ROTTERDAM, Netherlands (AP) -- Second-seeded Tomas Berdych advanced to the quarterfinals of the ABN Amro World Tennis Tournament on Thursday when Marcos Baghdatis retired with a leg injury in the fourth game.
Baghdatis injured his left calf in the opening set when Berdych took a 3-0 lead.
A trainer wrapped Baghdatis' calf and he returned to the court. But the Cypriot looked hobbled by the injury and gave up a few points later.
In other matches, fifth-seeded Richard Gasquet beat Alex Bogomolov Jr. 6-3, 6-2, and Andreas Seppi defeated Philipp Kohlschreiber 6-4, 6-2.
