Trail Blazers 106, Mavericks 104: LaMarcus Aldridge hit a game-tying 3-pointer with 4.5 seconds left and then buried the game-winner at the buzzer to give Portland an improbable win over visiting Dallas.

The Blazers erased a 21-point third-quarter deficit, lost a late lead and then fought back from seven points down in the final two minutes. Seven seconds after Dirk Nowitzki had given the Mavericks a lead with a 3-pointer of his own, Aldridge hit his first of the season and then nailed a turnaround 18-footer to win it after a Dallas turnover gave the hosts one last chance.

Aldridge had 29 points and 13 rebounds and J.J. Hickson added 26 points and 15 rebounds for Portland. Nowitzki scored a season-high 26 for the Mavericks, who took a 101-94 lead on Brandan Wright's basket with 2:18 to go.

Aldridge answered with a pair of free throws and Wesley Matthews added two more with 52 seconds left to pull the Blazers within 101-98. Nowitzki missed a 20-footer on the other end and Nicolas Batum tied it with a 3-pointer with 28 seconds remaining.

Shawn Marion then found Nowitzki for his tie-breaking shot from the arc with only 11.4 seconds left, but Aldridge, who had missed all nine of his 3-pointers this season, was left alone to tie it at 104. O.J. Mayo was then whistled for a charge, allowing for one dramatic possession for Portland.
