Frenchman Jo-Wilfried Tsonga will look to avenge last week\'s Shanghai Masters quarter-final loss against Tomas Berdych in the Stockholm Open final, after beating Marcos Baghdatis 6-4, 4-6, 5-2. The top seed advanced to the final after beating 2009 champion Baghdatis, but only after the Cypriot retired due to a left groin strain. \"It was a very good match, so I\'m sad it ended like this,\" Tsonga told Swedish public broadcaster SVT. \"I\'m very pleased, I played very good tennis again, very aggressive with some good shots.\" Czech world number six Berdych defeated Spain\'s Nicolas Almagro in just 69 minutes without facing a single break point, 6-3, 6-2. Tsonga, ranked world number seven, and Berdych will both be gunning for a spot in the ATP World Tour Finals in November at the O2 Arena in London.
