"I thought we played well up until the last five or six minutes of the game," Phoenix coach Alvin Gentry said. "I thought P.J. (Tucker) did about as good of a job as you can on Kevin (Durant). It's really difficult to think you're going to be able to stop the Thunder every single time with (Westbrook and Durant) on the court."
Durant recorded his 13th outing this season of 30 points or more, but had a poor shooting night, finishing 11-of-24 from the field. Westbrook, who has struggled with his shot in recent games, finished 7 of 16. Ibaka scored 16 points, Sefolosha added 14 points and Collison had 10 points and nine rebounds for the Thunder.
Goran Dragic added 16 points for Phoenix, while Marcin Gortat had 12 points and 10 rebounds and O'Neal had 12 points.
"We have a problem of closing out the games," Gortat said. "We just don't know how to execute in the last few minutes and we have to work on it. That's it."
The Thunder led 54-53 at halftime, but lost Westbrook temporarily after he was inadvertently elbowed while attempting a layup with 1:32 left in the half. Westbrook went down, bleeding from around his right eye, as no foul was called and play continued.
"It's just part of the game," Westbrook said of the injury. "Stuff like that happens and you've just got to be prepared for it."
The Suns stayed in the game in the half by shooting 51.2 percent from the field and 42.9 percent (6 of 14) from 3-point range. Sebastian Telfair hit three 3-pointers in four attempts in the first half but didn't score again.
