Paul Pierce scored 27 points,
Kevin Garnett added 24 points and nine rebounds, and the Celtics made their first eight shots of the fourth quarter to hold off the Heat 115-107.
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. Brandon Bass added 12 points and 10 rebounds, while Avery Bradley scored 11 for the Celtics, who shot a season-high 61 percent and survived two possessions where Miami could have tied the score in the final quarter.
LeBron James finished with 36 points, seven rebounds and seven assists for Miami, which got 20 from
Dwyane Wade and 18 from
Mario Chalmers. Chris Bosh finished with 13 on 5-for-13 shooting for Miami, which has gone 5-5 in its last 10 games.
Miami had two shots to tie early in the fourth after being down by as many as 18 earlier, before Garnett made jump shots on four straight possessions, the average length of those makes being 19 feet.
A 10-0 run early in the first quarter gave Boston a quick lead - and that wasn't even the Celtics' best run of the opening period. Boston scored the last 11 of the first, the run actually becoming 13-0 when Garnett scored to open the second quarter, and Boston's lead was 35-22.
Everything the
Celtics wanted, they got. Boston shot 61 percent in the first quarter, 62 percent in the second. Rivers used eight players, all of them making multiple shots by halftime. Of them, the only one who failed to make at least half his shots was Bass, who more than made up for that with six first-half rebounds.
Here's how well the
Celtics were shooting:
Miami went into the break shooting 51 percent from the field, 60 percent from 3-point range and 78 percent from the foul line - and Boston was at least 10 percentage points better in every department.
Down by 18 in the first half, Miami cut the deficit to 65-57 at halftime. James closed it with a 3, punching the air as the shot dropped.
Even with that, every moment of the second half was an mounting combat
And the Celtics weren't being caught.
Miami got within five twice in the third, with Rondo answering both times to make it a three-possession game again. The Celtics held the Heat to 36 percent shooting in the quarter, keeping the eight-point lead entering the fourth at 89-81.
The Heat had two chances to tie early in the fourth, after starting the period on a 7-0 run. The first of those slipped away when Bosh failed to finish off a three-point play opportunity by missing from the line. The next came when
Udonis Haslem missed from the left baseline with 9:17 left, and Boston's answer that time was absolute.
Allen made a catch-and-shoot 3 for a 94-89 lead, and then Garnett just took over.
