DENVER -- Russell Westbrook is forever linked to teammate Kevin Durant, but now the All-Star guard has joined elite company with another big night.

Westbrook had 13 points, 12 assists and 14 rebounds for his 17th triple-double of the season, and the Oklahoma City Thunder routed the Denver Nuggets 124-102 Tuesday night.

Westbrook recorded his eighth triple-double since the beginning of March and the 35th of his career. He is the first player to have 17 triple-doubles in a season since Magic Johnson did it for the Los Angeles Lakers in 1988-89.

"It's a great honor," Westbrook said. "Whenever you're mentioned in the same sentence as Magic, it's always great. That's something you never take for granted."

The Thunder guard notched the triple-double when he assisted on Andre Roberson's dunk midway through the third quarter. It was the seventh time this season he reached the mark before the start of the fourth quarter.

"I didn't know he had a triple-double until now," Nuggets guard Emmanuel Mudiay said in the postgame locker room. "I admire watching him play but when we're on the same court I like to compete."

Durant had 26 points and eight assists for Oklahoma City (54-24), which clinched the No. 3 seed in the Western Conference with the win. The Los Angeles Clippers could reach 54 wins, but the Thunder won the season series between the teams.

Enes Kanter had 18 points and 11 rebounds, and Dion Waiters and Serge Ibaka scored 18 apiece for the Thunder, who led by as many as 33 in winning their sixth straight against Denver.

"We didn't start the game all that well," Thunder coach Billy Donovan said. "Maybe the altitude had something to do with it but we started to get our legs underneath us as the game went on."

Gary Harris led the Nuggets with 17 points, and Mudiay and D.J. Augustin had 15 apiece. Denver (32-47) lost its third straight and fell for the fourth time in five games.

"One day we aspire to be like the Thunder, like the Spurs, like the Warriors," Denver coach Michael Malone said. "Teams that can win 60 games and do it with ease almost."

With Denver Mayor Michael Hancock looking on, the Thunder outscored Denver 36-21 in the second quarter to pull away. The Nuggets scored the first four points of the period, but Randy Foye started a 23-2 run with one of Oklahoma City's eight first-half 3-pointers that made it 59-39.

Anthony Morrow finished the explosive second with another from behind the arc to give the Thunder a 68-51 halftime lead.

The 68 points in the first half tied a team high for the season.

The Nuggets tried to make a game of it when Harris hit a floater to cut it to 12 early in the third quarter. However, Oklahoma City came on strong, outscoring the Nuggets 39-26 in the period to take a 107-77 lead into the fourth.

Westbrook didn't turn the ball over in the third quarter after having five in the first half. He finished with six points, seven assists and four rebounds in the second half despite not playing in the fourth quarter.

"Turnovers in the first half were my fault," he said. "I was throwing the ball away too much. I made a conscious effort on the second half to not turn the ball over."

He did enough to impress his teammates.

"Every time I see him on the floor, it could be a historic night," Morrow said. "I tell him every day that it's unbelievable seeing him do this and I want him to keep it going."

NOTES: Thunder coach Billy Donovan said he doesn't plan on resting players down the stretch even though his team is virtually locked into the No. 3 seed for the Western Conference playoffs. He said he would sit players if they are banged up. "We want to make sure that there are no problems with their health," Donovan said. "We don't want to get them run down." ...
