Top-seed Daniela Hantuchova advanced seeded former runner-up Lucie Safarova came up a second-round loser Thursday at the $220,000 Bell Challenge.

Hantuchova, of Slovakia, earned a 6-7 (4-7), 6-4, 6-3 victory over Hungary's Melinda Czink.

The 2009 Quebec City finalist Safarova gave way to fellow Czech Andrea Hlavackova in 7-6 (7-1), 7-5 fashion on the indoor hardcourts at PEPS Laval University Campus.

Safarova lost to Czink in the finale here two years ago.

Sixth-seeded Czech Barbora Zahlavova Strycova overcame Croat Mirjana Lucic 2-6, 6-1, 6-3, while another Day-4 upset came when New Zealand's Marina Erakovic took out seventh-seeded American Irina Falconi 6-3, 2-6, 6-2.

For her feat, Erakovic garnered a date with Hantuchova.

Zahlavova Strycova will face Hlavackova in an all-Czech quarterfinal on Friday.

The 2011 Bell Challenge titlist will earn $37,000.
