The Heat broke open a tie game in the fourth quarter with a 14-point run and LeBron James‘ 35 points helped Miami defeat the Celtics, 102-91, to take a two-game lead in the second-round series. Rajon Rondo led the Celtics with 20 points, 12 assists and six rebounds.

Game 3 is back in Boston on Saturday.

WHAT WENT WRONG

Fourth-quarter collapse: After surging back to tie the game at 80 apiece, the Heat scored the next 14 points, including six free throws, to take a 94-80 lead with three and a half minutes remaining. James dominated that stretch, totaling 12 fourth-quarter points. The Celtics unraveled, failing to get back on defense as a result of complaints about the officiating. Even Doc Rivers picked up a late technical foul arguing a call (the Heat did own a 36-22 advantage in free throws).

Heat’s Big Three vs. Celtics’ Big Four: The Heat entered the game with a 33-3 record when their Big Three combined for 70 points, and James, Dwyane Wade and Chris Bosh combined to top that milestone by 10. Wade, James and Bosh combined for 80 points and 26 rebounds, while Rondo, Allen, Pierce and Garnett totaled 56 points and 22 rebounds. Allen (7 points) and Pierce (11 points) especially struggled.

Paul Pierce isn’t Paul Pierce: Pierce left the game in the first half after twisting an ankle. After getting treatment in the locker room, he returned relatively quickly. Still, he didn’t appear as explosive and struggled for a second straight game. Meanwhile, Allen — who was already struggling — bruised his chest during a third-quarter collision with James.

WHAT WENT RIGHT

Jeff Green inserts himself: In 10 first-half minutes, Jeff Green made 4-of-5 shots — including a pair of 3-pointers for 10 points before the break (he finished with 11 points). His performance highlighted what was perhaps the bench’s best stretch of the playoffs, as the Celtics stayed with the Heat to start a low-scoring second quarter. Green even demonstrated some rare emotion, letting out a roar after being fouled by James in the third quarter. Delonte West (10 points) also had five points on 2-of-2 shooting off the bench during that same span.

Guarding James Jones: After Jones scored 25 points on seven shots in Game 1, the Celtics made a concerted effort to keep Jones from killing them on open 3-point shots — and it paid off. Forcing Jones to play off the dribble rather than set up along the 3-point line, the C’s held him to one missed field goal in the first half. Meanwhile, Jones picked up three fouls on the defensive end before the break — rendering him useless.

JO-ffensive rebounding: The Celtics have struggled on the offensive glass all season, but Jermaine O’Neal single-handedly gave the C’s five extra possessions in the first half alone — as they battled the Heat evenly (7-7) in offensive rebounding for the first 24 minutes. O’Neal finished with a respectable eight points and nine rebounds, but the Celtics ended up losing the rebounding battle on both ends of the floor.
