The AP reports:

The Dallas Mavericks decided they were going to treat Game 6 of their first-round playoff series against the Trail Blazers as if it were Game 7.

Nowitzki scores 33, Mavs eliminate Blazers

“We talked about it before, we talked about it again during the game, how we had to keep fighting,” said Dirk Nowitzki, who had 33 points and 11 rebounds as the Mavs held off Portland 103-96 on Thursday night to advance to a second-round matchup with the defending champion Los Angeles Lakers…

Jason Terry finished with 22 points as the Mavericks snapped the home-court advantage that each team had held during the playoffs and the regular season.

The Blazers led by as many as 12 points early after Gerald Wallace went on a tear with 13 first-quarter points. But Wallace left the game for much of the second quarter with a sore back and Portland surrendered the lead.

Wallace would return to finish with 32 points and 12 rebounds. LaMarcus Aldridge added 24 points and 10 rebounds.

Led by Wallace, the Blazers jumped out to 19-7 lead, capping the quarter with a dunk from rookie Chris Johnson to make it 27-19.

But the Blazers went cold when Wallace headed to the locker room with lower back tightness, and the Mavericks went on a 16-4 run to tie it at 35 after J.J. Barea’s layup.
