Wesley Matthews scored 12 of his 20 points in the first quarter, and the Dallas Mavericks cruised to a 112-80 victory over the Orlando Magic on Saturday night.

Dirk Nowitzki scored 14 points in 18 minutes, hitting a 3-pointer to give Dallas its first 30-point lead at 67-37 in the first minute of the third quarter before going to the bench for good a little more than six minutes later.

The Mavericks won for the sixth time in eight games _ including three victories against division leaders _ in what's becoming a turnaround season.

Dallas' first meeting with the Magic in November was in the middle of an eight-game losing streak, which was the longest for the Mavericks in 19 years and ended with them at 2-13.

Bismack Biyombo scored 15 points, nine in a meaningless fourth quarter, as the Magic lost their fourth straight.
