Despite coming into the encounter on a six-game winning streak, the Houston Rockets had no answers for a red-hot Toronto Raptors team on Tuesday night.
The Raps came away with a 129-113 win at the Toyota Center to stun the Western Conference powerhouse in their gym.
Toronto was able to secure the impressive victory behind a record-breaking second quarter where they put on an offensive clinic.
Dwayne Casey's men set a franchise record for the most points in the second quarter by dumping 45 on the Rockets as part of a 76-point first-half effort.
The Raptors shot 13-of-18 from the field to go along with 16-of-20 from the free-throw line while recording eight assists and three triples.
Houston entered the contest with the eighth-ranked defence in the league but they were powerless to stop a Raptors team firing on all cylinders.
DeMar DeRozan led the visitors in scoring as he posted 27 points to go along with six rebounds and five assists.
His backcourt partner Kyle Lowry added a double-double of 19 points and 10 assists against his former team as the Canadian franchise moved to 8-5 in the east.
This was a terrific bounce-back win for Toronto after they were narrowly beaten by the Boston Celtics on Sunday.
They have struggled to close out games against good teams so far this season - losing to the San Antonio Spurs, Golden State Warriors an Boston - but managed to pull away in style in Houston to hold off one of the best offensive teams in the league.
"Liking this feeling," DeRozan said. "You've got to love this feeling so you don't got to go out there having too many of them close games that you lost, feeling upset, got to wait until the next game. You've got to want to continue to have this feeling and that should work out everything else."
As well as their All-Star duo, the Raptors got big performances from C.J. Miles, who poured in 19 points off the bench, and rookie OG Anunoby, who added 16 points in his first start.
The 20-year-old was given the difficult task of guarding James Harden and was praised for his efforts by his head coach, despite the Rockets superstar tallying 38 points and 11 assists.
“You’re not going to stop a young man like Harden, but I thought he made him work for every inch of the court he tried to get to, and used his foot speed and length to make it difficult,” Casey said of Anunoby.
“(Harden) still scored. Still, he made him work and that’s what we need out of that position.”
The Raptors have been quietly going about their business so far to begin the campaign but they have caught people's attention with this eye-catching win.
