Video: Federer and Verdasco through in Germany
Top-seeded Roger Federer cruised past Czech qualifier Jan Hajek 6-4, 6-3 to reach the German Tennis Championships quarter-finals in Hamburg on Thursday.
The four-time Hamburg champion is playing his first tournament since losing in the second round of Wimbledon.
Federer used only three of 13 break points and needed six match points to close out the match. He did it with his seventh ace, moments after producing a spectacular overhead smash winner.
Federer has dropped to No. 5, his lowest ranking in a decade. He will next play Florian Mayer of Germany, who beat 11th-seeded Feliciano Lopez of Spain 7-6 (1), 6-2.
Fourth-seed Wimbledon semi-finalist Jerzy Janowicz of Poland was forced to retire with a right arm injury, allowing Fernando Verdasco to advance.
The Spaniard, who was leading 7-5, 4-0, will next play Argentine qualifier Federico Delbonis, who beat Dmitry Tursunov of Russia 6-4, 6-3.
