John Wall led all scorers with 27 points and also tallied nine assists and eight rebounds. Carlos Boozer posted 19 points and 12 boards for Chicago.
The Bulls were once again without Joakim Noah, Marco Belinelli and Richard Hamilton in this one, and they also lost Taj Gibson to a knee injury in the second quarter.
Chicago was unable to compensate for its lack of bodies this time around, as Washington outscored Tom Thibodeau's club 48-37 in the second half.
The Wizards are now an impressive 23-18 since Wall's return.
