Philadelphia maintained control into the fourth quarter.

A jumper by Jaylen Brown cut the 76ers’ lead to 91-89, but Philadelphia responded with 3-pointers from Tyrese Maxey and VJ Edgecombe to extend the lead. Maxey and Edgecombe combined for 59 points.

The Celtics ended the game shooting 13 for 50 (27%).

“We just got to watch the film and make adjustments,” Brown said. “They’ve got some good basketball players over there, I thought we got to do a better job on Edgecombe.”

Brown led Boston with 36 points.

The series now shifts to Philadelphia for Game 3 on Friday at Xfinity Mobile Arena.
