Brandon Roy added 20 points and five assists for the Blazers. Portland hit 20 of 22 free throws and outrebounded Houston 51-33.
Aaron Brooks had 19 points for the Rockets, who defeated Portland in six games this past spring in the first round of the playoffs.
That was a much different Houston team, though. Rockets center Yao Ming is out for the season after offseason foot surgery, and Ron Artest - who pestered the Blazers - left for the Lakers as a free agent.
