Last year's winner Milos Raonic was able to confidently defend his title. He won the final against the German Tommy Haas in straight sets 6: 4 and 6: 3. He didn't give up a set during the whole tournament and only had to tie-break once against Denis Istomin . In doubles, Scott Lipsky and Rajeev Ram were the defending champions, but they no longer played together this year. While Ram did not take part in the tournament, Lipsky played with Santiago González and was eliminated in the quarterfinals. Xavier Malisse and Frank Moser won the final against Lleyton Hewitt and Marinko Matosevic in three sets; for Moser it was the first title on the ATP World Tour.
