Miami has won four of its past five games, and is coming off a 118-95 victory on Tuesday night against the Bucks.

"It wasn't perfect," Heat coach Erik Spoelstra said. "There were still some areas we definitely need to improve on, in terms of the details and discipline. But at least the effort, the effort, the activity was better, the disposition right from the beginning and it carried through once we got into the rotation."

Reserve Michael Beasley scored 19 points as Miami (5-3) shot a season-best 58.2 percent. He stepped it up as LeBron James was forced to 30 minutes of action as he deals with a sore back.

"It means that my hard work is not going to vain,"Beasley, who has scored 29 points his last two games  said. "I'm doing it to help my teammates because at the end of the day I don't want to let those guys down."

As the offense of Dallas is much improved than years past, the defense is starting to come together as well. The Mavericks are forcing 18.8 turnovers per game, third-most in the NBA, and using those extra offensive possessions to pull away from opponents.

"We're getting better each and every game," Mavericks reserve forward Vince Carter told the team's official website. "Our rotations are better. Our individual defense has been better. But just more than anything our help side and our team defense has been better, and it's fueled our offense."
