Angelique Kerber and Sloane Stephens reached the quarter-finals of the Linz Open in contrasting style.
Top seed Kerber crushed Romania's Alexandra Cadantu 6-1 6-0 in 50 minutes, while second seed Stephens spent more than three times as long on court in fending off German Andrea Petkovic in three sets.
World No.12 Stephens eventually prevailed 7-6 (7-1) 4-6 6-3 in two hours and 31 minutes and will take on Switzerland's Stefanie Voegele in the last eight.
Voegele was a 4-6 6-2 7-5 winner over Italy's Karin Knapp.
Patricia Mayr-Achleitner of Austria defeated Ukraine's Maryna Zanevska 6-1 6-7 (1/7) 6-4 to set up a quarter-final against world No.10 Kerber.
Earlier in the day, seventh-seeded Slovakian Dominika Cibulkova routed Katarzyna Piter of Poland 6-0 6-1 in less than 53 minutes.
Cibulkova will take on two-time former winner Ana Ivanovic in the quarter-finals.
