The Thunder had a one-point lead going into the final quarter and clamped down defensively by holding the Rockets to 6-of-19 shooting over the final 12 minutes.
"Our turnovers hurt us and our lack of movement," Rockets coach Kevin McHale said.

Reggie Jackson filled in nicely Friday with 17 points, seven rebounds and eight assists.
"He's a guy that can continue to lead us as the playoffs go along," Thunder coach Scott Brooks said. "When we brought him in Reggie became a better player. The guy laid everything on the line."
A pair of free throws from Harden boosted Houston's lead to 72-62 with 5:48 left in the third quarter.
