Tatum’s first career 40-point performance helped the Celtics snap a season-high, three-game losing streak. He became the second-youngest Celtic to score 40+ points in a game (Antoine Walker).
Boston shot 14 of 29 from the 3-point line and tied a season high for points.
New Orleans played without Derrick Favors because a right hamstring strain, Jrue Holiday sat his fourth straight game with a left elbow contusion, Kenrich Williams missed his third consecutive game with back soreness and J.J. Redick sat with a left hamstring strain.
Hayes and E’Twaun Moore started in place of Williams and Favors.
The Celtics exploited the absences early. Tatum was active from a variety of spots on the floor, connecting on eight of his first nine shots. He scored 22 points in the the first half to help the Celtics build as much as a 22-point lead.
