HAMBURG, Germany (AP) - Top-seeded Roger Federer lost to Argentine qualifier Federico Delbonis 7-6 (7), 7-6 (4) Saturday in the semifinals of the German Tennis Championships.

Federer is a 17-time Grand Slam champion and four-time winner in Hamburg. But he was outplayed by the 114th-ranked lefthander who advanced to his first career final. Federer took a wild card for the clay-court Hamburg tournament after losing in the second round at Wimbledon.

Delbonis will play Fabio Fognini of Italy, who moved within one win of his second title in two weeks when he beat third-seeded Nicolas Almagro of Spain 6-4, 7-6 (1).

Fognini won his first career title in Stuttgart last week and is riding a nine-match winning streak.

It was the 12th-seeded Italian's 24th win on clay this season. Fognini is the second Italian to reach the final in Hamburg after Adriano Panatta lost to Manuel Orantes in 1972.

Almagro is second in career clay-court titles among active players with 12. Rafael Nadal has 42.
