The individual winner was Philipp Kohlschreiber , who beat defending champion Lleyton Hewitt in the quarter-finals. In a purely German final, he benefited from the task of Philipp Petzschner and thus won his third ATP title. It was his first triumph in Halle after losing in the same place in the final in 2008 to Roger Federer, who had to cancel his participation in 2011 due to an injury. It was also the first ATP title for a German player since Benjamin Becker's victory in 's-Hertogenbosch almost two years earlier. In doubles, Serhij Stachowskyj and Michail Juschny were unable to defend their title due to an injury to Juschny . In the final, the top seeded Rohan Bopanna and Aisam-ul-Haq Qureshi defeated the pairing Robin Haase and Milos Raonic . This was the duo's first title in Halle and their first title of the season.
