WASHINGTON (AP) -- Last season, the Bobcats went 7-59 in the lockout-shortened season, the lowest winning percentage in NBA history, but have already equaled that victory total in their 12th game.
Washington fell to 0-11 despite the spark supplied by Nene, who energized the Wizards during most of his 29 minutes, but in the end, the Bobcats pulled out the win.
Martel Webster had 21 points for Washington and Nene scored 19.
Reggie Williams' 3-pointer, his only points of the game, gave Charlotte a 104-103 lead with 1:18 to play. The Wizards were called for a 24-second violation with 15.2 seconds left. Sessions made one free throw and Kemba Walker had two for a 107-103 lead.
Bradley Beal made a 3-pointer to draw Washington within 107-106 with 1.6 seconds to go. Walker made one of two free throws with 0.8 seconds to play, and Jordan Crawford missed a long heave at the buzzer.
The Bobcats appeared to have won the game in the first overtime, but Chris Singleton was fouled by Charlotte's Jeff Taylor as he attempted a 3-point attempt with 0.4 seconds to play. Singleton made the first, missed the second and converted on the third for a 99-all tie.
Nene returned to the game with just over four minutes left in regulation and Washington trailing 88-83. The Wizards scored the last six points of regulation to force the first overtime.
After missing the first nine games of the season with a foot injury, Nene played well in Washington's overtime loss to Atlanta.
In its first 10 games, Washington lost by an average of seven points. The only game in which the Wizards were totally uncompetitive was their 16-point loss in Charlotte on Nov. 13. Three of their 11 losses have been in overtime.
Nene came in with 3:08 to play in the first quarter as Charlotte was nearing the end of an 11-0 run to take a 25-12 lead with 2:14 to play.
He hit two free throws and sparked a 12-0 run to end the quarter, passing to Emeka Okafor with 14 seconds left in the first for a three-point play to cut Washington's deficit to 25-24.
After Nene hit on a three-point play and left the game with 9:30 to play in the second quarter, Washington had a 30-27 lead. Shaun Livingston hit two free throws with 8.2 seconds left in the first half to enable the Wizards to lead at the break, 51-50.
Nene began the second half on the bench as Charlotte quickly built a 64-53 lead four minutes into the third quarter.
He came in with 4:20 to play and along with eight straight points from Webster sparked Washington. The teams were tied at 72 after three.
NOTES: On Sept. 28, the Wizards announced that G John Wall would miss the first month of the regular season with a left knee injury. Coach Randy Wittman said that he won't hazard a guess on Wall's return. "I don't know where we're at. If I could give you a time, I would," Wittman said. "I have no idea. He has not practiced at all, so until that time comes, I don't know what the timetable's going to be." ... Washington F Trevor Booker missed his second straight game with a left knee injury. ... Charlotte G Gerald Henderson (sprained left foot) and F Tyrus Thomas (strained left calf) will continue to be out for "the foreseeable future," coach Mike Dunlap said. ... Three Bobcats -- Gordon, Taylor and F Michael Kidd-Gilchrist fouled out. ... According to STATS LLC., this was Charlotte's first double-overtime game since an Oct. 30, 2009, win over New York, and Washington's first since Mar. 23, 2011, when it lost to the Clippers in Los Angeles.
