MILWAUKEE — For so much of this streak, it has been about winning in a variety of ways for the Miami Heat.

They have done it some nights on talent, some on grit and, at times, simply outlasted the opponent.

Add doing it with anger to the list.

The Heat appeared to see a little red, flaring the nostrils after one of their own went down with an early injury. And even though Dwyane Wade returned from a first-quarter spill, the Heat kept their mean streak going in a 107-94 victory Friday night against the Milwaukee Bucks at Bradley Center.

And as for streaks, that continued, too. Make it 21 straight victories, meaning they have gone six weeks without defeat.

It started so routine for Miami, with Wade scoring an easy layup and Mario Chalmers connecting with LeBron James for an alley-oop for the game’s first four points. It became anything but when the Heat were given their second injury scare in the past three weeks.

With the score 8-4, a driving Wade was met in the lane by Bucks forward Larry Sanders. The shot was blocked, but that was the least of the Heat’s concerns. Wade fell to the floor in pain after taking a hard fall. He was tended to by team trainers, giving Wade tests usually reserved for those who have sustained concussions.

The moment was reminiscent of James having a similar misstep when he landed awkwardly against the New York Knicks earlier this month. Wade left the court with seven minutes, 17 seconds left in the first quarter, only to return midway through the second from what was a termed a neck sprain.

Like James, the injury appeared worse than it actually was.

As was the fear of the streak coming to an end when the Bucks led by one after the first quarter.

Even in their brief stint without Wade, the Heat proved they had more than enough to defeat a Milwaukee team that had beaten them three months ago in what coach Erik Spoelstra called “one of our worst losses of the year.” The Bucks used a 33-5 second-half run to capture a 19-point victory in December.

That was against the old Heat. Not the team that has many wondering when it will lose again.
