Four-time champion Roger Federer, German crowd favorite Tommy Haas and last year's titlist Juan Monaco were among Wednesday's second-round winners at the $1.44 million German Open Tennis Championships.
The top-seeded former world No. 1 Federer dropped the opening set before fighting back to beat Germany's Daniel Brands 3-6, 6-3, 6-2 in 1 hour, 25 minutes on the red clay at Am Rothenbaum. Federer popped nine aces and was broken only once in advancing.
"It was a tough match. Daniel is playing a very good season," Federer said.
The 17-time Grand Slam champion dropped to No. 5 in the latest world rankings and is sporting a new racquet with a bigger frame this week.
His third-round opponent on Thursday will be Czech Jan Hajek.
Meanwhile, last year's Hamburg runner-up to the Argentine Monaco, the second- seeded Haas, held off Slovenian Blaz Kavcic 6-1, 4-6, 6-4, and a fifth-seeded Monaco doused oft-injured fellow former top-10 star Gael Monfils, of France, 6-4, 6-4 on Day 3.
Monaco's next opponent will be ninth-seeded Frenchman Benoit Paire, while Haas will encounter hot Argentine Carlos Berlocq.
In other action involving top-10 seeds, No. 4 Pole Jerzy Janowicz snuck past Dutch fellow big-server Robin Haase 6-4, 3-6, 7-6 (7-4), Spaniard Marcel Granollers upended No. 6 Italian Andreas Seppi 6-2, 1-6, 6-1, and Argentine qualifier Federico Delbonis took down No. 10 Spaniard Tommy Robredo 6-1, 4-6, 6-4. Robredo titled here back in 2006.
Also in the round of 32, 11th-seeded Spaniard Feliciano Lopez took care of German wild card Jan-Lennard Struff, 7-5, 6-3; 12th-seeded Italian Fabio Fognini drubbed Spaniard Albert Ramos 6-1, 6-3; Spain's Guillermo Garcia-Lopez knocked out 13th-seeded Russian Mikhail Youzhny 6-3, 6-7 (3-7), 6-2; 14th- seeded Spaniard Fernando Verdasco bested fellow countryman Roberto Bautista Agut 6-4, 3-6, 6-2; the qualifier Hajek drove out 15th-seeded Latvian Ernests Gulbis 6-4, 2-6, 6-4; and Berlocq toppled 16th-seeded Slovak Martin Klizan 4-6, 6-1, 7-6 (8-6). Berlocq captured his first-ever ATP title in Sweden last week by surprising Verdasco in the final. Fognini also nailed down his maiden championship in Stuttgart last week.
The 2013 Hamburg titlist will earn $328,000.
