BOSTON — Jaylen Brown scored 31 points and hit three 3-pointers, and the Boston Celtics broke the NBA record for 3-pointers in a season in a 123-103 victory over the Phoenix Suns on Friday night.

Boston was 14 of 39 from 3-point range to push its season total to 1,370. Golden State held the previous record with 1,363 in 2022-23.

After having their nine-game winning streak halted in their previous game, the Celtics coasted to the victory.

Jayson Tatum added 23 points, eight rebounds and eight assists. Kristaps Porzingis had 15 points before he walked to the locker room holding a towel to the bridge of his nose early in the final quarter after getting hit by Cody Martin’s elbow while the Suns player was driving to the basket.

Porzingis raised both arms and waved to the crowd as he headed into the tunnel. He returned to the bench late in the game, and the team said the cut required stitches.

Devin Booker led the Suns with 37 points. Phoenix has lost five straight.

Boston opened a double-digit edge on Payton Pritchard’s 3-pointer early in the second quarter, pushed it to 20 midway into the quarter, and led by 14 at halftime.

Boston beat the Suns by 30 points in Phoenix during a 6-0 road trip just over a week ago.

Celtics: At times, Tatum, Brown and Porzingis seem like they can take turns scoring against certain teams.
