Portland (30-33), making a push for the postseason, used a strong finish to seal the victory. The Trail Blazers had lost three of their last four games before Wednesday's win.
The Grizzlies, playing the second game of a back-to-back, received 24 points from Jaylen Wells and 20 from GG Jackson but fell to 3-9 in their last 12 games. Memphis continues to be without Ja Morant, who missed his 18th consecutive game with a left elbow injury.
