The away team got the first field goal at 3:22, a 3-pointer by Victor Oladipo. The Celtics led 29-11 in the first quarter. With Miami’s offense unable to penetrate a defense bolstered by the return of Robert Williams, the Celtics kept the pressure on in the second quarter, extending the lead to 27 points.
