Top seed David Ferrer had to dig deep to reach the quarter-finals at the ATP Portugal Open on Wednesday finally overcoming Frenchman Eduardo Roger-Vasselin 6-4 4-6 6-3.
The 31-year-old Spaniard, who was beaten in his opening match at last week’s Barcelona Open, will play Romanian journeyman Victor Hanescu, who accounted for sixth-seeded Frenchman Benoit Paire 7-6 (7-2) 6-4.
Ferrer, who missed the Monte Carlo Masters after injuring a thigh in the final of the Miami tournament in March, is looking to get some valuable court time prior to the French Open later this month.
The Spaniard had looked to be crusing to victory when he led by a set and 4-2 in the second but then lost his concentration.
“I lost that game and the set. In the third it was tough to break him,” he said.
“It was a very good match to get through but I certainly have to lift my level for the next round. Hanescu is a good player even if I’ve beaten him before. I have to play well.”
In the women’s draw, two-time grand slam winner Svetlana Kuznetsova reached her first quarter-final since the Australian Open when she beat Kazakh Galina Voskoboeva 6-4 6-4.
Kuznetsova, ranked 45 in the world and a wild card entry, said that while she was happy to win, she was not particularly impressed with how she got through over her rival, who is ranked 117th.
She will play Romina Oprandi, who beat China’s Peng Shuai 6-1 6-3, in the quarter-finals.
Three of the four seeds in the women’s singles advanced to the quarter-finals, led by number three Anastasia Pavlyuchenkova, coached part-time by former great Martina Hingis.
The Russian beat Spain’s Estrella Cabeza Candela 6-3 7-6 (7-4).
Fourth-seed Carla Suarez Navarro came good for Spain, beating former Portugal Open winner Yanina Wickmayer of Belgium 6-4 6-3 while Estonia’s defending champion Kaia Kanepi upset Romanian fifth seed Sorona Cirstea 6-1 6-2.
Monica Puig of Puerto Rico ended the 2010 French Open champion Francesca Schiavone’s hopes of a second successful title, after winning in Marrakech last Sunday, as she beat the Italian 6-3 6-2.
