Boston guard Marcus Smart led all scorers with 19 points, including back-to-back treys in the fourth quarter to give Boston a four-point lead with 3:43 to go.
Starting at point guard for Orlando, Elfrid Payton contributed eight points, nine rebounds, and 10 assists in 31 minutes, controlling the game despite rarely seeking his own shot. Seth Curry sparked Orlando in the second period by scoring eight of his 15 points off the bench, helping Orlando take a 32-29 lead into intermission.
Back-to-back driving scores by Payton capped a 10-point Magic run to start the second half, but Boston responded out of a timeout. It reeled off 12 straight points of its own as it dominated the Magic in the paint, scoring two and-ones on layups and another inside basket.
A pull-up jumper from Cameron Jones gave Orlando a five-point lead, but it never extended beyond that. Celtics swingman Chris Johnson nailed a jumper early in the fourth quarter to give Boston a lead it wouldn't relinquish as Orlando, perhaps fading due to tired legs, went cold from the field.
Magic forward Aaron Gordon, the fourth overall pick in the 2014 NBA Draft, shot 3-of-10 for seven points and eight rebounds. Second-round choice Devyn Marble missed all seven of his shot attempts, but stayed active by adding seven boards from the wing.
