MEMPHIS, Tennessee — Jeff Green led Memphis' offense, but it was his defense that shut down Russell Westbrook.
Green scored 22 points and Marc Gasol added 19 as the Grizzlies defeated the Oklahoma City Thunder 100-92 on Friday night.
But it was a defensive switch to put Green on Westbrook in the second quarter that stymied Westbrook the rest of the night. After scoring 12 points in the first quarter against the Memphis point guards, coach Dave Joerger put the 6-foot-9 Green on the 6-foot-3 Westbrook.
From there, Westbrook scored six points, making only one of 11 shots from the field in the final three quarters.
"I didn't want to go to that in the first quarter," Joerger said. "Once we got through the first quarter, we kind of went to it and gave (Westbrook) a different look."
Zach Randolph finished with 14 points for Memphis, while Mike Conley and Courtney Lee scored 13 apiece. Nick Calathes contributed 10 as Memphis moved into a tie with Houston for the second seed in the Western Conference and top spot in the Southwest Division.
Enes Kanter led the Thunder with 24 points and 17 rebounds. Westbrook scored 18, but connected on only five of his 20 shots. Anthony Morrow and Kyle Singler scored 13 each.
"Both teams played physical, and both teams made it very hard during spurts," Thunder coach Scott Brooks said. "We missed a bunch of layups, and we missed some free throws (16 of 26), and we missed some good looks at 3s."
Memphis held a nine-point lead with 3 minutes left, but the Thunder got a three-point play from Kanter and a floater from Steven Adams to cut the lead to 92-88 with 2:14 left.
Oklahoma City was unable to get closer the stretch as the Thunder dropped their fourth of the last five, but still maintained a slight half-game hold on the conference's final seed over the New Orleans Pelicans, who defeated Sacramento 101-95 Friday night.
"They are one of those teams that is going to grind you down at the end of the shot clock," Morrow said of Memphis. "They'll take 23, 24 seconds to get their shot off. Down the stretch, they just grinded us down."
The Thunder led through much of the first half as Westbrook was not only scoring early, but putting pressure on Memphis' point guard.
Westbrook was determined to post up Conley early, then Calathes was put on the Thunder's leading scorer. By early in the second frame, both Memphis point guards were saddled with three fouls.
But Green and the Grizzlies defense changed the momentum, helping Memphis take a 55-49 lead into halftime.
"It has nothing to do with me. It was a team effort," Green said of his defense. "If coach is going to put me on Russell, my job is to take on the challenge of being in front of him and doing my job."
Westbrook's assessment of the defensive change amounted to "not much. It just stopped the post up. That was about it. That's normal."
The Thunder pulled even as Kanter took over in the early stages of the third, but the Grizzlies scored nine straight points to carry a 77-69 lead into the final frame.
"We are trying to win out for the rest of the year," Lee said. "Houston is right there with us competing for that second spot. That's the best thing we can do is just try to win all the games."
