Mr. Triple-Double has done it again, folks.

By gathering his 16th rebound early in the third quarter of the Oklahoma City Thunder's game against the Memphis Grizzlies on Wednesday, Russell Westbrook clinched a triple-double average for the second successive season -- something no NBA player has ever done. 

Last season, Westbrook broke Oscar Robertson's NBA record by posting 42 triple-doubles, and became the only player other than Robertson to average a triple-double for an entire season. Westbrook was rewarded for his accomplishments with last year's NBA MVP award.

With much less fanfare this season, Westbrook quietly -- well, as quiet as Westbrook can be -- once again put up incredible numbers, and entered Wednesday's game needing 16 rebounds to clinch a second successive triple-double average. He was well on his way with 11 rebounds in the first half alone.

Many will point to the arbitrary nature of triple-doubles and venture that they shouldn't be as important as they've become to basketball, but the fact remains that Westbrook has done something no other player in the history of the NBA has done, which can never be taken away from him.

Now he'll look to lead the fourth-seeded Thunder to a victory in their opening-round playoff series against the fifth-seeded Utah Jazz.
