Washington made its first seven three-pointers while holding Miami to 2 for 22 from beyond the arc for the game, and John Wall finished with 18 points and 13 assists to lead the host Wizards past the Heat, 107-86, on Monday night.
Rasual Butler scored 23, and Marcin Gortat added 15 points and 10 rebounds for the Wizards, who never trailed and led by 21 in the first half and 25 in the second.
Chris Bosh led Miami with 21 points, and Dwayne Wade had 20 in his second game back from an injured right hamstring.
A night earlier, Wade returned after missing seven games and scored 27 points in a victory at New York.
He played 32 minutes in that game, and 27 on Monday.
The Heat came into the game leading the NBA in three-point shooting at 38.6 percent, but they made only 9.1 percent this time. They opened the game going 0 for 8 from three-point range. Bosh finally ended the game-opening drought by making a trey with about six minutes left in the first half.
Nuggets 103, Jazz 101 - Ty Lawson had 15 points and made a double-pump jumper to beat the shot clock with 29.6 seconds left that boosted Denver over host Utah in a charged atmosphere.
The game heated up after Arron Afflalo was ejected and the Jazz stormed back from a 22-point deficit to tie the game in the final minutes.
Lawson, who also had 12 assists, made the game-winner from the left wing between two Jazz defenders.
