Despite being out-rebounded 51-26 (they allowed a whopping 24 offensive boards), the Heat were able to come out on top, shooting a sizzling 58.2 percent from the floor and ramping up their defensive effort late in the game to snuff out the Raptors' comeback attempt.
The game was tied at 77 early on in the fourth before Miami took over.
Rudy Gay led all scorers with 27 points, and Raptors teammate Amir Johnson had an impressive performance of his own, going for 18 points and 18 rebounds. Dwyane Wade paced the Heat with 24 points, while LeBron James finished with 22.
The Heat will now have to prepare for a showdown with the Boston Celtics at TD Garden on Monday night.
