BOSTON -- Miami's Big Three was assembled for just this purpose: To dominate the bullies from Boston who knocked them from the playoffs so many times before.
LeBron James scored 35 points, Dwyane Wade had 28 and Chris Bosh had 20 on Monday night to give the Heat a 98-90 overtime victory over the Celtics and move Miami within one game of the Eastern Conference finals. The Heat lead the best-of-seven East semifinals 3-1, with a chance to close out the series in Miami on Wednesday.
"Wednesday night will be our greatest challenge that we've had with this group so far," Miami coach Erik Spoelstra said. "We'll get their best games on Wednesday. And we have to be better. If we're real about what we want to do, we have to beat the Boston Celtics at their best."
One game after their worst performance as a threesome, James, Wade and Bosh had 83 of Miami's 98 points and 35 of its 45 rebounds. They scored all 12 of Miami's points in overtime; Bosh and Wade had five apiece after James' jumper on the Heat's first possession of the extra period game them the lead for good.
"He had some incredible 'will' plays there in the fourth quarter and overtime," Spoelstra said. "We needed every bit of his talent and competitive will."
Paul Pierce scored 27, Ray Allen had 17 and Kevin Garnett had seven points and 10 rebounds for Boston, which eliminated Miami from the playoffs last season one round after knocking James and the Cavaliers out for the second time in three years. The Celtics would need to win the next three games -- two in Miami -- to have a chance to defend their Eastern Conference championship.
"These are those moments. I look forward to it," Allen said. "Everybody on this team, we know what to do. We can't talk about it; we just have to put our best foot forward. It's not easy."
The Celtics scored just four points in overtime, shooting 1 for 6 and making four of their 18 turnovers. Garnett started things off by throwing the ball away, and then James made a fallaway jumper as the shot clock expired to give Miami an 88-86 lead.
Rajon Rondo, who dislocated his left elbow Saturday night in Game 3, played 39 minutes with a padded sleeve covering what appeared to be a brace on his left arm, scoring 10 with five assists.
