Rajon Rondo  scored 21 points with 12 assists and Kevin Garnett  added 22 points to lead Boston scorers as the Celtics defeated the Cavs by a final score of 94–85 in Game 6 of the best-of-seven Eastern Conference Semifinal Series.
The Celtics win the series 4-2, the second time in the last three seasons that they have sent James and the Cavs packing.
Game 1 of the Eastern Conference Finals will be Sunday at Orlando.
A 10-0 fourth-quarter run by the Celtics was punctuated by a Garnett dunk to give Boston an 88-74 lead with 5:50 left. The Cavaliers made a few small runs, but could never get closer than four points.
James, playing what could be his last game with the Cavs, was sloppy but extraordinarily active, finishing with 27 points (on 8-of-21 shooting) 19 rebounds, 10 assists and nine turnovers. Mo Williams  scored 22 points, but only had two points in the second half.
The Cavs shot only 38.4 percent from the floor in the game and finished with 22 turnovers.
Paul Pierce  struggled in the first half (two points) but had 11 second-half points, including three three-point field goals. Tony Allen  (10 points, strong defense on James) and Rasheed Wallace  (13 points) played well off the bench.
The Celtics led by a score of 51-49 at halftime.
Rondo topped the Celtics with 12 points in the half.
Mo Williams, who had struggled since a big Game 1, was the story for the Cavs in the first half, pacing all players with 20 points. James took 12 shots (just two fewer than Game 5), but made just four. He finished the first half with 12 points, six boards, five assists and four turnovers.
The Celtics had a three-point edge (25-22) after the first quarter. The lead was as large as nine (20-11), but the Celtics made just one field goal in the final 5:11. The Celts shot 55.6 percent in the quarter, led by Garnett, who made all four field-goal attempts to lead all Celtics with eight points. Rondo had five points and four assists, but also turned the ball over four times. The Celtics had six turnovers in the opening quarter, leading to seven Cavs points. That kept the game close as the Cavs shot just 40 percent from the floor.
For the Cavs, Williams led all players with 10 points and James had nine points (on 3-of-8 shooting,) five rebounds, two assists, two steals and three turnovers. That was the story all game for James as he could never find his rhythm.
The third quarter was the game’s most physical, with the Celtics emerging with a 76-67 lead. Plenty of hard fouls and pushing and shoving. Garnett and Pierce each had eight points in the quarter.
