With New York leading 73-70 shortly after the fourth quarter began, Stoudemire collected a pass from a curling Tim Hardaway Jr. and immediately rose to throw down a vicious right-handed dunk. Hardaway's movement through the paint drew enough attention from Cleveland's defenders that Stoudemire was able to power up over the top of Varejao before the Brazilian big man could effectively contest the shot.
The force of Stoudemire's dunk briefly staggered Varejao, who looked to the referees for a foul call, but play continued.
Stoudemire finished with 18 points and nine rebounds. Hardaway led the Knicks with a team-high 20 pointsand three rebounds off the bench.
Kyrie Irving paced the Cavaliers with a game-high 37 points, three rebounds and two assists. LeBron James added 19 points, 12 assists and five rebounds in the win.
Cleveland improved to 10-7. New York dropped to 4-16.
