Luka Doncic scored 41 points, Tim Hardaway Jr. added a season-high 31 and the Mavericks never trailed in the 137-123 romp of the Houston Rockets on Sunday afternoon.
The Mavericks scored 45 points in the first quarter and were up 78-60 at halftime. Hardaway had 19 in the half, Doncic 17 and Kristaps Porzingis 15.
"That first quarter killed us," Houston's P.J. Tucker said.
James Harden was asked what Houston did wrong defensively.
"Everything," he said. "We allowed them to do whatever they wanted to do from the beginning of the game and when you give a team like that comfort ... they gain confidence. And that's what they did."
The Mavericks has won five straight, scoring at least 137 in the last three. Houston has lost three straight after winning eight in a row.
