Joakim Noah tallied 21 points and 12 rebounds, while Carlos Boozer added 16 points for Chicago, which has won five straight games and moved one-half game ahead of Toronto for the third seed in the Eastern Conference. The Raptors are currently in Milwaukee playing the Bucks.
John Wall had 20 points and six assists and Marcin Gortat supplied 19 points and eight boards for the Wizards, who had won four of their last five tilts coming into the game.
The Bulls had the Wizards doubled up by the break, 52-26, but Washington outscored them, 35-24, to whittle the deficit making it a 76-61 game heading into the final frame.
Chicago, though, began the fourth on a 12-2 run to put the game away. Noah put in the first seven points of the surge and Augustin capped it with a triple for a commanding 88-63 cushion.
Noah finished off an earlier 12-2 burst with a dunk to stake the Bulls to a 19-8 advantage with 4:03 to go in the first. An extended 18-4 flurry that bridged into the second extended the margin to 42-18 a little past the midway point of the stanza.
