James Harden broke out of a slump with a career playoff-best 37 points and Dwight Howard added 24 points and 14 rebounds for the Rockets.
LaMarcus Aldridge had more than 40 points in each of Portland's victories in the first two games in Houston. But Omer Asik did a good job of shutting him down in Game 3, holding the All-Star forward to 23 points. The Blazers were led by Damian Lillard with 30 points.
Portland trailed by as many as 11 points in the final quarter but Nicolas Batum hit a 3-pointer with 41 seconds left to tie the game at 110.
