In a 114-106 overtime victory over the Orlando Magic at the Amway Center, Westbrook finished with 57 points on 21-of-40 shooting, grabbed 13 rebounds, and dishing out 11 assists in 41 minutes of action.
His 57 points are the most in NBA history for a player with a triple-double.
It's also the second time this season that Westbrook had gone over the 50-point mark with such a line. It was during Oklahoma City's second game on Oct. 28 against the Phoenix Suns when the now 28-year-old had 51 points, 13 boards, and 10 dimes.
Now with 38 triple-doubles, Westbrook needs three more to tie Oscar Robertson's single-season record of 41, which he set in 1961-62 with the Cincinnati Royals. He also needs three more to tie Wilt Chamberlain's 78 career triple-doubles for fourth all time.
The Thunder own a record of 43-31, and have eight more games remaining on their schedule.
