Oklahoma City’s Russell Westbrook breaks triple-double record in Thunder’s victory over Denver.

DENVER — Russell Westbrook broke Oscar Robertson’s 56-year-old record with his 42nd triple-double of the season Sunday, then he broke the Denver Nuggets’ hearts with a buzzer-beating three-pointer for a 106-105 victory.

The loss eliminated the Nuggets from playoff contention.

Westbrook had 50 points, 16 rebounds and 10 assists in breaking Robertson’s record of 41 triple-doubles that stood since the 1961-62 season.

Westbrook’s record-breaking assist came with 4:17 remaining after a series of missed shots delayed his historic moment

With his triple-double in the books, Westbrook scored his team’s final 13 points, including a three-pointer as the buzzer sounded after a timeout with 2.9 seconds left.

Kyle Single inbounded the ball to Steven Adams, who fed Westbrook for the winner.

Danilo Gallinari scored 22 of his season-high 34 points in the third quarter to lead the Nuggets, who were hoping to take the race with Portland for the final Western Conference playoff spot down to the final two games.

Before tip-off, Nuggets Coach Michael Malone said he wouldn’t care if Westbrook broke the record so long as it came in a loss.

The Thunder are locked into the sixth seed and will face Houston in the first round of the playoffs in a showdown between Westbrook and his chief rival for the MVP award, Rockets point guard James Harden.

Westbrook had 23 points, 12 rebounds and 6 assists by the time the Thunder went to the locker room trailing 53-52 at halftime at the Pepsi Center.

Westbrook nearly had his 10th assist with two minutes left in the third quarter but Enes Kanter lost the handle going up for the basket and Westbrook took a seat until the fourth quarter.

Westbrook fed Semaj Christon in the right corner for a three-pointer that pulled the Thunder to 101-91 and gave Westbrook his record.
