No. 6 Barbora Zahlavova Strycova of the Czech Republic beat Croatia's Mirjana Lucic 2-6, 6-1, 6-3, but it was a bad day for second-seeded Lucie Safarova, who was upset by fellow Czech player Andrea Hlavackova 7-6 (1), 7-5.
Safarova then lost in doubles as she and Michaella Krajicek were eliminated by Heather Watson and Kathrin Woerle 6-3, 7-6 (3).
