Defending champion in the singles was Albert Montañés , who was eliminated in the round of 16 this year. Even before the quarter-finals, all eight seeded players were eliminated.

In the final he prevailed against his compatriot Pablo Andújar . This was Ferrero's first season and sixteenth career title. In doubles Carlos Berlocq and Eduardo Schwank were the defending champions, but they did not compete this year. This year's winners were Jürgen Melzer and Philipp Petzschner , who defeated the Spanish doubles Marcel Granollers and Marc López . The win in Stuttgart was the duo's second title of the season and their fourth joint title.
