The Celtics held off a typically spirited charge by the Heat in the second half of Friday’s game to claim a 111-104 victory.
Here’s what happened as last year’s Eastern Conference finalists matched up for the first time in the regular season.
The big picture
The Celtics got contributions across the board in the first quarter, as units led by Jaylen Brown spent most of the period building an eight-point advantage. Tyer Herro helped the Heat stay afloat with 13 second-quarter points, but the Celtics maintained their eight-point lead going into halftime thanks to 25 combined points between Brown and Tatum.
