Recording a triple-double for the 42nd time this year, Westbrook has now beaten Hall of Famer' Oscar Robertson's record for most triple-doubles set in 1961-2.
The 6'3 (190.5cm) point-guard from Lawndale, California is the first man in 55 years to average a triple-double.
This means he has averaged at least 10 for scoring, assists and rebounding for an entire NBA season (82 games).
The 28-year-old broke Robertson's record on the road, in a buzzer-beating win against the Denver Nuggets.
