His performance was a stark reminder that he's still one of the world's best on grass surfaces and a threat to win this year's Wimbledon.
Federer was upset by Jo-Wilfried Tsonga, who won in straight sets in the men's quarterfinals at Roland Garros. He almost didn't even make it out of the fourth round in the French Open, as Gilles Simon took him to five sets.
The former No. 1 player in the world looked a bit slow and stiff on the red clay at Roland Garros, causing many to wonder how much longer he'll be able to contend at the highest level on the ATP Tour.
After his work in Germany this past week, we can be sure it'll be a while longer before Federer becomes a has-been on tour—especially on grass.
Federer blasted through his first two opponents in straight sets, losing just six games in the process. He absolutely owned Mischa Zverev in the fourth round, winning 6-0, 6-0, but his final two matches would prove to be more difficult.
Local hero, Germany's Tommy Haas, took him to three sets in the semifinals, as did Mikhail Youzhny in the final. Youzhny stole the first set before Federer finally woke up and handily won the second two, with the final tally looking like this: 6-7(5), 6-3, 6-4.
Both Haas and Youzhny had Federer on the ropes, but the legendary competitor was too sharp in the end.
Federer owns a .873 career winning percentage on grass, winning multiple tournaments and seven Wimbledon titles.
He's much better on grass than he is on clay, and it shouldn't be a surprise that he finally claimed his first victory of the 2013 season during the first grass tournament of the season.
Make no mistake about it: Despite his struggles thus far in 2013, Federer will be a force to be reckoned with in England later this month, where he'll be one of the heavy favorites to win the Wimbledon title—his second in as many years.
