PORTLAND, Ore. — Gerald Wallace had 31 points and sparked a key third-quarter run to lead the Portland Trail Blazers to a fast-paced 107-96 victory over the Los Angeles Lakers on Thursday night.

LaMarcus Aldridge added 28 points and 10 rebounds for Portland, which led by as many as 14 points. The Blazers had just four turnovers despite pushing the tempo for the entire game.

The Blazers sit atop the Western Conference at 5-1 — their lone loss coming on New Year's Day at the Clippers.

Kobe Bryant scored 30 points despite a torn ligament in his right wrist, and Andrew Bynum had 21 points and 12 rebounds for the Lakers, who have had trouble at the Rose Garden with losses in 11 of their last 13 game in Portland.

Los Angeles went 0 for 11 from 3-point range.
