Winning in Cleveland was important to the Celtics , but Doc Rivers knew  beating the Celtics at home would be significant to the Cavaliers , too. On Sunday, the Cavs defended their homecourt (where they are now 29-4) and defeated the Celtics, 104-93.
LeBron James  scored just two field goals in the first quarter and had six points in the entire first half, but finished with a game-high 30 points.
The Big Three tried to carry the Celtics offensively — Ray Allen  led with 20 points; Kevin Garnett  and Paul Pierce  followed with 18 each. Rajon Rondo  led the C’s with eight boards, but the team was outrebounded 51-43.
Turning Point: The Celtics had an opportunity to reclaim control of this game in the third quarter. Allen and Pierce tied the game at 68 apiece with back-to-back 3-pointers. But Garnett and Rondo committed a pair of turnovers in 24 seconds and the Cavs went on an 8-0 run.
Player of the Game: After Saturday’s practice, Kendrick Perkins said  Anderson Varejao was an instigator on the court, and he proved to be on Sunday. Varejao scored 15 points and grabbed 6 rebounds off the bench in the first half alone. His tough play early on set the tone for the Cavaliers.
– Garnett and Glen Davis  were both involved in rough play during the game. Early in the first, Garnett and J.J. Hickson were called for technical fouls after exchanging words under the basket. In the third, Garnett went for the ball and ended up hitting James in the face. James fell to the ground and had to go to the bench during a subsequent timeout. As for Davis, he practically leapt at Antawn Jamison  and knocked him to the floor while attempting a 3-pointer.
– One of the reasons why the Celtics were able to stay in the game was because of free throw shooting. They shot 23-for-30 from the line while the Cavs were 31-for-48.
– The Celtics shot 0-for-6 from 3-point range in the first half, but went 6-for-11 in the second. Allen and Pierce hit three apiece.
– Former Celtic Leon Powe  scored six points and grabbed four rebounds in eight minutes for the Cavs.
