The AP reports:  Kevin Garnett had 15 points and nine rebounds and the Boston Celtics played Miami-style defense to beat the Heat 85-76 in the opener of their playoff series Saturday night. Trailing 44-41 at halftime, the Celtics held the Heat to 32 points in the second half. And with substitute guard Tony Allen shadowing Dwyane Wade, the Heat star scored 26 points after averaging 33.7 in three regular-season games against Boston… With 40 seconds left in the game, a scuffle near the Miami bench resulted in two technical fouls against Garnett, an automatic ejection, and one each to Boston’s Glen Davis and Miami’s Udonis Haslem and Richardson.
