Roger Federer’s frustrating 2013 season continued in Hamburg, losing to Argentine qualifier Frederico Delbonis 7-6 (9-7), 7-6 (7-4) on clay in the semi-finals of the German Tennis Championship.

Having recently been ranked 5th, the 17-time Grand Slam champion have been trying out a larger, more powerful racquet frame, however, the 114th seed left-hander outplayed him to advanced to his first career final.

Delbonis will play Fabio Fognini of Italy, who beat Nicolas Almagro of Spain 6-4, 7-6 (7-1) to edge closer to his second title in two weeks after victory in Stuttgart.

Federer will return to action at the Swiss Open in Gsaat next week, where Rafael Nadal has also been scheduled to play.
