Boston played without Friday night's star Marcus Morris, in addition to Kyrie Irving, Marcus Smart and Daniel Theis. Still, Rozier notched 33 points with 8 threes, 5 rebounds, and 5 steals.
His shooting seemed infectious as every Celtics starter shot at least 60% from the floor.
The Kings were equally as hot in the first half, and cashed in on careless turnovers to build an eight-point lead going into the break.
Boston was able to turn it on in the second half to wipe away that deficit, and managed to pull out a convincing win by the final minutes, bolstering the lead up to 11 as the clock ticked away.
Jaylen Brown performed well in his return to action, after a concussion sidelined him for about two weeks. It took him some time to find his footing, as he committed a few turnovers early on, but he still finished 19 points in 25 minutes of play.
The C's will target the Phoenix Suns next as their Western Conference roadtrip continues on Monday night.
