Washington, though, opened the fourth with a big run of its own, scoring 12 unanswered points, including 3-pointers Ariza and Jordan Crawford and went in front 92-87 with 9:36 left to play.
"We let them get hot," Lawson said. "When a team comes into your building and gets confidence like that, it is hard to stop them."
The Nuggets closed to 100-97 on successive baskets by Miller and Lawson with 3:46 remaining. A putback by Seraphin put the Wizards up 108-104 with 28.9 seconds remaining. Miller answered with a layup, was fouled but couldn't convert the free throw.
Crawford was fouled by Kosta Koufos and made one of two free throws for a three-point Washington edge with 21.6 seconds left and Miller then scored on a layup with 13.6 seconds remaining.
The Nuggets fouled Beal with 8.6 seconds and he made one of two free throws for a 110-108 lead. Lawson drove the lane but his attempt for a tying layup in the final seconds was blocked by Wall, who added a pair of free throws with 2.7 seconds left to seal the victory.
JaVale McGee, who was acquired as part of the trade that sent Nene to Washington, followed a one-handed dunk off an alley-oop from Brewer with a putback dunk in the last 33.3 seconds of the second quarter, giving the Nuggets a 50-45 halftime lead.
NOTES: Washington's Crawford was back in action after missing four games because of a sore left ankle. He came off the bench and had eight points in just over 17 minutes of play. ... Nuggets had won 24 in a row at the Pepsi Center when scoring 100 or more points before losing to the Wizards.
