anett Kontaveit, seeded third, eased past Jana Cepelova 6-0 6-2, and there were also wins for Elise Mertens, Beatriz Haddad Maia, Madison Brengle and Carina Witthoft.
