Heat 120 Celtics 107: Dwyane Wade led with 29 points and Ray Allen added 19 off the bench in his first meeting against his former team as host Miami received its championship rings and then dispatched Boston.

LeBron James left early in the fourth quarter with leg cramps but ended up with 26 points on 10-of-16 shooting and 10 rebounds for the Heat, who shot 54 percent from the floor and scored at least 27 points in every quarter.

Newcomer Jason Terry and holdover Jeff Green, who missed all of the 2011-12 campaign after heart surgery, combined to shoot 2-for-11.
