The defending NBA champions held off the league’s hottest team on Tuesday night, with Jayson Tatum scoring 33 points and adding 12 rebounds to lead the Boston Celtics to a 120-117 victory over Cleveland and hand the Cavaliers their first loss after 15 straight wins to open the season. Cleveland cut a 21-point deficit to two in the third quarter, and Donovan Mitchell hit a rainbow 3-pointer with 24 seconds left to make it a four-point game. Tatum sank one of two free throws, and then clobbered Mitchell at the other end, leaving the Cavaliers guard on the floor in need of medical attention.
