MEMPHIS, Tenn. >> Oklahoma City’s efficient offense made it a fun night for the Thunder. And a miserable game for the Memphis Grizzlies.

Kevin Durant had 32 points, 10 rebounds and six assists, leading the Thunder to a 125-88 rout of the Grizzlies on Tuesday.

“When we play together like that, we make the game easier,” Durant said. “We were just playing smooth basketball. It was beautiful to watch. It was a fun game to play.”

Russell Westbrook added 13 points and 16 assists as the Thunder built the lead to 35 through three quarters and coasted to their second straight win.

Serge Ibaka scored 17 for Oklahoma City, and D.J. Augustin had 13. Dion Waiters finished with 12 points.

“I think it’s the worst loss we’ve had against them, especially at home,” said Memphis forward Zach Randolph, who had nine points and 10 rebounds.

Mario Chalmers led Memphis with 19 points, and JaMychal Green and Marc Gasol had 11 apiece. It was the most points given up by Memphis this season.

The Thunder lead was large enough that the starters, including Westbrook and Durant, sat out the fourth quarter.

“I can’t say enough about what Russell did,” Thunder coach Billy Donovan said. “In my opinion, he’s one of the rare guys in this league that can dominate a game without scoring.”

Durant was 11 of 14 from the field and 6 for 6 at the line. He also went 4 for 5 from beyond the arc, leading a 13-for-26 performance from 3-point range for Oklahoma City.

“When you look at the numbers, it’s pretty simple,” Memphis coach Dave Joerger said. “You know one team made shots and the other team struggled to make shots. Our defensive intensity wasn’t where it (should have been).”

The Thunder went small while closing the first half on a 13-4 run for a 59-47 lead at the break. Durant was 6 of 8 from the field for 19 points, and Westbrook had a dozen assists in the half.

Oklahoma City opened a 69-51 lead less than four minutes into the third, causing Memphis to call timeout.

With 3 minutes still remaining in the third, Westbrook had already matched his season high with 16 assists, helping Oklahoma City increase its advantage to 98-63 entering the fourth. The Thunder outscored the Grizzlies 39-16 in the third.

“We played poised,” Durant said. “We played under control and a team that usually packs the paint on us, we spread them out, and we were able to make the extra pass. We played tough basketball.”

RUSSELL’S ASSISTS

BIG LOSSES
