Evan Fournier scored a career-high 32 points and hit the go-ahead 3-pointer with 56.1 seconds left in the second overtime Wednesday night for the host New York Knicks, who squandered an 11-point lead late in the fourth quarter before edging the Boston Celtics 138-134 in an entertaining season opener for both teams.

Fournier, who spent last season with the Celtics, scored 17 points in the fourth quarter and both overtimes as he became the first player in Knicks history to score 30 points in his debut for the team.
