SERIES NOTES:

After Game 7: The Boston Celtics visited and defeated the Miami Heat 100-pts-96 to complete a 4-games-3 best-of-7 MLB/NBA/NHL playoff series 1512 victory. With the series 1512 win, the Boston Celtics improve their best-of-7 NBA playoff series record to 72-30 overall and 21-12 in the Semifinals round.

The win order for the victorious Boston Celtics in series 1512 was LWLWWLW: Series 1512 thus becomes the third NBA Semifinals-round series, the tenth NBA series (all rounds), and the 28th MLB/NBA/NHL series (all rounds) to follow that win order to completion. The series 1512 Game 7 victory by the Boston Celtics is their best-of-7 MLB/NBA/NHL-leading 26th Game 7 victory; tied for second place in Game 7 wins irrespective of site are the NHL Boston Bruins and the NHL Montreal Canadiens with 15 Game 7 wins each.

The series 1512 win by the Boston Celtics snaps their four-series losing streak in best-of-7 NBA Semifinals series; the series 1512 loss by the Miami Heat snaps their six-series winning streak in best-of-7 NBA Semifinals series and their four-Game 7 winning streak at home (all rounds).
