The Slovenian superstar finished with 34 points, 10 rebounds and 10 assists.
It was his third triple-double from his past six games, with the hot streak including the first 60-20-10 game in league history.
Christian Wood (28 points) and Tim Hardaway (18) also fired as the Mavericks (23-17) won for the eighth time in nine games.
But they were no match for the Mavericks, who built a first-quarter lead when Wood took control early in the game.
Elsewhere, Boston maintained the league's best record with a Jayson Tatum-inspired 121-116 win over San Antonio.

Dennis Schroder made a pair of free throws with 3.6 seconds left to put the Lakers ahead before Kings guard De'Aaron Fox (34 points) missed a half-court shot on the buzzer.
Zach LaVine (26 points) was the difference for Chicago in a 126-118 win over Utah, making three consecutive triples in a crucial run during the final quarter.
Golden State suffered a second straight home loss, this time 115-101 to Orlando.
