BOSTON — Jayson Tatum scored 36 points and Jaylen Brown had 30 points and 10 rebounds before both rested the entire fourth quarter as the Boston Celtics routed the Sacramento Kings 128-75 on Tuesday night.

Robert Williams finished with 13 points and 17 rebounds for the Celtics, who got off to a torrid start and never let up on the Kings, even when both teams went to reserves for the fourth quarter of a game that had been long decided. Boston stretched its lead to 60 points before it was over.

Buddy Hield led the Kings with 11 points. He was the only Sacramento player to score in double figures as the Kings lost their fourth straight. Richaun Holmes had nine points and nine rebounds and Tyrese Haliburton added seven assists for Sacramento.

The Celtics went on an 11-0 run early in the first quarter, then added a 16-0 spurt later in the period while holding the Kings scoreless for a stretch of 5:05. Boston led 38-13 after one.

Brown alone outscored Sacramento with 15 points in the first quarter and had a nice assist with a long bounce pass to set up Robert Williams for a dunk. Grant Williams also hit a 3-pointer during the 16-0 run and grabbed his own rebound after a miss and put it back up for a layup that Maurice Harkless blocked but was called for goaltending, putting Boston up 33-7.

A 3-pointer by Josh Richardson with 1.1 seconds left in the second quarter gave Boston a 63-30 halftime lead. It was the third straight game the Kings allowed 60 points in the first half.

Brown opened the third quarter with a 15-foot jumper, then hit back-to-back 3-pointers. He finished the game 11-for-19, making 5 of 12 3s.
