TORONTO -- Kevin Durant scored 34 points and Russell Westbrook, with his 16th triple-double of the season, added 26 as the Oklahoma City Thunder extended their winning streak to a season-high eight games with an emphatic 119-100 victory over the Toronto Raptors on Monday night.

The victory gives Oklahoma City (52-22) its best stretch since a 10-game run from Jan. 16-31, 2014. Westbrook's triple-double tally is the most since Magic Johnson's 17 in 1988-89 while Durant scored 20-plus points for the 59th straight game.

Toronto (49-24), the only NBA franchise without a 50-win season on the books, was hoping to become the fifth team this season to hit 50 victories -- joining Golden State, San Antonio, Cleveland and Oklahoma City. The Raptors will look to hit the plateau Wednesday when Atlanta visits.

Westbrook finished with 11 rebounds and 12 assists. Durant added eight and eight.

DeMar DeRozan led Toronto with 19 points. Norman Powell had 18 and Kyle Lowry 14 for the Raptors, who led just once in the game.

Trailing 97-74 after three quarters, Toronto cut the lead to 14 in the fourth. But the night belonged to Oklahoma City.

Asked beforehand if the game was a litmus test, Toronto coach Dwane Casey replied: "Well I don't know if it's a litmus test. It's a hell of a test, I know that, against OKC?"

Oklahoma City came into the game the hottest team in the league, with an average margin of victory of 16.9 points during its win streak.

The Raptors were coming off a weekend win over the injury-plagued Pelicans in New Orleans, following road losses in Houston and Boston.

It was a sloppy start for both teams but the Thunder regrouped quicker. Toronto missed its first five shots and trailed 15-3 early. An 11-2 Raptors run helped reduce the lead to 27-21 at the end of the first quarter that saw Toronto hit on just seven-of-22 shots.

It took Lowry two minutes into the second quarter to finally make a field goal. But that three-pointer was part of a 10-0 run that gave Toronto its only lead at 31-30.

The Thunder promptly reeled off 11 straight points to restore its lead.

Casey was assessed a technical late in the second quarter after Toronto big man Bismack Biyombo was mobbed under the Thunder basket without a call. The half ended on a Westbrook dunk that gave the visitors a 61-48 lead.

Lowry and DeRozan were a combined eight-of-25 shooting (22 points) in the first half while Westbrook and Durant were 10-of-23 (31 points). The Thunder duo also had 11 first-half assists, compared to six for the Toronto stars.

Oklahoma City increased the lead to 25 in the third. Casey's issues with the officials continued and he was left holding his head when Jonas Valanciunas was called for a foul on what seemed like some stiff defence. The Thunder led by 23 after three quarters that saw Toronto mired in 28-of-71 shooting.

Durant, with his 11th point of the night, passed Canadian Steve Nash (17,387) for 79th on the league's all-time scoring list. He did it with an acrobatic off-balance alley-oop in the second quarter.

The Toronto stop was the first of seven outings on the road in the Thunder's nine-game regular-season finale. Next up is a stop Tuesday in Detroit.
