Roger Federer cruises into German Open quarters
Tommy Haas, Juan Monaco also advance
Top-seeded Roger Federer cruised past Czech qualifier Jan Hajek 6-4, 6-3 to reach the German Tennis Championships quarterfinals 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 with a flick of the wrist while stepping back.
The 17-time Grand Slam champion needed five set points to end the first set, finally earning it when Hajek netted a forehand.
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.
Second-seeded Tommy Haas also advanced by beating Carlos Berlocq of Argentina 6-2, 6-4.
The German led 5-2 in the second set but dropped serve. He then wasted two match points on Berlocq's serve before using his fourth to close out the second-round encounter, hitting a cross-court forehand winner. Berlocq won his maiden title in Bastad, Sweden, last week.
Juan Monaco, the fifth-seeded Argentine who beat Haas for the Hamburg title last year, defeated Benoit Paire of France 6-3, 2-6, 6-2.
Haas next plays Fabio Fognini of Italy, who beat Marcel Granollers of Spain 6-2, 6-4. Fognini won his first title last week in Stuttgart and beat Haas in the quarterfinals.
Monaco plays third-seeded Nicolas Almagro, who beat Guillermo Garcia-Lopez 6-2, 6-3.
Fourth-seeded Wimbledon semifinalist 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.
