Paul Millsap added 15 rebounds and 13 points. Al Jefferson also had a double-double with 14 rebounds and 12 points.
The score was tied at 70 before Mo Williams hit back-to-back 3-pointers then scored on a driving layup. Marvin Williams followed with his second 3-pointer, putting Utah up 11 points with 2:57 left in the third. The Jazz led by as many as 20.
Darren Collison scored 17 points for the Mavs, who pulled off an upset win over the Los Angeles Lakers on Tuesday but couldn’t match Utah’s pace in the second half.
The Jazz held a 44-30 advantage on points in the paint and 61-40 edge in rebounds as Dallas continued to play without 11-time All-Star forward Dirk Nowitzki and 7-0 center Chris Kaman.
