Aldridge was hurt less than two minutes into the game when he landed on Trevor Booker's foot, let out a cry and fell to the ground holding his ankle. The power forward was helped off the court and did not return, although the team reported that X-rays were negative.
"I think when he went down, the life went out of us," Camby said. "It's sad but true."
The Wizards (7-22) were coming off an electrifying comeback win over Detroit in which they had a 39-10 second-half run.
"It shows that we can definitely compete with anybody," Crawford said. "We just have to do it tonight."
Portland had lost its previous two at the Rose Garden after starting the season 11-1 at home. The Blazers had a demoralizing 97-94 double-overtime loss to Dallas on Saturday that led to widespread criticism of Portland's starting guards, Wesley Matthews and Raymond Felton, who combined for 16 points on 7-of-27 shooting.
One day after icily defending his rotation to the media, Portland coach Nate McMillan started Batum in place of Felton. The 6-foot-9 Batum responded quickly, scoring 11 points in the first quarter.
However, Portland looked deflated after losing Aldridge. The Wizards dominated the boards, and Young, Wall and Crawford punished a sagging Blazers defense both from outside and with dribble penetration. The Wizards led 58-46 at the half.
"There was no defense," McMillan said. "We didn't control the ball at all tonight."
The Blazers put together two small runs but never seriously contested the lead. Portland cut the lead to seven but the Wizards made nine straight shots, with Young hitting back-to-back 3-pointers and Wall going coast to coast to put the Wizards up 78-63 with 6:55 left in the third.
Wallace scored eight straight points for Portland to cut the lead to 115-107 with 2:30 left in the game, but Young knocked down another 3 and JaVale McGee dunked to put the game out of reach.
Portland last lost three in a row at home between March 29 and April 6, 2008. ... McGee had his 10th double-double of the season with 18 points and 11 rebounds for Washington. ... The Wizards are 5-7 under coach Randy Wittman, who replaced Flip Saunders after a 2-15 start.
