Lin made only 4-of-17 attempts from the field, but his free-throw shooting assured the Knicks their fifth straight win. New York is in the eighth spot in the Eastern Conference playoff race.
Lin had 18 points and the last of his free throws with 13 seconds left put the Knicks on top by six. Jodie Meeks hit a 3-pointer for the 76ers just before the buzzer to account for the final score.
Jrue Holiday had 16 points to lead Philadelphia, which has lost four out of five. The 76ers' lead in the Atlantic Division was cut to a single game over idle Boston.
Philadelphia had to play catchup after an ugly first period that saw the 76ers miss their first 14 shots and score only 11 points.
