The Trail Blazers pulled ahead of the Lakers early and, after absorbing a charge led by rookie guard Jordan Clarkson, pulled away late to beat the Lakers, 107-77, on Friday night at Staples Center.
Blazers reserve guard C.J. McCollum scored 27 points in 27 minutes, making 10 of 16 shots from the field. Portland All-Stars Damian Lillard (20 points) and LaMarcus Aldridge (14) both played less than 30 minutes in the victory.
Clarkson matched McCollum with 27 points and finished with seven rebounds and five assists -- but his teammates struggled to make shots for most of the night. The Lakers shot only 37.8% from the field and 35.7% (5 of 14) from three-point range.
The Blazers shot 48.9% and 38.5% (10 of 26), respectively. Portland didn't miss a free throw in 11 tries, while the Lakers shot 58.8% (10 of 17) from the line.
Wesley Johnson tied a career high with 15 rebounds to go along with 11 points. Tarik Black scored 10 but no other Laker reached double figures.
UCLA product Arron Afflalo added 17 while Robin Lopez scored 10 for the Trail Blazers.
Point guard Dwight Buycks made his season debut after signing a 10-day contract earlier in the day with the Lakers. Despite not practicing with the team, Buycks scored eight points on three-of-four shooting in six minutes.
With the loss, the Lakers fall to 20-55. They'll next host the Clippers (50-26) at Staples Center on Sunday. The Trail Blazers (49-26) host the New Orleans Pelicans (41-34) on Saturday.
