James Harden has now gone 27 straight games of scoring more than 30 points.
The 29-year-old is only eclipsed by NBA legend Wilt Chamberlain.
Harden admits he feels like he has “got some making up to do” after the slow start the Rockets had to the season, but considers it “great company” to keep following his current scoring streak.
“I’m just going to keep going,” Harden said.
“Nothing can slow me down, nothing can stop me.”
Harden scored 44 points at the Talking Stick Resort Arena and also added eight rebounds, six assists and three steals.
Last year’s MVP shot 15 of 26 from the floor and also added nine from the free-throw line to resign Phoenix to their 11th consecutive defeat.
It was Harden’s 20th 40-point game on the season and he puts his streak down to “just being aggressive” and “trying to do whatever it take to help my team-mates”.
Rockets coach Mike D’Antoni praised his superstar after the game.
“He’s seen everything, he is going to score,” he said.
And that sentiment was echoed by Harden himself.
“I’ve seen that defence many times over the course of this year, it’s no different,” he said.
Harden had notched up 22 points before the half and was the only person for the Rockets to reach double figures before the intermission.
However, in the second half Houston’s scoring was spread out among several players, with Kenneth Faried hitting up with a double-double, with 17 points, 14 rebounds.
James Ennis III scored 13 points and Chris Paul put in an impressive performance with 18 points, five rebounds, five steals and four assists.
Despite never trailing in the game, Harden was disappointed with how the Rockets performed in the third quarter.
“We allowed them to put too many easy layups,” Harden said.
“We kind of relaxed being up 18, late in the third quarter, we got to close those games out, go 20 in and cruise the fourth quarter.
“But give a team confidence, especially a young team who have a lot of energy, they made some big shots and turned the ball over and we had to calm down a little bit.
“We closed the game off the right way.”
Despite being asked several questions about his current streak Harden stressed the importance of doing “whatever it takes” to help his team-mates.
“Trying to give that same courage some motivation to my team-mates,” he said.
“Regardless about scoring, its about going up there and attacking the game.
“Being aggressive with the game of basketball, defensively, offensively, that’s all I can give to them.
“Once we get it together, get all our pieces together and being able to catch a rhythm the game will be a lot more easy for all of us.”
