Dwyane Wade scored 26 points to lift Miami 89 victory over Washington on Friday.
Chris Bosh scored 24 points to go with 11 rebounds, while LeBron James added 18 points and nine assists for the Heat, who bounced back from a loss at Orlando on Wednesday to win for a fourth time in their past five games.
"We all had a good feel for the ball tonight," said Bosh. "The way you start is usually the way you're going to play for the rest of the night."
"That is a tough team to play over there," said Young. "You can learn a lot playing teams like that."
The Heat held just a seven-point lead, 74-67, heading into the fourth, but Bosh and Mike Miller quickly extended that to 12 points with a jumper and three-pointer, respectively.
Washington tried to keep up and a three-ball from Young with just over six minutes to play made it a 91-80 contest, but Shane Battier, who scored 10 points in the fourth, hit one from beyond the arc and James followed with two from the line for a 16-point edge with 5 1/2 minutes left.
The Wizards never got closer than 15 points the rest of the way.
Washington kept it close through much of the first quarter and the game was tied at 19-all after Jordan Crawford nailed a jumper, but Battier and Dexter Pittman closed the quarter with buckets to give Miami a 23-19 lead heading into the second.
Miami built its lead as high as 12 in the second quarter and eventually took a 52-42 lead into the break.
An 11-0 run in the middle portion of the third quarter helped the Wizards make it a one-point game after Trevor Booker put in a basket, but the Heat would rally and take a seven-point lead into the fourth.
