MIAMI (AP) -- Paul Pierce scored 27 points, Kevin Garnett added 24 points and nine rebounds, and the Boston Celtics made their first eight shots of the fourth quarter to hold off the Miami Heat 115-107 on Tuesday night.
Rajon Rondo posted double-digit assists for the 18th straight game, extending the NBA's longest such streak in 20 years with an 18-point, 15-assist effort.
LeBron James finished with 36 points, seven rebounds and seven assists for Miami, which got 20 from Dwyane Wade and 18 from Mario Chalmers.
The Celtics beat Miami 91-72 in Boston on April 1, a game the Heat called "unacceptable."
This one won't sit any better with the reigning Eastern Conference champions, who ousted the Celtics in five games from last year's playoffs and could see them in the second round of the upcoming postseason.
