TORONTO -- The Miami Heat were given a bit of a scare in the fourth quarter by the Toronto Raptors but were virtually unstoppable late and won their 22nd-consecutive game with a 108-91 win over the Raptors.
The Heat built up a 16-point lead in the first half but the Raptors chipped away and tied the game early in the fourth quarter before Miami pulled away down the stretch.
Dwyane Wade had 24 points to lead all scorers while LeBron James had 22. Rudy Gay and Amir Johnson were responsible for most of the Raptors scoring. Gay had 27 while Johnson had 18 to go along with 18 rebounds.
Toronto tied the game at 77-77 when Gay hit a pair of free throws at 11:08 in the final quarter, but the Heat responded with 12-straight points, including a highlight-reel dunk from Wade off a half-court lob from Norris Cole.
The Heat outscored Toronto 31-14 after Gay tied the game.
DeMar DeRozan had just two points in the first half but came to life in the third quarter as the Raptors made things interesting heading into the fourth.
Toronto finished the third on a 7-0 run with DeRozan responsible for all the scoring, including a pull-up 17-foot jumper with the final possession of the quarter.
With the Heat up by eight points at the start of the second quarter, the teams traded baskets and there was little change to the Heat's advantage for the first few minutes.
The Heat then started to pull away and Wade hit a driving lay-up with 5:12 remaining to put Miami up by 16-points at 43-27.
With just under two-minutes remaining, Terrence Ross scored with a layup then a dunk on back-back possessions to reduce the deficit to 10 at 49-39. The Raptors would further close the gap to nine points before James hit a 3-pointer with the final shot of the half to put Miami up 55-43.
The Heat shot 57.9 percent in the first quarter and that allowed them to build up a 27-19 lead after the first.
