Lin raved about Harden's performance.
"If he is not up for MVP consideration, I don't know what else he needs to do," Lin said. "He made every single big play down the stretch, and even the shots that I was able to have, they were created because of him."
Oklahoma City was up by seven points midway through the third quarter when Chandler Parsons scored six points in less than a minute to get Houston within 73-72. He made a pair of free throws before adding consecutive dunks. On the first one, Carlos Delfino stole the ball from Durant and passed to Parsons for the dunk. Lin stepped in front of a pass from Ibaka a few seconds later and found Parsons alone for the two-handed slam.
Oklahoma City was up by eight points with about 1 1/2 minutes left in the first half when Lin was given a technical for arguing a call. Durant made the free throw on the technical to put Oklahoma City's lead at 60-51.
Harden took over after that, scoring all of Houston's points in a 6-2 run to end the quarter and cut the lead to 62-57 at halftime.
Harden made four 3-pointers early to help Houston build a 34-22 lead in the first quarter. Oklahoma City scored seven straight points after that, before Harden added a pair of free throws to lead the Rockets up 36-29 at the end of the first quarter.
"I hadn't made four 3s all season in one game," Harden said. "I took some extra shots last night, that kind of helped me out with my confidence a little bit, just to get it going early — not trying to force it, but get my teammates involved and everything else was going to open up."
Parsons was helped off the court and into the locker room after twisting his right ankle near the end of the third quarter.
He returned with about 6 1/2 minutes left in the game.
NOTES: The Rockets reached agreements on two trades that will send Patrick Patterson, Cole Aldrich and Toney Douglas to Sacramento and Marcus Morris to Phoenix, a person familiar with the situation said Wednesday. The Rockets will receive Thomas Robinson, the No. 5 pick in last year's draft, Francisco Garcia and Tyler Honeycutt from the Kings, according to the person, who spoke on condition of anonymity because the deal had not been announced and was still pending league approval. ... Thunder center Kendrick Perkins missed Wednesday's game with a sprained right knee. ... Wednesday was Houston's ninth double-digit comeback win this season.
