LeBron James and the Cleveland Cavaliers turned a close first half into a laugher Tuesday night winning against Eastern rivals Boston Celtics, 89-77.

The Celtics actually had the lead at the halftime break, 46-40 but James and the Cavs turned in a 29-15 third quarter and opened up the game to notch the blowout victory, their third in a row after three straight losses to start December.

James scored a game-high 24 points on 10-of-20 field goals and added 7 rebounds and 2 steals while Kevin Love contributed 20 points, 8 rebounds and 5 assists. Timofey Mozgov added 9 points, 10 rebounds and 3 blocked shots while Mo Williams had 10 points off the bench.

The Celtics, who are just 3-3 in their last six games, shot just 32.2 percent from the field (28-of-87 field goals) and 28.1 percent from behind the arc (9-of-32 three-point field goals). Avery Bradley led the way for Boston with 17 points while Jae Crowder and Isaiah Thomas added 14 and 12 points, respectively but no other Celtic finished in double-figure scoring.

James and the Cavaliers will bring the momentum of the three-game win streak when they face Kevin Durant, Russell Westbrook and the rest of the Oklahoma City Thunder for a marquee match-up in Cleveland Thursday.

Meanwhile, the Celtics will travel to face the Detroit Pistons Wednesday before a two-game home stand against the Atlanta Hawks and Minnesota Timberwolves.
