Make it five in a row, as in number of games won in a row.

And Friday night at TD Garden, the Portland Trail Blazers defeated the Boston Celtics 109-96 to start off their four-game road trip on the right track.

“It’s an important game because it’s the first game of this trip,” LaMarcus Aldridge said before the game. “We have to take it one game at a time. I like our chances.”

Aldridge led Portland (7-2) with a game-high 27 points and 12 rebounds, earning his fourth consecutive double-double. Nicolas Batum struggled from the gate, clanking his first five shots. But he ended the game with 18 points on six-of-14 shooting to go along with his six assists.

Damian Lillard supplied 17 points and knocked down two threes. That’s important because he has made the most threes (212) by any NBA player in his first 100 games. Tonight’s game was only his 91st.
