The German was encouraged that even after a poor first lap that dropped him into the midfield, he was still able to come back through to sixth place.
"I had a really good start but then I didn't do the best of jobs on the first lap so I fell back a bit. From then on the race really went well," Rosberg said in his personal video blog.
"It was a great strategy and one [place] by one I just moved up and finished the race in sixth, so that was really good and I'm pleased with that.
"I think and hope that as a team this is the turning point and from now on we can steadily progress and close the gap to the front. That would be great. All in all I think it was a positive weekend going in the right direction."
