Celtics guard Dionte Christmas scored 19 of his 21 in the first half, helping the Celtics build a double digit lead by the break. Second-year guard E'Twaun Moore had 18 points on six-of-10 shooting.
Rookie Jared Sullinger was held out of the game.
Justin Harper, continuing to make the transition to small forward, led the Magic in scoring for the second straight, but again really struggled from the field. A day after shooting six-of-18, he shot just six-of-17 from the field Friday.
Former South Dakota guard Charlie Westbrook had the highlight of the day, faking Jamar Smith into falling down, then hitting a jump. Westbrook scored 14 points on six-of-seven shooting.
Andrew Nicholson had a rough day, putting up four points and grabbing four rebounds while fellow rookie Kyle O'Quinn scored six points and grabbed nine rebounds.
