Raymond Felton had 13 points and 14 assists for the Knicks, who seized control with a 16-2 run spanning the third and fourth quarters and beat the Heat for the fourth time in five meetings over the last two seasons.
New York was second to Miami in the Eastern Conference last season when it won the series 3-1, but there was little reason to suggest the Knicks were ready to compete with the NBA champions this season. New York is only 13-22, though it has won four of five in 2014.
