Dirk Nowitzki, playing only in the first half in his return from an Achilles strain after missing 14 consecutive games, added 17 points and Wesley Matthews 16 for the Mavericks.
Jamal Crawford scored 26 points for the Clippers, who were playing without both of their stars, Chris Paul (hamstring) and Blake Griffin (knee).
Their bench turned in another strong effort, outscoring the Mavericks’ reserves 54-21. The previous night, the Clippers bench outscored the Spurs’ 58-33.
But the Clippers turned the ball over 20 times and could not maintain a late lead.
