Marcus Smart hit Jayson Tatum for a cutting layup with zero seconds left on the clock, and the second-seeded Boston Celtics beat the Brooklyn Nets 115-114 in Game 1 of their first-round playoff series.
The bucket spoiled Nets star and Boston villain Kyrie Irving's game-high 39 points.
The Celtics led by as many as 15 points, and Kevin Durant had an uncharacteristically poor outing for the Nets, but Irving led a comeback in the face of a hostile crowd. The fans provoked him, and he provoked them, flashing them a middle finger in the third quarter.
