Payton Pritchard played a key role in Boston's convincing victory with 32 points and six made three-pointers. Jayson Tatum added 30 points and 11 assists, while Jaylen Brown contributed 20 more, as the Celtics completely controlled the game and won the rebound battle 51-30.
Philadelphia opened the game brilliantly on the wings of Joel Embiid, who returned just 17 days after appendix surgery. The Cameroonian center scored the first eight points of his team and finished the game with 26 points in 34 minutes, but after a strong start, he failed to maintain the rhythm.
Luka Garza spent 11 minutes on the court and finished the game with 6 points, 3 rebounds, and 2 assists.
Game 5 will be played on Tuesday in Boston, where the Celtics have the opportunity to close out the series in front of their home fans and advance to the second round, where they would face the Atlanta Hawks or the New York Knicks.
