Hamburg, Germany (SportsNetwork.com) - David Ferrer of Spain and Germany's Philipp Kohlschreiber were among the third-round winners Thursday at the Bet- at-Home Open.
The top-seeded Ferrer was pushed to three sets for the second time in as many matches this week, coming away with a 6-3, 3-6, 6-3 victory over Italy's Andreas Seppi on Thursday. He also needed three sets to dispose of Kazakhstan's Mikhail Kukushkin in the second round on Tuesday.
Ferrer beat Seppi for the eighth straight time and will next face fellow Spaniard Pablo Andujar, a 6-1, 6-2 winner over Germany's Dustin Brown on Thursday.
The seventh-seeded Kohlschreiber battled past 12th-seeded Frenchman Gilles Simon, 7-5, 6-3. Simon, the 2011 Hamburg champion, was playing his first match of the week after receiving a first-round bye and a second-round walkover.
Kohlschreiber is trying for his second win on native soil this year, having won in Dusseldorf back in May. Four of his five titles have come in Germany.
Next up for Kohlschreiber will be Lukas Rosol. The Czech saved all seven break points he faced in a 7-5, 7-6 (8-6) upset of third-seeded Spaniard Tommy Robredo, who won the Hamburg crown back in 2006.
A pair of German wild cards from Hamburg produced upsets Thursday, as Tobias Kamke took out fourth-seeded Ukrainian Alexandr Dolgopolov in a 7-5, 2-6, 7-5 decision and 17-year-old Alexander Zverev knocked out 11th-seeded Santiago Giraldo of Colombia, 6-4, 7-6 (8-6). Zverev, ranked 285th in the world, will meet Kamke in the quarterfinals.
Argentina's Leonardo Mayer thumped Dominic Thiem of Austria, 6-3, 6-2, and will meet Serbia's Dusan Lajovic in the quarterfinals. Lajovic held a 3-1 edge in the first set against countrymate Filip Krajinovic when the qualifier was forced to retire with an illness.
