Dirk Nowitzki scored 16 of his 30 in the third quarter to break open a tight game and send the Mavericks to a 103-93 victory over the winless Miami Heat on Monday night.
Steve Nash added 18 points and 11 assists, Tony Delk 17 points and Antoine Walker 13 points and nine rebounds for Dallas.
Udonis Haslem had 20 points and 12 rebounds, John Wallace 19 points and Lamar Odom 17 points and nine assists for the short-handed Heat.
Miami was missing key players Eddie Jones (sore right hand) and Dwyane Wade (left hip pointer). Samaki Walker was placed on the injured list Monday with an injured right shoulder.
The Heat signed rookie free-agent guard Kirk Penney earlier Monday to bolster its bench, and Penney played 14 minutes in his NBA debut.
Nowitzki's 3-pointer with 6:23 left in the third quarter gave the Mavericks the lead for good at 58-55. Dallas closed the quarter with a 10-1 run capped by Nowitzki's 20-foot jumper with 34 seconds left. The Mavericks took a 74-64 edge into the final quarter.
REALIGNMENT PLAN: The expansion Charlotte Bobcats would join the NBA next season in a division with one playoff team from last season.
Under a plan to accommodate the NBA's 30th team, the league is planning to realign from four divisions to six five-team divisions.
The Bobcats would be joined by the Wizards, Hawks, Heat and Magic, deputy commissioner Russ Granik said. Orlando is the only team that had a winning record last season.
