Andray Blatche led Washington with 20 points, and Nick Young had 16. The Wizards haven't won since Feb. 28.
Utah closed within a half-game of behind Denver for the Northwest Division lead. After a disappointing effort Friday night in a 122-106 loss to Indiana, the Jazz had the perfect opponent to regain their form.
The Jazz led for the final three quarters of the game and took control in the third quarter. Utah made 11 of its 14 shots in the third and outscored the Wizards 8-1 over the final 2 minutes of the quarter.
Boozer had a big dunk with a minute left, and Wesley Matthews converted a three-point play with less than a second left to give the Jazz a 80-65 lead going into the final period. Utah's lead never dipped below 10 the rest of the game.
Utah was missing star forward Andrei Kirilenko, who sat out for the fifth time in six games with a left calf injury. Kirilenko missed four games before playing into the fourth quarter Friday. Kirilenko, averaging 11.9 points, said he would have an MRI exam on Sunday.
C.J. Miles took Kirilenko's spot in the starting lineup and scored 10 points.
Utah took the lead late in the first quarter and built the lead to double digits in the second. The Jazz led by 12 with 30 seconds to go in the half before Young gave the Wizards some life by scoring five straight points, including a buzzer-beating 3-pointer, cutting Utah's edge to 50-43 at halftime.
