Jordan Crawford had 27 points, 11 rebounds and 11 assists to lead the Wizards. Nene scored 18 points, Bradley Beal had 17 and Martell Webster 11.
Beleaguered Wizards coach Randy Wittman snapped at fans who chided him for removing Nene from the game during overtime. Nene has been hampered by a foot injury, and Wittman has tried to limit him to 20 minutes. On Tuesday, he played 24, but that didn't satisfy the crowd.
"I had fans heckling me," Wittman said. "They're killing me. I had to turn around and say something to them today."
After Washington took a 93-92 lead on a jumper by Earl Barron with 3:05 to play in overtime, the Hawks scored six straight points to go up five with 1:29 to play.
Williams hit one of two free throws to tie the score, and DeShawn Stevenson hit a three-pointer with 2:08 left to put Atlanta back ahead for good, 96-93.
