Hamburg, Germany (Sports Network) - Top seed Nicolas Almagro and third-seeded Juan Monaco highlighted Thursday's second-round winners at the $1.1 million German Tennis Championships.

The Spanish Almagro handled Russian Nikolay Davydenko 6-4, 6-3, while the Argentine Monaco topped Spanish qualifier Daniel Munoz-De La Nava 7-6 (7-4), 6-3 on the red clay at Rothenbaum Tennis Arena. The fading former top-five star Davydenko titled here three years ago.

Almagro, who was last week's runner-up in Bastad, was last year's Hamburg runner-up to France's Gilles Simon. Monaco was also a finalist last week, in Stuttgart here in Germany.

Up next for Almagro will be sixth-seeded German Philipp Kohlschreiber, while Monaco will take on France's Jeremy Chardy in Friday's quarterfinals. Kohlschreiber bested Italian Fabio Fognini 7-5, 6-2, while Chardy dismissed German wild card Julian Reister 7-5, 6-4.

The other quarterfinals will pit fourth-seeded Croat Marin Cilic against Spaniard Albert Ramos and seventh-seeded Florian Mayer versus fellow German Tommy Haas. Cilic is fresh off his clay-court title in Umag in his native Croatia last week. The 34-year-old Haas stunned the tennis world by beating Wimbledon champion Roger Federer in a title match in Halle here in Germany last month. The sweet-swinging former world No. 2 has won eight of his last 10 matches on tour.

The 2012 Hamburg champion will collect $265,000.
