The New York Knicks defied the odds Monday at TD Garden, coming back from a 20-point deficit and outlasting the Boston Celtics 108-105 in overtime of Game 1 of the Eastern Conference semifinals. The Knicks went on a 25-9 second-half run to cut the Celtics’ lead to four points with roughly 9 minutes left to play.

The Knicks came from 20 points down to force overtime and beat the Celtics, who had a terrible night from 3-point land, in Game 1 of their series.

The Celtics entered the game as a favorite but a bad shooting night doomed them. The team went a putrid 15-of-60 from beyond the arc, with stars Jayson Tatum and Jaylen Brown combining to go 14-of-43.
