LaMarcus Aldridge had 18 points and 13 rebounds for this fourth straight double-double and the Portland Trail Blazers beat the Indiana Pacers 88-82 on Thursday night.

Damian Lillard led all scorers with 23 points for the Blazers, who have won three straight and 12 of their last 13.

Rodney Stuckey had 16 points for the Pacers, who have lost three straight to open a four-game road trip.

The Pacers tied the score at 64 early in the fourth quarter, but Portland built a 75-66 lead after Nicolas Batum's 3-pointer and Lillard's jumper. Stuckey hit a jumper that pulled the Pacers within 83-80 with 53 second left, but they couldn't get any closer.

The game was marked by heightened security when a group of protesters converged on the Moda Center. The group was marching against a New York grand jury's decision not to indict a white police officer in the chokehold death of an unarmed black man.

Security at the arena shut down several entrances during the game and there was a large police presence both inside and outside the facility.

The Pacers toyed with their lineup before the game, moving Stuckey to the point guard position and Donald Sloan to the bench. Forward Chris Copeland also got a starting nod.

A disabled motorized blimp in the arena that got stuck received much of the attention in the first quarter, providing a distraction from the slow start for both teams.

The Blazers shot just 6 for 24 (25 percent) and led 16-14 at the end of the first quarter. The Pacers were 7 for 21 (33 percent). It was a season low for points for the quarter for both teams.

Portland went up 32-24 midway through the second on Batum's long jumper. But the Pacers closed the gap, pulling within 32-31 with 3:04 left before the half.

The Blazers never surrendered the lead and led 38-33 at the break.

The game got chippy in the third quarter when David West appeared to shove Robin Lopez, and teammates stepped in to separate the two. West was whistled for a technical foul.

Batum dunked to give the Blazers a 51-44 lead halfway through the third. Portland stretched the lead to as many as 10 points, but Luis Scola's layup tied the game at 64.

Portland's 10 home wins are the most in the NBA.
