With 32 points, 13 rebounds, and 10 assists in 33 minutes of action, Harden became just the sixth player in NBA history to register multiple 30-point triple-doubles in the playoffs.
"He's a machine. He just scores," Rockets head coach Mike D'Antoni said of Harden postgame.
Harden nearly notched a triple-double in the first half alone, posting 25 points, seven rebounds, and seven assists to help Houston lead by 26 at halftime.
The Rockets take a 2-0 series lead to Salt Lake City for Game 3 at Vivint Smart Home Arena on Saturday.
