Consecutive turnovers by Terry and Smith led to the game-winning shot. Terry got the ball at the top of the arc and drained a 3-pointer to give Boston the lead.
Smith turned the ball over again and Terry followed with two free throws to seal Boston's victory.
"I think the story of the game for us was turnovers down the stretch. I think that they just killed us. We can't turn the ball over," Horford said.
A tight first quarter that featured nine lead changes ended with the Celtics holding a 28-26 lead.
Boston's margin reached 10 midway through the second stanza. The Celtics ended the frame on a 9-3 spurt to take a 52-47 edge into the locker room.
