He had 12 points and 11 rebounds. Wittman wasn't pleased with how his team closed out the game.
"Disappointed in that, but there's not a bad win in this league. We'll take the win," Wittman said.
Atlanta coach Mike Budenholzer, whose team played well despite missing three of its five leading scorers, had been hoping for a comeback.
"It's amazing how long an NBA game is and what can happen in the last two minutes," Budenholzer said.
The game was interrupted countless times by the condensation, which seemed to bother Wizards players more than Hawks. It was reminiscent of a Jan. 11 game that featured two lengthy stoppages when a heavy rainstorm hit the area and delayed Washington's game with Houston.
The Hawks started hot, hitting seven of their first eight shots and running out to a 21-11 advantage, but Washington got eight late points from Gooden, outscoring the Hawks 16-7 in the last 4:31 to lead 28-27 after one.
Thanks to nine points in the last five minutes by Pero Antic, Atlanta led 52-50 at halftime.
Wall's third-quarter offensive display gave the Wizards a 75-71 lead after going into the fourth.
NOTES: Washington F/C Nene, who has missed 17 games with a left knee sprain is progressing, though Wittman isn't guessing when he may return. "He's going on the floor a little bit, on his own, just kind of getting on his legs a little bit," Wittman said. "Where that takes us I don't know. He's going in a good direction." ... Atlanta was without G/F Kyle Korver (back spasms) and G DeMarre Carroll (stomach virus). ... Wizards G Andre Miller was called for a flagrant foul on Hawks G Dennis Schroder in the fourth quarter, but Schroder missed both foul shots.
